Abstract
Aim
To evaluate the effect of xylitol-containing tablets on mutans streptococci colonisation and caries development in preschool children.Study design
Randomised single-blind prospective design.Methods
The material consisted of 132 healthy 2-year-old children, 71 boys and 61 girls and they were assigned to a xylitol tablet (test) group or a non-intervention control group. The mean age was 2 years + 1 month in both groups. The drop-out rate was 10.6% during the 2-year trial. The test group was given 1-2 xylitol tablets (0.5-1g) per day during 1.5 years. Mutans streptococci (MS) enumeration was performed at baseline and semi-annually in the children and at baseline or shortly after in the mothers with a chair-side technique. Caries prevalence was scored at baseline and the age of 4 years.Results
No statistically significant differences in MS colonisation were disclosed between the test and control groups at baseline or any of the designated follow-ups. A statistically significant positive relationship was found between the maternal salivary MS levels and the colonisation of the children in the control group at 2.5 years, 3 years and 3.5 years (r=0.39, r=0.35; r=0.30; pConclusion
The findings do not support a low-dose xylitol tablet program for caries prevention in preschool children.
