Effect of Green Tea, Black Tea and Moringa Oleifera on Remineralization of Artificially Demineralized Enamel and Dentin: An In-vitro Microhardness Analysis.

Abstract

Objectives: The present in vitro study aimed to investigate and compare the effect of green tea, black tea and Moringa Oleifera on artificially demineralized enamel and dentin. Methods: Forty intact maxillary molar teeth were sectioned mesiodistally. The demineralized samples of enamel and dentin were randomly divided into four subgroups according to the treatment utilized. Group 1: Green tea extract; Group 2: Black tea extract; Group 3: Moringa Oleifera extract and Group 4: Artificial saliva (control). The samples were subsequently evaluated using microhardness tester. Data were tabulated and statistically analyzed using ANOVA and t-test. Results: A statistically significant difference was found between baselines followed by after treatment, while the lowest mean value was found in after demineralization. A statistically non-significant difference was found between the four tested groups in enamel samples. In dentin, the highest mean value was found in Moringa Oleifera while the lowest mean value was found in black tea. The highest percentage of change was found in Dentin showed higher percentage of change after treatment compared to enamel. Conclusion: Black tea, green tea and Moringa Oleifera enhanced the remineralization process of demineralized enamel and dentin, and thus, might be considered as an effective natural remineralizing agents.
