OBJECTIVES: This study was aimed to compare the effects of 4 biweekly hyaluronan (HA) injection with glucosamine and diclofenac oral administration on TMJ OA patients.
MATERIALS AND METHODS: This retrospective cohort study included TMJ OA patients who had the treatment of 4 biweekly HA injection (group HA) or oral glucosamine hydrochloride for 3 months and diclofenac sodium for 2 weeks (group G/D), and had complete data at first-visit, 3 months, 6 months, and 12 months. Clinical signs and symptoms were scored by anamnestic dysfunction index (Ai) and clinical dysfunction index (Di), and condylar bone changes were evaluated by CBCT scoring system.
RESULTS: We included 22 patients in group HA and 20 patients in group G/D. After HA injection, Ai was decreased from 4.3 to 1.6(CI [- 4.0, - 1.4]) at 3-month follow-up, which was smaller than that in group G/D significantly. Di in group HA was declined significantly from 8.1 at first-visit to 3.6 at 3-month follow-up, while Di in group G/D scarcely changed until at 6- and 12-month follow-up. Neither HA injection nor oral glucosamine/diclofenac showed positive effect on the bone of TMJs during follow-ups with statistical significance.
CONCLUSIONS: HA injection alleviated signs and symptoms of TMJ OA rapidly and presented superior clinical effects over oral glucosamine with diclofenac. However, both treatments did not limit the bone destruction of TMJs significantly.
CLINICAL RELEVANCE: This cohort study provides knowledge on the symptom relief and bone changes of TMJ OA patients when treated with HA injection or glucosamine and diclofenac oral administration.
