Many procedures have been developed to try to alleviate the pain and functional complaints of patients suffering from TMJ dysfunctions. The common methods are pharmacologic therapy, occlusal splints, arthroscopic surgery, arthrocentesis and Surgery. The aim of this study was to evaluate effectiveness of arthrocentesis in patients with internal derangement of the temporomandibular Joint. Methodology: 10 patients with complaints of TMJ pain, limited mouth opening, clicking and lateral deviation were treated with arthrocentesis by saline. Pre and postoperative assessment included maximum mouth opening, pain, lateral deviation of jaw and clicking. Results: The results were evaluated comparing pre-procedural, immediate post procedural, and 1st 3rd, 6th 9th months post procedural. After 9 months of follow up, mean improvements were seen in terms of mouth opening, TMJ pain, clicking and lateral deviation which were statistically significant. Conclusion: Arthrocentesis proved to be effective for the treatment of internal derangement of TMJ.
