 note = {application/pdf, The important role of the deciduous tooth in growth and development during the infant period shows a strong tendency to suffer from decay before the completion of a deciduous dentition. The prevention of an increasing tendency toward dental caries in young children is thus an urgent task in pediatric dental medicine, and caries prevention must be performed under public hygienic policy affecting all the public. Thus, accurate epidemiologic grasping of the actual phase of deciduous tooth decay is very important for preparing preventive measures against dental caries in infants. The speaker et al. carried out a dental inspection of kindergarten children in Shihchiachuang-city , China and investigated conditions of those suffering from dental caries and its oral conditions. Their results were subsequenty compared with those of the Welfare Ministry who had investigated children of the same age in Japan and then discussed. The survey was performed in regard to malocclusion, tooth Anomaly, gingivitis, inspection of dental caries and included an examination of caries activity in 600 kindergarten children of Shihchiachuang-city (334ma1e, 266 female). The dental caries inspection was carried out according to the criteria of the Japanese Welfare Ministry and the results were classified according to the four grades of caries progression from C_1 to C_4. We carried out a dental inspection of three-to six-year-old kindergatren children in Shihchiachuang-city, compared its results with those of a Japanese survey and obtained the following conclusions: 1) The frequency of malocclusion was 13.8%; this showed no difference between China and Japan, and also no difference in tooth disorder. 2) The rate of the gingivitis contraction was 10.8% -very low in comparison with 40 to 70% rate in Japan. 3) Regarding the comparison of the caries incidence rate mean number of dmf and the rate of dmft, the rate of those suffering from caries, especially in three-year-old children of Shihchiachuang-city was higher, showing a tendency toward the earlier appearance of dental caries in comparison with Japanese infants.},
