Which statement best describes the PRR technique?

• A. PRR restores with resin composite and uses an overlying fissure sealant
• B. PRR uses only glass ionomer cement
• C. PRR is identical to a traditional Class I restoration
• D. PRR excludes any fissure sealing

Answer: (A)

Preventive Resin Restoration combines a conservative approach to pit-and-fissure caries with both restoration and preventive sealing. The idea is to remove enough decayed tissue to arrest progression, restore the tooth surface with resin composite, and then seal the remaining fissures with a fissure sealant to prevent recurrent decay. This dual action—restoration plus sealing—is the defining feature of PRR. Therefore, the statement that best describes PRR is that it restores with resin composite and uses an overlying fissure sealant. Using only glass ionomer, treating PRR as identical to a traditional Class I restoration, or excluding fissure sealing does not reflect how PRR is intended to work.
