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 masseteric silent period duration was significantly decreased after 4 weeks splint therapy (p<0.01).

저자는 측두하악장애를 가진 환자 15명을 대상으로 교합안정장치 장착 전후의 Helkimo 장애지수 및 교근의 휴지기 지속시간을 측정한 결과 마음과 같은 결론을 얻었다. 측두하악장애를 가진 환자 15명의 실험전 평균 교근휴지기 지속시간은 좌측에서는 50.7msec 우측에서는 50.5msec였다. 교합안정장치를 이용한 4주간의 치료후 평균 교근 휴지기지속시간은 좌측에서는 25.4msec 우측에서는 26.5msec였다. 치료전 Helkimo 기능장애지수와 교근의 휴지기 지속시간과는 상관관계가 높았다.(r : 0.675, p<0.01). Helkimo 기능장애지수는 교합안정장치장착 4주후 현저히 감소하였다. (p<0.01). 교근의 휴지기 지속시간도 교합안정장치장착 4주후 현저히 감소하였다. (p<0.01).
