Abstract
In the discussions on the etiology of the dental caries and periodontal diseases, the relationship between the retention of foodstuffs and the tooth-brushing after meal is often regarded as an important matter.
Now, in order to determine the above mentioned relationship, the estimation of the reducing sugar by the method of Somogyi, the O2-uptake by the manometric method of Warburg and the TTC reduction using Thumberg's tube were carried out, and following results were obtained.
The tooth-brushing after meal, immediately, removes a large amount of retaining foodstuffs, and the O2-uptake effect decreased or the TTC activities of saliva-foodstuff mixture, which were spit out at the same time, reduced.
While, in the same procedure with the exception of the tooth-brushing, the results obtained were the contrary to the above results.
