Abstract
The flexural strength of dentin and the rate at which dentin collagen degrades are two important variables that affect how long restorative dental materials last. The use of natural extracts to improve the qualities of dental materials has been studied recently. The antioxidant-rich white tea extract has the potential to be beneficial when mixed with calcium silicate cements. This in vitro research used forty removed human molar teeth. After the teeth were sectioned to obtain dentin specimens, the dentin was randomly divided into four groups (n=10) according to the type of treatment: Group A (control) consisted of the dentin that had not been treated; Group B treated the dentin using conventional calcium silicate cement; Group C treated the dentin using calcium silicate cement combined with 5% white tea extract; and Group D treated the dentin using calcium silicate cement combined with 10% white tea extract. A universal testing apparatus was used to measure flexural strength, and hydroxy-proline release analysis was used to measure collagen degradation during a 30-day period. ANOVA and post-hoc tests were used to examine the data, with a significance level of p < 0.05.Incorporating white tea extract into calcium silicate cements improves the flexural strength and lowers collagen degradation of dentin. The benefits are more noticeable with larger concentrations of extract.
