Numerous risk indicators, that is, characteristics or measurements that assist in the prediction of caries, whether or not they are involved in caries causation, have been suggested for children. Unfortunately, more of the supportive data come from cross-sectional correlations with accumulated caries experience than from prospective, protocol-based incidence studies. The prospective studies employed different combinations of potential predictors in a variety of populations, varied considerably in sample size and quality, and have not produced a broadly applicable index or set of criteria for risk assessment. More and higher-quality comprehensive, longitudinal, multifactor studies of implicated risk indicators are needed to obtain firm support for their associations with caries incidence, to clarify the strengths of these associations in differing populations, and to reveal the extent to which the risk indicators provide independent as opposed to redundant information. In addition, although the nature of the disease process suggests that many of the proposed indicators may well be appropriate throughout life, validation studies in adult populations are largely absent or incomplete.
