Comparative Evaluation of Shear Bond Strength of Conventional Type II Glass Ionomer Cement and Triclosan Incorporated Type II Glass Ionomer Cement: An in Vitro Study

Aim: To evaluate shear bond strength of conventional Type II glass ionomer cement with triclosan incorporated Type II glass ionomer cement. Materials and Method: Forty extracted non-carious permanent molars were taken. Triclosan incorporated glass ionomer cement was prepared at a concentration of 2.5%. Specimens were divided into two groups of twenty teeth each. Group A was restored with conventional GIC whereas Group B with triclosan incorporated GIC. Thermocycling was done to simulate oral conditions. After 24 hours Groups A and B were checked for shear bond strength using Instron Universal testing Machine at crosshead speed of 0.5mm/min until fracture. Results were recorded. Results: Data was statistically analyzed by student's t-test. Shear bond strength of triclosan incorporated GIC was higher than conventional GIC. Conclusion: Triclosan incorporated GIC can be considered as an alternative to conventional GIC with enhanced antibacterial property.
