The efficacy of injection of sodium hyaluronate in the treatment of patients with disc perforation by using cone- beam computed tomography (CBCT) and temporomandibular joint (TMJ) function.

Treatment of temporomandibular joint disc perforation with injection of hyaluronic acid or disc repair.

Article specifications

This clinical trial was published in 2014 in Journal of Zhonghua Kou Qiang Yi Xue Za Zhi. (IF 2015: 0.12) by Chinese dentists. The aim of this study was to assess the efficacy of injection of sodium hyaluronate in the treatment of patients with disc perforation by using cone- beam computed tomography (CBCT) and temporomandibular joint (TMJ) function. Twenty- eight patients (38 joints) with disc perforation observed through arthrography who received injection of sodium hyaluronate and other 20 patients (29 joints) who received disc repair were included in this study. Pain (visual analog scale, scores 0 to 100), maximal mouth opening, modified Helkimo's clinical dysfunction index and TMJ examinations with CBCT were obtained before and 3, 9 months after treatment.

 

Result

A statistically significant increase in TMJ clinical outcome was observed at each follow-up. Both injection of hyaluronic acid and disc repair are effective for treatment of temporomandibular joint disc perforation.
