Abstract
AbstractObjectivesTo determine the prevalence of temporomandibular disorder and associated factors in an adolescent sample from Recife, Brazil.Materials and MethodsA cross-sectional study was conducted with 1342 adolescents aged 10-17 years. The Research Diagnostic Criteria for Temporomandibular Disorder (RDC/TMD) was used by calibrated examiners to evaluate the presence and levels of chronic pain. To evaluate the socioeconomic conditions, the Brazilian Economic Classification Criteria (CCEB) questionnaire was answered by the subjects. Data were analyzed by means of binary logistic regression in SPSS.ResultsThe results showed that 33.2% of the subjects had TMD irrespective of age (p= 0.137) or economic class (p=0.507). Statistically significant associations were found between TMD and gender (p= 0.020), headache/migraine in the past six months (p=0,000) and the presence of chronic pain (p=0,000). In final model, logistic regression showed that chronic pain contributes to the presence of TMD.ConclusionsThe prevalence of TMD was considered high (33.2%) and adolescents with chronic pain were more likely to have TMD.Clinical RelevanceThe data contribute to the understanding of TMD among adolescents and to the development of preventive measures and polices to identify the dysfunction promptly.
