The occurrence of temporomandibular disorders in subjects presented with dentofacial deformities

Abstract:PURPOSE:to investigate the occurrence of temporomandibular dysfunction in subjects with dentofacial deformity.METHODS:60 subjects of both sexes and aged between 18 and 40 years (mean = 27 years) and formed two groups, one composed of 30 subjects with dentofacial deformity undergoing presurgical orthodontic treatment were evaluated and a control group consisted of 30 individuals with dentofacial balance, paired to dentofacial group, according to gender and age. Anamnestic questionnaire of temporomandibular dysfunction and Axis 1 of Research Diagnostic Criteria for Temporomandibular Disorders were applied, respectively, so as to verify and rate the degree and type of temporomandibular disorders.RESULTS:the results of the questionnaire demonstrated that dentofacial group presented a greater dysfunction degree and score than control group (p <0.01). From the Research Diagnostic Criteria for Temporomandibular Disorders, a greater occurrence of diagnoses involving disc displacement (p = 0.02) and arthritis, arthrosis and arthralgia (p <0.01) for dentofacial group, in relation to control group, was verified.CONCLUSION:individuals with dentofacial deformity had increased incidence of temporomandibular dysfunction, compared with individuals with dentofacial equilibrium, in the sample studied.
