本文报告了一种含茶饮料的防龋作用。实验组２０４名儿童饮用含茶饮料，对照组１９９名儿童饮用对照饮料，两年后观察其恒牙患龋率和龋均，前者分别为４８．５％，０．８４±１．０５；后者分别为５８．３％及１．２１±１．３２。结果表明饮用含茶饮料两年后，儿童的患龋率和龋均显著降低，提示应用含茶饮料预防儿童龋齿在低氟区可能是一种有前途的防龋方法。
This article reports the anticariogenic activity of a tea-containing beverage. Totally 204 children in the experimental group received tea-containing beverages, and 199 children in the control group took control drinks. Two years later, the caries prevalence and caries of the permanent teeth were observed. The former were 48.5% and 0.84 ± 1.05 respectively. Who were 58.3% and 1.21 ± 1.32, respectively. The results show that drinking tea-containing beverages two years after the children's caries prevalence and caries were significantly reduced, suggesting that the use of tea-containing beverages to prevent dental caries in children in the low fluoride area may be a promising method of caries prevention.
