Background: In dentistry re-establishing, a lost dental esthetic appearance is one of the most important topics. Advances in modern dental materials provide patients with a choice of natural-looking laminates as esthetic restorations. Aim: This study aims to evaluate and compare shear bond strength of direct composite laminate veneer using different surface treatments. Setting and Design: A total of 60 permanent maxillary central incisors were selected for the study. The extracted teeth were thoroughly cleaned and stored in 3% hydrogen peroxide at room temperature for 24 h and then stored in normal saline. Materials and Methods: The facial surfaces of the teeth were prepared to accommodate laminates of equal thickness and were randomly divided into four groups which were allocated to receive different surface treatments. Group A and B included total-etch adhesive system with etching time 15 s and 60 s, respectively, Group C included a self-etch adhesive system with two components and Group D included self-etch adhesive system with single component. After these surface treatments, direct composite laminate veneers were placed on the teeth samples. Later, thermocycling process was carried and final testing was done using universal testing machine. Statistical Analysis: Results were compared with 1-way ANOVA and post hoc Tukey HSD test. Results: The mean shear bond strength was found to be highest for the total-etch method with 60s etching time followed by etching for 15s and the lowest was found to be of self-etch adhesive comprising of a single component. Conclusions: The study concluded that the mean shear bond strength of direct composite laminate veneers using total-etch adhesive system with 60 s etching time was found to be significantly higher compared to other surface treatment methods used in the study.
