Abstract

|
|
The purpose of this study was to investigate the reliability of electromyographic examination in a day and detect the objective measurement timing of electromyography.
18 normal students who were in dental collage of C national university were selected for this study. They had no symptoms on temporomandibular joint area, no restorations and missing tooth on dentition. Their molar relationship was normal or class I of Angle´s classification. Electromyograph had been taken every one hour from 9 : 00 A.M. to 5 : 00 P.M. in the state of clenching and rest by using Bioelectric processor EM2 interfaced with mandibular kinesiograph K-6 diagnostic system. We compared and analyzed the variances of electromyograph values of each subjects.
The obtained results were as follows
There were no significant differences on variability of electromyograph values in each state clenching and rest. In the aspect of this circumstances, the use of electromygraphy could be a good objective procedure to diagnose the temporomandibular disorders and to detect the effect to the treatment of temporomandibular disorders at any time in a day from 9 : 00 A.M. to 5 : 00 P.M.
