Full textAbstract:
Aesthetics is often the main and occasionally the only criteria by which orthodontic treatment is judged. The literature has many references concerning the ideal positions of teeth, however little importance is given to the tooth contacts that eventuate. It is assumed on a number of occasions that settling will provide the best possible fit.
The aim of this thesis is to simulate orthodontic treatment on hypothetical patients and evaluate the tooth contacts which result from this treatment. Stylised tooth contacts have been produced for intact dentitions but in spite of an extensive search of the literature no patterns for extraction cases were found. The experiment, therefore, was to use "normal" teeth in wax malocclusions representing Class I, Class H Div 1, Class II Div 2 and Class III. Where it was indicated these were treated with extractions of premoiar teeth. It was considered that the different mechanics and torque values of the anterior brackets may have dissimilar affects on the resultant occlusions. If this was the case it would be manifest in the resultant tooth contacts. Quantity and site of tooth contact was noted, quality was difficuit to assess as one may move teeth to where one believes they belong but nature will place them where they best adapt to the needs of the stomatognathic system. This obviously could not be considered using an articulator and wax models.

Full textAbstract:
The controversy surrounding the role of malocclusion and orthodontic treatment in temporomandibular joint (TMJ) dysfunction led to this study. The purpose of this study was to establish the prevalence and compare the status of signs and symptoms of TMJ dysfunction in four groups of adolescents and young adults. The groups consisted of 14 persons with normal occlusions, 23 with untreated malocclusions, 20 with malocclusions currently undergoing treatment, and 18 with treated malocclusions. The Helkimo index was used to collect the TMJ dysfunction data. The results showed that the untreated malocclusion group had the most number of persons with signs and symptoms of dysfunction, but the differences between the groups in the distribution of persons according to the anamnestic and clinical dysfunction indices were not statistically significant. There were also no statistically significant differences in the distribution of signs and symptoms between boys and girls. According to anamnesis, the most frequently reported symptoms were joint sounds and headaches or neckaches occurring more than twice a week. Amongst the clinical signs and symptoms, themost commonly occurring were joint sounds on auscultation and muscle tenderness on palpation. In light of the small study sample and the absence of any substantial differences between the four groups, the role of malocclusion and orthodontic treatment in the aetiology of TMJ dysfunction remains obscure.

Full textAbstract:
Cephalometric radiography has been accepted worldwide as a powerful tool to study craniofacial growth, to diagnose deviations of an individual from population norms, and to plan orthodontic treatment and assess its progress and results, although it is not free from errors.
Chung, Runck, Bilben, Kau (1986) state that racial differences in craniofacial morphology are well recognized. Their study shows that the Oriental people including Japanese, Chinese, and Koreans, characterised by larger lateral dimensions Caucasians, as measured by bizygomatic diameter, bigonial diameter, and head breadth. The anteroposterior dimension as measured by head length shows the opposite trend. It is not known what genetic forces are responsible for maintaining these racial differences.
As a result, and as also proved by many cephalometric studies on different races, different race gives different appearance cephalometrically too.
The aim of this study is to find the pattern of dyscrepancy in Class II division 1 malocclusion in Indonesian people. The Indonesian is the outcome of the intermingling of many ancient races. If the "normal" occlusion of Asian people appears with certain unique cephalometric characteristics when comparison is made with the Caucasians norms, it seems logical to assume that the "abnormal" occlusion will show unique characteristics as well.

