Effect of Cut-Off Points on Performance of Laser Fluorescence for Detecting Occlusal Caries

This in vitro study aimed to evaluate the influence of cut-off points on the performance of laser fluorescence(LF) in detecting occlusal caries in permanent and primary teeth. The use of different cut-off points influenced the performance of LF device in detection of occlusal caries in both kind of teeth, but the performance in permanent teeth suffered more influence from variation of cut-off points scales than in primary group.
