Aim: The purpose of this study was to compare the element content in enamel surface before and after bleaching with two different bleaching agents using three modes of activation. Materials and Methods: Thirty human extracted central incisors were randomly divided into two groups based on the bleaching agents and were further subdivided into three subgroups based on the mode of activation as follows. The crowns of the teeth were demarcated into two halves vertically; one half serving as control while the other half is the bleached surface. Following bleaching, the samples are to be subjected to elemental analysis using EDAX software. Results : Using analysis of variance (ANOVA) tests it can be concluded that despite different bleaching agents with different concentration used, there was no overall significant difference between the element content before and after bleaching. Conclusion: Lasers showed a better performance than halogen light cure unit in terms of surface effects and elemental content.
