ABSTRACT
Objetivo verificar se existe relação entre a presença de disfunção temporomandibular (DTM) relacionada à variabilidade da dimensão vertical de oclusão em crianças e adolescentes na faixa etária de 7 a 12 anos. Métodos foram avaliadas 96 crianças e adolescentes do Instituto Rogacionista em São Paulo. A pesquisa diagnóstica da disfunção temporomandibular foi por meio do Índice de Helkimo e exame clínico posterior. Para a mensuração dos dados referentes à dimensão vertical foram empregadas as distâncias comissura labial - canto externo do olho e base do nariz – mento. A comparação dos valores médios das medidas antropométricas entre os gêneros e os grupos com e sem disfunção temporomandibular foi realizada empregando-se a análise de variância (ANOVA) complementada pelo teste least significance diference. Resultados a dimensão vertical de oclusão demonstrou medidas distintas nas crianças e adolescentes em todas as faixas etárias avaliadas, foram observadas alterações significantes dessa medida nas idades de 10 e 12 anos de ambos os gêneros. Conclusão pode -se concluir que na amostra estudada houve relação direta entre a presença de DTM e Dimensão vertical de oclusão (DVO), correlação positiva entre as medidas comissura labial – canto do olho externo e Násio – Mento no sexo feminino e alterações significantes na dimensão vertical de oclusão nas idades de 10 e 12 anos para ambos os sexos. .
Purpose to establish the relationship between the presence of temporomandibular disorders and variability of vertical dimension of occlusion aged between 7 and 12 years. Methods it was analyzed 96 children and adolescents of Rogacionista Institute in Sao Paulo, Brazil. The diagnostic investigation of temporomandibular disorders was through Helkimo index and subsequent clinical examination. To measure the data on the vertical dimension were employed distances labial - corner of his eye and nose base - ment. To compare the mean values of anthropometric measurements between genders and the groups with and without TMD, we used analysis of variance (ANOVA) complemented by least significance diference test. Results the vertical dimension of occlusion showed distinct measures in children and adolescents in all age groups studied, significant changes were observed for this measure at ages 10 and 12 years of both genders. Conclusion we can conclude that in this sample there was a direct relationship between TMD and DVO, positive correlation between the measures lip commissure – corner of eye and nasium - mentum in females and significant changes in the vertical dimension of occlusion at the ages of 10 and 12 years for both sexes. .
ABSTRACT
The aim of the present study was to assess the relationship between temporomandibular joint disorder (TMJD) and headache in children and adolescents. A prospective cross-sectional cohort study was carried out involving 93 children and adolescents (6 to 14 years of age) at the outpatient service of a dental school. All participants underwent a clinical examination involving Axis 1 of the Research Diagnostic Criteria for Temporomandibular Disorders, along with a characterization of headache and an anthropometric evaluation. Statistical analysis involved the chi-squared test for quantitative variables and the Student's t-test, ANOVA and Tukey's test for quantitative data. An adjusted logistic regression model was used to determine significant associations among gender, age, TMJD and headache. Mild TMJD was identified in 35.8% of the sample and was not associated the presence of headache. Moderate TMJD was found in 25.8% of patients and severe TMJD was found in 11.8%; both forms of TMJD were associated with headache. A significant correlation was found between the intensity of TMJD and the risk of headache. The present findings demonstrate a positive correlation between TMJD and headache in children and adolescents, independently of gender and age.
