Dental diseases dealt with in this study are cavities (fillings, extractions and crowns), pyorrhea and baby teeth.The total number of teeth with dental diseases in Japan changes year by year depending on oral conditions ans are affected by the number of dentists, economic conditions and technical progress.This model contains 4 sectors: demography, cavities, pyorrhea, and baby teeth. The demographic sector covers populations of 5 three-year age groups under 14 years of age and 13 five-year age groups above 15 years of age. The cavities sector and pyorrhea sector are composed of populations of five-year age groups, on the other hand, the baby teeth sector uses populations of three-year age groups.From the total number of defective teeth, dental busyness and total dental care costs in Japan are calculated yearly from 1963 to 2010. The simulation results are used to modify the dental policies of Japanese administrators.This study is a research project of the Japan Dental Association.
