Abstract

Aim: The aim of this study is to assess the accuracy of a laser fluorescence method "Kavo DIAGNOdent" in detecting occlusal enamel and dentinal caries in comparison with digital radiography using light microscope as gold standard.
Subjects and methods: 44 extracted teeth were scanned by Kavo DIAGNOdent. Then the teeth were arranged in blocks made from wax. Dental radiographs were obtained. This was done by digital radiography. The radiographs were examined by radiologists that were completely blinded . Then buccolingual sections approximately 300 µm thick were taken perpendicular to the occlusal surfaces using a water-cooled saw and examined under light microscope.

Results: For all measurements, Kavo DIAGNOdent had significantly higher percentage of correct enamel and dentinal caries diagnosis and had significantly higher sensitivity and specificity values than digital radiography (p<0.05).

Conclusion: According to the results of this study, Kavo DIAGNOdent is a more accurate tool than digital radiography in occlusal caries detection.
