Pacientes portadores de deformidades dentofaciais podem relatar dificuldades de mastigação e fala, desordens temporomandibulares, preocupação com a imagem corporal e baixa autoestima. Frequentemente, buscam tratamento orto-cirúrgico pela motivação de obter melhora notável nos aspectos estético, funcional e psicossocial. A evidência atualmente disponível sobre os benefícios na qualidade de vida relacionada à saúde bucal desta modalidade terapêutica ainda não é conclusiva, devido à diversidade de metodologias adotadas entre os estudos existentes, majoritariamente realizados na América do Norte, Europa, Oriente Médio e Ásia. Logo, é essencial utilizar instrumentos específicos para avaliar os efeitos desta modalidade de tratamento também na vida diária dos pacientes brasileiros. O propósito do presente estudo transversal foi determinar o impacto que o tratamento orto-cirúrgico exerce sobre a percepção de qualidade de vida dos pacientes portadores de deformidades dentofaciais, bem como a influência exercida pelo gênero, idade, renda, escolaridade e características da má oclusão, nas quatro etapas inerentes a esta modalidade de tratamento: (1) Inicial; (2) Preparo ortodôntico para a cirurgia; (3) Pós-cirúrgico; e (4) Contenção (pós-tratamento). Duzentos e cinquenta e quatro pacientes foram entrevistados em três importantes centros de atendimento na cidade do Rio de Janeiro. A qualidade de vida foi avaliada pelos questionários OHIP-14 (Oral Health Impact Profile - Short Version) e pelo OQLQ (Orthognathic Quality of Life Questionnaire) em suas versões traduzidas e validadas para o português. A gravidade da má oclusão e autopercepção estética foram avaliadas com base no Índice de Necessidade de Tratamento Ortodôntico (IOTN) e pelo Índice de Estética Dental (DAI). A análise dos dados foi efetuada pelos testes qui-quadrado, Kruskal-Wallis e modelos de regressão binomial negativa múltipla. Os pacientes dos quatro grupos foram semelhantes em relação ao gênero (p = 0,463), escolaridade (p = 0,276) e renda familiar (p = 0,100). Entre os entrevistados houve o predomínio de mulheres, com ensino médio completo e renda familiar entre 2 e 3 salários mínimos, portadores de má oclusão de Classe III de Angle grave. No modelo de regressão binomial negativa ajustado para os fatores gênero, idade, renda familiar e escolaridade, a qualidade de vida aferida pelo OHIP-14 demonstrou que o grupo Inicial sofreu impactos mais negativos do que os grupos Pós-cirúrgico, Preparo e Contenção; o OQLQ indicou que o grupo Inicial sofreu impactos mais negativos do que os grupos Preparo, Pós-cirúrgico e Contenção, nesta sequência. Não foi detectada influência da idade, renda e escolaridade nestes resultados. Foi observado que o gênero feminino sofreu mais impacto negativo na qualidade de vida, principalmente nas dimensões relativas à função e a aspectos sociais. Concluiu-se que os pacientes que finalizaram o tratamento orto-cirúrgico apresentaram como benefícios menores impactos na qualidade de vida específica e relacionada à saúde bucal, melhor autopercepção estética e menor gravidade da má oclusão, em comparação aos pacientes nas etapas pré e pós-cirúrgica e aos pacientes portadores de deformidades dentofaciais em busca de tratamento.

In the last decade, an increasing number of studies focusing on the impact of oral deformities on quality of life have been published. However, the evaluation of patients at different phases of the treatment has not been performed. Therefore, the purpose of this study was to determine the impact that dentofacial deformities have on patients` quality of life, as well as the influence exerted by social, economic, demographic and orthodontic factors, type and severity of malocclusion. A bicentric study - of the cross-sectional type of repeated panels - involving two cities - Natal and Rio de Janeiro - was carried out. A total of 227 patients participated in the study: 71 patients in the initial phase of the treatment (before any orthosurgical procedure), 115 patients in the pre-surgical (with braces) phase and 41 patients in the postoperative phase. The quality of life was measured using the Orthognatic Quality of Life Questionnnaire - OQLQ, translated and validated into Portuguese. The normative and aesthetic need for treatment was assessed with the Index of Orthodontic Treatment Need (IOTN) and the Dental Aesthetic Index (DAI); the social, economic and demographic factors, the type of service and malocclusion were also assessed. The data were analyzed through χ2/ Fisher`s exact test to seek the association between the nominal categorical variables in the three phases of treatment, Mann Whitney and Kruskal-Wallis test for gauging the existence of significant differences between two and three groups regarding each domain of OQLQ, respectively. For all tests, it was adopted a significance level of 5%. There was a statistically significant difference (p <0.001) in the general scores of OQLQ and in the domains of social aspects, facial aesthetics and oral function, when the "postoperative group" was compared to the "initial" and "orthodontic preparation" groups. Women, single, aged between 31 and 59 and living in Natal had the greatest impact on quality of life among patients in the "orthodontic preparation" group. Only the variable "income" (2 to 3 minimum wages), for the "initial" group, and gender (female) for the "postoperative" group, showed significant association with quality of life. The normative variable IOTN (DHC and AC) showed significant association with the OQLQ for the "initial" group, and the IOTN-AC-auto in the group of orthodontic preparation, being less important to women. We conclude that the ortho-surgical therapy has positive effects on quality of life after orthognathic surgery

