Introduction: The Temporomandibular Joint Disorders (TMJ Disorders) has very ample interpretation and describes a population of patients suffering from muscles dysfunctions and the muscles and toggles of jaw usually painful 1. Beyond the complaints of pain in the cheek, ear pain and migraines the patients with these clutters many times have limited or anti-symmetrical jaw movements, and the sounds of the TMJ most described as "clicks". Aim: With intention to make qualitative and quantitative analysis of the use and acuracity of an instrument of diagnostic aid, we used the "Questionnaire for Selection for Orofacial Pain and TMJ Disorders", recommended for the American Academy of Orofacial Pain (attachment 1), not yet tested in Brazil. The target population was made of patients with complaints of dental pain in the orofacial region, chronic headache, ear ache and daily pain in the preauricular area or in the TMJ, that made they seek for medical and dental attention at the CSS/CECOM, an ambulatory that the Unicamp keeps for the attendance of its internal community. Study design: Prospective clinical randomized. Method: The questionnaire was applied to 46 patients (40 women and 6 men), with later a specific clinical examination that resulted diagnosis of TMJ Disorders. Results: The statistical analysis disclosed that this questionnaire presents a sensitivity of 85,37% and a specificity of 80% for carrying patients of muscular symptoms of the orofacial region (Kappa = 0.454) and a low sensitivity and specificity for articulate symptoms (Kappa = 0.043). Conclusion: The questionnaire is useful and viable for a daily selection of TMJ Disorders, mainly for the myogenic riots, but shouldn’t be use as the only tool for diagnosis
