PRR works best when you can stop caries by sealing a lesion without removing much tooth structure. The ideal candidate is a small, early caries lesion confined to pits and fissures, so the decay hasn’t penetrated deep or cavitated beyond enamel. Intact enamel margins are important because bonding to sound enamel creates a strong, durable seal that prevents microleakage at the margins. Being able to isolate and maintain a clean, dry field is essential for reliableetching, bonding, and placement of the resin. And the whole approach aims for minimal tissue removal to preserve tooth structure and reduce pulp risk, which is particularly important in children. If the decay has progressed into dentin, or if the margins are undermined or isolation is problematic, PRR is not the best choice and a more conventional restoration would be considered.