Instruments are used in odontology to measure the Quality of Life Related to Oral Health (OHRQoL) to scale how the oral condition interferes with functional areas, of the people s psychological and social life. This cross-sectional study, held in Natal/RN, with 215 students from the Federal Institute of Education, Science and Technology of Rio Grande do Norte (IFRN) has investigated the association between the performance of daily activities and oral health status of school adolescents from 15 to 19 years of age, through the normative index DMFT (permanent teeth decayed, missing and filled), CPI (Community Periodontal Index) and DAI (dental Aesthetic Index) and subjective questionnaire assessment of quality of life related oral health OIDP index (oral impacts on daily performance). It was also carried out the socioeconomic characteristics of students through IFRN own data. Concerning the analysis of data was performed a descriptive analysis of the variables by their absolute and relative frequencies and measures of central tendency. The chi-square test was used to assess the association between the dependent variable and the independent categorical variables and the Student t test for quantitative. It was also conducted a further multiple analysis out using Poisson regression with robust variance between the outcome "presence of impact" and the independent variables that showed p <0.20. It was used for all the statistical tests a significance level of 5%. Among the adolescents surveyed, 51.16% reported that at least one activity assessed by OIDP had hampered its implementation due to some dental problem. The difficulties were more pronounced in the activities of eating (31.6%), oral hygiene (25.6%) and smile (25.1%).The tooth position, followed by toothache, were the causes of the impacts reported by most teenagers. There was a significant association between the presence and impact of the presence of one or more decayed teeth (p = 0.012), the presence of gum bleeding (p = 0.012) and for orthodontic treatment (p = 0.003), independently of other variables. There was no significant association between oral health status and socioeconomic and demographic characteristics of the adolescents. The survey results showed that there is an association between oral health status of the population studied and reports of difficulties in carrying out daily activities evaluated. The worse the oral health status, the greater the impact of this condition on the adolescents quality of life

The composite resin is the material of election for direct restorations in posterior teeth currently. The restorative dentistry aims to improve each day the material and facilitate the restorative technique. This paper describes the technique of occlusal matrix made to speed up and preservation the occlusal surface of a first molar tooth affected by caries lesion. A new resin-based composite was used called Silorane, which may be placed in larger increments due the material has low shrinkage and polymerization stress. The use of occlusal matrix associated with a low shrinkage resin composite can simplify the clinical work, and result in a restoration with excellent reproduction of anatomical.

The aim of this study was to evaluate the occlusal condition of 12 year-old children examined by the Oral Health Brazil 2003 Project in Cáceres city. The sample consisted of 170 children, boys and girls, selected at random among 20 schools that took part in this project. It was used for the analysis of the occlusal condition the Dental Aesthetic Index (DAI), as manual of basic epidemic rising in Oral Health extolled by the World Health Organization which describes the occlusal conditions in relation to dentition, space and occlusion of the permanent dentition. It was observed that the prevalence of the normal occlusion and of the malocclusion were, respectively, 21.18% and 78.82%. This last one was present due to the tooth crowding (74.93%), spacing in the incisor segment (23.88%), diastema (17.17%), anterior maxillary misalignment (58.95%) and anterior mandibular (61.19%), excessive overjet (11.94%), negative overjet (4.47%), open bite (1.5%) and molar relationship Class II or III (26.87%). It was concluded that the studied sample presents a high index of factors to compose the malocclusion.

A quebra da harmonia do sorriso dos pacientes pode ser decorrente da redução da quantidade de mineral depositado, ocasionando um defeito qualitativo considerado como hipocalcificação2. A hipocalcificação de carácter adquirido local nos dentes anteriores é muito comum devido ao trauma ou lesão periapical nos dentes decíduos, que podem levar à alteração da formação dos germes dos dentes permanentes1. Essas anomalias podem se apresentar em diferentes tamanhos e profundidades e, por isso, os tratamentos a serem realizados variam desde os mais conservadores, como clareamento ou microabrasão, até os mais invasivos, como facetas indiretas ou coroas totais, além da associação desses tratamentos quando existir a necessidade. As alterações hipocalcificadas profundas que acometem toda espessura do esmalte e apresentam alteração de cor com comprometimento da estética, necessitam de desgaste e posterior restauração adesiva para estabelecer a estética dental. As resinas compostas vêm sendo amplamente utilizadas nesses casos devido às suas características óticas de translucides e opacidade, além das suas propriedades adesivas e mecânicas, como resistência, durabilidade, selamento marginal, manutenção da cor e lisura superficial. O caso apresentado é de um paciente do sexo masculino, 12 anos, que compareceu à clínica relatando insatisfação com a mancha presente no dente anterior. Após anamnese e exame clínico, constatou-se um comprometimento parcial da calcificação da face vestibular do incisivo central superior permanente (21) (hipocalcificação adquirida de caráter local)1. Após exame clínico e radiográfico, o tratamento proposto foi o restabelecimento da estética do elemento 21, que se encontrava com alteração de cor, através de desgaste do esmalte e restauração adesiva estética. Ao observar o aspecto final da restauração após o acabamento e polimento e o sorriso final do paciente, pôde-se comprovar o excelente resultado estético conseguido com o procedimento restaurador direto associado à muralha vestibular confeccionada com cimento provisório fotoativado.

