The Effectiveness of Ultrasound-Guided Temporomandibular Joint Injection in Reduction of Complications Rate Associated With 50% Hypertonic Prolotherapy: Comparative Study

Hypertonic dextrose prolotherapy acts as a regenerative and proliferative material, efficient in stimulating the healing process in the injured joint and diminishing pain associated with functional movement. Ultrasound-guided injection improves the accuracy of injections and reduces the complication rate. Thus, this clinical research worked to evaluate the benefits of the ultrasound-guided injection of 2 mL 50% dextrose in the management of temporomandibular dysfunction cases and to diminish the complication rate. This clinical trial included 50 patients with temporomandibular joint dysfunction. The participants were allocated into 2 groups (blind injection technique and ultrasound-guided injection technique), each group included 25 patients. All cases were treated with a single injection of 2 mL of regenerative hypertonic dextrose 50% solution. Evaluation of cases was done after 1, 2, and 3 months after injection. In this research, the age group
