Abstract

Background: Glass Ionomer cements (GIC) are being used routinely in Restorative Dentistry. Adding Chlorhexidine (CHX) to GIC may enhance their antibacterial property, which may affect their bond to dentin. Aim: To evaluate the influence of incorporating chlorhexidine hexametaphosphate nanoparticles {CHX-HMP} to Type II GIC on the microshear bond strength to dentin at 24 hours and 7 days. Methodology: Cylindrical moulds, placed on flat dentin surfaces of human molar teeth were filled with Type II GIC containing nanoparticles of Chlorhexidine hexametaphosphate (CHX-HMP). Cylindrical molds filled with Type II GIC served as control. The samples were kept at 37 °C and 100% humidity for 24 hours and subjected to microshear testing. Microshear bond strength was determined using Universal Testing machine at 24 hours and 7 days. Results: Microshear bond strength in Conventional GIC increased from a mean of 2.19 Mpa at 24 hours to 3.11 Mpa on 7th day. Microshear bond strength of GIC with Chlorhexidine did not increase significantly ie. 3.28 Mpa at 24 hours to 3.35 Mpa at 7th day. There was a significant difference in microshear bond strength at 24 hours between GIC and GIC-CHXHMP. Conclusion: The addition of CHX in the concentration of 2% did not negatively influence the bond strength of Type II GIC to dentin.
