Guedes RS, et al. - This cohort study was conducted to assess the influence of initial noncavitated caries lesions on cavitated caries increment in preschool children. A significant predictor for cavitated caries increment after 2 years in preschool children at all ages was found to be the presence of moderate and extensive lesions at baseline. However, the presence of only initial caries lesions was also correlated, but with less severe caries incidence.
