一般注記We analyzed the relation between the number of missing teeth (MT) and the rate of market share of fluoride containing dentifrice (RMSF) by birth year cohort. The data analysis used the results of 10 Japanese National Surveys of Oral Health from 1952 to 2011. The data of MT for those born from 1926 to 1973 were divided into 8 groups every six years. The changes in MT and RMSF over time were analyzed for each group of birth year cohorts. In the older subjects, MT increased with age, and RMSF was low. In subsequent generations of subjects, MT was low and RMSF high. We found that the decrease in MT correlated with the increase in RMSF, suggesting that the 8020 goal (Japanese 80 years old should have 20 teeth) will be accomplished after 15 years.
