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.
Highlights
The principle of non-invasive remineralizing treatment is more acceptable during the early stages of dental caries disease (Christensen, 2005)
The mean and standard deviation values of enamel and dentin groups are presented in table (1,2) and figure (1,2) respectively
The highest mean value was found in baseline followed by after treatment, while the lowest was found in after demineralization in enamel and dentin groups in the four tested groups
Summary
The principle of non-invasive remineralizing treatment is more acceptable during the early stages of dental caries disease (Christensen, 2005). Phosphate and fluoride ions can produce subspatial remineralization of enamel (Li et al, 2014). It has been well documented that fluoride treatment remains the best remineralizing method for early enamel caries (Ten Cate, 2008). Fluoride lack the ability to guide the formation of mineral crystals and fails to form oriented and ordered mineral crystals on the surface of enamel (Fan, Sun and MoradianOldak, 2009). Chronic ingestion of high doses of fluoride leads to dental fluorosis, skeletal fluorosis in severe cases, where fractures and calcification of ligaments and tendons can occur, leading to reduced joint mobility (Aoun et al, 2018)
