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.
