Abstract

To determine the effects of 10% and 15% carbamide peroxide on extrinsic enamel discoloration caused by black tea. Thirty-two extracted human premolars randomly divided into two groups were soaked in a black tea solution for eight days, then mounted in microwax. The specimens were subjected to 14 applications of bleach, each of seven-hour duration. Color changes after the 7th and 14th applications were measured using the CIE L∗a∗b∗ method with VITA Easyshade®. Independent t-tests showed no significant difference in the color change value between groups. The data showed there was no difference in the effectiveness of bleaching using 10% or 15% carbamide peroxide on extrinsic enamel discoloration caused by black tea.
