Abstract This study compared the performance of three laser fluorescence (LF) devices (DIAGNOdent Classic, DIAGNOdent Pen and KEY3 laser) under standardized laboratory conditions for detecting subgingival deposits of calculus on root surfaces of extracted teeth in typodonts. While some studies show the efficacy of LF devices for calculus detection compared with conventional periodontal probes, little is known regarding the differential performance of different LF devices. In this laboratory study, extracted teeth were set in an anatomical configuration in stone typodont models in a phantom head and impression material used to replicate periodontal soft tissues. A total of 240 sites were assessed on three occasions using the three different LF devices and results compared to direct microscopic examination of the roots of the extracted teeth under magnification. The KEY3 showed greater accuracy (86.4 %) than the DIAGNOdent Pen (84 %) and DIAGNOdent Classic (80.2 %). The intra-examiner reproducibility was also higher for the KEY3 (mean Cohen kappa 0.74) than the DIAGNOdent Pen (0.66) and DIAGNOdent Classic (0.6). Of the three LF devices, the KEY3 has greater accuracy and reproducibility.
