OBJECTIVE: This study aimed to evaluate the effect of dextrose prolotherapy in treating internal derangement of the temporomandibular joint.

PATIENTS AND METHODS: A total of 20 patients with temporomandibular joint internal derangement were enrolled in the study. The diagnosis of internal derangement was confirmed by magnetic resonance imaging (MRI). The posterior and anterior disc attachment, as well as the most tender part of the masseter muscle, were injected with 12.5% dextrose. Pain, maximum mouth opening, clicking, and deviation were assessed immediately before treatment, as well as at 2-, 4-, and 12- weeks post-treatment.

RESULTS: There was a significant improvement in the four clinical variables at the three-time intervals. Pain at two weeks was reduced by 60% (6 vs. 3.75) and by 200% (6 vs. 1.9) at 4 weeks. The maximum mouth opening was increased by 6.4 mm at 2 weeks and 7.85 mm at 4 weeks.

The percentage of patients with clicking decreased from 70%, preoperatively- to 50% at 2 weeks, 15% at 4 weeks, and 5% at 12 weeks. The ratio of patients with deviation was decreased from 80% preoperatively to 35% at 2 weeks, 15% at 4 weeks, and 5% at 12 weeks.

CONCLUSIONS: Prolotherapy is a safe and effective treatment for alleviating the symptoms of internal derangement of the temporomandibular joint.
