Dental bleaching is among the most sought-after procedures for patients with significant aesthetic concerns. This study evaluated the efficacy of banana peels as a bleaching agent in comparison to conventional gels containing 35% hydrogen peroxide (HP). 15 permanent incisors were randomly divided into 3 groups: GI (placebo), GII (35% HP), and GIII (banana peels). Each underwent three 45-minute bleaching sessions. Color changes (∆E, ∆L, ∆a, and ∆b) were assessed using a visible ultraviolet light spectrophotometer 7 days after each session. Statistical analysis was performed using analysis of variance and Tukey tests, with a significance level set at 5%. The 35% HP-treated group showed higher ∆E and ∆L values and lower ∆b values compared to both the banana peel and control groups. The bleaching effect of banana peels was minimal and not statistically significant (P < 0.61), indicating that they have little or no whitening potential.