O objetivo do presente estudo foi avaliar a presença da inclinação dentária compensatória dos dentes anteriores superiores e inferiores em indivíduos com má oclusão do Padrão III e Padrão I não submetidos ao tratamento ortopédico e ou ortodôntico prévio. A seleção da amostra foi realizada a partir dos cursos de pós graduação e ou clínicas de Ortodontia nas cidades de Maringá – Pr e Blumenau – SC, de indivíduos que buscavam o tratamento ortodôntico pela primeira vez. Os indivíduos foram selecionados morfologicamente com base na classificação proposta por Capelozza Filho (2004) em Padrão I e Padrão III. Outros critérios de inclusão na amostra foram: ausência de tratamento ortopédico e ou ortodôntico prévio; dentadura permanente completa (com exceção dos terceiros molares); indivíduos com crescimento craniofacial finalizado e ausência de reabilitações protéticas. Vinte e oito indivíduos de ambos os gêneros foram selecionados e divididos em dois grupos: Grupo 1 – Padrão I (n=14) e Grupo 2 – Padrão III (n=14), com idade entre 17 anos e 1 mês a 35 anos e 3 meses. As imagens tomográficas foram obtidas por meio do tomógrafo i-CAT (Imaging Science International, Pennsylvania, EUA) e para a mensuração das inclinações dentárias utilizou-se o software Dolphin Imaging 3D (v 11.0, Dolphin Imaging, Chatsworth, Califórnia, EUA). Após a coleta dos dados e aplicação dos testes estatísticos observou-se a presença de compensações dentárias nos indivíduos Padrão III, expressa pela inclinação vestibular dos incisivos superiores e inclinação lingual dos inferiores. Além disso, os caninos também acompanharam essa tendência de compensação dos incisivos superiores e inferiores
The aim of the present study was to assess compensatory tooth inclination in the upper and lower arches in individuals with Pattern III and Pattern I malocclusion having undergone no previous orthopedic or orthodontic treatment. The sample selection was carried out at postgraduate courses and orthodontic clinics in the cities of Maringá (state of Paraná) and Blumenau (state of Santa Catarina), Brazil, with the recruitment of individuals seeking orthodontic treatment for the first time. The individuals were selected morphologically (Patterns I and III) based on the classification proposed by Capelozza Filho (2004). The following were the additional inclusion criteria: absence of previous orthopedic or orthodontic treatment; complete permanent dentition (with exception of third molars); finalized craniofacial growth; and absence of dental prostheses. Twenty-eight male and female individuals (age range: 17 years one month to 35 years three months) were divided into two groups: Group 1 – Pattern I (n=14) and Group 2 – Pattern III (n=14). Tomographic images were obtained using the i-CAT dental imaging system (Imaging Science International, Pennsylvania, USA). The Dolphin Imaging 3D program (v 11.0, Dolphin Imaging, Chatsworth, California, USA) was used for measuring tooth inclinations. After the data acquisition and application of the statistical tests, compensations were observed in the individuals with Pattern III malocclusion, as expressed by the vestibular inclination of the upper incisors and the lingual inclination of the lower incisors. The canines did not accompany this tendency of compensation among the upper and lower incisors