Este estudo objetiva encontrar a forma e dimensão de arcos dentais para definir a forma de um arco contínuo que possa ser utilizado na técnica lingual. A amostra foi composta de 70 indivíduos brasileiros, leucodermas, com oclusão normal natural, que apresentaram no mínimo quatro das seis chaves de oclusão de Andrews. Esta amostra possui 40% de indivíduos do sexo masculino (28 homens) e 60% do sexo feminino (42 mulheres) com idade média de 16,4a. Os modelos dos arcos dentais da maxila e mandíbula foram digitalizados (3D) e as imagens exportadas para o software Delcam Power SHAPE® 2010 (Birmingham, U.K.). Foram selecionados pontos nas superfícies linguais dos dentes e traçadas 14 medidas para determinar a forma e a dimensão do arco dental. O teste de Shapiro-Wilk possibilitou definir uma forma de arco pequeno utilizando o percentil 25% (P25%), um arco médio (média) e uma forma de arco grande pelo percentil 75% (P75%). O teste t-student comparou se houve uma diferença entre os sexos, e foram encontrados 12 tamanhos de arcos dentais (6 para o sexo feminino e 6 para o sexo masculino). Em todos os testes estatísticos foi adotado nível de significância de 5% (p<0,05). A partir dos resultados obtidos, foi possível definir uma forma de arco contínuo para ser utilizado na técnica Lingual Straight Wire (LSW) - parábola levemente achatada na região anterior - e, devido à similaridade entre alguns tamanhos de arcos dentais, encontrados pelo dimorfismo sexual, pôde ser elaborado um diagrama de arcos de maneira mais simplificada.

OBJECTIVE: To describe the distribution of malocclusion and its associated factors in Brazilian adolescents. METHODS: Data from 7,328 subjects aged 12 years and 5,445 adolescents aged 15-19 years were analyzed. The adolescents took part in the Brazilian Oral Health Survey (SBBrasil 2010). The outcome was severe malocclusion according to the dental aesthetic index. The independent variables were sex, skin color, monthly household income, possessions, number of individuals in the household, untreated dental caries, missing teeth and dental appointments or lack thereof, frequency, and reason. Logistical regression analysis was carried out, considering the complex sampling cluster design, based on a hierarchical model. RESULTS: The prevalence of severe malocclusion was 6.5% and 9.1% in the 12-year-olds and the 15-19-year-olds, respectively. After adjustment, those with lighter- skinned black or black skin were 1.59 (95%CI 1.08;2.34) times more likely to present the outcome compared with those with white skin. The loss of one or more first molars increased 2.66 (95%CI 1.26;5.63) the chance to present severe malocclusion by the age of 12. Adolescents aged 15-19 whose household income was below R$ 1,500.00 (OR 2.69 [95%CI 1.62; 4.47]) and those who had seen a dentist for treatment (OR 2.59 [95%CI 2.55;4.34]) had the greatest chance of having severe malocclusion compared with those with higher incomes and those who visited the dentist for prevention.

El objetivo del presente estudio fue relacionar los componentes de la proporción áurea con el parámetro facial de estudiantes de odontología en una universidad de la provincia de Chiclayo, 2014. El diseño del estudio fue transversal, descriptivo y prospectivo. La población de estudio fue representada por 88 estudiantes de una Escuela de Odontología, se diseñó una ficha de recolección según las medidas antropométricas craneofaciales. Se capacitó y se evaluó la estabilidad de la concordancia intra e interexaminador de los investigadores gracias a la participación de un Especialista en Ortodoncia, a fin de lograr una estandarización en las mediciones, verificado mediante una prueba T para muestras pareadas. Se encontró que el 65.91% del total de pacientes presentaban proporción áurea en su dimensión externa, 48.86 % son braquifaciales, 13.64 % mesofaciales, 3.41 % dolicofaciales Se encontró que el 57.95% del total presentaban proporción aurea en su relación vertical, 42.05% son braquifaciales, 10.23 % mesofaciales y 5.68% dolicofaciales. En cuanto al perfil armónico, el 70.45% del total de pacientes no presentan proporción áurea, de los cuales el 53.41% son braquifaciales, 10.23 % son mesofaciales y 6.82% son dolicofaciales. Para el contraste de la hipótesis se utilizó el coeficiente de correlación Chi cuadrado. Para todas las pruebas estadísticas el nivel de significancia fue de <5% (p<0,05) con un 95% de nivel de confiabilidad. Se concluyó que sólo existe relación significativa entre el componente dimensión externa de la proporción áurea y el parámetro facial de los estudiantes de odontología en una universidad de la provincia de Chiclayo.
