Objectives: Erosive tooth wear is a common worldwide problem. It manifests due to consumption of high caloric and low pH acidic drinks such as carbonated soft drinks and fruit juices, which cause irreversible damage to dental hard tissues. The aim of this study was to evaluate the effect of Chinese green tea on surface characteristics of eroded enamel in an in-vitro erosion model. Materials and methods: Twenty sound extracted human premolars were selected. Micro-hardness and surface roughness were measured before conducting the experimental test to serve as raw data (control), after immersion in Coca-Cola with a pH of 2.8 for 1 hour, 3 times a day for 3 days and then after immersion in green Chinese tea solution for 1 hour 3 times a day for 3 days. The surface micro-hardness was measured using Vicker's diamond under a load of 50 grams for 15 seconds while the surface roughness was measured using Taly-surf. Results: The data were analysed using paired t-test. The micro-hardness measurements obtained before green tea treatment (Mean=102.46, SD=24.82) were significantly lower than those which were obtained after green tea treatment (Mean=158.9, SD=41.44), p=0.0001. The roughness measurements obtained before green tea treatment (Mean=7.34, SD=1.76) were significantly higher than those which were obtained after green tea treatment (Mean=5.14, SD=1.8), p=0.0001. Conclusion: Chinese green tea positively affected the surface characteristics of eroded enamel.

“…36 Green tea has many beneficial properties for the treatment of cardiac diseases and obesity. 16,17 Anticarcinogenic properties of green tea have also been confirmed. [36][37][38] Since EGCG is the most active component of green tea extract, 39 it was used as the green tea extract in our study.…”

“…The anticariogenic mechanisms of green tea have been partly understood. [16][17][18] Duration of exposure of tooth structure to green tea affects its cariostatic efficacy. Thus, to benefit from its cariostatic effects, green tea must be used in a form with maximum durability on the tooth surface.…”

Aim: Root caries is a common, debilitating condition particularly in the elderly population, which can lead to tooth loss. Evidence shows that green tea has cariostatic effects. Considering the gap of information on green tea varnish, this study aimed to assess the efficacy of green tea varnish in the prevention of root caries. Materials and methods:This in vitro experimental study was performed on 42 sound premolars. Two layers of acid-resistant nail varnish were applied on root surfaces except for a window of 1 × 4 mm. The teeth were randomly divided into three groups (n = 14). Group I (control) received no intervention. Group II received green tea varnish applied on the roots every 48 hours for 21 days. Group III received green tea varnish every 24 hours for 21 days. Sections of 40 µ thickness were prepared from the center of the window, and the depth of carious lesion was measured in three points with 500 µ distance from each other using polarized light microscope. Data were analyzed using Statistical Package for the Social Sciences (SPSS) version 16 and nonparametric Kruskal-Wallis and Mann-Whitney U tests (α = 0.05). Results:The mean (and standard deviation) depth of carious lesion was 54.30 ± 28.64 (µm), 0, and 0 in groups I, II, and III respectively. Control group showed the highest depth of caries. Groups II and III were not significantly different in this respect, but significant differences were noted in depth of caries between groups I and II and also groups I and III (p < 0.001). Clinical significance: Application of green tea varnish can prevent root caries. Conclusion

“…The increase in surface microhardness values after immersion in green tea solution reveals an improvement in the demineralized structure of eroded dentin. 22 After immersion in green tea, there are obvious deposits on the dentin surface and conversion into a more organized, feature is detected on SEM evaluation. 2 Preservation of dentin matrix by MMP inhibition might be another probable explanation for these observations.…”

The aim of this in vitro study was to analyze the effect of green tea on the hardness of eroded dentin. MATERIALS AND METHODS 40 extracted sound human premolars with premeasured hardness values were immersed in Coke for five minutes and then immersed in a green tea solution for five minutes. The surface hardness was remeasured with a Vickers diamond under a load of 500g/10s immediately after each immersion. All hardness values were compared with pretreatment values by the Wilcoxon test. RESULTS The mean ± SD of hardness values before and after insertion in coke was 48.12 ± 1.69 and 45.47 ± 1.55 respectively. The hardness values after immersion in green tea were and 54.32 ± 2.17 with statistically significant differences between the two measurements. Thus, green tea aided in the repair of the eroded dentine by increasing its hardness. CONCLUSION Aerated acidic beverages cause dentinal erosion and decreased surface hardness. Green tea is a healthy beverage with many medicinal effects that increase the hardness of dentin, thus forestalling erosion. Therefore, the consumption of green tea is the most easy, simple and non-expensive method to intercept and treat dentinal erosion and should be promoted.
