The aim of this extended essay is to investigate and compare the whitening effect of Hydrogen Peroxide and Fluoride on human female teeth. The research question is: “Is there a significant difference between whitening agents Hydrogen Peroxide and Fluoride in terms of their effect on the colour change of human teeth ?” It was hypothesized that there will be a significant difference in terms of their whitening effects of Fluoride and Hyrogen Peroxide on female human incisors. The teeth treated with Hydrogen Peroxide will show a greater color change than the teeth treated with Fluoride. To investigate the whitening effect, a two‐step experiment is planned. In the first step teeth were stained in solutions of coffee, tea and sour cherry juice for 7 days. The second step is the whitening step where the teeth are cleansed with the whitening agents for another 7 days. The color tones at each step are measured using a colorimeter and data analysis is done in order to decide whether there is a statistical difference between the efficiency of the whitening agents. Resultantly, on the enamels of teeth that Hydrogen Peroxide is used, a larger color tone change is observed. The outcome of t‐Test showed there is a significant mean difference between Fluoride and Hydrogen Peroxide in terms of their whitening effects on human incisors.
