Abstract
Objective
The objective of the present paper is to report results from oral biologic studies carried out in connection with a caries study.
Methods
Samples
of whole-mouth saliva and dental plaque were collected from initially
7- to 8-year-old subjects who participated in a 3-year school-based
programme investigating the effect of the consumption of
polyol-containing candies on caries rates. The subjects were randomized
in three cohorts, consumed erythritol, xylitol, or sorbitol candies. The
daily polyol consumption from the candies was approximately 7.5 g.
Results
A
significant reduction in dental plaque weight from baseline
(p < 0.05) occurred in the erythritol group during almost all
intervention years while no changes were found in xylitol and sorbitol
groups. Usage of polyol candies had no significant or consistent effect
on the levels of plaque protein, glucose, glycerol, or calcium,
determined yearly in connection with caries examinations. After three
years, the plaque of erythritol-receiving subjects contained
significantly (p < 0.05) lower levels of acetic acid and propionic
acid than that of subjects receiving xylitol or sorbitol. Lactic acid
levels partly followed the same pattern. The consumption of erythritol
was generally associated with significantly (p < 0.05) lower counts
of salivary and plaque mutans streptococci compared with the other
groups. There was no change in salivary Lactobacillus levels.
Conclusion
Three-year
consumption of erythritol-containing candies by initially 7- to 8-year
old children was associated with reduced plaque growth, lower levels of
plaque acetic acid and propionic acid, and reduced oral counts of mutans
streptococci compared with the consumption of xylitol or sorbitol
candies.
