The effect of xylitol chewing gums and candies on caries occurrence in children: a systematic review with special reference to caries level at study baseline.

The present findings suggest that the caries-reducing effect of adding xylitol chewing gum to the daily diet has been well demonstrated in children and adolescents with high or moderate caries level at study baseline. Xylitol gum use could benefit subjects with active incipient caries lesions on smooth tooth surfaces.
