Abstract

The authors selected socio-geographically different sample areas. The dental caries on the deciduous teeth was observed and evaluated in each sample area. And then, dft rate, dft index, dt rate and ft rate were calculated and compared. The obtained results were as follows; 1. The dft rate of the deciduous teeth was 33.28% in the metropolitan area, 19.78% in city area, 18.21% in town area, 13.48% in field area, 15.26% in coastal area, 22.11% in mountain area, and 20.37% in hot spring area. 2. The dft index of the deciduous teeth was 4.51 in metropolitan area, 2.78 in city area, 2.59 in town area, 1.95 in field area, 2.30 in coastal area, 3.03 in mountain area, and 2.85 in hot spring area. 3. The dt rate of the deciduous teeth was 66.51% in metropolitan area, 95.38% in field area, 98.94% in hot spring area, and 100% in the other areas. 4. The ft rate of the deciduous teeth was 33.48% in metropolitan area, 4.61% in field area, 10.50% in hot spring area, and 0.00% in the other areas. 6. We could not find that the some dental cares for the dental caries on the deciduous teeth of Korean children were supplied in metropolitan area, and the track of dental cares was appreciated in the field area, but no trace was indentified in the coastal, mountain, city, and town areas.
