Long-term success of pit and fissure sealants depends largely on their ability to withstand occlusal forces through adequate shear bond strength (SBS). This in-vitro study compared the SBS of three commonly used sealants—Conseal F, Helioseal F, and Smart Seal—applied to extracted primary molars. Using a universal testing machine, shear stress was applied parallel to the bonded interface until failure. Conseal F demonstrated the highest mean SBS, followed by Helioseal F and Smart Seal, with statistically significant differences among the groups.
The findings indicate that material composition and bonding characteristics significantly influence sealant retention, with Conseal F offering superior resistance to masticatory stresses in primary teeth. These results support evidence-based selection of sealants to improve longevity and clinical outcomes in pediatric preventive dentistry. To…
