Vibrations in the temporomandibular joints in patients examined and treated in a private clinic.

Patients indicated for examination, evaluation and treatment of the temporomandibular joint (TMJ) in the Centro de Diagnostico e Tratamento da ATM (CDTATM) were submitted to computerized BioPAK system tests. Special attention was placed on the SonoPAK test (electrovibratography), seeking to evaluate the articular sound problem in differentiated patients for specific TMJ treatment. The percentage of sounds (148 joints, 74 patients) was high (75.67% in the opening movement and 50.00% in the closing movement) which suggests the necessity to give more attention to the TMJ sounds during a clinical exam. And also, if possible, give more attention to the utilization of specific tests to obtain a clear definition of the type of sound the patient presents.