Resumo: O conhecimento das influencias funcionais, ambientais e genéticas sobre o crescimento e desenvolvimento craniofacial é abrangente e difícil de quantificar, mas de suma importância para a prevenção de alterações que possam influenciar negativamente o desenvolvimento adequado dos maxilares e estruturas relacionadas. Sendo assim, a pesquisa teve o objetivo de avaliar a relação entre disfunção orofacial, morfologia craniofacial e da oclusão, força de mordida (FM) e performance mastigatória (PM) em crianças e adolescentes. Três estudos foram conduzidos e serão apresentados a seguir na forma de capítulos. O primeiro e segundo estudos buscaram avaliar a relação entre disfunção orofacial, PM, morfologia craniofacial e da oclusão, FM e bruxismo do sono. Para tanto, foram incluídas 316 crianças e adolescentes, de ambos os gêneros, divididas em quatro grupos: sujeitos com dentição mista inicial (n=20), mista intermediária (n=73), mista final (n=89) e permanente (n=134). A PM foi avaliada pela técnica de peneiragem, estimando-se a capacidade individual do sujeito em triturar um alimento-teste e determinando o tamanho mediano das partículas (X50) e a distribuição das mesmas nas diferentes peneiras (b). As disfunções orofaciais e a necessidade de tratamento ortodôntico foram avaliadas por meio do instrumento The Nordic Orofacial Test Screnning (NOT-S) e pelo Índice de Necessidade de Tratamento Ortodôntico (IOTN), respectivamente. A máxima FM foi mensurada utilizando-se um gnatodinamômetro digital e a morfologia craniofacial foi avaliada por meio de análise cefalométrica em norma lateral e frontal. A presença de bruxismo do sono também foi verificada por meio da avaliação de facetas de desgaste em incisivos e/ou primeiros molares permanentes e do relato de sons de ranger/bater os dentes pelos responsáveis/irmãos. Os resultados foram submetidos à estatística descritiva, testes de normalidade e correlação, análise de variância e regressão linear múltipla para se verificar quais variáveis em estudo contribuíram para a variação em X50 e nos escores do NOT-S. A variância de X50 e b mostrou-se estatisticamente significativa entre os grupos; já os escores do NOT-S não mostraram diferença entre as fases das dentições. Idade, índice de massa corporal, FM e presença de bruxismo relacionaram-se significativamente com uma melhor PM. A presença de selamento labial e maior trespasse vertical relacionaram-se com menores escores totais do NOT-S, enquanto a idade e a presença de bruxismo exacerbaram os escores de disfunção orofacial. Além disso, não foi observada correlação significativa entre morfologia craniofacial e escores de disfunção orofacial. Concluiu-se que o índice de massa corporal, força de mordida e presença de bruxismo contribuíram para uma melhor PM; enquanto o aumento nos escores de disfunção orofacial relacionou-se a uma PM prejudicada. Além disso, o aumento do trespasse vertical e a presença de selamento labial relacionaram-se a menores escores de disfunção orofacial em indivíduos jovens. O terceiro capítulo aborda o estudo do dimorfismo facial e sua relação com as dimensões craniofaciais e dos arcos dentários e espessura ultrassonográfica do músculo masseter em crianças na fase de dentição mista. O estudo envolveu 32 crianças (14?/18?), com oclusão normal, e avaliou as dimensões craniofaciais por meio de telerradiografias em norma frontal. Os resultados foram submetidos à estatística descritiva, teste de normalidade, teste ?t? e regressão linear múltipla para se verificar a diferença entre os gêneros e quais variáveis contribuíram para a variação da medida da largura facial. Apesar da comparação da largura facial entre gêneros ter mostrado diferença significativa, quando se verificaram quais variáveis em estudo contribuíram para esta variação, observou-se que o índice de massa corporal, espessura do masseter, distância intermolares inferiores e intercaninos superiores e largura intermolar maxilar foram as variáveis significativamente relacionadas com a largura facial, enquanto o gênero não alcançou nível significativo. Concluiu-se assim que as variáveis funcionais e morfológicas do sistema estomatognático mostraram forte relação com a largura da face
Abstract: Knowledge of the functional, environmental and genetic influences on the craniofacial growth and development is comprehensive and difficult to quantify, but very important to prevent changes that may affect the proper development of the jaws and related structures. Therefore, this study aimed to evaluate the relationship between orofacial dysfunction, occlusal and craniofacial morphology, bite force (BF) and masticatory performance (MP) in children and adolescents. Three studies were conducted and are presented below in the form of chapters. The first and second study aimed to evaluate the relationship among orofacial dysfunction, MP, occlusal and craniofacial morphology, BF and sleep bruxism. The sample included 316 children and adolescents of both genders, divided into four groups: subjects with early (n=20), intermediate (n=73), late mixed (n=89) and permanent (n=134). MP was assessed by sieving technique and verifying the individual's ability to comminute an artificial test food in order to determine median particle size (X50) and distribution of particles in the different sieves (?b?). The orofacial dysfunction and need for orthodontic treatment were evaluated using the instrument The Nordic Orofacial Test-Screnning (NOT-S) and the Index of Orthodontic Treatment Need (IOTN), respectively. Maximum BF was measured using a digital gantodinamometer and craniofacial morphology was assessed by means of lateral and posteroanterior cephalometric analysis. The signs and symptoms of sleep bruxism were recorded taking into account the presence of shiny and polish facets on incisors and/or first permanent molar and sibling/parental report of grinding sounds. The results were submitted to descriptive statistics, normality and correlation tests, analysis of variance and multiple linear regression to determine which variables significantly contributed to X50 and scores on NOT-S variation. The variance of b and X50 were statistically significant between groups, whereas scores of NOT-S showed no difference among the stages of dentition. Age, body mass index, BF and the presence of bruxism was significantly correlated with better MP. The presence of closed lip posture and increased overbite measurements were related to lower total scores on NOT-S, whereas age and the presence of bruxism exacerbated orofacial dysfunction scores. In addition, a significant relation between craniofacial morphology and orofacial dysfunction was not found. It was concluded that body mass index, BF and the presence of sleep bruxism contributed to a better PM, while the increase in the scores of orofacial dysfunction was related to a worse PM. In addition, increased overbite measurement and closed lip posture related to lower scores of orofacial dysfunction in young individuals. The third chapter discusses the study of facial dimorphism and its relation with craniofacial and dental arches dimensions and ultrasonographic thickness of the masseter muscle in children in the mixed dentition. The study included 32 children (14?/18?) with normal occlusion and craniofacial dimensions were assessed by frontal radiographs. The results were submitted to descriptive statistics, normality test, "t" test and multiple linear regression to determine the difference between genders and which variables significantly contributed to the variation in facial width. Although the comparison of facial width between genders have shown significant differences, when the others studied variables were tested, it was observed that body mass index, masseter thickness, lower intermolar distance, upper intercanines distance and maxillary intermolar width were the variables that significantly related to facial width, while gender did not reach significant level. It was concluded that the functional and morphological variables of the stomatognathic system showed a strong relation with face width

Full textAbstract:
Occlusal asymmetries are common in orthodontic patients. A treatment option for correcting moderate asymmetries is asymmetric extractions. This study evaluated post-treatment dental arch symmetry in patients treated with unilateral premolar extractions. Post-treatment casts of 60 patients were divided into four treatment groups based on the history of occlusal asymmetry and the treatment plan. DesignCAD3000 software (Upperspace Corporation, Pryor, OK) was used to evaluate asymmetrically treated arches for symmetry. The four treatment groups were compared to identify differences in arch asymmetry based on treatment. The lateral incisor and canine were found to be more palatal on the extraction side in patients treated with unilateral extractions (P < .001). Arch length increased (P < 0.001) and area under the arch decreased (P < 0.01) on the extraction side. On average, patients with asymmetric extractions did not finish with more arch asymmetry than those without asymmetric extractions.

