Abstract

Introduction: Sealing Pit and Fissures of occlusal surfaces is one of the most effective dental caries preventive measures, but to do so it needs to have biocompatibility, esthetic appeal and improved mechanical properties like compressive strength, tensile strength and shear bond strength etc.

Aims: To investigate the compressive strength of different Pit and Fissure sealants.

Methods: 10 Standardized restorative material pellets were made from each experimental material namely: CPP-ACP based sealant, GIC based sealant and unfilled resin based sealant which made sample size to be 30. Thermocycline was done to mimic the oral conditions and Compressive strength was evaluated using universal testing machine.

Results: The Compressive strength of GIC based sealant was found to be statistically higher when compared with CPP-ACP and unfilled resin based sealant.

Conclusion: Hence GIC based sealant can be recommended as a stronger and effective pit and fissure sealant in comparison to CPP-ACP based sealant and Unfilled resin based sealant.
