Effect of Tea on Color Stability of Enamel Lesions Treated with Resin Infiltrant

Abstract

Objectives: This study aimed to assess the effect of tea on color stability of enamel lesions treated with resin infiltrant (RI).
 Materials and Methods: This in vitro, experimental study evaluated 30 extracted human third molars with no caries, cracks, or enamel defects. Enamel-dentin samples measuring 5 x 5 x 3 mm were prepared from the buccal surfaces of the teeth by a microtome. The samples were divided into three groups of 10 namely sound enamel, demineralized enamel, and demineralized enamel plus RI. White spot lesions (WSLs) were artificially created by immersing the samples in hydroxyethyl cellulose demineralizing gel with a pH of 4.5 for 4 days. Next, Icon RI was applied on the samples in group 3. The baseline color of the samples was measured using a spectrophotometer. They were immersed in tea solution 3 times a day, each time for 15 min, for a period of 2 weeks and then underwent colorimetry again. Data were analyzed using one-way ANOVA.
 Results: The maximum color change (∆E) was noted in demineralized enamel plus RI group (38.59±6.13) with significant differences with sound enamel (20.00±2.94) and demineralized enamel (25.27±7.47) groups (P<0.05). The difference between the latter two groups was not significant (P>0.05).
 Conclusion: Within the limitations of this in vitro study, the results showed that tea solution caused clinically unacceptable color change in all groups. However, the color stability of WSLs treated with RI was significantly lower than other groups following immersion in tea solution.

Assessment of Enamel Color Stability of Resins Infiltration Treatment in Human Teeth: A Systematic Review

“…To increase the longevity of resin infiltration in aesthetically relevant areas, patients should avoid consuming colored drinks and foods. In particular, they should avoid the consumption of red wine as, according to some studies [ 9 , 10 , 28 ], it showed the highest average staining value, followed by coffee and tea. Red wine has the highest staining potential due to its alcohol content and low pH.…”

Chemical components of Fu brick tea and its potential preventive effects on metabolic syndrome

“…Nowadays, FBT has become an indispensable drink in northwest China, and there is a saying that “it is better to be without food for three days than without tea for one day” (Emami Arjomand et al., 2021 ; Hayat et al., 2015 ; Xu et al., 2022 ; Zheng et al., 2022 ). In order to further analyze its functional components, the researchers obtained the organic solvent and water extracts of FBT and found that the extracts had various components, including polyphenols, amino acids, organic acids, polysaccharides, and pigments.…”
