This study was performed to compare the TMJ sounds by means of vibration-related items by Sonopak such as integral, high integral, above 300/(0-300) ratio, peak amplitude, peak frequency and median frequency before and after occlusal splint therapy as well as counselling, physical modalities.
For this study 22 patients with craniomandibular disorders (CMDs) were selected and examined by routine diagnostic procedure for CMDs including Transcrarual and Panoramic radiographs and were classified into 3 CMDs subgroups :disc displacement with reduction, disc displacement without -reduction, and degenerative joint disease.
Visual analogue scale WAS) about joint,saund was recorded during treatirnent period and VAS treatment index (VAS Ti) was calculated from the VAS data and=treatment duration. The author evaluated and compared treatment, .results by several parameters such as symptom duration, timing of joint sound, parafu nctional habits, trauma, and diagnostic´ classification.

The obtained results were as follows

1. Before the treatment, the highest value of peak amplitude was observed in disc displacement with reduction group and value of median frequency was highest in degenerative joint disease group. In addition the highest values of peak frequency and ratio were observed in degenerative joint disease group, though they were not significant Furthermore the lowest value of high integral was observed in disc displacement without reduction group and though it was not significant, value of integral was lowest in that group.
2. Among 3CMDs subgroups disc displacement with reduction group showed the significantly decreased value of high integral and degenerative joint disease group had the significantly decreased value of integral after conservative treatment including occlusal splint therapy. Conclusively conservative treatment including occlusal splint therapy may be effective in the treatment of CMDs including TMJ sound.
3. Fair prognosis for conservative treatment was observed in acute group under 6 months than chronic group, 6 months over in symptom duration but there was no statistical difference. The result for conservative treatment was observed slightly poor in subjects with bruxism, clenching, unilateral chewing habit and trauma history but there were no statistical differences.
