The Japan Health Care Dental Association has made strong efforts to prevent caries developments of the children s permanent teeth since their establishment. It appears that a risk assessment and a regular oral health management are indispensable for preventing caries developments. But, there has been no survey that compared the clinical index of regular checkup receivers to occasional checkup receivers. When the schoolchildren from the low grades of the primary school to the junior high school were divided into the two age groups, the first half group with the age of 6-10 and the second half group with the age of 11-15 and even the same regular oral health management was applied on the both groups, it appeared that there were more caries developments in the latter half group than in the first half group. Then, the DMF increase cases were surveyed on the first and second groups and regular checkup receivers and occasional checkup receivers in the observation period with the cooperation of the members of the Japan Health Care Dental Association. The survey revealed that DMF increase cases were significantly less in the first half group than in the latter half group. Its difference was especially remarkable in the serious cases with more than 2 and 3 of DMF increase. It also revealed that the latter half group showed more caries development than the first half group, which was true on the both regular checkup receivers and occasional checkup receivers. In the future, the aim for effective caries preventions will be required by pursuing the causes of the difference in the caries development between two age groups and also between regular checkup receivers and occasional checkup receivers.
