Introduction: Disc derangement disorders of the Tempromandibular joint (TMJ) are a group of intra-articular biomechanical disorders in which there is an abnormal relationship in the functional ‘articular cartilaginous’ condyle-disc complex. Arthrocentesis is a valuable effective non-invasive treatment option of many internal derangement cases. Adding benefit to arthrocentesis outcome through the use of platelet rich plasma (PRP) is a point of research taking benefit from growth factors to enhance tissue healing.
Objectives: the present study aims to compare the clinical outcome of the use of arthrocentesis alone and arthrocentesis +PRP in management of TMJ internal derangement.
Materials and Methods: Fourteen patients with disk displacement without reduction (DDwOR) were included in the study diagnosed according to The Research Diagnostic Criteria for Tempromandibular disorders (RDC/TMD). Cases are randomly allocated into two groups as follow; seven patients underwent intra-articular injections of 2 ml PRP after arthrocentesis (study group) and the other seven patients were treated by the conventional arthrocentesis using Ringer’s solution (control group). The patients were clinically evaluated preoperatively and postoperatively at the intervals of 1 month and 6 months.
Results: there was no statistically significant difference between two groups in all the measured parameters were throughout the postoperative period. However both groups showed statistically significant improvement regarding mouth opening and joint pain.
Conclusion: arthrocentesis either alone or with PRP injection is a safe and effective method in the treatment of TMDs.
