In groups B, C and D, 35% hydrogen peroxide was applied on the teeth for 20 minutes and rinsed. This process was repeated two more times. The teeth were etched with 35% phosphoric acid for 15 seconds and rinsed for 15 seconds. A microhybrid composite was applied in Tygon tubes, bonded to the teeth with single Bond, and light-cured. Mode of failure was also determined. SBS was measured by a universal testing machine and data were analyzed by one-way ANOVA and Tukey’s test. </span></span></span></span><br>
