AN EXPERIMENTAI EVIDENCE OF CARIES PREVENTIVE ACTIVITY OF NON-FLUORIDE COMPONENT IN TEA

Abstract

Five groups of 20 Wister pure strain rats were fed on the same caries inducing diet 6PMV and excepting one control group, four groups were given drinks of the same fluoride ion strength of 10ppm prepared from NaF solution and tea infusion diluted with 10ppm NaF solution. After 30 days tea drinking resulted in more effective caries reduction than the NaF solution, and the reduction was in inverse proportion to the dilution of the tea infusion, suggesting that it contains many biologically active substances and possesses physicochemical properties for caries prevention.