Objetivos: O objetivo deste estudo foi comparar os efeitos da desoclusão pelo canino, em comparação à oclusão balanceada bilateral, sobre a satisfação e parâmetros cinesiográficos de usuários de próteses totais, por meio de um estudo “cross-over”. Material e Métodos: Cinquenta pacientes desdentados receberam novas próteses totais bimaxilares. Após ajustes intra-orais e um período de adaptação, 44 participantes foram incluídos no estudo e receberam aleatoriamente uma sequência de esquemas oclusais: oclusão balanceada bilateral seguida de desoclusão pelo canino, ou desoclusão pelo canino seguida de oclusão balanceada bilateral. As avaliações foram realizadas após 30 dias de cada esquema oclusal. Os participantes responderam a um questionário de satisfação com as próteses e um cinesiógrafo registrou os movimentos mandibulares fisiológicos e o movimento da prótese total maxilar durante a mastigação. O teste de Wilcoxon e o teste t de Student foram utilizados para comparar os níveis de satisfação e os dados cinesiográficos para cada esquema oclusal, respectivamente (α = 0,05). Resultados: Os resultados não mostraram diferenças entre os esquemas oclusais em relação à satisfação dos participantes e em nenhum dos parâmetros cinesiográficos avaliados, exceto para a intrusão vertical da prótese maxilar durante a mastigação, que foi 0,1mm menor com a desoclusão pelo canino. Conclusão: Pode-se concluir que: 1) A satisfação de pacientes desdentados com as próteses totais não é influenciada pelo esquema oclusal; 2) Os movimentos mandibulares de abertura e fechamento, o espaço funcional livre e os movimentos da mandíbula durante a mastigação não são alterados em função da utilização da oclusão balanceada bilateral ou desoclusão pelo canino; 3) A desoclusão pelo canino promove menor intrusão da prótese total superior, embora...
Objectives: The objective of this study was to compare the effects of canine guidance and bilateral balanced occlusion on satisfaction and kinesiographic parameters of complete denture wearers, by means of a cross-over trial. Material and Methods: Fifty edentulous patients received new maxillary and mandibular complete dentures. After the intraoral adjustments and adaptation period, 44 participants were enrolled in the trial and randomly received a sequence of occlusal schemes: bilateral balanced occlusion followed by canine guidance, or canine guidance followed by bilateral balanced occlusion. The evaluations were performed after 30 days of each occlusal scheme. Participants answered a denture satisfaction questionnaire and a kinesiograph instrument recorded mandibular physiologic movements and pattern of maxillary denture movement during chewing. Wilcoxon test and paired sample t-test were used to compare satisfaction levels and kinesiographic data for each occlusal scheme, respectively (α= .05). Results: The results showed no differences between occlusal schemes on participant’s satisfaction and in any of the kinesiographic parameters studied, except for the vertical intrusion of the maxillary complete denture during chewing, which was .1mm lower with canine guidance. Conclusion: It can be concluded that: 1) The satisfaction of edentulous patients with theirs dentures is not influenced by occlusal scheme; 2) The mandibular movements of opening and closing, the freeway space and the jaw movement during chewing are not altered by the use of the bilateral balanced occlusion or canine guidance in their dentures, 3) The canine guidance promotes less intrusion of the maxillary complete dentures, although the values found are not clinically relevant; 4) The canine guidance or bilateral balanced occlusion are appropriate occlusal scheme and recommended for making...

We surveyed subjective symptoms of 600 patients referred to the Occlusion and Craniomandibular Dysfunction Center of the School of Dentistry, Campus of São José dos Campos São Paulo, Brazil. We have only considered those symptoms reported by the patients as major complaints. Our purpose on this project was to draw a profile of the disease considering sex, age and incidence of the symptoms that presented themselves or associated with others. Findings were that we found a significant larger number of women, 82.83%, comparing with 17.17% of men. Most of the patients belonged to the third decade, followed by the fourth and second. The most frequent symptom was pain on TMJ region, 42%, followed by TMJ noises, 26.6%, facial pain, 15.5%, earache, 14.5% and headache, 12.1%. The symptom TMJ noises showed to be statistically more significant in men, while headaches, pain in the neck region and temporary locking were more frequent in women. The most frequent association between two symptoms was: TMJ noises with TMJ pain, earache with headache and TMJ pain with earache. There was no statistical difference between sexes. The most frequent association of three symptoms was: TMJ noises together with TMJ pain and pain or difficulty in chewing

