Some epidemiologic evidence on the etiology of caries

Abstract

While laboratory research has identified multiple causal factors in dental caries, few epidemiologic studies have been conducted on large representative populations that have utilized enough variables to test the current models of causation. Data from a large, representative study were available to the authors for secondary analysis. The epidemiology of dental caries as presented in the study indicates that the caries patterns in a free-living population were consistent with an infectious and nutrition model of causality. The genetic explanation, while represented in the data, was not as consistent with the findings as the infectious and nutritional explanations.
