An epidemiological study of periodontal disease, using four methods of assessment of severity of periodontal disease, was conducted on a representative sample of 1,976 New Mexicans aged 18 to 44 years. Periodontal disease was assessed using PI and PDI and radiographic and mobility assessments. One objective of the study was to assess whether radiographic scores and measurements of clinical mobility added significantly to the precision of discrimination between the severity of periodontal disease in populations when using the PI and PDI. Findings indicated that the PI discriminated between population groups as efficiently as the PDI plus radiographic and mobility scores. In this study females had less severe periodontal disease than males; Anglos had less severe disease than Spanish‐Americans, Mexicans, American‐Indians, and Negroes; persons with a greater number of years of schooling and persons in the higher socioeconimic groups had less severe periodontal disease than persons with fewer years of schooling and in the lower socio‐economic groups respectively; urban and rural persons had a similar severity.
