Recent Advances in Preventive Resin Restoration (PRR)

Abstract

Aim and objective: to review about the recent advances in preventive resin restoration. Background: Preventive resin restoration (PRR) is a thin, resin coating applied to the chewing surface of molars, premolars and any deep grooves of the teeth. It consists of an enamel sealant with a resin filling. If caries is present in one area or parts of pits and fissures, that particular area of caries is restored and fissures are protected with sealants. Reasons for review: Newer materials and techniques may help in reducing the risk of early failure in difficult to seal teeth and to also improve the retentiveness and strength of the material.
