Community dental health survey. Sydney Metropolitan Area—1972

Abstract

A bstract — Dental practitioners examined, in the home, after a previous interview by dental students, 1,354 subjocts randomly selected from the Sydney Metropolitan Area. The greatest increase in carious teeth was found from 15 at 20 years to 20 at 40 years of ago, about two teeth per person required fillings and the number of teeth missing increased more as a result of caries than periodontal disease in the older people. Fifteen per cent of subjects wore edentulous and only 15 per cent visited their dentist in the previous year on an average of 2.5 times.
