Tissue engineering in Oral & Maxillofacial surgery.

A recent innovation in dentistry is the preparation and use of platelet rich plasma, a concentration of platelets and growth factors found in platelets. These polypeptide growth factors as well as other bioactive substances are released from platelets upon activation, which play a pivotal role in initiating and sustaining wound healing and tissue repair mechanism. In order to improve wound healing and bone regeneration, attempts were made to increase the concentration of wound healing initiating factors in the form of platelet concentrate. Platelet derived polypeptide growth factors as well as other bioactive substances are released from platelet upon activation which plays a pivotal role in initiating and sustaining wound healing and tissue repair mechanism. This article is an attempt to highlight the uses of Platelet rich plasma (PRP) in Oral & Maxillofacial Surgery and the preparation of PRP gel in the immediate preoperative period in a laboratory centrifuge.
