Regular tea drinkers, caries rate is lower. It is generally believed that the anti-caries effect of tea is the role of fluoride in tea [1]. As the tea polyphenols, another major component of tea, have been used to study the effects of cariogenic bacteria and plaque on the oral cavity, the role of tea polyphenols in caries prevention has drawn increasing attention. The purpose of this paper is to provide a scientific basis for the clinical application of tea polyphenols through animal experiments of tea polyphenols against caries. 1 materials and methods distant
