摘要

Introduction

Temporomandibular joint disorders (TMDs) result in chronic pain & discomfort affecting patient’s livelihood and psychosocial well-being. Internal derangement refers to disruption in the articulating components of the temporomandibular joint (TMJ). Studies have confirmed multifactorial etiology with inflammation in the joint and psychological stress being leading causes. Several surgical and non-surgical techniques have been described for management. This study assesses the efficacy of arthrocentesis & disc repositioning orthotic devices in treatment of internal derangement of TMJ.

Methods

70 patients diagnosed clinically and radiologically with Wilkes stage II and unilateral internal derangement as described by Research and Diagnostic criteria for TMDs (RDC/TMD) in 2014 were included. Patients were subjected to arthrocentesis under local anaesthesia. They were given anterior repositioning hard acrylic splints to be worn for 8 h every night for 2 months. Joint pain, maximal mouth opening & joint sounds were assessed at intervals of (a) Pre-operatively, (b) 1 week post arthrocentesis, (c) 2 weeks, (d) 1 month, (e) 3 months.

Results

Patients reported improvement in pain scores in the first week. Statistically significant improvement was seen in all parameters at 2 weeks interval.

Conclusion

Simultameous arthrocentesis and anterior repositioning splint therapy is effective in alleviating pain and improving mouth opening in patients with unilateral painful internal derangement.
