The influence of strawberries as bleaching alternative material toward surface microhardness of the teeth is still unknown so that a research should be conducted to quantitatively assess the effects of bleaching with 10% carbamide peroxide and blended strawberry paste on post-extracted incisive teeth by performing superficial microhardness analysis. Three groups of sample i.e. group 1 (control): post-extracted incisive teeth soaked in ordinary mineral water, group 2: soaked in carbamide peroxide 10% gel, and group 3: soaked in 100% strawberry paste. The microhardess of each sample group is tested before and after the application of bleaching materials. The result was there was significant difference of strawberry paste compared to CP 10% gel and mineral water soaked incisive teeth. The data obtained are tabulated, then analyzed with one way Anova and LSD. It can be concluded that the application of carbamide peroxide 10% gel in 6 weeks doesn’t decrease the microhardness of teeth enamel surface. However, the application of strawberry paste decreases the microhardness of enamel surfac
