Full textSUMMARY This study evaluated the in vitro influence of the storage manner and two kinds of dentinal adhesive on the microleakage, in axial and cervical walls of composite restorations, in primary second molars. The samples were divided in three groups, according to the storage manner, and named: Desidratado, Hidratado and Congelado. The samples of the Desidratado group were kept dry, the ones of the Hidratado group were stored into phisiological saline solution under refrigeration, and the ones of the Congelado group were kept into the freezer, also immersed into the phisiological solution. Then, the samples received two vertical slot preparations, one mesio-occlusal and the other disto-occlusal. On the mesio-occlusal cavities, the adhesive system Scotchbond Multi-Uso was used, whereas on the disto-occlusal the monocomponent adhesive Prime & Bond 2.1 were chosen, and all of them were filled with the Solitaire composite. The groups were then thermocicled, before immersion in silver stain solution. In order to evaluate the infiltration of the stain in the tooth-restoration interface, the samples were sectioned, first in the vestibulo-lingual direction, and then included into auto-cure resin to the addaptation onto the secctining machine and receive a second cut in the mesio-distal direction, on the center of the restoration. The microleakage values of the axial and cervical walls were measured by a digitalized image system, presented in milimeters, and submitted to statistical analysis. The obtained results showed that the storage manner has no statistically significant influence on the marginal microleakage of the restorations, however, the microleakage of the cervical wall was significantly greater than of the axial wall, with 99,9% certainty. The used adhesive systems have not shown significant influence on the microleakage, in the studied storage manners. However, there was a statistically difference in the Desidratado group samples, with the Prime & Bond 2.1 adhesive, taking in count the margins of the restoration (axial and cervical).

Introdução: O Tratamento Restaurador Atraumático (ART) compreende medidas preventivas, terapêuticas e restauradoras para a prevenção e manejo da doença cárie. Nos últimos anos, a melhoria dos materiais restauradores mais indicados para a técnica (cimento de ionômero de vidro de alta viscosidade, CIV) levou a bons resultados, porém ainda com espaço para desenvolvimentos. Em virtude de limitações dos CIV, novos materiais restauradores adesivos, como as resinas compostas bulk fill utilizadas juntamente com sistemas adesivos autocondicionantes, passam a se apresentar como alternativas para uso na técnica ART. Objetivo: Comparar resultados imediatos (tempo e satisfação do paciente) de restaurações ART em lesões cariosas de rasa e média profundidades utilizando uma resina composta bulk fill associada a um sistema adesivo autocondicionante – protocolo BF, ou um cimento de ionômero de vidro de alta viscosidade – protocolo CIV. Métodos: 155 crianças entre 7-8 anos de idade, com lesões cariosas de extensão radiográfica não invadindo a metade interna da dentina em dentes vitais e assintomáticos, foram randomizadas nos protocolos BF ou CIV. 270 restaurações (BF, n=78 e CIV, n=77) foram realizadas por dois dentistas treinados. O acesso às lesões e a remoção de tecido cariado foram realizados apenas com instrumentos manuais. As cavidades foram restauradas com resina composta bulk fill (BF, Filtek Bulk Fill Posterior, 3M ESPE) ou com cimento de ionômero de vidro de alta viscosidade (CIV, Equia Forte, GC). Foram registrados dados imediatos pós-tratamento relacionados ao tempo de execução e à satisfação dos pacientes (escala de face de Likert de 5 pontos). Os dados foram analisados estatisticamente por modelos lineares generalizados mistos. Resultados: Não houve diferença estatisticamente significativa entre os tempos de tratamento [Média (95% CI), BF: 357,06s (330,96-383,15) e CIV: 332,26 (313,57-350,94). A satisfação dos pacientes pós-tratamento foi elevada (pontuação mediana 1: muito satisfeito) para ambos os protocolos, sem diferença estatisticamente significativa entre eles (p=0,653). Conclusão: Não houve diferenças estatisticamente significativas entre os protocolos BF e CIV no que diz respeito ao tempo de tratamento e satisfação dos pacientes. A longevidade das restaurações e possíveis complicações serão analisadas nos períodos de acompanhamento do estudo clínico randomizado.
Background: The Atraumatic Restorative Treatment (ART) comprises preventive, therapeutic and restorative measures for the prevention of dental caries. In recent years, an improvement in the restorative materials most suitable for the technique (glass ionomer cement, GIC) has led to good results, although there is room for improvement. Due to limitations of the GIC, other adhesive restorative materials, such as bulk fill composite resins along with self-etching adhesive systems, are presented as alternatives for use within the ART technique. Aim: To compare the immediate results of ART restorations in shallow and medium depth carious lesions using a composite bulk-fill resin associated with a self-etching system - BF protocol, or a high viscosity glass ionomer cement - GIC protocol. Methods: 155 children between 7-8 years of age, with non-invasive radiographic extension carious lesions of the inner half of the dentin in vital and asymptomatic teeth, were randomized in the BF or GIC protocols. 270 restorations (BF, n = 78 and GIC, n = 77) were performed by two trained dentists. Access to lesions and removal of carious tissue were performed only with manual instruments (ART). The cavities were restored with bulk fill composite (BF, Filtek Bulk Fill Posterior, 3M ESPE) or high viscosity glass ionomer cement (CIV, Equia Forte, GC). Immediate posttreatment data related to time of procedure and patient satisfaction were recorded (5-point Likert face scale). The data were statistically analyzed by generalized linear mixed models. Results: There were no statistically significant differences between treatment time [Mean (95% CI) BF: 357,06s (330.96 to 383.15) and CIV: 332.26 (313.57 to 350.94). Post-treatment patient satisfaction was high (median score 1: very satisfied) for both protocols, with no statistically significant difference between them (p = 0.653). Conclusion: There were no statistically significant differences between the BF and CIV protocols regarding the time of treatment and patient satisfaction. The longevity of the restorations and possible complications will be analyzed during the follow-up periods of the randomized clinical trial.

Full textThe aim of this in vivo study was to assess the effect of pit and fissure sealants in arresting dentinal caries lesions compared to conventional restorative treatment. Forty two primary teeth from thirty six patients had been selected. Inclusion criteria considered the presence of one or more primary molars with occlusal carious lesion reaching dentine with an opening in enamel not wider than 3 mm diameter, measurement obtained with a millimeter probe. Radiographically, the lesion should be in the outer half of dentine. The patients were randomly allocated in two groups: restoration with composite resin, after partial removal of the carious dentine (control group) and sealant application (experimental group). The patients were submitted to clinical and radiographic (bitewing) evaluation after 6, 12 and 18 months. The scores for clinical assessment were: total retention, considered as success or partial and total loss considered as failure. When integrity failures were found during the follow-up visits, the reapplication (repair) of the sealant was done, but the tooth was excluded from future analysis. In radiographic method, teeth were classified as absence or presence of caries progression. One tooth per patience was randomly selected for statistical analysis. Six exfoliated teeth were collected and processed for scanning electron microscopy (SEM) analysis. Kaplan-Meier survival analysis, Fisher\'s Exact test and logistic regression test were calculated in each evaluation period (p<0.05). Control group showed better results after 18 months with regard to clinical evaluation (p=0.0025). In both groups, all cases showed no signs of carious progress in the radiographic exam for all periods of assessment. The interface tooth / restorative material analysis by SEM allowed a qualitative evaluation of the hybrid layer and adhesive system tags formation, as well as the visualization of bacteria in infected and affected dentin. The experimental group showed more areas of interfacial gaps between the sealant and dentin, while in the control group we observed the formation of more homogeneous hybrid layer tags of adhesive system in affected dentin. We conclude that, although failures were observed, the pit and fissures sealant may contribute to dentinal caries lesion arrestment in primary teeth, as long as it is repaired, consisting in a more conservative treatment than conventional restoration.

