Before undertaking the community oral health project, it is essential to collect information about the present situation of the community and to diagnose the community we live.
Especially as the prevalence rate of dental caries decreases, the mean values in the community may not help us to have a true picture of the community, but also lead to misunderstand an actual condition of the community. Health care administration in Japan is by the age of children in the control of Ministry of Education, Culture, Sports, Science and Technology or Ministry of Health, Labor and Welfare, and in the control of municipal borough or prefecture, resulting in no consistent data available. Therefore, as a board member of Yachiyo Dental Association in charge of sanitary affairs. I have arranged a database of the oral health in our community and used it for “Healthy-town Building Program of Yachiyo City ” Information collected in the survey reveals an expanding gap between the regions, for example, over half of 12 year age group have DMFT 1 and less, but a quarter of children have DMFT 4 and more, and the region with high DMFT value and high percentage of untreated caries at the 12 year age group has tendency to have low rate of having a dental check at the age of 3.
