From the rowsThe best-graded row, grade C, is a randomized trial of 485 people (2014) and found an improvement.
The row that found an improvement was larger: 485 people, against 30 people for the row that found no difference.
The row that found an improvement ran longer (3 years) than the row that found no difference (9 weeks).
Only the row that found an improvement names children or teens in its population.
The row that found an improvement is newer (2014) than the row that found no difference (2001).
The best grade is C among the row that found an improvement, and D among the row that found no difference.
The rows
1 improved · 1 no difference- CGrade CDentin cavities in schoolchildren: erythritol vs xylitol and sorbitol candy · Improved
RCT · n 485 · 2014 · First- and second-grade children in southeastern Estonia
About 7.5 g/day of polyol, four candies three times per school day · 3 years
At 24 and 36 months, children on erythritol had fewer dentin cavities and cavity surfaces than those on xylitol or sorbitol, lesions took longer to develop and progress, and caries scores rose less.
- DGrade DPlaque and cavity-causing bacteria with erythritol pastilles · No difference
RCT · n 30 · 2001 · 30 subjects assigned to erythritol or xylitol pastilles (15 per group)
5.2 g/day in five chewing episodes · 2 months
Plaque mass and mutans streptococci fell significantly with xylitol but not with erythritol; neither changed plaque protein or S. sobrinus.
