Our Department of Periodontology, Nihon University School of Dentistry, has been engaged in research on the inhibitory effect of dental plaque by adding chemicals to the chewing-gum popularly consumed by the public.
In the present study, the authors were concerned with the inhibitory effect of chewing-gum to which dextranase was purposely added. As a result of the study, the authors arrived at the following conclusions.
1. As compared with dextranase-containing sugared chewing-gum and sugar chewing-gum with no dextranase, our dextranase non-sugar chewing-gum was found to be inhibitory of the formation of dental plaque with a statistical significance.
2. When sugared chewing-gum was compared with non-sugar chewing-gum, the latter was found to havea higher oral cleaning effect.
However, there was no appreceable difference in the cleaning effect between dextranase-containing sugared chewing-gum, on the one hand, and those containing neither dextranase nor sugar, on the other.
3. No adverse effect was observed in the administration of dextranase-containing chewing-gum at all.