Resumo: O objetivo do presente estudo foi avaliar a presença da inclinação dentária compensatória dos dentes anteriores superiores e inferiores em indivíduos com má oclusão do Padrão III e Padrão I não submetidos ao tratamento ortopédico e ou ortodôntico prévio. A seleção da amostra foi realizada a partir dos cursos de pós graduação e ou clínicas de Ortodontia nas cidades de Maringá - Pr e Blumenau - SC, de indivíduos que buscavam o tratamento ortodôntico pela primeira vez. Os indivíduos foram selecionados morfologicamente com base na classificação proposta por Capelozza Filho (2004) em Padrão I e Padrão III. Outros critérios de inclusão na amostra foram: ausência de tratamento ortopédico e ou ortodôntico prévio; dentadura permanente completa (com exceção dos terceiros molares); indivíduos com crescimento craniofacial finalizado e ausência de reabilitações protéticas. Vinte e oito indivíduos de ambos os gêneros foram selecionados e divididos em dois grupos: Grupo 1 - Padrão I (n=14) e Grupo 2 - Padrão III (n=14), com idade entre 17 anos e 1 mês a 35 anos e 3 meses. As imagens tomográficas foram obtidas por meio do tomógrafo i-CAT (Imaging Science International, Pennsylvania, EUA) e para a mensuração das inclinações dentárias utilizou-se o software Dolphin Imaging 3D (v 11.0, Dolphin Imaging, Chatsworth, Califórnia, EUA). Após a coleta dos dados e aplicação dos testes estatísticos observou-se a presença de compensações dentárias nos indivíduos Padrão III, expressa pela inclinação vestibular dos incisivos superiores e inclinação lingual dos inferiores. Além disso, os caninos também acompanharam essa tendência de compensação dos incisivos superiores e inferiores
Abstract: The aim of the present study was to assess compensatory tooth inclination in the upper and lower arches in individuals with Pattern III and Pattern I malocclusion having undergone no previous orthopedic or orthodontic treatment. The sample selection was carried out at postgraduate courses and orthodontic clinics in the cities of Maringá (state of Paraná) and Blumenau (state of Santa Catarina), Brazil, with the recruitment of individuals seeking orthodontic treatment for the first time. The individuals were selected morphologically (Patterns I and III) based on the classification proposed by Capelozza Filho (2004). The following were the additional inclusion criteria: absence of previous orthopedic or orthodontic treatment; complete permanent dentition (with exception of third molars); finalized craniofacial growth; and absence of dental prostheses. Twenty-eight male and female individuals (age range: 17 years one month to 35 years three months) were divided into two groups: Group 1 - Pattern I (n=14) and Group 2 - Pattern III (n=14). Tomographic images were obtained using the i-CAT dental imaging system (Imaging Science International, Pennsylvania, USA). The Dolphin Imaging 3D program (v 11.0, Dolphin Imaging, Chatsworth, California, USA) was used for measuring tooth inclinations. After the data acquisition and application of the statistical tests, compensations were observed in the individuals with Pattern III malocclusion, as expressed by the vestibular inclination of the upper incisors and the lingual inclination of the lower incisors. The canines did not accompany this tendency of compensation among the upper and lower incisors

