• A statistical investigation on dental caries in the so-called 6-year-old molars in 36, 909 (_??_ 19, 011, _??_ 17, 898) pupils in 45 primary schools in Kumamoto City, Kumamoto Prefecture, was made by the Research Group in the Association, using “Records of Oral Examinations in the Primary Schools, 1965”. All the 6-year-old molars in these children which had been affected by caries at all were counted regardless of their being treated or not, and a child having either one or four (upper, lower, left, and right) carious molars was counted as one head. The result was a follows:<BR>1. The caries incidence rate of the permanent first molar in the pupils of all the primary schools in Kumamoto City was 52.11% (_??_ 48.23%, _??_ 56.22%), and in area levels, the highest rate was that of the mountainous area, followed by those of the residencial, farming, and business areas, between the latter two, however, hardly any difference was observed. The actual incidence rate for each school varied so much that no classification was possible.<BR>2. The ratios of the carious 6-year-old molars in all the primary school pupils in Kumamoto City were: 1st graders 19.17%, 2nd graders 20.88%, 3rd graders 17.67%, 4th graders 12.42%, 5th graders 9.65%, and 6th graders 8.72%. That is, the majority, 62.2%, of these molars were attacked by caries during the 1-3 Grades. This tendency was remarkable in schools having high ratios.<BR>3. The caries incidence rates of these pupils in past years were also studied, resulting in the findings that every year the ratio of the 1st graders was higher than that of the previous year. While it was 12.17% in 1960, it was 20.64% in 1965, indicating increase of approximately 1.7 times during the past six years. The difference in the ratio resulted from this yearly increase continued unchanged as the newly entered pupils grew up to be 6th graders, showing clearly parallel lines.<BR>4. The percentage of the permanent teeth affected by caries per head of the pupils in Kumamoto City was 35.67%, while that of per tooth was 54.93%. Although this condition is rather good compared to those in other districts, it is still very far from the perfect treatment on childrens teeth.
