Aim: To evaluate bleaching efficiency of solutions containing hydrogen peroxide and extract of Pineapple & Papaya as an additive on human enamel in two different timings, using reflectance spectrophotometer Materials and Methods: Baseline color values of 20 randomly selected artificially stained incisors were obtained. The specimens were divided into three groups of 40 teeth each: Group 1 – 30% hydrogen peroxide, Group II – Hydrogen peroxide with Pineapple extract, and Group III –Hydrogen peroxide with Papaya extract. They were further divided into 2 subgroups, according to time of bleaching, i.e. 20 min (Subgroup A) and 10 min (Subgroup B). Statistical Analysis: The results were statistically analysed using using Kruskal Wallis test Results: The mean ΔE values of Group 1A (11.49), Group 2A (12.57), and Group 3A (15.82) showed higher values when compared to the mean Δ E values of Group 1B (10.74), Group 2B (12.21), and Group 3B (15.60). Conclusion: Natural enzymes enhances the bleaching effect when used along with hydrogen peroxide.
