RESUMO
The aim of this retrospective study was to evaluate the prevalence of signs and symptoms of Temporomandibular Disorders (TMD) and its association in adults, by clinical examination files and questionnaires. This file was composed by one hundred seventy seven volunteers, aged between 19 and 25 years old (mean age 22) selected in The Faculty of Dentistry of Araras from the Hermínio Ometto University Center. They were submitted to clinical examination, computerized eletrovibratography and answered a questionnaire. The volunteers were classified according to the presence of TMD tenderness and/or articular noises in TMD or not TMD subjects. The data were submitted to statistical analysis in order to verify the association between TMD and the presence of (1) occlusal interferences, (2) bruxism, (3) articular hypermobility, (4) articular noises and (5) presence of orthodontic treatment. It was verified that of the 177 volunteers, 101 have not presented any signs of TMD and 76 were classified as TMD patients. The Chi square test and Fisher´s Exact test demonstrated a TMD prevalence of 42.94 % at 95% of confidence level (lower limit of 35,54% and higher limit of 50,58%). It was verified a significant association (p<0.0001) between TMD and articular noises, and between TMD and bruxism (p<0.05). There was no association between TMD and other variables: occlusal interferences (p=0.929), articular hypermobility (p=0.081) and orthodontic treatment (p=0.103). These data suggests that patients presenting bruxism should be monitored regarding to TMD occurrence.
