Interventions
This is a triple-blind, three-arm, randomized controlled clinical trial involving 51 participants, who were randomly allocated into three intervention groups (n = 17 per group). The participants were
Group B: 10% carbamide peroxide vs. 20% carbamide peroxide
and Group C: 15% carbamide peroxide vs. 20% carbamide peroxide. Randomization was performed by drawing coded tokens from an unmarked container. The participants were unaware of the concentrations used
