Clinical Effectiveness of Biologic Agents as an Adjunct to Non-surgical Periodontal Therapy of Intrabony Defects

The aim of the present study is to clinically and radiographically compare the efficacy of recombinant human platelet-derived growth factor (rhPDGF), Leukocyte-Platelet Rich Fibrin (L-PRF) and Enamel Matrix Derivatives (EMD) in intrabony defects following minimally invasive non surgical peridoontal therapy (MINST). This study will be designed as a randomized clinical trial of 12-month duration. A total of 88 patients (each with a single infrabony defect) will be recruited and randomly equally distributed into 4 groups: an experimental group treated with MINST and rhPDGF, a second group treated with MINST + L-PRF, a third group treated with MINST and EMD and and a control group treated with MINST alone. Each defect will be treated with an ultrasonic scaler with dedicated thin tips for supra- and subgingival debridement associated with hand instrumentation under local anesthesia. Caution will be taken to preserve the stability of soft tissues. Following MINST experimental and control sites will be randomly chosen. The test sites will be treated by inserting a collagen plug soaked for at least 15 minutes in a 1.5cc solution containing hPDGF-BB. In the second group the infrabony defects will be treated with MINST and L-PRF. In the third group the infrabony defects will be treated with MINST and EMD. The control group will be treated with MINST alone. Pre- and post-treatment clinical measurements were performed by an examiner blinded to the treatment modalities using a graded p…
