Purpose: The aim of this study was to find the most effective primary treatment in the patients with disk displacement without reduction associated with osseous changes. Subjects and Methods: The improvement rate during three months after onset of each treatment was compared among the four groups, 1st group, intraoral administration of non steroidal anti inflammartory drug (NSAIDs): 2nd group, NSAIDs and mouth opening exercise: 3rd group, arthrocentesis: 4th group, a combination of arthrocentesis and a single injection of steroid. The subjects analyzed totaled 39 patients consisting of 11 patients in 1st group, 10 in 2nd group, 9 in 3rd group, and 9 in 4th group. Result: The improvement rate was 36.4% in 1st group, 50.0% in 2nd group, 33.3% in 3ed group, and 55.6% in 4th group. Conclusion: In terms of improvement rate, no significance was found among 4 groups. However, “NSAIDs and mouth opening exercise” and “arthrocentesis and a single injection of steroid” could be most appropriate when primary treatment for disk displacement without reduction associated with osseous changes.
