In the first grade, the results of oral examination of study group had been more poor than control group.
Six years later after implementation of the program, DMF rate, DMFT rate, DMFS rate and DT rate of study group were all lower than control group. Among the results DMFT rate and DMFS rate were significantly lower than control group(p<0.01). FT rate was not significantly higher than control group.
The DMFT index and DMFS index per child were significantly lower than control group(p<0.05). Debris index was slightly fair than control group.
Daily tooth-brushing frequency was about 2 times at both group.
There were also no significant difference between the two groups about intake frequency of caries-inducing foods and pure food intake. 87.0% of the school children, 72.7% teacher, 96.7% parents were responded this program to be beneficial for dental health.