Full textThe purpose of this study was evaluation in vitro of marginal microleakings, present on gums edges of class II cavities of deciduous molars, restored with composite resin (auto and light-cured), with the use of a staining solution to verify the leaking. Cavities prepared presented enamel on gums edges and were restored according to four different techniques: lightcured composite resin; auto-cured composite resin; mixed technique (auto and light-cured composite resin) and glass-ionomer/composite resin. Next, we proceeded to thermo-cycling (5°C and 55°C, 700 cycles), turning impermeable, immersion in staining solution and slicing. The microleaking evaluation was done according to a pre-established scale (from 0 a 4 degrees). After the statical analysis of the results, it was concluded that all the groups presented microleaking, in varying degrees. However, the groups which used the mixed technique and light-cured resin presented the smallest levels of leaking, and microleaking was not observed on the auto-cured composite resin/light-cured composite resin edge.

Este estudo avaliou a dentina infectada de dentes decíduos antes e após selamento cavitário, com critérios clínicos (cor, consistência e fluorescência dentinária) e laboratoriais (avaliação microbiológica, ultraestrutural, mineral e imunohistoquímica). As condições clínicas e radiográficas também foram verificadas ao longo do tempo por um período médio de 11 meses. Foram selecionados 45 molares decíduos com lesões de cárie ativa e sem sinais ou sintomas de patologias pulpares. A dentina infectada foi dividida em duas partes para avaliação e remoção de fragmentos em momentos distintos: antes do selamento cavitário (porção mesial) e 60 dias após restauração (porção distal). Escores foram utilizados para registro da cor e da consistência dentinária e a fluorescência foi medida com equipamento DIAGNOdent 2095. Fragmentos de dentina cariada foram coletados para as análises microbiológica (total de viáveis), ultraestrutural (MEV); de conteúdo mineral (MEV/EDS - cálcio, fósforo e flúor) e imunohistoquímica (expressões de MMP- 2, MMP-8, MMP-9, colágeno tipo I e sialoproteína óssea [BSP]). As cavidades foram restauradas com cimento de ionômero de vidro (CIV) de alta viscosidade e reabertas após 60 dias, repetindo-se as mesmas análises, porém na porção distal. A remoção de tecido cariado foi restrita à coleta dos fragmentos necessários para os estudos, os dentes foram novamente restaurados com CIV e acompanhados clínica e radiograficamente. As características das restaurações foram avaliadas pelos critérios do United States Public Health System. Técnicas de subtração radiográfica em radiografias padronizadas permitiram definir diferenças no conteúdo mineral da dentina cariada mantida sob a restauração ao longo do tempo por meio de variações nos tons de cinza. Os dados referentes à cor, consistência, fluorescência e total de bactérias viáveis foram submetidos ao teste de Wilcoxon; as porcentagens em peso de cálcio, fósforo e flúor, assim como as expressões de MMP-2, MMP-8, MMP-9, colágeno tipo I e BSP foram comparadas por meio do teste t pareado; as características das restaurações após 10-13 meses de acompanhamento foram verificadas com o teste de McNemar; as variações nos níveis médios de cinza ao longo do tempo foram avaliadas com o teste ANOVA dois critérios para medidas repetidas (α= 0.05). Após 60 dias de selamento cavitário, as amostras de dentina infectada apresentaram valores mais baixos de fluorescência dentinária (p<0.0001) e total de microorganismos viáveis (p<0.0001), assim como um aumento na consistência (p<0.0001), nos conteúdos de cálcio (p=0.001) e fósforo (p=0.002) e na expressão de MMP-8 (p=0.018), colágeno tipo I (p=0.040) e BSP (p<0.001). Não foram detectadas diferenças significativas na cor, conteúdo de flúor e expressões de MMP-2 e MMP-9. As alterações ultraestruturais foram evidentes, mostrando poucas bactérias e melhor organização tecidual com estreitamento de túbulos dentinários e dentina intertubular mais compacta e mineralizada. Após 10-13 meses de acompanhamento, as restaurações mostraram-se clinicamente adequadas, com alterações detectadas apenas para descoloração cavosuperficial (p=0.008), desgaste (p<0.001) e textura superficial (p<0.001). A subtração radiográfica demonstrou que as médias dos tons de cinza em dentina sadia e cariada aumentaram (p<0.001). Conclui-se que o selamento de dentina decídua infectada promove a reorganização tecidual e favorece a remineralização da dentina cariada remanescente, num processo que se mantém contínuo ao longo do tempo.
This study evaluated the infected dentin from deciduous teeth before and after cavity sealing, using clinical criteria (dentin color, consistency and fluorescence) and laboratorial criteria (microbiological, ultra-structural, mineral and immunohistochemical evaluations). Clinical and radiographic aspects from the treated teeth were also assessed after a mean period of 11 months in oral function. Fourty-five deciduous molars with active caries lesions and without signs or symptoms of pulp pathologies were selected. The infected dentin was divided in two portions for evaluation and removal in different moments: before cavity sealing (mesial portion) and 60 days after restoration (distal portion). Scores were used to register dentin color and consistency; dentin fluorescence was measured with DIAGNOdent 2095. Carious dentin samples were collected for microbiological analysis ( total viable counts), ultra-structural (SEM) and mineral analysis (SEM/EDS - calcium, phosphorus and fluoride) and immunohistochemical assays (expressions of MMP-2, MMP-8, MMP-9, type I collagen and bone sialoprotein [BSP]). The cavities were restored with high viscosity glass ionomer cement (GIC) and reopened after 60 days, when the same tests were done in the distal portion. After removal of the caries samples needed for the different analysis, the teeth were restored with GIC again and were clinical and radiographic followed-up. The characteristics of the restorations were evaluated using United States Public Health System criteria. Radiographic subtraction techniques in standardized radiographics allowed the detection of differences in the mineral content from the carious dentin bellow restoration over time, using the evaluation of gray levels changes. Data from dentin color, consistency, fluorescence and total viable counts were analysed using Wilcoxon signed rank test; the weight percentage of calcium, phosphorus and fluoride, and the expressions of MMP-2, MMP-8, MMP-9, collagen type I and BSP were compared using paired t test; the restorations characteristics after 10-13 follow-up period were analysed using McNemar test; the mean gray levels over time were compared using two way ANOVA (α= 0.05). Sixty days after cavity sealing, the infected dentin samples exhibited lower values of fluorescence (p<0.0001) and total viable counts (p<0.0001), as well as higher values of consistency (p<0.0001), calcium (p=0.001) and phosphorus content (p=0.002) and expressions of MMP-8 (p=0.018), type I collagen (p=0.004) and BSP (p<0.001). There were no statistical differences in dentin color, fluoride content and expressions of MMP-2 and MMP-9. Ultra-structural changes were clear: the infected dentin showed much less bacteria and better tissue organization, with narrower dentinal tubules and a more mineralized and compact intertubular dentin. After 10-13 months follow-up, the restorations were acceptable clinically, with alterations detected only for cavosurface discoloration (p=0.008), wear (p < 0.001) and surface texture (p < 0.001). The radiographic subtraction routine showed that the mean of gray levels in sound and carious dentin increased (p<0.001). It is possible to conclude that sealing infected dentin from deciduous teeth promotes tissue reorganization and favors the remineralization of remained carious dentin, in a constant process over the time.

