Abstract

Background: Anterior disc displacement with reduction (ADDWR) is the most common form of the internal derangement (ID) of temporomandibular joint (TMJ). It is a painful progressive dysfunction and clinically characterized by reciprocal clicking due to shift in the disc anteriorly in relation to the condyle and fossa during mandible elevation. Minimally invasive therapy such as intra-articular injection of platelet-rich plasma (PRP) has been used. PRP is a natural autologous product with a high platelet concentration obtained by centrifugation process to enhance tissue healing through several growth factors (GFs), which are released after endogenous activation. The aim of this study is to assess this technique which is increasingly used today as a safe, simple modality.Materials and Methods: sixty patients with ADDWR were participated (Females 41, males 19; age 20-39 years). Patients were divided into two groups; PRP was used as study group and conservative therapy was used as control group. 1 ml of PRP was obtained by a single step centrifugation. Pain, joint sounds and maximum mouth opening were clinically evaluated before and two months after therapy.Results: There was statistically significant improvement in pain score, clicking and maximum mouth opening in patients treated with PRP. No complications were recorded immediately and two months after therapy. Conclusion: This study support the effectiveness of PRP injection in treatment of ADDWR as a safe modality in reducing pain, clicking and increase mouth opening
