Abstract

Platelets have a very essential role in periodontal regeneration as they are pond of cytokines and growth factors which are the key source for accelerating hard and soft tissue healing. Autologous platelet concentrate i.e. Platelet-rich plasma (1st Generation platelet concentrate) and platelet-rich fibrin (2nd Generation platelet concentrate) are formulated from patient’s own venous blood. Present day studies are being concentrated on the evolution of alternatives which are non-toxic, easy to prepare, biocompatible and cost effective that lead in the local release of growth factors for regeneration and maturation of the bone and soft tissue. PRF is a natural autologous fibrin-based biomaterial derived from an anticoagulant-free venous blood, with no artificial biochemical modifier that ushers to procure fibrin membranes enriched with platelets & growth factors. During centrifugation, slow polymerization forms PRF i.e a fibrin-based structure healing biomaterial better than 1st Generation platelet concentrate and other fibrin adhesives.

Abstract

In oral cavity Pregnancy tumour is an exophytic tissue. It occurs after three months of pregnancy because of vascular effects of hormones during pregnancy. Clinically it appears as sessile or pedunculated exophytic mass, having bleeding tendency. It occurs in response to numerous factors like traumatic injury, low grade irritation, or hormonal changes. For its treatment various modalities are used like flash lamp pulsed dye laser, cryosurgery, Nd: YAG laser, intralesional injection of ethanol, corticosteroids, and sodium tetradecyl sulfate sclerotherapy, but still surgical excision is the treatment of preference. Keywords: Pregnancy, Pyogenic granuloma, Tumour.

Abstract

Periodontal and endodontic tissue structures are closely related odontogenic, which promotes spread of infection. But the desire of patients to maintain their dentition enforce and encourage the dentist to conserve the tooth. In past tooth with severe bone loss and endodontically compromised, resective surgery was employed but today regenerative therapy has potential to restore lost structure esthetically and functionally. In the clinical case presented in this paper, there was bone loss on the site and successful healing was obtained by doing endodontic treatment and using PRF. Keywords: PRF, Root resection, Furcation.
