Dental Caries Dental caries is evidence of dental decay on any surface of a tooth. Dental caries were determined by an oral examination conducted by a trained dentist as part of the National Health and Nutrition Examination Survey (NHANES). Study participants 2 years of age and over were eligible for the examination, as long as they did not meet other exclusion criteria. Both permanent and primary (or baby) teeth were evaluated.
