Comparative Evaluation Of Natural Tooth Whitening Agents - An In vitro Study

Introduction: This study aims to evaluate the colour change in the human enamel bleached with two different natural products and carbamide peroxide, using spectrophotometer. Materials and Methods: Freshly extracted 60 single rooted teeth were obtained. The specimens were divided in to three groups of 20 each: Group 1- Carbamide Peroxide, Group 2- Activated Charcoal, Group 3- Strawberry Puree. These teeth were treated with their respective groups for 20 mins, three times for 1 week. Before and after treatment readings were evaluated. Results: Data were analysed using one way ANOVA followed by Dunnett's T3 post hoc test for intergroup comparison. The results showed that carbamide peroxide was significantly different from activated charcoal (p<0.01) and strawberry puree (p<0.01). Activated charcoal and strawberry puree showed better results in tooth whitening. These natural products can also be used for tooth whitening
