Efficacy of the Entire Papilla Preservation Technique With and Without the Use of L-PRF as a Regenerative Material for the Treatment of Infrabony Defects

The Entire Papilla Preservation Technique (EPP) is a minimally invasive surgical approach for the treatment of intraosseous defects allowing access to the defect maintaining the integrity of the interproximal papilla. Studies have evaluated its efficacy for the regeneration of intraosseous periodontal defects with or without the use of regenerative biomaterials to fill the defect.

L-PRF is an autologous concentrate of platelet- and leukocyte-rich fibrin derived from blood, which through a centrifugation process allows to stimulate, improve and accelerate healing. The growth factors in the concentrates, together with pro-inflammatory and anti-inflammatory molecules, actively participate in the stimulation of the processes associated with tissue and bone repair and regeneration. Due to its high content of fibrin, platelets, leukocytes, monocytes and stem cells, L-PRF acts in immune regulation by controlling inflammation, with a continuous release of growth factors and presents an analgesic effect, which gives greater postoperative comfort to the patient. In addition, being an autologous product, it greatly reduces the risk of infection or rejection by the patient. Due to its beneficial biological effects, low costs and ease of preparation its use as a filling material in intraosseous defects will be evaluated.
