الملخص EN

Background & Aim : of the research : This study aims at the valuation of the combination of Hyaluronic acid (HA), Platelet-rich Plasma (PRP) injections and TMJ Arthrocentesis in the treatment of Temporomandibular Joint osteoarthritis and comparing it with Hyaluronic acid injection alone.

Material and methods : The sample consisted of 22 patients with TMJ-Osteoarthritis, the sample was divided into two groups,.A+HA+PRP was used in the test group (11 patients) who were treated by TMJ arthrocentesis followed by injection of 0.5 ml of HA and 0.5 ml of PRP.

The reference group (11 patients) who were treated by HA alone.

The injection protocol for both groups was every two weeks for four times.

Pain at rest, pain at mastication, masticatory efficiency, joint sounds, maximum mouth opening, painless mouth opening, functional limitation in the mandibular movement and subjective efficacy were evaluated one month, 3, 6 and 12 months after the last injection in each group separately.

Then the two groups were compared before and after 6 and 12 months.

The radiological changes were evaluated after one year of follow-up by CBCT.

Results : The results showed improvement in the studied variables during the follow-up periods in the two groups with a preference for the participation of A+HA+PRP group in the long follow-up.

Statistically significant differences were found when comparing the two groups after 6 months in all variables and most of which were after 12 months of follow-up, in addition to the superiority of the study group in achieving radial remodeling.

Conclusion : The combination of HA and PRP injections following the TMJ arthrocentesis achieved better improvement than HA injection alone and provided superior clinical and radiological results in the treatment of Temporomandibular Joint osteoarthritis.
