A Study on the Masticatory Form and Regional Difference by Masticatory Jelly in Chinese Children

Abstract

This study was carried out to evaluate the masticatory function and for the investigation of the relationship to dental diseases and masticatory function by use of biting of three types of masticatory jellies for modern Chinese children in Beijing, Leshan and Hong Kong.
For evaluation of the masticatory function, the masticatory time and masticatory cycles were recorded for each jelly mastication with individual children.
As the results;
1. There was no obvious relationship to the masticatory function in the children,1010with no caries and with severe caries.
2. The masticatory function was not affected by the taste.
3. There was no obvious relationship to the masticatory function in the children, with normal and with malocclusion.
4. It seemed that the infants (3 years,6 years) in Leshan showed the most massive masticatory efficiency compared with in Beijing and Hong Kong.
