Abstract

Introduction: Diagnosing the necessity of cavity preparation and restoration in demineralized proximal areas is always considered as a challenge in restorative treatment planning. The purpose of this study was to assess the performance of the laser fluorescence (LF) technique in detection of proximal cavities. Materials & Methods: In this clinical trial, 44 proximal surfaces in 38 dental students were evaluated. The selected patients had radiolucent proximal lesions restricted to inner half of enamel or outer third of dentine in bitewing radiographs (BW). DIAGNOdent pen (LF pen) device was used to determine the presence or absence of caries cavities in suspected proximal surfaces. Orthodontic elastic separators were then placed in the contact areas to provide enough space for direct visual and tactile examination. The sensitivity, specificity and accuracy of the laser fluorescence technique were calculated versus the reference standard. The ROC curve was drawn and the best cut-off to determine the presence or absence of proximal cavities was determined. Results: Using DIAGNOdent pen, the optimal cut-off for detecting proximal cavities was 18. The sensitivity, specificity and accuracy of DIAGNOdent pen for diagnosing proximal caries cavities were 100 per cent, 97.3 per cent and 97.7 per cent, respectively. Conclusion: Due to the high diagnostic accuracy of DIAGNOdent pen in detecting proximal caries cavities, it can be used as a valuable supplement in restorative treatment planning.
