Abstract
Aim: To determine the effect of Eugenol based temporary cements on bond strength of RMGIC and RelyX ARC.
Materials and Method: A total of fortymolars were sectioned 3mm below the occlusal surface and roughened surface was smoothened by 60-grit sand paper. Zinc oxide eugenol was given as a temporary restoration for 20 molars and the rest were not exposed to eugenol. Zinc oxide eugenol was removed using ultrasonic scaler and viewed under magnification for precise removal. 20 molars not exposed to eugenol were divided into group 1 (RMGIC) and group 3 (Resin). Other 20 teeth which were exposed to Eugenol were also divided similary into group 2 (Eugenol+RMGIC) and group 4 (Eugenol+Resin). Shear bond strength (SBS) testing was done using knife edge blade in the universal testing machine (INSTRON) at CIPET in Chennai.
Results: On comparing Shear Bond Strength using t-test, no statistical significance (p>0.05) was found between RMGIC groups whereas between Resin groups statistical significance was found.
Conclusion: When ZOE was used as temporary cement there was a decrease in shear bond strength for resin cement but no difference was observed in RMGIC groups.
