Purpose: The purpose of this study was to compare the effectiveness of a laser fluorescence (LF) device (DIAGNOdent) with a visual and radiographic scoring system for in vitro detection of occlusal caries and to evaluate the effect of 1% NaOCl immersion on the LF readings.
Methods: A total of 54 extracted third molars with macroscopically intact occlusal surfaces were selected. Three examiners assessed 105 sites by visual inspection (VI), bitewing radiography (BWR), and LF.
