This study aimed to evaluate the transenamel and transdentinal penetration of hydrogen peroxide (H 2 0 2 ) applied to bovine teeth pigmented with black tea at different intensities. The following groups were formed DW: immersion in distilled water; BT100: immersion in an infusion of 1.6 g of black tea per 100 mL distilled water; BT10: immersion in an infusion of 1.6 g black tea per 10 mL distilled water. All groups were immersed for 6 days. To quantify the penetration of H 2 0 2 , the specimens were placed in… Show more
