Caries detection accuracy by multiple clinicians and techniques.

This study compared caries detection by multiple clinicians with the accuracy of detection with Caries Detector dye. Four clinicians rated the extent of caries on 100 extracted teeth. After dye application, visual assessment of residual dye was recorded for each specimen. This was repeated after the teeth were embedded in epoxy resin and sectioned. The results indicate that although reasonably accurate overall, clinicians often disagree whether caries is present. The use of a caries detector solution may be a valuable adjunct tool to correct caries diagnosis.
