Removal of Organic Debris from Occlusal Fissures: Advantage of Carisolv System over Sodium Hypochlorite

The purpose of this in vitro study was to evaluate and compare the removal of artificial debris from pits and fissures using the Carisolv system and sodium hypochlorite. Study design: Forty artificial fissures prepared on extracted human teeth were filled with artificial organic debris. Debris was removed using either Carisolv or 10% sodium hypochlorite gel. After stereoscopic observation, samples were filled with a sealant and subjected to microleakage test. Results: Both Carisolv and sodium hypochlorite demonstrated adequate cleaning ability and prevention of microleakage. Although both Carisolv and 10% sodium hypochlorite are effective at removing debris from fissures, Carisolv presents greater advantages in terms of safety and antibacterial properties. Conclusion: Fissure cleaning using Carisolv might be an effective approach to improve the retention of fissure sealants.
