چکیده
The authors declare no conflict of interest. The caries-controlling or preventing effect of xylitol is more than just excluding fermentable sugars from the diet. This review aims to discuss the specific effects of xylitol which could have contributed to the results of the caries trials. Xylitol promotes mineralization by increasing the flow of saliva, an effect it has in common with all sweeteners. What is unique for xylitol is that it is practically non-fermentable by oral bacteria. Xylitol is known to inhibit growth, metabolism, as well as polysaccharide production of mutans streptococci. During habitual xylitol consumption, the counts of mutans streptococci decrease and remain on a lower level as long as the consumption lasts. Habitual xylitol consumption also prevents mother-child transmission of mutans streptococci. In addition to growth inhibition, the reduction of insoluble extracellular polysaccharides is probably of importance for the xylitol-induced decrease in both counts and transmission of mutans streptococci.

Mutans streptococci dose response to xylitol chewing gum.
Xylitol is promoted in caries-preventive strategies, yet its effective dose range is unclear. This study determined the dose-response of mutans streptococci in plaque and unstimulated saliva to xylitol gum. Participants (n = 132) were randomized: controls (G1) (sorbitol/maltitol), or combinations giving xylitol 3.44 g/day (G2), 6.88 g/day (G3), or 10.32 g/day (G4). Groups chewed 3 pellets/4 tim...
متن کاملLinear response of mutans streptococci to increasing frequency of xylitol chewing gum use: a randomized controlled trial [ISRCTN43479664]
BACKGROUND Xylitol is a naturally occurring sugar substitute that has been shown to reduce the level of mutans streptococci in plaque and saliva and to reduce tooth decay. It has been suggested that the degree of reduction is dependent on both the amount and the frequency of xylitol consumption. For xylitol to be successfully and cost-effectively used in public health prevention strategies dosi...
متن کاملThe effect of xylitol chewing gum on mutans streptococci in saliva and dental plaque.
Dental caries are one of the most common infectious diseases occurred in Thai children. The chewing of xylitol, sorbitol, and even sugar gum has been suggested to reduce caries rates. The aim of the present investigation was to evaluate the effect of xylitol chewing gum on mutans streptococci (MS) in saliva and dental plaque. Ninety-one children, aged 10-12 years, with more than 1 x 10(5) MS pe...
متن کاملInfluence of maternal xylitol consumption on acquisition of mutans streptococci by infants.
Xylitol is effective as a non-cariogenic sugar substitute. Habitual xylitol consumption appears to select for mutans streptococci (MS) with impaired adhesion properties, i.e., they shed easily to saliva from plaque. One hundred sixty-nine mother-child pairs participated in a two-year study exploring whether the mothers' xylitol consumption could be used to prevent mother-child transmission of m...
متن کاملImpact of maternal xylitol consumption on mutans streptococci, plaque and caries levels in children.
AIM The present study was designed to determine whether maternal xylitol consumption through regular chewing of xylitol gums can affect the salivary mutans streptococci (MS), dental caries, and dental plaque levels of their children. METHOD Study sample included 60 mother and child pairs with high salivary mutans streptococcus (MS) levels. Samples were randomly divided into experimental group...