Acreditamos que estas amostras possam influenciar decisivamente os resultados e conclusões. Baseados nesta suposição, tivemos como proposição estudar dois subgrupos homogêneos: indivíduos classificados pelo Índice de Helkimo com totalmente livres de sintomas (Ai 0 e Di 0) e com sintomas de DCM (Ai II ou Di II-III). Estes grupos foram analisados quanto ao Índice Oclusal (Oi) e a fatores psicológicos confirmados pelo Questionário de Saúde Geral de Goldberg (QSG). Examinamos cinqüenta indivíduos, quatro homens e 46 mutheres (13 a 49 anos com média de 28, l anos) com DCM e cinqüenta, 14 homens e 36 mutheres (20 a 56 anos com média de 25, I) Concluímos que a má oclusão foi ligeiramente maior em indivíduos com DCM, entretanto, sem significância estatística. Estresse e outros distúrbios psicológicos foram ligeiramente maiores em indivíduos com DCM, com significância estatística para o distúrbio do sono. A presença associada de fatores psicológicos ou má oclusão ou ambos teve uma distribuição uniforme e semelhante entre os dois grupos. A ausência simultânea de ambos os fatores foi, com significância estatística, maior no grupo de indivíduos sem DCM. O auto-relato de bruxismo e parafunções foi ligeiramente maior nos indivíduos com DCM sendo que o apertamento diurno foi maior, com significância estatística. A associação de má oclusão e bruxismo mostrou-se semelhante nos dois grupos, mas a associação de estresse e bruxismo foi, com significância estatística, maior nos individuos com DCM
The general population, not related as patients, can not be considered completely free of Cranio Mandibular Dysfunction (CMD) because epidemiological studies have been showing that up to 70% of aleatory individuals present signs or symptoms of this disorder. We believe they can influence the results and conclusions. Our purpose, based on this supposition, was to study two homogeneous sub-groups: individuals, classified by Helkimo 's Index as completely free of signs and symptoms (Ai 0, Di0) and with CMD (Ai II or Di II-III). These samples were analyzed considering the Occlusion Index, (Oi) and through a psychological test, Goldberg 's General Health Questionnaire (GHQ). We examined 50 people, 4 men and 46 women, affected with CMD (aged 13-49 years old with a mean of 28.1 years) and 50 more, 14 men and 36 women, without CMD (aged 20-56 years old with a mean of 25.1 years). Our results were tested by chi-square. We concluded that malocclusion was slightly more prevalente in CDM individuals, although not significant. Stress and other psychological factors were also slightly higher in individuals with CMD, with significance for sleep disturbances. The association of both factors were distributed evenly between the two groups, but the simultaneous absence of the factors was significantly higher in the people with no signs and symptoms. Self-related bruxism and oral parafunctions were slightly higher in CMD individuals with significance for clenching. The association between malocclusion and bruxism was similar for both groups, but the association between stress and bruxism was significantly higher for CMD individuals

Resumo: Uma população aleatória de indivíduos que não procuraram por tratamento não podem ser considerados como totalmente livres de sinais e sintomas de Disfunção Craniomandibular (DCM), porque estudos epidemiológicos têm demonstrado que até 70% da população apresenta algum sinal ou sintoma de disfunção. Acreditamos que estas amostras possam influenciar decisivamente os resultados e conclusões. Baseados nesta suposição, tivemos como proposição estudar dois subgrupos homogêneos: indivíduos classificados pelo Índice de Helkimo com totalmente livres de sintomas (Ai 0 e Di 0) e com sintomas de DCM (Ai II ou Di II-III). Estes grupos foram analisados quanto ao Índice Oclusal (Oi) e a fatores psicológicos confirmados pelo Questionário de Saúde Geral de Goldberg (QSG). Examinamos cinqüenta indivíduos, quatro homens e 46 mutheres (13 a 49 anos com média de 28, l anos) com DCM e cinqüenta, 14 homens e 36 mutheres (20 a 56 anos com média de 25, I) Concluímos que a má oclusão foi ligeiramente maior em indivíduos com DCM, entretanto, sem significância estatística. Estresse e outros distúrbios psicológicos foram ligeiramente maiores em indivíduos com DCM, com significância estatística para o distúrbio do sono. A presença associada de fatores psicológicos ou má oclusão ou ambos teve uma distribuição uniforme e semelhante entre os dois grupos. A ausência simultânea de ambos os fatores foi, com significância estatística, maior no grupo de indivíduos sem DCM. O auto-relato de bruxismo e parafunções foi ligeiramente maior nos indivíduos com DCM sendo que o apertamento diurno foi maior, com significância estatística. A associação de má oclusão e bruxismo mostrou-se semelhante nos dois grupos, mas a associação de estresse e bruxismo foi, com significância estatística, maior nos individuos com DCM
Abstract: The general population, not related as patients, can not be considered completely free of Cranio Mandibular Dysfunction (CMD) because epidemiological studies have been showing that up to 70% of aleatory individuals present signs or symptoms of this disorder. We believe they can influence the results and conclusions. Our purpose, based on this supposition, was to study two homogeneous sub-groups: individuals, classified by Helkimo 's Index as completely free of signs and symptoms (Ai 0, Di0) and with CMD (Ai II or Di II-III). These samples were analyzed considering the Occlusion Index, (Oi) and through a psychological test, Goldberg 's General Health Questionnaire (GHQ). We examined 50 people, 4 men and 46 women, affected with CMD (aged 13-49 years old with a mean of 28.1 years) and 50 more, 14 men and 36 women, without CMD (aged 20-56 years old with a mean of 25.1 years). Our results were tested by chi-square. We concluded that malocclusion was slightly more prevalente in CDM individuals, although not significant. Stress and other psychological factors were also slightly higher in individuals with CMD, with significance for sleep disturbances. The association of both factors were distributed evenly between the two groups, but the simultaneous absence of the factors was significantly higher in the people with no signs and symptoms. Self-related bruxism and oral parafunctions were slightly higher in CMD individuals with significance for clenching. The association between malocclusion and bruxism was similar for both groups, but the association between stress and bruxism was significantly higher for CMD individuals

