Adolescents between 10 and 20 years of age and enrolled in a municipal school system.

Detailed Description:

For the assessment of signs and symptoms of TMD and parafunctional habits, 244 adolescents between 10 and 20 years of age and enrolled in a municipal school system were analyzed. The participants were submitted to the self-explanatory questionnaire for screening recommended by the American Academy of Orofacial Pain for the determination of orofacial pain and TMD. This questionnaire is made up of ten guided questions with yes or no responses to the most frequent signs and symptoms of orofacial pain and TMD. According to the Academy, three or more affirmative responses are an indication of TMD. Patient history and a detailed clinical exam were performed for the assessment of the presence or absence of parafunctional habits.

The frequency of signs and symptoms was analyzed and the data were described based on gender and age. The SPSS 12.0 program was used for the statistical analysis and the data were treated using the chi-square test.