Avaliar as variações de densidade óptica da dentina de molares decíduos com lesão de cárie profunda (oclusal), submetidos ao Tratamento Restaurador Atraumático, após três e seis meses. Método: Foram analisadas radiografias interproximais padronizadas digitalizadas de 20 pacientes (42 dentes) com idade entre 4 a 9 anos, para determinar quantitativamente os tons de cinza da região de dentina afetada logo abaixo da restauração em ionômero de vidro, tendo como controle a dentina hígida. Para tal foi utilizado o programa Adobe Photoshop® por meio da ferramenta histograma. A análise estatística da densidade óptica foi feita de acordo com o modelo de efeitos mistos. Resultados: Os valores médios da região de dentina afetada são inferiores aos valores médios da região de dentina hígida, ao longo de todo tempo de acompanhamento. Observou-se que entre os tempos 0 e 3 meses a dentina afetada teve uma variação de 80,99 ± 3,17 a 98,57 ± 3,17, ou seja, um aumento estimado de 18 níveis de tons de cinza (p < 0,0001). Enquanto que a dentina hígida variou de 118,22 ± 3,17 a 122,02 ± 3,17, ou seja, teve um aumento médio de 4 níveis de tons de cinza (p = 0,0003). Já no período entre 3 e 6 meses tanto a região de dentina afetada quanto de dentina hígida tiveram comportamentos semelhantes (98,57 ± 3,17 a 103,32 ± 3,20 e 122,02 ± 3,7 a 126,56 ± 3,20, respectivamente) com aumento de 5 níveis de tons de cinza (p = 0,0001), aproximadamente. Conclusões: De acordo com os resultados desse estudo, pode-se verificar o aumento significativo da densidade óptica da região de dentina afetada após 3 meses, quando comparada à região de dentina hígida em molares decíduos cariados, tratados com a técnica ART. Verificou-se que uma intervenção na dentina afetada estimula todo o complexo dentina-polpa e resulta em conseqüências para toda a estrutura dentinária e pulpar. Sugere-se que o Tratamento Restaurador Atraumático estimulou a remineralização dentinária, de maneira expressiva nos três primeiros meses. Portanto, o Tratamento Restaurador Atraumático é uma técnica indicada para o tratamento restaurador de lesões cariosas em dentes decíduos. _________________________________________________________________________________ ABSTRACT
Evaluate the changes in optical density of the dentin of primary molars with deep caries (occlusal), subjected to Atraumatic Restorative Treatment, after three and six months. Methods: Standardized digitized bitewing radiographs of 20 patients (42 teeth) aged 4-9 years were analyzed, to quantitatively determine the grayscale of the region of the affected dentin beneath the glass ionomer restoration in taking control as the sound dentin. The program Adobe Photoshop ® with the tool histogram was used to measure the graytscale. Statistical analysis of optical density was done according to the mixedeffect model. Results: The average values of the region of the affected dentin are lower than the average values of the region of sound dentin, along the entire length of follow-up. It was observed that the times between 0 and 3 months the affected dentin had a variation of 80.99 ± 3.17 to 98.57 ± 3.17, i.e. an estimated increase of 18 levels of gray tones (p < 0.0001). While the sound dentin ranged from 118.22 ± 3.17 to 122.02 ± 3.17, i.e. had an average increase of four levels of gray tones (p = 0.0003). In the period between 3 and 6 months both the region of dentin as affected dentin had similar behavior (98.57 ± 3.17 to 103.32 ± 3.20 and 122.02 ± 3.7 to 126.56 ± 3.20, respectively) with an increase of approximately five levels of gray tones (p = 0.0001). Conclusion: According to the results of this study, it can be seen significantly increase of the optical density of the region affected dentin after three months, compared to the region of dentin caries in primary molars treated with the ART. It was found that an intervention in the affected dentin stimulates the dentin-pulp complex and results in consequences to the entire structure of dentin and pulp. It is suggested that the Atraumatic Restorative Treatment stimulated dentin remineralization, in the first three months. Therefore, the Atraumatic Restorative Treatment is a technique suitable for restorative treatment of caries in primary teeth.

Introdução: O tratamento de lesões de cárie profundas em dentes decíduos vitalizados e assintomáticos é desafiador e frequentemente está associado a complicações imediatas ou a longo prazo devido ao risco de complicações pulpares. Assim, a remoção seletiva de tecido cariado tem sido considerada a alternativa mais adequada para o tratamento desses casos. Objetivo: Comparar os resultados imediatos da remoção seletiva de tecido cariado em lesões profundas de molares decíduos usando protocolo subjetivo (instrumentos manuais) e objetivo (brocas de polímero). Métodos: 115 crianças de 7-8 anos de idade que apresentavam lesões cariosas com extensão radiográfica além da metade interna da dentina em dentes assintomáticos e com polpas vitais, foram randomizadas em protocolo S (subjetivo) ou O (objetivo). 177 dentes (S, n = 91 e O, n = 86) foram tratados por dois dentistas treinados. A remoção seletiva de dentina cariada foi realizada com instrumentos manuais (S) ou com broca broca de polímero (O, PolyBur, Komet). Todas as cavidades foram restauradas com ionômero de vidro de alta viscosidade (Equia Forte, GC, Tóquio, Japão). Foram registrados dados imediatos pós-tratamento: exposições pulpares, necessidade de anestesia local, tempo de tratamento, satisfação dos pacientes (escala de faces Likert de 5 pontos). Modelos lineares generalizados foram utilizados para a análise estatística. Resultados: não houve exposição pulpar. Apenas duas restaurações necessitaram de anestesia. Os tempos de tratamento [Média (95% CI), S: 432,95s (404,02-461,87) e O: 411,63 (382,50-440,76)] não foram significativamente diferentes entre os protocolos (p = 0,378). A satisfação dos pacientes pós-tratamento foi alta (pontuação mediana 1: muito satisfeito) para ambos os protocolos de remoção seletiva de tecido cariado, sem diferença estatisticamente significativa entre eles (p = 0,164). Conclusões: No que diz respeito à ocorrência de exposições pulpares, à necessidade de anestesia local, ao tempo de tratamento e à satisfação pós-tratamento imediato dos pacientes, não há diferenças estatisticamente significativas entre remoção seletiva de dentina cariada com instrumentos manuais e com brocas de polímero. A longevidade das restaurações e as possíveis complicações serão analisadas nos períodos de acompanhamento do RCT.
Background: The treatment of deep carious lesions in vitalized and asymptomatic deciduous teeth is challenging and frequently associated with immediate or delayed complications because of the risk of pulp exposure. Therefore, a selective removal of carious tissue may be considered an appropriate form of treatment in these cases. Objective: To compare immediate outcomes of selective caries removal of deep lesions in primary molars using subjective (hand instruments) and objective (polymer burs) protocols. Methods: 115 7-8 year-old children presenting radiographically inner-half dentin carious lesions in teeth with vital pulps were randomized into groups S (subjective) or O (objective). 177 teeth (S, n=91 and O, n=86) were treated by two trained dentists. Carious dentin selective removal was performed using hand instruments (S) or a self-limiting polymer bur (O, PolyBur, Komet). All cavities were restored with a high-viscosity glass-ionomer (Equia Forte, GC, Tokyo, Japan). Immediate post-treatment data: pulpal exposures, need of local anesthesia, treatment time, patients' satisfaction (5-points Likert faces scale) were recorded. Generalized linear models were used for statistical analysis. Results: No pulpal exposures occurred. Only two restoration required anesthesia. Treatment times [Mean (95%CI), S: 432.95s (404.02-461.87) and O: 411.63s (382.50-440.76)] were not significantly different between protocols (p=0.378). Post-treatment patients' satisfaction was high (median score 1: very satisfied) for both selective carious tissue removal protocols, with no significant difference between them (p=0.164). Conclusions: Concerning occurrence of pulpal exposures, need of local anesthesia, treatment time, and patients' immediate post-treatment satisfaction, there are no significant differences between hand excavation and polymer burs for selective carious tissue removal. Restorations longevity and possible complications will be analyzed at the RCT follow-ups.

