Arthrocentesis is a symptom-focused treatment for internal derangement of the TMJ. It reduces pain, increases jaw movements and mouth opening, and eliminates inflammatory products and tissue disruptors [Tenoxicam is a potent analgesic and anti-inflammatory agent with a half-life of 60–80 h [Colbert et al. [A few studies have examined intra-articular administration of tenoxicam in patients with internal TMJ derangement [Another study compared intra-articular tenoxicam and sodium hyaluronate in the treatment of internal TMJ derangement and found that there was no statistical difference in recovery [In the present study, the TX group did not have better results than the control group. There was a significant improvement in the parameters of MMO, VAS pain values, ​​and joint-noise values ​​in both groups, but there was no significant difference between the groups. There was no significant difference in both groups in terms of MMO and pain in the first week after the procedure. In the 4th week, there was a significant improvement in MMO in only the control group, while significant improvement was found in both groups at the 12th and 24th weeks. In terms of pain, significant improvement was found in both groups at the 4, 12, and 24 weeks.This study has some limitations. Although the sample size was computed by power analysis, it was limited because only patients with osteoarthritis were included. Another limitation is that the patient follow-up period was 6 months. To our knowledge, this is the first study to evaluate the efficacy of tenoxicam in patients with TMJ-OA.