Full textAbstract:
Epidemiological studies on malocclusion have been primarily concerned with its aetiology and distribution. However, due to the varied and often subjective methods of assessment, many of these studies provide conflicting data related to malocclusions (Solow, 1970). To address this, the Fédé
ration Dentaire Internationale (FDI) in close collaboration with the World Health Organisation (WHO) developed an objective method for measuring occlusal traits (Baume et al., 1973). This method was used to obtain the epidemiological data on occlusal traits for 14-year-old children Kampala in order to provide baseline data related to malocclusion. A total of 402 subjects were examined. Of these 65% were female and 35% were male. Thirty percent of the sample had at least one dental anomaly. The most commonly extracted teeth were mandibular first molars (43.6%) and maxillary canines (17.3%). The high frequency of extracted permanent canines in this sample is unique. By and large, many of the occlusal traits related to the canine are attributable to the practice of ebinyo, a form of dental mutilation, which still seem to be rife in many communities in Uganda. Similar to other studies (Massler and Frankel, 1951
de MuÅiz, 1986
Ferguson, 1988
Kaka, 1993), mandibular first molars were five times more likely to be missing than maxillary first molars while the ratio of missing maxillary to mandibular canines was found to be 2.5:1. Crowding was most frequently observed in the mandibular incisal segment while spacing was mostly in the maxillary incisal region, thus supporting the view of Brunelle et al., (1996) that although prevalence may vary from study to study, more people have malaligned mandibular incisors than maxillary incisors concurs with these studies. Of the subjects studied, 6.8% had a diastema of 3mm and more. Regarding space measurements, 17.9% of the sample population had at least one segment with crowding, 18.2% had at least one segment with spacing while 33.6% had some degree of incisor malalignment and 54.2% of the sample population had some form of space anomaly. About 70% of the subjects had symmetric molar relationships of which 54.2% were Class I, 9.2% Class II and 3.2% Class III similar to the universal distributional pattern. Crossbites were not a major finding, and were present in only 7% of the sample. The distribution of overjet was relatively symmetrical on the left and right. Negative overjet (anterior open bite) was a rare occurrence in an average of 2.4% of the population. In 77.6% of the population, the overjet ranged from 1 to 4mm, and in 22.4%, the overjet was either edge-to-edge, reverse or 5mm and over. About 7.3% had an overjet of 5-6mm while only 2.1% had an overjet greater than 6mm. Approximately 53.7% of the population had an overbite of 1-3mm. Edge-to-edge and open bite incisor relationships were found in less than 10% of the sample. Although ideal occlusion as described by Angle (1907) in the Ugandan sample is very rare, using the data derived from this study, normal occlusion as defined by statistical distribution can be described.

Full textAbstract:
Background: Maximal voluntary occlusal bite force (MVOBF) is the maximal force applied by the jaw muscles in dental occlusion. MVOBF is one parameter for functional capacity of the jaw system. Aim: To evaluate MVOBF in different positions in the bite and to evaluate possible intra-individual differences between sessions. Methods: MVOBF was measured with an electronic bite force device, with transducers sensitive to force, in 20 healthy men (mean 24.5 years). Eligibility of participants was full dental occlusion, Angle Class I relation, no diagnosis according to Diagnostic criteria for temporomandibular disorders. The test included three repeated measurements on each site: first molar right, first molar left and central incisor, in random order, with test-retest study design. Unpaired T-test was used to test the MVOBF in different positions in the bite and paired T-test for possible intra-individual differences between sessions. A post hoc test for repeated measure one-way ANOVA was added. Results: MVOBF in different positions in the bite was lower in the incisor area compared with the molar region (P<0.0001), but similar between right and left molar side (P=0.48 and P= 0.96, respectively). No intra-individual differences between sessions (molar right P= 0.40; molar left P= 0.81; incisor area P= 0.66). The intra-individual variability for repeated measurements showed variability for incisor area (P= 0.007), but not for molar right and left region (P=0.95 and P=0.49, respectively). Conclusion: The results may provide reference values for MVOBF in young adult men, to be compared with men with pain or dysfunction in the jaw system.

