Abstract

The author extracted 300 children as a control group and 300 children as an observation group from Korean primary school children which were aged 9 to 11, and surveyed the dental caries experience and oral hygiene condition. Children in a control group had not been served wit school meal. On the other hand, children in an observation group were served with school meal. The average number of caries experienced permanent teeth per mouth and the oral hygiene indices were calculated from the collected data and compared with each other. The obtained results were as follows. 1. The DMFT rate was 15.93% in the observation group and 10.33% in the control group. 2. The Oral Hygiene Index was 1.04 in the observation group and 1.60 in the control group. 3. It couldn't be made a decision that school meal service was direct cause to increase the occurrence of dental caries on the permanent teeth in Korean primary school children.
