The purpose of the present study was to determine the distribution and the prevalence of periodontal disease in adolescents and adults using the WHO method TRS 621 and to propose a method of presenting the results by a simple index system. On the basis of a medium term longitudinal 5‐yr project 1048 subjects were examined in age group 1 (15–19 yr) and 425 subjects in age group 2 (35–44 yr). Each subject had a full mouth examination for the presence of supra‐or subgingival calculus, pocketing, bleeding and recession and the PI (R ussell ). These epidemiologic data were characterized by the ratio Gingivitis: Periodontitis: Missing teeth by using solely the recordings for bleeding, pockets and missing teeth. The mean GPM index in Group 1 was 15.4:0.6:0.8. The mean GPM index in Group 2 was 12.0:4.6:7.7. The Periodontal Index is more subjective than the TRS 621 method. Full mouth recording is required for the suggested GPM/T index analogous to the DMFT index. This new scoring ratio makes it possible to present data of the progression rate of periodontal disease by the increment of tooth related P/T and M/T. Both indices with the common M‐value (Missing) might be used for longitudinal programs of control and prevention of periodontal disease and dental caries.
