Description
ABSTRACT: Studying joint noise is an important parameter for diagnosing temporomandibular dysfunction. In this study, eight groups (n=9) were formed according to joint dysfunction classification, provided by employing vibration analysis equipment. Parameters for analyzing joint noise were: total vibration energy, peak amplitude, and peak frequency. Mouth opening range was also analyzed. Statistical analysis results for each parameter were significant at 1%. Each analyzed group presented different noise characteristics. This allowed for inclusion of the groups within a determined value category. The patient group with normal condyle/disk relationship always presented the lowest values. The type of joint noise was characterized by analyzing total integral noise, peak amplitude, peak frequency, and mouth opening. Analyzing joint noise using electrovibratography suggests the type of joint dysfunction and may help to establish a diagnosis, as well as a treatment plan. Joint noise is an accepted sign of temporomandibular I joint dysfunction (TMD)) (1,2) Some researchers believe that computer analysis, associated with clinical exams and anamnesis, provides better subsidiary information for diagnosis, (3) in view of the fact that electrovibratography can help to classify the type of noise and evaluate severity of joint problems.