Introdução: A lesão cavitada por cárie, quando não tratada, pode ser considerada como fator etiológico da má oclusão. No Brasil, têm ocorrido melhoras constantes dos índices de saúde bucal, como observado pela diminuição do índice ceo-d, principalmente em crianças e adolescentes. Entretanto, lesões cavitadas em dentina ainda são responsáveis por 80% do índice no grupo etário de 5 anos de idade, indicando baixo acesso de pré escolares ao tratamento restaurador. O surgimento de tratamentos minimamente invasivos, como o Tratamento Restaurador Atraumático (ART), e o tratamento ultraconservador (UCT) possibilitam assistência odontológica em locais remotos ou com baixa estrutura física. Entretanto, pouco se sabe a respeito do impacto destas alternativas de tratamento, quando realizadas em dentes decíduos, sobre o desenvolvimento da oclusão. Objetivos: a) avaliar a prevalência de má oclusão em escolares de 6 e 7 anos de idade que apresentavam lesões de cárie cavitadas em dentina envolvendo ou não superfícies proximais e também em crianças que apresentavam perda precoce de molar decíduo em decorrência de lesão cariosa; b) comparar as medidas intra-arcos e entrearcos nas três diferentes relações anteroposteriores, Classe I, II e III; c) comparar as medidas intra-arcos e entrearcos em escolares com ou sem lesão de cárie cavitada em dentina nas superfícies proximais ou com perda prematura do molar decíduo; d) avaliar longitudinalmente, se diferentes protocolos restauradores têm influência sobre o desenvolvimento da oclusão. Metodologia: Um ensaio clínico controlado foi realizado em escolares de 6 e 7 anos de idade em seis escolas públicas do Paranoá-DF. Naquele estudo, 302 crianças foram distribuídas em 3 grupos experimentais: amálgama, ART e UCT. Para a presente investigação, modelos de gesso dos arcos superiores e inferiores obtidos de 274 escolares imediatamente após a implementação dos protocolos restauradores foram avaliados (T1), com o objetivo de se determinar a prevalência de má oclusão na população estudada. Para esta análise, as crianças foram agrupadas considerando a presença de lesão cavitada em dentina envolvendo ou não as superfícies proximais e crianças que apresentavam perda precoce de molar decíduo. Novos modelos foram obtidos 2 anos após os tratamentos restauradores (T2). Foram comparadas medidas intra-arcos e entrearcos do T1 e T2 por meio de ANOVAs de medidas repetidas.Resultados: A prevalência de má oclusão em escolares com cárie em T1 foi de 74,5%. O principal fator que contribuiu para a alta prevalência de má oclusão foi a relação anteroposterior de Classe II, e os pacientes com essa relação apresentaram diferença estatisticamente significativa dos demais grupos na sobressaliência (P<0,001) e no comprimento do arco anterior (P<0,001) e na distância intercanina (P=0,002), ambas do arco superior. A sobressaliência foi maior, enquanto a distância intercanina e comprimento do arco anterior foram menores. Quando os escolares foram agrupados pela localização e consequência da lesão de cárie, os grupos com ou sem lesão cavitada nas superfícies proximais não apresentaram diferença estatisticamente significativa das medidas intraarcose entrearcos. No entanto, os escolares com perda prematura do molar decíduo apresentaram o menor perímetro do arco inferior (P=0,002). No que se refere à comparação entre T1 e T2, os escolares tratados pelos três protocolos de tratamento restaurador não apresentaram diferença estatisticamente significativa nas medidas intraarcos, tão pouco nas relações entrearcos ao longo dos 2 anos anos de acompanhamento. Conclusão: Conclui-se que a prevalência de má oclusão foi alta e que a relação anterposterior de Classe II esteve associada com menor distância intercanina superior, menor comprimento de arco anterior superior e maior sobressaliência. Os escolares com perda prematura do molar decíduo tiveram o menor perímetro do arco inferior. As distintas abordagens de tratamento da cárie não alteraram o desenvolvimento da oclusão. ______________________________________________________________________________________________ ABSTRACT
Introduction: Untreated tooth decay can be considered an etiological factor ofmalocclusion. In Brazil there has been constant improvement in oral health indices asdetermined by a reduction in the Decayed, Missing and Filled Teeth (DMFT) Index.However, cavitated lesions in dentine are still responsible for 80% of this index in the 5-year-old age group, indicating that pre-school children do not have adequate access torestorative treatment. The emergence of minimally invasive treatments, such asAtraumatic Restorative Treatment (ART), and Ultraconservative Treatment (UCT) providedental care in remote or underserved locations. Moreover, little is known about the impactof these alternative treatments on occlusion when they are performed in primary teeth.Objectives: a) To assess the prevalence of malocclusion in schoolchildren aged 6 and 7years who presented with cavitated lesions in dentine with or without involvement ofproximal surfaces, as well as children who suffered premature loss of primary molars dueto carious lesions; b) To compare the intraarch and interarch measures in three differentanteroposterior relationships, i.e., Classes I, II and III; c) To compare the intraarch andinterarch measures in schoolchildren who presented with cavitated lesions in dentine withor without involvement of proximal surfaces, or premature loss of primary molars; andfinally, d) To assess longitudinally whether or not different restorative protocols can affectocclusion development. Methods: A controlled clinical trial was conducted amongstudents aged 6 and 7 years in six public schools of Paranoá, Brazilian Federal District. Inthe study, 302 children were divided into 3 experimental groups: Amalgam, ART and UCT.For this investigation, dental casts of the upper and lower arches obtained from 274 schoolchildren immediately after implementation of restorative protocols were evaluated (T1) withthe purpose of determining the prevalence of malocclusion in this population. The childrenwere grouped based on the presence of cavitated lesions in dentine with or withoutinvolvement of proximal surfaces as well as premature loss of primary molars. New castswere obtained 2 years after the restorative treatment (T2). Moreover, intraarch andinterarch measures at T1 and T2 were conducted by means of ANOVA for repeatedmeasures. Results: The prevalence of malocclusion in children with caries at T1 was74.5%. The key factor contributing to a high prevalence of malocclusion was ananteroposterior Class II relationship. The patients with this relationship exhibitedstatistically significant differences compared to the other groups in terms of overjet(P<0.001) and anterior arch length (P <0.001) and intercanine width, all in the upper arch(P =0.002). Overjet was more pronounced while intercanine width was smaller andanterior arch length shorter. When the school children were grouped by location andeffects of carious lesions, the groups - with or without cavitations in proximal surfaces -showed no significant difference in intraarch and interarch measures. Nevertheless,students with premature loss of primary molars exhibited the smallest mandibular archperimeter (P = 0.002). As regards the comparison between T1 and T2, the school childrenwho were treated by the three restorative treatment protocols showed no statisticallysignificant differences in intraarch or interarch measures over a 2-year follow-up period.Conclusions: It was concluded that the prevalence of malocclusion was high and that ananteroposterior Class II relationship was associated with a smaller maxillary intercaninewidth, shorter maxillary anterior arch length and increased overjet. School children withpremature loss of primary molars displayed the smallest mandibular arch perimeter. The different approaches employed with the aim of treating caries had no effect on occlusion development.

Full textThe aim of this study was to evaluate the microleakage in class II glass ionomer cement restorations in primary molars. For this, were selected fourty primary molars in a human teeth bank. At mesial and distal surfaces of the teeth were prepared standard class II cavities. In sequence, the teeth were subdivided in eight experimental groups in according with the restorative material used: group MXR (Maxxion R); group VDR (Vidrion R); group VTR (Vitremer); group VTF (Vitro Fill LC); group FUJ (Fuji IX); group KTM (Ketac Molar); group VMO (Vitro Molar); group MGS (Magic Glass ART). After past twently four hours in immersing water, the restored teeth were immersed in a 50% solution of silver nitrate for similar period, and, then, in radiographic solution (hydroquinone, Kodak) for fiteen minutes. The teeth were sectioned at the center of restorations, and observed at stereoscope under forty-fold increase. The microleakage was graduated in scores related with the grade of silver nitrate penetration at the adhesive interface. The results, after submitted statistical analysis, showed that none of the materials impeded completely the microleakage. Thus, Vitremer showed the minor scores, followed by Ketac Molar and Fuji IX. The materials, Magic Glass ART, Vitro Molar, Vitro Fill LC and Vidrion R showed intermediary results, while Maxxion R showed the worse ones. Based in methodology used in this study and in their results, its possible concluded that none of the materials was able to impede the microleakage, although presented variable grades susceptibility of this phenomenom, with emphasis to Vitremer, Ketac Molar and Fuji IX because presented minor microleakage, following Magic Glass ART, Vitro Molar, Vitro Fill LC and Vidrion R. On the other hand, Maxxion R presented the worse results, fact confirmed by high microleakage scores observed.

