ABSTRACT

Aim: was to evaluate and compare the effectiveness of two different treatment modalities (arthrocentesis and splint therapy following arthrocentesis) on pain and maximum mouth opening (MMO) of patients with unilateral DDwoR. Material and method: This prospective study was conducted among 80 patients in the Department of Oral & Maxillofacial Surgery, Maulana Azaad Dental College & Hospital. TMJ DDwoR was diagnosed by a history of reduction in mouth opening (unassisted maximum inter-incisal mouth opening <35 mm), mandibular opening with assistance increased by 3 mm over unassisted opening, and TMJ pain during palpation and/or function. Patients assigned to group 1 were treated with arthrocentesis plus sodium hyaluronate injection. Patients assigned to group 2 were treated with a stabilization splint following arthrocentesis plus sodium hyaluronate injection. The statistical analysis was performed using SPSS 22.0 software (SPSS Inc., Chicago, IL, USA). Results: During the subsequent follow-up visits, significant differences were observed in relation to pain between the groups (all P < 0.001). The pain values were similar in groups 1 and 2 at the 1-, 3-, and 6-month follow-up visits with statistically insignificant difference. The MOM values were similar in groups 1 and 2 at the 1-, 3-, and 6-month follow-up visits with statistically insignificant difference. Within-group analyses showed significant improvements in MOM values at all follow-up visits compared to baseline values in both the study groups. Conclusion: The results of the present study concluded that arthrocentesis alone reduces pain whereas arthrocentesis in combination with splint therapy improves MMO more rapidly.
