Preventive Resin Restoration (PRR) combines fissure sealing with what kind of restoration?

• A. A combined approach using fissure sealing and restoration of early proximal caries with minimal tooth structure removal, typically with GIC or resin.
• B. Crown replacement of all posterior teeth.
• C. Root canal therapy is the first option.
• D. Extraction of affected teeth is standard.

Answer: (A)

Preventive Resin Restoration combines two conservative ideas: protect the cracks and grooves with fissure sealing, and address early proximal caries with a small restoration that removes as little tooth structure as possible. This hybrid approach aims to arrest or prevent progression of small proximal lesions while preserving tooth structure, rather than removing large amounts of dentin or performing full-coverage work. The materials chosen are typically glass ionomer cement (GIC) or resin, with GIC being favored in many cases because it releases fluoride, bonds well to dentin, and tolerates moisture during placement. Resin may be used when aesthetics or higher strength is prioritized. This approach is not about crown replacement, root canal therapy, or extraction, which is why the described combination—fissure sealing plus restoration of early proximal caries with minimal tooth structure removal using GIC or resin—is the best fit.
