METHODS: This study was carried out in 17-day-old albino rat pups. The animals were divided into three groups, with eight animals in each group. They were fed on a cariogenic diet (MIT 200) and inoculated with Streptococcus mutans. Group I was given MIT 200 with water, Group II was placed on MIT 200 with black tea, and Group III was placed on MIT 200 with fluoridated water for a period of 45 days. After 45 days, the animals were killed under ether anesthesia, and their teeth were examined for caries.
RESULTS: The carious lesions were scored for the first two molars in each quadrant. In each group, a total of 64 teeth were examined. The caries score between the upper and lower jaws was compared using ANOVA.
CONCLUSIONS: From this study, it may be inferred that drinking black tea reduced the development of dental caries in young rats fed on a cariogenic diet. The tea used for this study was prepared using fluoride-free water, so we can assume that besides fluoride, certain components are present in tea leaves that possess anticariogenic properties.
方法:这项研究是在17天大的白化病幼鼠中进行的。这些动物被分成三组,每组八只动物。他们以致龋饮食(MIT200)喂养,并接种变异链球菌。第一组得到了麻省理工学院200的水,第二组用红茶放在MIT200上,将III组置于含有氟化水的MIT200上45天。45天后,动物在乙醚麻醉下被杀死,检查他们的牙齿是否有龋齿。
结果:对每个象限前两个磨牙的龋齿病变进行评分。在每一组中,共检查了64颗牙齿。使用ANOVA比较上颌和下颌之间的龋齿评分。
结论:从这项研究来看,可以推断,喝红茶可以减少以龋齿饮食喂养的幼鼠龋齿的发展。用于本研究的茶是使用无氟化物的水制备的,所以我们可以假设除了氟化物,某些成分存在于茶叶中,具有防龋特性。
