Advanced-PRF: Clinical evaluation in impacted mandibular third molar sockets.

OBJECTIVE: This prospective study evaluated the efficacy and healing potential of modified formulation of PRF, commonly known as Advanced PRF (A-PRF) in impacted mandibular third molar extraction sockets. MATERIALS AND METHODS: 20 patients with bilateral impacted mandibular third molars were included in this study. Surgical disimpactions were done at 3-4 weeks interval in opposing quadrants of patient. One quadrant received A-PRF while the opposing quadrant in same patient was taken as control. Comparative evaluation was done in terms of pain assessment, analgesics required, swelling, soft tissue healing and trismus on 1st, 3 and 7day follow-up. Comparative assessment of bone healing was also done on 1st, 3and 6month follow-up. RESULTS: This study involved 12 female and 8 male patients with in age range of 18-35 years. The evaluation of pain, swelling, trismus and soft tissue healing on 3rd postoperative day revealed considerable improvement on A-PRF sites as compared to control sites. The outcomes were found to be statistically significant with p values 0.008, 0.031, 0.0001, 0.05 respectively. Even the analgesic consumption was remarkably less when A-PRF was used (P=0.004). Bone healing evaluation in A-PRF sites on 1st, 3and 6month has shown significantly improved results with P<0.05. CONCLUSION: Our study infers that A-PRF has enhanced the healing potential of soft tissue as well as bone in extraction socket. Apart from that it has also shown promising results in relief of immediate postoperative symptoms like pain, swelling and trismus which improves the comfort and acceptability of surgical procedures by patients. Enhanced healing and patient comfort in cost effective manner are the highlighting features of A-PRF.