Full textThe atraumatic restorative treatment is an approach of minimally invasive care that aims to prevent and interrupt the progression of dental caries. There is no randomized clinical trial in primary teeth with multiple surface ART restorations, with and without additional retentions. The aim of this study was to evaluate the effect of proximal retention grooves on the survival rates of occlusoproximal ART restorations in primary teeth using high viscosity glass ionomer cement with high flexural strength. A total of 183 children aged 4 to 7 years, with good general health, 1 to 4 occlusoproximal cavities in primary molars without pulp involvement or tooth pain were included. Of these children, three hundred teeth were randomized and alocated into two groups, according to the child\'s caries index and the size of the cavity to be restored. The groups were: control - conventional occlusoproximal ART restorations (Group 1, n=150) and test - occlusoproximal ART restorations containing proximal retention grooves (Group 2, n=150). The procedures of both groups followed standardized steps. In the test group the retentions were performed with a modified dentin spoon at the gingival-vestibular / lingual angle up to 0.5 mm from the amelodentin junction of the occlusal margin. After 6 and 12 months 130 restorations in Group 1 and 110 restorations in Group 2 were examined (blind) using the modified ART Frencken criteria and the modified USPHS criteria. The Kaplan-Meier test was performed for the survival rate of the restorations (p<0.05). There was no significant difference between groups (p=0.70) using the ART criteria, and the survival rates found for both groups were greater than 90%. The same results was observed for all USPHS criteria (color, marginal discoloration, secondary decay, anatomical form, marginal integrity and surface texture) (p>0.05). The main reasons for restorations failure were total or partial loss of restoration (84%), followed by pulpal inflammation (16%). It was concluded that multiple surface ART restorations with proximal retention grooves presented similar survival rates to non-grooves restorations after 6 and 12 months.

O objetivo do presente estudo foi realizar uma revisão sistemática e meta-análise (MA) sobre o desempenho clínico do cimento de ionômero de vidro (CIV) comparado ao de resina composta (RC) em restaurações classe II em dentes decíduos. Foi realizada uma busca abrangente nas bases PubMeb, Scopus, Web of Science, LILACS-BBO, Cochrane Library, Clinical Trials e OpenGrey, sem restrições de data ou idioma. Foram utilizados termos Mesh, sinônimos e palavras chave, adaptados para cada base de dados. Também foi feita busca manual na lista de referências dos artigos selecionados. Foram incluídos 5 ensaios clínicos controlados e randomizados e 3 estudos clínicos não randomizados, que compararam o desempenho clínico, avaliado pela presença de lesões de cárie secundária, descoloração marginal, adaptação marginal, forma anatômica e retenção e desgaste do material restaurador de restaurações de classe II realizadas com CIV em comparação com restaurações de RC em dentes decíduos. Quinze estudos completos foram lidos na íntegra, dos quais 8 foram incluídos na síntese qualitativa (risco de viés) e quantitativa (meta-análise). A heterogeneidade variou de baixa a moderada nas 12 MAs realizadas dos 8 estudos, com acompanhamento de 6 a 48 meses (38 a 73%), não havendo diferença significativa entre os dois materiais na análise final (overall effect). A diferença de risco (intervalo de confiança 95%; valor de p) entre RC e CIV quanto a falhas foi de -0,03 (-0,11 – 0,05; p= 0,41); quanto a adaptação marginal, -0, 01 (-0,06 – 0,05; p= 0.8); quanto a descoloração marginal, 0,07 (-0,11 – 0, 26; p=0,44), quanto a forma anatômica, 0,00 (-0,04 – 0,05; p= 0,84); e quanto a presença de lesão de cárie secundária foi de 0,07 (0,02 – 0,12; p= 0,01). A diferença de risco geral para o desempenho clínico foi 0,03 (-0,01 – 0,06; p= 0,17). Para todos os parâmetros analisados, a exclusão de um estudo com menos de 24 meses de acompanhamento e dos estudos não randomizados não influenciou no resultado final da MA. Entretanto, os resultados foram significativamente influenciados pelo tipo de CIV (convencional (n=2) ou modificado por resina (n= 6) e tipo de isolamento (absoluto (n=6) ou relativo (n=2)). Concluiu-se que o CIV modificado por resina apresentou desempenho clínico significativamente superior a RC em relação à prevalência de lesões de cárie secundária, enquanto que o CIV convencional se mostrou semelhante à RC para este parâmetro. Quanto à porcentagem de falhas, adaptação marginal, descoloração marginal e forma anatômica, ambos os materiais apresentaram desempenho semelhante, independente do tipo de CIV. Assim, a possibilidade de fotopolimerização, somada às suas propriedades cariostáticas, indicam que o CIV modificado por resina é o material de escolha para restaurações classe II em dentes decíduos.

O objetivo deste estudo in vitro foi analisar, ao microscópio de luz polarizada, os aspectos histológicos do esmalte decíduo, empregando-se diferentes modelos de indução de formação de lesão artificial de cárie. Avaliou-se também a influência de dois materiais restauradores na formação da lesão de cárie secundária quando submetidos aos mesmos modelos. Foram selecionados vinte dentes apresentando lesão natural de mancha branca de cárie (grupo controle) e quarenta dentes clinicamente hígidos, divididos em dois grupos conforme o modelo de indução de formação de lesão de cárie. Após este período, os espécimes foram incluídos em resina e seccionados longitudinalmente obtendo-se secções de 100æm de espessura, que foram embebidas em água destilada ou quinolina para análise ao microscópio de luz polarizada. Os resultados obtidos na primeira parte do estudo revelaram a formação das quatro zonas histológicas da lesão de mancha branca nos dois modelos empregados, porém morfologicamente distintas. Na segunda parte, os valores de profundidade da lesão externa, obtidos por meio de análise histomorfométrica, foram submetidos ao teste estatístico de análise de variância (ANOVA) constatando-se que o grupo do cimento de ionômero de vidro exibiu profundidade da lesão externa significantemente menor do que o grupo restaurado com resina composta, independentemente do modelo de indução. As amostras do G4 apresentaram maior ocorrência de zonas de inibição do que as do G5. Concluiu-se que os modelos de indução foram eficientes na formação da lesão artificial de cárie, e que independentemente do modelo o CIV foi mais eficiente na inibição da formação de lesões de cárie.
The aim of this in vitro study was to compare by polarized light microscopy the histopathological appearance of caries-like lesions of enamel created artificially in primary teeth based on different models. Methods: 60 deciduous human molars were used. In G1 (n=20): control group, the specimens with natural white spot lesions, examined in incident light, were stored in deionized water for 14 days. After this, longitudinal ground sections were taken from all groups and examined while immersed in water or quinoline using polarized light microscopy techniques. Buccal class V restorations were prepared in 40 deciduous human molars with margins in enamel that were randomly divided into two groups (n=10) using a hybrid resin composite (Z-250) and a conventional glass ionomer cement (Fuji IX GP Fast). After the restorative procedures, all teeth surfaces were coated with nail polish, except for the restoration area and 1mm rim of tooth structure. In order to induce artificial carious lesions, the specimens were immersed into the models. After this, the specimens were prepared for polarized light microscopy in an imbibition's media of water. The results showed the development of caries lesions in all groups Areas of positive birefringence were seen in the subsurface enamel with negatively birefringence surface zone. The data was analyzed by ANOVA test (5%) and the specimens restored with glass ionomer cement exhibited the depth of caries significantly lower than the group restored with composite resin. It was concluded that the restorative material could influence the demineralization of primary enamel.

Abstract: The aim of the present study was to perform a systematic review and meta - analysis (MA) on the clinical performance of glass ionomer cement (GIC) compared to composite resin (CR) in class II restorations in deciduous teeth. A comprehensive search was performed on the PubMeb, Scopus, Web of Science, LILACS - BBO, Cochrane Library, Clinical Trials and OpenGrey databases, without dat e or language restrictions. Mesh terms, synonyms and key words were used, adapted for each database. Manual search was also performed on the list of references of the selected articles. Five randomized controlled trials and three non - randomized clinical tr ials comparing the clinical performance (assessed by the presence of secondary caries lesions, marginal discoloration, marginal adaptation, anatomical shape, and retention and wear of restorative material) were included in class restorations II performed w ith GIC compared to RC restorations in deciduous teeth. Fifteen complete studies were read in full, of which 8 were included in qualitative (risk of bias) and quantitative synthesis (meta - analysis). The heterogeneity ranged from low to moderate in the 12 M As from the 8 studies, with a follow - up of 6 to 48 months (38 to 73%), with no significant difference between the two materials in the final analysis (overall effect). The risk difference (95% confidence interval, p value) between RC and GIC for failure wa s - 0.03 ( - 0.11 - 0.05; p = 0.41); for marginal adaptation was - 0.01 ( - 0.06 - 0.05; p = 0.8); for marginal discoloration it was 0.07 ( - 0.11 - 0.26, p = 0.44), and for the anatomical form it was 0.00 ( - 0.04 - 0.05; p = 0.84).

