... JPDS Patients who were unresponsive to conservative treatment were included in this study. The study consisted of a single arthrocentesis procedure performed by a single oral surgeon per patient. Visual Analogue Scale was used to record pain while maximum mouth opening was measured by the interincisal distance in millimetres, at 1 month and 2 months after the treatment. Success was measured two months after arthrocentesis. Thirty (66.7%) patients had no pain and 15 (33.3%) patients had mild pain. Similarly, 16 (35.5%) patients had maximum mouth opening more than 30mm and 29 (64.5%) patients had less than 30 mm mouth opening, two months after arthrocentesis procedure. Arthrocentesis is very effective in patients suffering from TMPDS by reducing pain and discomfort and increase in mouth opening. This procedure should be considered in TMPDS patients who do not respond to conservative treatment.
