Clinical Validity of Fluorescence-Based Devices vs. Visual-Tactile Method in Detecting Secondary Caries

Posted: January 6, 2025
A recent study compared the clinical validity of fluorescence-based devices and the visual-tactile method in detecting secondary caries around resin composite restorations. The study included 20 participants with 30 restored teeth and evaluated the accuracy of three diagnostic methods: visual-tactile method, light-induced fluorescence camera (VistaCam iX), and laser-induced fluorescence device (DIAGNOdent pen). Results showed that DIAGNOdent pen had the highest sensitivity for detecting enamel and dentin caries, followed by VistaCam and the visual-tactile method. However, the visual-tactile method demonstrated higher specificity values. Both fluorescence-based devices and the visual-tactile method are reliable for detecting secondary caries, with DIAGNOdent pen being accurate for both enamel and dentin. VistaCam is effective for enamel caries only. Inter-examiner reliability was high for all assessment methods, emphasizing the importance of training and calibration for accurate results. The study suggests that a combination of different diagnostic methods could provide the best approach for detecting secondary carious lesions around resin composite restorations.
