OBJECTIVE: Determine the risk factor involved with developing temporomandibular disorders (TMD) in adolescents. METHODOLOGY: Prospective cohort study carried out on 153 TMD-free adolescents (52.9% women and 47% women). In order to diagnose TMDs the Diagnostic Criteria for Research into TMDs (CDI/TMD), and the CPOD index was used to determine cavities. Two groups were formed: one exposed to dental rehabilitation (74) and one group unexposed (79). Follow-ups were performed two weeks, three months and six months after dental rehabilitation. Descriptive statistics were used and the relative risk was calculated with confidence intervals at 95%. Included in the exposed group were TMDfree adolescents in whom it was necessary to carry out dental rehabilitation treatment on rear teeth with cavities using enamel and dentin to fill in pits and fissures. Included in the unexposed group were adolescents paired with the exposed group based on age and sex, TMD-free and without the need for dental rehabilitation. RESULTS :The incidence of TMD two weeks subsequently in the exposed group (18.9%) was greater in contrast with the unexposed group (5.0%). The relative risk of carrying out TMD on adolescents rehabilitated with resin two weeks after rehabilitation was 2.412 (C.I. 95% 1.001-5.81) times more than in those that did not undergo rehabilitation. CONCLUSION:Dental rehabilitation is a minimum risk factor for carrying out TMD in the short term (two weeks) after the procedure, as this disease induced by rehabilitation is acute and self-limiting.