Full textThe aim of this study was to evaluate if the new nanoparticulate material, the glass carbomer can increase the survival rate of occlusal-proximal-ART restorations compared with compomer - a polyacid resin modified material and a high viscosity glass ionomer cement (GIC). A total of 286 children aged 5 to 7 years presenting at least one occlusal-proximal carious lesion were selected in the city of Barueri, SP. Patients were randomized into three groups: high viscosity GIC (GIC - Fuji IX Extra - GC Corp), Compomer (COM - Dyract Extra - Dentsply) and Glass Carbomer (CAR - Glass Carbomer - GCP Dental). All treatments were made following the precepts of ART and manufacturers\' recommendations. The restorations were evaluated after 2, 6 and 12 months by a trained examiner. To verify the survival of the restorations was used Kaplan-Meier survival analysis and log-rank test. To evaluate the association between the outcome and patient variables was applied Cox regression test. The significance level for the tests was 5%. After 12 months of follow-up, overall survival rate of the restorations was 52.8%. The GIC, COM and CAR survival rate were 62.6%, 61.3% and 36.3%, respectively. Statistical analysis showed significant differences between the materials, where the CAR had a worse performance (HR = 1.84, CI 1.19 to 2.85; p = 0.006) and no difference was found between the CIV and COM materials. Moreover, statistical differences were found for the variable volume of the cavity, where smaller cavities had higher chances of failure (p <0.03). We conclude that the new glass carbomer material is not suitable for use in ART occlusal-proximal restorations in primary molars compared to high viscosity GIC and the compomer.

Full textThe purpose of this study was to evaluate for two years the clinical performance of a resin-modified glass ionomer cement (Vitremer - 3M) and the condensable composite resin (Solitaire - Kulzer) in the restoration of class II cavities in primary teeth. Clinical, radiographic, direct following exfoliation in the primary molars and marginal microleakage evaluations were performed. A total of 64 class II cavities in the primary molar was restored with resin modified glass ionomer cement (Vitremer - 3M) and 59 class II cavities in the primary molars with condensable composite resin (Solitaire - Kulzer). The preparation was accomplished according to the extension of the decay process. The dentist placed resinmodified glass ionomer cement according to the manufacturers recommendations. First, he placed a dentin primer and light-polymerized it. Then, he hand-mixed the fluoroaluminosilicate glass powder base with the poliacrilic acid, placed it in the cavity preparation (Centrix) and then exposed it to visible light for initial polymerization. The composite resin Solitaire was placed in the cavity preparation in increments. Each restoration was directly and clinically evaluated at baseline and at 6, 12, 18, 24 months, based on the modified United Stated Public Health Service methodological technique for evaluations. Standardized bitewing radiograph were accomplished in the baseline and at 24 months. After exfoliation, the teeth were stored in distilled water with timol 1% with purpose of inhibiting the bacterial growth. Visual inspection was carried out in the thirty-six restorations collected after exfoliation, to evaluated recurrent decay and marginal microleakage. The roots were sealed with composite resin Z 100 (3M) and applied two layers of fingernail enamel at 1mm of the margins of the restorations, being the specimens immersed in basic fucsin solution, at 0,5%, at a temperature of 37oC, for 24 hours, and rinsed in running average water for 24 hours, sectioned and evaluated. Each sample was included in auto-cured resin and mesiodistal planes, with a diamond disk had three cuts. Decay size, the indirect analysis of the size restorations and the marginal microleakage in the cervical wall, were measured in a computer program (Sigma Scan). Mann-Whitneys test was used for the analysis among the materials, and for the analysis in the same restorative material, although in different observation periods; of Wilcoxon paired test used. As to the analysis of measures accomplished in the decay of the teeth after exfoliation and marginal microleakage, the t test was used. The significance level of 5% was used in all tests. The clinical results demonstrated, after 24 months of evaluation, that Vitremer presented better results when compared with Solitaire, begin: the marginal discoloration, 89,00% and 33,89%; anatomic form, 56,25% and 11,86%; marginal integrity, 46,87% and 15,25%; maintenance of interproximal contact, 92,18% and 69,49%; except for color stability, 79,68% and 80,35%; and surface texture, 37,50% and 81,35% Solitaire presented better results, being these resulted related to percentages of the score Alpha, in the evaluation of 24 months. This study verified that there is not a direct, general influence when removing the pulpal roof chamber for the pulpal therapy, on the clinical behavior of, restoring materials. Only in some evaluation requirements, as marginal discoloration, surface texture and maintenance of interproximal contact is that the teeth that suffered pulpal therapy presented a little inferior performance, being practically equal in most instances, or even superior, in the case of color stability, in relation to Vitremer. The clinical performance was evaluated through bitewing radiographs, regarding the conformity of the restoration with the tooth in relation to the proximal contour, a similarity among groups, not presenting statistical differences, because Vitremer showed medium score at 24 months of 1,08 and Solitaire 1,29. As to the presence of a radio-lucid area in the gingival wall, the results were statistically significant and Solitaire presented a larger number of teeth with radio-lucid areas in the enamel and dentin, in relation to Vitremer, in the evaluation of 24 months, with an average score of 0,17 and 1,23, respectively. When analyzing the clinical performance in relation to the size of the restoration and the tooth in which localized, a conformity is verified in the results, where the size of the restoration tends to not influence the result of the material. The quantitative and qualitative caries recurrence evaluation in the teeth, after exfoliation, was greater the proximal surface of the composite resin, presenting a larger number of carious lesions, being this number statistically significant, since the average of Solitarie was 3,82mm2 and that of Vitremer 0,11mm2 of recurrent caries. In the oclusal surface, there was a significant statistically difference among the tested materials, being the average of Solitaire 1,25 mm2 of recurrent caries and Vitremer did not present recurrent caries in the oclusal surface. When analyzing the marginal microleakage in the teeth, after exfoliation through the use of dye, a larger penetration of the it was verified in the gingival wall in the teeth restored with composite resin, presenting 1,73 mm in average in the penetration of the dye and 0,35mm in average, for Vitremer, being the differences statistically significant. In the evaluations accomplished in this study, it was verified that the resin-modified glass ionomer cement (Vitremer) presented a favorable clinical and radiographic performance, and smaller marginal microleakage in class II restorations in primary molars, in the assessed period, surpassing the performance of the "condensable" composite resin (Solitaire).

The objective of the present study was to analyze the interaction between a ionomeric material and dentinal tissue using two cavity preparation techniques and different surface treatments. For this purpose, 40 deciduous teeth (n = 10). Cavity preparation was performed with rotary cutting instruments by the standard technique or by the technique employed in atraumatic restorative treatment (ART) using manual cutting instruments. For conditioning of the dentinal surface 37% phosphoric acid and 12.5% polyacrylic acid were used. Restoration of the specimens was performed with Fuji II LC resin-modified glass ionomer cement, and the groups were submitted to the following treatments: (1) dentinal curettes + phosphoric acid + Fuji II LC; (2) burs + phosphoric acid + Fuji II LC; (3) dentinal curettes + polyacrylic acid + Fuji II LC; (4) burs + polyacrylic acid + Fuji II LC. After decalcification and paraffin embedding, the specimens were sectioned, mounted sequentially on glass slides, stained by the method of Brown and Brenn, and analyzed under an Axiophot (Zeiss) polarized light microscope. The results were analyzed quantitatively and qualitatively by analysis of variance and by the Tukey test. With respect to the interaction area between the tooth and restorative material, specimens of group 4 showed no formation of tags in dentinal tissue, whereas the other combinations of conditioning agents and techniques led to the formation of tags of similar lengths. Qualitative analysis showed an irregular cavity surface in the two groups treated by the ART technique, in addition to numerous bacterial colonies throughout the extension of the cavities. Formation of an interaction area between dentinal tissue and ionomeric material was observed in all groups, with this interaction being more regular and showing less variation in thickness in group 2.

