Effect of the Maltitol-Gums on plaque pH

Objective To determine the impact of Maltitol-Gums on Plaque pH.Methods Thirty 13～15 years old children with DMFS 4 were divided into three groups randomly: maltitol chewing gums group(group A),xylitol chewing gum group(group B) and blank gum base group(group C).The dental plaque pH was measured in situ by Beetrode microelectrode methods.Results The pH responses in the plaque after chewing three different gums showed a rising response,20 min at highest.After chewing gum for 4w,the pH was a significant different compared with before chewing gum(P0.05).After chewing gum for 4w,the differences of △pH among different chewing gum were significant differences.Conclusion Maltitol-Gums can lead to the same significant effect on plaque pH as Xylitol-Gums.