Full textAbstract:
A thesis submitted to the College of Dental Medicine of Nova Southeastern University of the degree of Master of Science in Dentistry.
Purpose: This study will evaluate the influence of different convergence angles and tooth preparation heights on the marginal adaptation and retention of allceramic CAD/CAM crowns. Materials & Methods: Seventy two typodont teeth (Ivorine teeth; Columbia Dentoform Corp, Long Island City, NY) were prepared using milling burs (Brasseler, USA) and a parallometer (PFG 100, Cendres and Metaux, Switzerland) with 1.0 mm rounded shoulder finish lines. Specimens were divided into 3 groups (n=24) according to 3, 4.5 and 6mm occluso-gingival (O-G) heights. The teeth within each group were then subdivided into 3 subgroups (8 in each sub-group) according to total occlusal convergence (TOC) of 8,16 and 22 degrees. Using the intra-oral camera wand of the Cerec AC machine (Sirona, Germany), optical impressions were made of each tooth. This data was then transferred to the Cerec MC XL milling unit for fabrication of all-ceramic crowns using IPS Empress II (Ivoclar Vivadent, US). The crowns were cemented on typodont teeth with glass ionomer cement. The marginal discrepancy was measured at 6 points with optical microscopy. Retention was evaluated by measuring the tensile force required to dislodge or break the crown from the corresponding tooth preparation in a universal testing machine. Data were analysed using Shapiro-Wilke tests for normality and Leven's tests for equal variances. To look for differences between groups, analysis of variance (ANOVA) with Tukey's HSD test was performed. Results: Mean marginal gap was 35.9 ± 18.4ìm to 81.4 ± 61.3ìm. 2- way ANOVA shows no significant difference in marginal gap among the groups (P< 0.05). The height mean retentive force 183.84 ± 27.0 N, was measured for 6mm height and 8° group and lowest force 86.01±10.75 N, was measured for 3 mm and 22° group. 2- way ANOVA with turkey's HSD test shows significant difference among the groups (P > 0.05). Conclusion: Marginal adaptation of the CAD/CAM all-ceramic crowns is comparable to conventional cast crowns. The preparation recommendation for conventional porcelain fused to metal crowns can be applied to CAD/CAM crown restorations. Retention of cemented CAD/CAM crowns is comparable to conventional cast crowns

Full textAbstract:
The newly emerging Clarity™ Clear Aligner System from 3M has set out to address one of the biggest pitfalls of thermoplastic aligners: accuracy of orthodontic movements. The 3M Clarity™ Clear Aligner System is unique among clear aligners because it employs a proprietary, sophisticated machine-learning algorithm to design orthodontic movement schematics. The core of the Clarity™ Aligner System is artificial intelligence, meaning that a prospective analysis of preliminary data is essential for the development and improvement of the accuracy of the algorithm. This study investigates movement and accuracy of the Clarity™ Aligner System, from a preliminary data subset from ongoing prospective, randomized clinical trials. Movement from the first trial subset is examined in terms of the following movement factors: secondary premolar-secondary premolar (5+5 in the Palmer system) arch expansion or crowding resolved, absolute rotation, absolute mesial-distal tipping, and absolute torque for both the crown and root. These movements are further examined according to specific tooth types.
Both actual observational orthodontic movements and theoretical movements are designed by the Clarity™ System. The accuracy of actual movement in terms of theoretical movements is calculated; however, it is impossible to calculate the significance of these accuracies due to a complete lack of benchmark movement values for the clear aligner market. There are no benchmark values to compare to, so orthodontic movements will be critically examined for performance, and casually compared to alternative aligner systems. Identifying potential weaknesses in the Clarity™ Aligner System is imperative for maximizing its effectiveness.

PURPOSE: To determine the prevalence of Sleep Disturbances (SD) in children and to evaluate the correlation between dental classification and airway dimensions.
METHODS: Children between 3 – 18 years at the Boston University Pediatric Oral Healthcare Center in Boston, Massachusetts were recruited for this study. Based on parents’ responses in a brief sleep-screening questionnaire, cases were identified as children with SD and controls were those without. Another detailed questionnaire was used to collect information on demographics and sleep patterns. Clinical and upper airway examinations were conducted using Eccovision Acoustic Rhinometer (AR) and Acoustic Pharyngometer (AP). Statistical differences in upper airway measurements by type of dental occlusion were evaluated.
RESULTS: Among 281 children, the prevalence of SD was 38%. Upper airway measurements among 176 participants using AP showed significantly higher pharyngeal Minimum Cross-Sectional Area (MCA) for class III dental occlusion compared to class I (P=.036) in children with SD. Statistically significant differences in MCA, Airway Volume (AV), and minimum distance to MCA by type of dental occlusion were mainly observed among children with SD (P<.05).
CONCLUSIONS: The results highlight a possible correlation between nasal and pharyngeal airway dimensions and dental classification among children with SD. Further analysis that include radiological examinations may help in confirming these findings.