Full textThe aim of this research was to evaluate the survival rate of occluso-proximal restorations performed by the Atraumatic Restorative Treatment (ART) with two different insertion techniques of the glass ionomer cement (GIC - conventional technique and bilayer technique), and assess the influence of the type of surface protection (petroleum jelly and a nanofilled particles coating for GIC - G-Coat Plus® - GC Corp). Furthermore, we investigated the clinical wear of conventional ART-restorations protected with petroleum jelly and G-Coat Plus®. Occluso-proximal caries lesion in primary molars from 208 schoolchildren were selected and randomly assigned into four groups: group 1, conventional GIC insertion protected with petroleum jelly; G2, bi-layer technique protected with petroleum jelly; G3 conventional GIC insertion protected with G-Coat Plus®; G4, bi-layer technique protected with G-Coat Plus®. The restorations were clinically evaluated after 1, 6, 12, 18, 24 and 36 months. Additionally, 32 children were selected (16 from group 1 and 16 from group 3) to have impressions of the hemi-arc involving the restoration accomplished. The impressions were carried out 1 day after treatment and during the assessment periods of 6, 12, 18, 24 and 36 months. The impressions were taken to the Academic Centre for Dentistry Amsterdam (ACTA), The Netherlands, to have the restorative material wear evaluated in 3D scanner and the obtained images were subtracted in appropriate computer software. Kaplan-Meier survival analysis and log-rank tests were performed to verify the survival rate of restorations. Cox regression analysis was used to verify the influence of clinical factors in the longevity of restorations. Two-way ANOVA and Tukey post-hoc test were used to analyze the wear of the restorations. The significance level for the tests was considered as 5% .The results showed that the overall survival rate of the restorations was 52.8% after 36 months of follow-up and the most prevalent type of failure was fracture / loss of restoration, in that conventional ART-restoration protected with petroleum jelly group presented significantly more prevalence of this type of failure (p<0.05). Survival analysis showed better survival of the two layers technique compared with conventional insertion of GIC (p=0.005), while the conventional restorations protected with G-Coat Plus® showed higher survival rate compared with those protected with petroleum jelly (p=0.035). Cox regression analysis showed no influence of any variable tested on the longevity of restorations. Regarding the clinical wear, there was a significant difference between the coated and uncoated restorations when the selected area of 1mm2 of the restoration was investigated (p<0.05), with a clear wear protection offered by the application of nanofilled resin coat; however when investigating the hemi-arch of patients, there were no significant differences between the two materials (p>0.05). We can conclude that the survival rate of the approximal ART-restorations in primary teeth was positively influenced by the bi-layer technique. Furthermore, the application of a nanofilled particles coating for GIC increased the longevity and decreased the wear of conventional ART-restorations in primary teeth when compared to petroleum jelly.

Full textIntrodução: A manutenção da dentição decídua é importante para o bem-estar geral da criança. A cárie dentária, as pigmentações, os traumatismos, a perda precoce de dentes, os maus posicionamentos dentários ou qualquer outra anomalia de forma e tamanho dos dentes, podem contribuir para uma estética insatisfatória. Os problemas estéticos em odontopediatria podem ser solucionados de diferentes formas. Uma restauração anterior ideal em dentição decídua deverá ser de fácil colocação, duradoura, estética, pouco dispendiosa, retentiva e resistente. As opções terapêuticas estéticas podem ser subdivididas em: restaurações intracoronárias (resinas compostas e ionómeros de vidro modificados COM resina) e restaurações coronárias totais (coroas de acetato, coroas de policarbonato, coroas metálicas de face aberta, coroas metálicas com faceta em resina e coroas de zircónia). Objetivos: Identificar e comparar as principais restaurações estéticas e funcionais em dentes anteriores decíduos. Materiais e métodos: Pesquisa de artigos científicos na base de dados eletrónica PubMed-Medline desde agosto de 2016. Foram considerados artigos escritos na língua portuguesa ou inglesa, estudos realizados apenas em humanos, e publicados desde o ano de 2007. Obtiveram-se 102 artigos, dos quais foram selecionados 16 com base na leitura do título e do abstract. Esta pesquisa foi posteriormente complementada com a consulta da bibliografia de artigos relevantes. Conclusão: Devido à falta de suporte cientifico documentado, nenhuma destas opções estéticas e funcionais pode ser considerada superior a todas as outras. A seleção do material a utilizar dependerá de cada clínico e tem por base a informação que existe, mas, principalmente a prática clínica e as circunstâncias clínicas que cada clínico experiencia. É importante que se selecionem restaurações que sejam bem aceites pelos pais e pelas crianças e que assegurem a estética e a função dos dentes decíduos.
Introduction: Maintenance of the primary dentition in a nonpathologic and healthy condition is important for the overall well-being of the child. Dental caries, pigmentation, trauma, early loss of teeth, poor dental positioning or any other anomaly in the shape and size of the teeth can contribute to an unsatisfactory aesthetic. These aesthetic problems in pediatric dentistry can be solved in different ways. An ideal anterior restoration should be easy to place, durable, esthetically pleasing, inexpensive, retentive and strong, since it is necessary to last until exfoliation of deciduous teeth. Aesthetic therapeutic options can be subdivided into: intracoronal restorations (composites and resin-modified glass ionomers) and full-coronal restorations (composite strip crowns, polycarbonate crowns, open face SSC, pre-veneered SSC and zirconia crowns). Objectives: To identify and compare the main aesthetic and functional restorations in deciduous anterior teeth. Materials and methods: A research of scientific articles in the PubMed-Medline electronic database since August 2016. The filters used were, written in portuguese or english, only based in human studies and published since the year of 2007. From 102 articles obtained, 16 were selected based on the reading of the title and the abstract. This research was later complemented by other relevant articles. Conclusion: Due to the lack of scientific support, none of these aesthetic and functional options can be considered superior to all others. The selection of the material to be used will depend on each clinician and is based on the information that exists, but mainly the clinical practice and the clinical circumstances that each clinician experiences. It is important to select restorations that are well accepted by parents and children and that ensure the aesthetics and function of deciduous teeth.

