Abstract
The purpose of this study was to evaluate the effect of occlusal splint on the electromyographic silent period duration of masseter muscle in patients with TM disorders.
The author measured the Helkimo dysfunction index and masseteric silent period duration before and after 4 weeks splint therapy in 15 patients with TM disorders.
The results were as follow:
Before splint therapy, the mean durations of masseteric silent period in 15 patients with TM disorders were 50.7msec in left and 50.5msec in right.
After 4 weeks splint therapy, the mean durations of masseteric silent period were 25.4msec in left and 26.5msec in right.
In the correlation between Helkimo dysfunction index and masseteric silent period duration in before treatment, correlation coefficient is 0.675, p. < 0.01. There is statistically significant correlation between Helkimo dysfunction index and masseteric silent period duration.
Helkimo dysfunction index was significantly decreased after 4 weeks splint therapy (P < 0.01)
The masseterlc silent period duration was significantly decreased after 4 weeks splint therapy. (p < 0.01).
