PRR stands for which term in conservative dentistry?

• A. Preventive Resin Restoration
• B. Proximal Resin Restoration
• C. Partial Resin Repair
• D. Pulpal Resin Reinforcement

Answer: (A)

Preventive Resin Restoration is a minimally invasive technique used in conservative dentistry. It combines sealing of pits and fissures with a resin-based sealant and a resin restoration for adjacent proximal lesions, all in a way that arrests caries progression while preserving as much healthy tooth structure as possible. This approach targets early or limited caries by preventing further decay under a bonded seal and restoring function with resin, rather than removing large amounts of tooth structure.

That's why Preventive Resin Restoration is the best choice here. The other terms aren’t the standard designation for this combined preventive-and-restorative approach—proximal resin restoration isn’t the recognized name for the technique, and partial resin repair or pulpal resin reinforcement refer to different concepts altogether.