Full textIntrodução: O sucesso clínico das restaurações depende, determinantemente, do sistema adesivo utilizado. A existência de vários sistemas adesivos, com diferenças na sua composição, apresentação, protocolo clínico e eficácia tornam a escolha complexa. Usualmente, os tratamentos restauradores para dentes decíduos eram uma extensão dos aplicados em dentes definitivos. Contudo, a constatação das especificidades caraterísticas dos dentes decíduos evidenciou a necessidade de desenvolver estratégias restauradoras mais adequadas a estes dentes. Objectivos: Este trabalho objetivou avaliar a eficácia clínica a 6 meses (6M) e 12 meses (12M) de 3 sistemas adesivos (um etch-and-rinse de 2 passos, um self-etch de 2 passos e um self-etch de 1 passo) usados em restaurações com resina composta em molares decíduos. Em concomitância realizou-se um estudo laboratorial objectivando avaliar as forças de adesão dos mesmos sistemas adesivos em esmalte decíduo. Analisou-se também in vitro o padrão de condicionamento obtido pelos mesmos sistemas adesivos nos substratos dentários, bem como a ultramorfologia das interfaces produzidas com recurso a microscopia electrónica de varrimento (MEV). Materias e métodos: Foi realizado um estudo clínico randomizado, com 101 restaurações classe II em molares decíduos de 34 crianças (4-8 anos), utilizando 3 sistemas adesivos: GI – ClearfilTMS3Bond (CSE), GII – ClearfilTMSE Protect Bond (CSE PB), e GIII - Prime&Bond® XP (PB XP) e uma resina composta (Ceram.X® Universal). As restaurações foram avaliadas com critérios aprovados pela FDI, de acordo com parâmetros estéticos, funcionais e biológicos, num período inicial (0M), aos 6 e aos 12 meses. Todos os requisitos éticos e legais foram cumpridos. Para o estudo laboratorial, prepararam-se 16 molares, distribuídas aleatoriamente por 3 grupos: G1 – Prime&Bond® XP, GII – ClearfilTMSE Protect Bond, e GIII - ClearfilTMS3 Bond. Após a aplicação dos adesivos no esmalte segundo o protocolo dos fabricantes, foram construídos blocos de resina composta Ceram.X® Universal. As amostras foram seccionadas para obter bastonetes de secção quadrangular (1mm2), e submetidos a ensaios de microtração (0.5 mm/min). As superfícies fraturadas foram examinadas sob microscopia ótica para classificar os padrões de fratura. A análise estatística foi efetuada usando a plataforma estatística IBM® SPSS® v24 e o MS Excel® (nível de significância de 5%). Adicionalmente, foram preparadas amostras para MEV, para avaliação das interfaces adesivas e da micromorfologia superficial produzida Resultados: No que concerne ao ensaio clínico, as propriedades estéticas, biológicas e a maioria das propriedades funcionais avaliadas permaneceram sem alterações estatisticamente significativas ao longo do tempo. Apenas foi possível identificar diferenças estatisticamente significativas, com agravamento dos scores, no critério “adaptação marginal” entre os resultados do tempo inicial e os 12M para os 3 grupos de estudo. Comparando os grupos entre si, apenas foi possível detetar diferenças estatisticamente significativas no critério “fratura do material e retenção da restauração” entre o grupo I e o grupo III (que apresentou piores resultados). No estudo laboratorial para avaliação das forças de adesão ao esmalte decíduo, o PB XP apresentou valores de adesão estatisticamente superiores aos do CSE PB e CSE, que, por sua vez, não foram estatisticamente diferentes entre si. No esmalte o condicionamento com ácido fosfórico, respeitante ao adesivo do tipo etch-and-rinse, produz um padrão de desmineralização e microrugosidade mais profundo, amplo e uniforme que qualquer dos adesivos self-etch. Ao nível da dentina no que concerne à remoção/dissolução da smear layer e smear-plugs, embora os resultados sejam também mais marcantes para o condicionamento com ácido fosfórico, não são muito diferentes do padrão obtido com o primer do CSE PB. Pelo contrário, o padrão superficial dentinário obtido pelo CSE é muito diferente do padrão de condicionamento com ácido fosfórico do adesivo etch-and-rinse PB XP, permanecendo muita da smear layer e dos smear plugs na superfície da dentina instrumentada. Relativamente às imagens de MEV das interfaces adesivas em esmalte decíduo, o sistema adesivo do tipo etch-and-rinse mostrou uma melhor interface ao nível do esmalte, mais regular e sem falhas aparentes, relativamente aos adesivos self-etch. Conclusões: Em relação ao ensaio clínico, relativamente à comparação intergrupos, detetaram-se diferenças significativas entre os sistemas adesivos avaliados apenas no que respeita ao parâmetro referente à “retenção da restauração”. Neste fator, o GIII (PB XP) apresentou resultados significativamente piores aos 12M comparativamente ao GI (CSE). No que respeita às comparações longitudinais intragrupo verificou-se apenas um agravamento significativo dos scores respeitantes ao parâmetro “adaptação marginal” para todos os grupos ao longo do tempo e do parâmetro “retenção da restauração” para o GIII aos 12M. Em relação aos restantes parâmetros das “propriedades funcionais”, às “propriedades biológicas” e às “propriedades estéticas” não se verificaram diferenças significativas ao longo dos períodos de avaliação. No que concerne à avaliação laboratorial das forças de adesão ao esmalte decíduo, o PB XP proporcionou valores estatisticamente mais elevados que os dois sistemas self-etch, que por sua vez não foram significativamente diferentes entre si. No que se refere à avaliação laboratorial por MEV dos padrões de condicionamento superficial obtidos pelos 3 sistemas adesivos, verificaram-se diferenças micromorfológicas quer ao nível da dentina, quer do esmalte.
Introduction: The clinical success of restorations is decisively dependent upon the adhesive system used. Choosing an adhesive system is complex due to the existence of several types with distinctive compositions, forms of presentation, clinical protocols and efficacy. To date, restorative protocols recommended for primary teeth have been a simple extension of those used in definitive teeth. However, evidence on the singularities of primary teeth has emphasized the need to develop more appropriate restorative strategies for primary dentition. Objectives: This study aimed to evaluate the clinical efficacy at 6 months (6M) and 12 months (12M) of 3 adhesive systems (a two-step etch-and-rinse, a two-step self-etch and one step self-etch) used with composite resin restorations in deciduous molars. In parallel, an in vitro study was conducted to assess and compare the microtensile bond strenghts of these adhesives to deciduous enamel. Scanning electron microscopy (SEM) evaluation of the conditioning pattern obtained in enamel and dentin, and ultramorphologic assessment of the enamel adhesives interfaces were also performed. Materials and methods: A randomized clinical study involving 101 class II restorations in deciduous molars of 34 children (4-8 years old) was conducted using 3 adhesive systems: GI - ClearfilTMS3Bond (CSE), GII - ClearfilTMSE Protect Bond (CSE PB), and GIII - Prime&Bond® XP (PB XP) and composite resin (Ceram.X® Universal). Restorations were evaluated according to aesthetic, functional and biological parameters of the FDI approved criteria, immediately after execution (0M) and after 6M and 12M. All ethical and legal requirements were met. The laboratory study entailed the preparation of 16 molars, randomly distributed by 3 groups covering the same aforesaid adhesive systems: GI- Prime&Bond® XP (PB XP), GII- ClearfilTMSE Protect Bond (CSE PB), and GIII- ClearfilTM S3Bond (CSE). After applying the adhesive system on enamel as recommended, Ceram.X® Universal composite blocks were built. Samples were then cross-sectioned into quadrangular test specimens and subjected to microtensile tests. Fracture patterns were classified by optical microscopy examination. Statistical analysis was performed using IBM®SPSS®v24 and MS Excel® (5% significance level). Additional samples were prepared for SEM evaluation of the adhesive/enamel interfaces and superficial enamel and dentin micromorphology produced by the studied adhesive systems. Results: Concerning clinical trial, aesthetic, biological and most of the functional parameters evaluated remained without significant changes over time. Statistically significant differences were only found in the "marginal adaptation" parameter between the 0M and the 12M periods, with worsening of scores for the 3 groups. Among groups, statistically significant differences were only found in the "fracture of the material and retention of restoration" parameter at 12M between group I and III, as the latter presented worse results. In the laboratory study, PB XP showed statistically higher microtensile adhesion values than CSE PB and CSE, which, in turn, did not significantly differ from each other. Ultramorphological differences were found in both enamel and dentin surface patterns obtained by the 3 used adhesive systems. Enamel conditioning with phosphoric acid (etch-and-rinse adhesive type) produced the most deep, wide and uniform demineralization and microroughness pattern. As to the removal/dissolution of the smear layer and smear-plugs in dentin, though phosphoric acid results were more striking, they did not markedly differ from those of CSE PB primer. Contrarily, the dentin surface pattern obtained by CSE differed from the standard conditioning of the etch-and-rinse adhesive, with a lot of smear layer and smear plugs remaining on the instrumented dentin’s surface. Also, SEM evaluation showed a better, more regular and apparently flawless enamel adhesive interface in the etch-and-rinse adhesive group, comparing to both self-etch systems. Conclusions: In the clinical trial significant differences were found between the tested adhesive systems only in relation to the "restoration retention" parameter. In this factor, etch-and-rinse adhesive system type presented significantly worse results at 12M compared to the self-etch adhesive type. As to the intra-group longitudinal comparisons, only a significant worsening of the "marginal adaptation" scores was found for all groups over time and for the "retention of the restoration" parameter for PB XP at 12M. No significant differences were detected in the aesthetic, biological and remaining functional parameters over time. In laboratory evaluation of the adhesion forces, PB XP produced statistically higher values than the self-etch systems, which in turn did not significantly differ from each other. Evaluation by SEM of the surface conditioning patterns obtained by the 3 adhesive systems showed important micromorphological differences at both dentin and enamel levels.
