Green tea is an antimicrobial agent that has beneficial effects on oral and dental health. The aim of this study was to compare the effect of “green tea” and “green tea with xylitol” mouthwashes on the salivary Streptococcus mutans and Lactobacillus colony count in children.
MATERIALS AND METHODS:
In this double-blind randomized controlled clinical trial, 64 children aged 6-12 years were randomly divided into two groups. Subjects were instructed to wash their mouth with 5% “green tea” or 20% “green tea with xylitol” mouthwashes twice a day for a period of 2 weeks. Salivary counts of bacteria were determined at the baseline and after 2 weeks of intervention.
A significant difference was found between the average number of bacterial colonies between the two groups after intervention (p < 0.001). CONCLUSION: Findings of this study suggest that the effect of the "green tea with xylitol" mouthwash on reducing the number of salivary colonies of S. mutans and Lactobacillus is significantly higher than that of the "green tea" mouthwash. CLINICAL SIGNIFICANCE: The green tea mouthwash can be advised for dental and oral health of children. How to cite this article: Hajiahmadi M, Yegdaneh A, Homayoni A, et al.

Enzymatic production of xylitol is a promising alternative to the chemical hydrogenation process. However, it encounters problems that are largely due to protein susceptibility to environmental factors. In this study, to develop a robust, practical enzymatic process for xylitol production, a coupled enzyme system consisting of formate dehydrogenase (FDH), glucose dehydrogenase (GDH), and xylose reductase (XR) was constructed, wherein the alkaline product produced by FDH and the acidic product produced by GDH could neutralize each other during cofactor regeneration. After optimization of conditions, a pH-neutralization, redox-balanced process was developed that could be carried out in pure water requiring no pH regulation. As a result, a xylitol production of 273.6 g/L that is much higher than those yet reported was obtained from 2 M xylose in 24 h, with a relatively high productivity of 11.4 g/(L h). The strategy demonstrated here can be adapted for the production of other NADH-consuming products.

The aim of this in vitro study was to evaluate the effects of casein phosphopeptides (CPP)-ACPF, NovaMin+ fluoride-containing toothpaste and Xylitol+ fluoride containing cream on demineralized areas on the enamel surface.
MATERIALS AND METHODS:
A total of 100 enamel slab samples was prepared to investigate in the laboratory experiments. For this purpose, a total of 50 freshly extracted third molar teeth which completed root formation split into two portions in the mesiodistal direction. Enamel surfaces were immersed in a pH cycling protocol as described in the literature to simulate oral conditions for 9 days in order to evaluate the effect of test materials on the artificial enamel lesions. Then the remineralization agents were applied on the enamel surfaces, and we analyzed their effects.
We used Vickers Microhardness with the purpose of calculating the amount of lost or acquisition of minerals on the enamel surface qualitatively; inductively coupled plasma atomic emission spectroscopy (ICP-AES) to define the calcium and phosphorus ions that dissolved in acid. One-way ANOVA and Tukey’s T Post-Hoc tests were performed to distinguish significant differences among groups (P < 0.05). CONCLUSIONS: Remineralization was provided in all treated groups, according to the data obtained from all tests. NovaMin was more effective in increasing acid resistance. It was also found that all three experimental groups were effective in increasing the surface hardness, but CPP-ACPF and NovaMin are more effective than Xylitol. However, there was no statistically significant difference between the experimental groups.
