Abstract：
BACKGROUND: The prevention of dental caries has always remained a challenge. Caries prevention through dietary intervention holds promise. Studies have revealed that several constituents present in tea have anticariogenic properties. Tea is a widely consumed beverage and hence could be utilized as a suitable caries preventive agent. The purpose of this study was to determine the effect of black tea on caries progression in experimental animals.
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.

摘要：
背景：预防龋齿一直是一个挑战。通过饮食干预预防龋齿有希望。研究表明，茶中存在的几种成分具有防龋特性。茶是广泛消费的饮料,因此可以用作合适的龋齿预防剂。这项研究的目的是确定红茶对实验动物龋齿进展的影响。
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。
