Abstract
The purpose of this study was to choose the types of the TMJ dysfunction syndrome which were able to be polarized light therapy (SUPER LIZER). The subjects were 14 Patients (13 females and one male, mean age was 16 years 6 months). We divided them into the following to groups.
Effective group; 7 patients who were cured of TMJ pain after SUPER LIZER therapy.
Non-effective group; 7 patients who remained with TMJ pan after SUPER LIZER therapy.
We compared MR imagings and clinical signs before treatment between both groups. The results were as follows.
1. The prevalence of joint effusion in the non-effective group was statistically higher than that of the effective group, although the prevalence of anterior disk displacement showed no difference between the two groups.
2. The interincisal distance of the maximum opening in the effective group was significantly larger than that in the non-effective group. In the effective group, the contraction term of the TMJ pain had a tendency to be longer compared with the non-effective group.
