Evaluates the effects of dentin modifiers on shear bond strength and microleakage in caries-affected dentin, suggesting effective treatment approaches.
AIMS: Assessment of the impact of different dentin bio-modifiers i.e., Bromelain, Riboflavin photosensitizer (RFP/Ultraviolet-A), and Chitosan nanoparticles (CHNPs) on the shear bond strength (SBS) and microleakage of composite bonded to acid etched carious affected dentin (CAD). MATERIALS AND METHODS: However, Group 1 (No modifier) exhibited the lowest resin tag length (50.45 ± 2.37 μm). CONCLUSION: Caries-affected dentin modified with Bromelain resulted in satisfactory SBS with minimal microleakage scores. Chitosan nanoparticles and RFP/Ultraviolet-A also presented better outcomes in terms of microleakage and SBS than the control.
