Diagnosis and prediction of root caries.
Diagnosis is the process of recognizing diseases by their characteristic clinical signs and symptoms. Diagnostic ability varies considerably between and among examiners, and, consequently, the accuracy of the diagnosis can be questioned. Root caries is a disease for which there are several clinical signs (location, color, surface texture, and surface cavitation). Unfortunately, these signs are open to broad clinical interpretation. As a result, estimates of disease occurrence (incidence rate) have ranged from 0.87 to 8.20/100 surfaces at risk/year or 0.15 to 0.43 lesions/person/year for adults living independently in the community. When multiple examiners are utilized, interexaminer agreement has been reported to be relatively good but could be further improved by minimizing the effects of several sources of examiner disagreement, including the absence of a global consensus on the signs which indicate the presence of root caries. The use of a diagnostic test can enhance the diagnosis and prediction of root caries, but the development of useful tests is hindered by the lack of an accurate clinical standard of diagnosis. At this time, diagnostic tests for root caries are quite limited and of questionable value. A powerful predictive tool for root caries would result from the combination of risk assessment measures and a valid diagnostic test developed with use of standardized and accurate methods of clinical diagnosis.
