How can you clean the occlusal surface before placing sealant?

• A. Pumice+prophy cup, explorer & forceful air/water; dry bristle toothbrush, air-polishing with prophy jet
• B. Water only
• C. Brushing with toothpaste
• D. Sanding the occlusal surface

Answer: (A)

The main idea is that you must have a clean and completely dry occlusal enamel surface before placing a sealant so the resin can bond properly. Using pumice with a prophy cup effectively removes the smear layer, plaque, and debris from the fissures. An explorer helps verify that no debris remains, while a forceful air/water rinse clears loosened material and starts the drying process. Following that with a dry bristle toothbrush helps remove residual moisture, and finishing with air-polishing can further clean stubborn deposits and ensure a dry, clean surface. Water alone won’t remove biofilm or the smear layer, brushing with toothpaste can leave residues, and sanding is unnecessary and risks damaging the enamel.
