A new method for
Preventing Childhood Tooth Decay
Reduces the number of new cavities when used as a partial sugar substitute
A three-year field study on 690 Hungarian school children used a control group with normal diet and oral hygiene, including fluoridated toothpaste. The xylitol group received in addition 20g per day of xylitol in the form of candies. For comparison, the third group received fluoridated milk. The results showed a lower caries increment for the xylitol group than the control and fluoride groups, and indicate that peroral xylitol has a cariostatic effect.

Improves oral hygiene when given as chewing gum after meals
This study compared the effects on dental caries of regular use of sucrose- and xylitol -sweetened chewing gum respectively, in conjunction with a normal diet. After one year, the group using sucrose gum had a mean DMFS increase of 2.92, compared with
an actual decrease in the xylitol group. The xylitol group also had marked reductions in plaque formation and in the count of oral
micro-organisms.

Reduction of caries related to frequency of xylitol use
In the Ylivieska study, 172 children (initially 11-12 years old) used one, two or three xylitol chewing gums daily (maximum dose 10g xylitol/day). In the children who used two and three gums a day, caries reductions of 30% and 60% respectively were achieved compared with 152 subjects who received no gum. In a sub-group with high caries activity, reductions of 50% and 80% were achieved with two and three gums a day.
