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.
