AIM AND OBJECTIVE: The aim of this study was to evaluate and compare the effect of various surface treatments on the microtensile bond strength of Lithium disilicate ceramic with dentin.

MATERIALS AND METHODS: A total of 45 human extracted premolars were obtained for the study. The samples were mounted in dental stone blocks having two “V” shaped notch on mesial and distal side of the mounted tooth. The samples were divided into three groups with 15 samples in each. The GROUP-A Control (without any surface treatment), GROUP-B (air abrasion with Al2O3 particles for 15 seconds) and GROUP-C (laser treatment for 5 seconds). Standardize tooth preparation was done on samples and lithium disilicate crowns were fabricated with a loop on occlusal surface. After surface treatment crowns were luted with self adhesive resin cement and pull out load test was performed in universal testing machine.  The data was analysed using one way ANOVA TEST for multiple group comparison followed by Tusky HSD post hoc test. Level of significance was considered at 5% (p-value<0.05).

RESULTS: The surface treatment considerably increased the retention of lithium disilicate crowns. The air abrasion group showed the highest microtensile bond strength values. There was significant difference between air abrasion and laser treatment groups.

CONCLUSION: It was evident that microtensile bond strength was adequately increased after both the surface treatments (air abrasion with Al2O3 particles and laser treatment) and there was significant increase in bond strength with air abrasion with Al2O3 particles group when compared to laser treatment group.
