Abstract A CPITN survey was conducted involving 12832 Japanese subjects from 7 to 64 years of age. Subjects under 18 were schoolchildren, and 18‐year‐old and older subjects represented various social backgrounds, having been randomly selected from both urban and rural Japan. Fifty percent of the 7‐yr‐old children had signs of periodontal disease, and this percentage increased with increasing age. In those under 14, this increase in periodontal disease was mainly due to an increase in the proportion of children developing dental calculus. Subjects with 6 mm or deeper pockets were observed starting from the 20‐29‐yr‐old age group. In subjects over this age, the prevalence of periodontal disease was higher in men than in women. The percentages of subjects having pathologic pockets had increased remarkably in the 30‐44‐yr‐olds. In the 45–64‐yr‐old group, almost all subjects had some sign of periodontal disease, and the percentage of those with 4 or 5 mm pockets and 6 mm or deeper pockets were 37% and 21%, respectively
