Is there a relation between harmful oral habits and facial typology and dental occlusion?

OBJETIVO: verificar se há predominância de hábitos orais deletérios nos diferentes tipos faciais eaprofundar o estudo da relação entre os hábitos orais deletérios e a oclusão dentária. MÉTODO: foram analisados 307 prontuários de pacientes entre 2 e 59 anos de idade de ambos os sexos, encaminhados ao ambulatório do Instituto CEFAC. Foram anotados dos prontuários os hábitos orais deletérios, oclusão dentária, tipologia facial, sexo e idade. RESULTADOS: observou-se que os hábitos com maior prevalência são: chupeta (125 indivíduos), ranger dentes (115 indivíduos) e mamadeira (102 indivíduos). Dentre as comparações estudadas, as que apresentaram diferença estatisticamente significante foram: a presença do uso da chupeta no grupo de 9 a 12 anos, quando comparado ao de 6 a 9 anos (p=0,0269); presença do hábito de ranger dentes no grupo de 3 a 6 anos quando comparado ao grupo com mais de 20 anos (p=0,0393); presença do hábito de ranger dentes no grupo de oclusão dentária classe I quando comparado ao classe III (p=0,0128) e presença de oclusão dentária classe I no sexo feminino quando comparado ao masculino (p=0,0177). CONCLUSÃO: não há relação entre os hábitos orais deletérios e a tipologia facial. Entretanto, há relação entre o hábito oral deletério de ranger dentes com a oclusão dentária Classe I de Angle.PURPOSE: to check whether there is a predominance of deleterious oral habits in different facial typesand further study of the relationship between harmful oral habits and dental occlusion. METHOD: we analyzed 307 cases of patients between 2 and 59-year old of both genders, referred to the outpatient clinic of CEFAC Institute. Were we registered medical records of deleterious oral habits, dental occlusion, facial type, gender and age. RESULTS: we observed that the following habits are most prevalent: pacifier (125 subjects), gnashing teeth (115 subjects) and bottle (102 individuals). Among the comparisons, the ones who showed statistical significance was the presence of pacifier use in the group from 9 to 12 years, compared to 6 to 9 years (p=0.0269), presence of habit of gnashing teeth in the group from 3 to 6 years when compared to more than 20 years (p = 0.0393), presence of the habit of gnashing teeth in the group of dental occlusion class I compared to class III (p = 0.0128) and presence dental occlusion class I in females compared to males (p=0.0177). CONCLUSION: there is no relationship between harmful oral habits and facial typology. However, there is a relationship between the harmful oral habit of grinding the teeth with Angle class I dental occlusion

Prevalence and characteristics of polycystic ovary syndrome in brazilian women : protocol for a nation-wide case-control study

Introduction Brazil is a large country, with a population of mixed ethnic background and broad variation in dietary and physical activity traits across its five main regions. Because data on Brazilian women with polycystic ovary syndrome (PCOS) are still scarce, a nation-wide collaborative study was designed to determine the prevalence of metabolic and reproductive abnormalities and the presence of anxiety and depression in Brazilian women with PCOS. In addition, the study aims at describing how these characteristics are distributed across PCOS phenotypes and at detecting associations with regional demographic and lifestyle aspects, genetic variants, and epigenetic markers. Methods and analysis The Brazilian PCOS study is being conducted in the outpatient clinics of eight university hospitals within the public healthcare network (Unified Health System) across the country. Additional centres will be included following completion of the research ethics approval process. The sample includes women with PCOS according to Rotterdam criteria at inclusion in the study and a control group of healthy women matched by age, socioeconomic status and geographical region. Data will be collected in each centre and incorporated into a unified cloud database. Clinical, demographic, socioeconomic, psychological, metabolic, epigenetic and genotypic variables will be evaluated. The data resulting from this study will be useful to guide specific public strategies for primary and secondary prevention of metabolic and reproductive comorbidities in the PCOS population of Brazil
