Abstract :
Vital pulp therapy for cariously exposed permanent teeth remains one of the most controversial areas in dentistry. Because a vital pulp is capable of initiating several defence mechanisms to protect the tooth from bacterial invasion, hence it is beneficial to preserve the vitality and health of an exposed pulp rather than replace it with artificial material following pulp exposure. There is no consensus on the survival rate of formerly cariously exposed pulps. Observation time, diagnostic criteria, pulpotomy/pulp capping technique and most importantly, pulpal status at the time of treatment, vary to a great extent amongst studies. In mature teeth, a pulp exposed by caries is usually removed and the root canals are cleaned, shaped and filled. Amongst the methods for preservation of a cariously exposed pulp, direct pulp capping has yielded a markedly high success rate in young teeth. The lack of predictability and long-term success greatly influence decision-making. The decision-making itself is unreliable primarily due to the difficulty of accurately diagnosing the ability of the pulp to repair. While there are various direct pulp capping materials like calcium hydroxide, MTA, Biodentin are considered to be expensive.PRF known to be bodies own tissue being autogenous graft aids in biological healing kinetics. present clinical procedure utilize PRF as direct pulp capping agent which will probably help pulp for repair and regeneration and also considered to be as clinically feasible procedure .
