To investigate the inhibitory effect of erythritol and xylitol, which are sugar substitutes, on growth of major caries-inducing bacteria, Streptococcus mutans and Lactobacillus casei and dental plaque formation, the saliva was collected after application of sterilized water, sugar, erythritol and xylitol solutions, the experimental results are as follows. 1. Xylitol was found to be the substitute for sugar, which can effectively block the growth of S. mutans and L. bacillus in the oral cavity. The erythritol showed a lower effect than the xylitol. In case of S. mutans, high growth was observed after application of sugar solution but decreased when erythritol and xylitol were applied. In the case of L. casei, the degree of growth was significantly increased when the sugar solution was applied compared to S. mutans . Therefore, it was confirmed that it was more sensitive to the sugar solution. And decreased with the application of erythritol and xylitol. 2. Xylitol can reduce the growth of general oral microorganisms most effectively, and erythritol is also effective in reducing general oral microorganisms. 3. Xylitol is a substitute for sugar that can effectively reduce the adhesion rate of dental plaque on the tooth surface, and that erythritol has a slight effect. Thus, it is considered that the erythritol and xylitol have a sufficient value as a substitute for sugar that has caries preventive effects, because erythritol and xylitol reduce the number of oral bacteria including S. mutans and L. casei and inhibit the formation of dental plaque.
