© Medicina Oral S. L.Background: To compare the fluorescence-aided and conventionally excavated dentin with microhardness and shear bond strength(SBS) tests. Material and Methods: Twenty-four teeth with dentin caries were bisected through the center of the lesion into two halves. Forty-eight dentin specimens were embedded and mounted in an acrylic resin. All carious tissue was removed and classified as caries free using conventional visual tactile criteria. Then half of the specimens(n=24) were reinspected with fluorescence-aided caries excavation light(FACE) (FaceLight, W & H Dentalwerk, Bürmoos GmbH, Austria). Specimens were subjected to microhardness and shear bond strength testings. The fracture mode analysis was also performed. The data were compared with Student's t test and Chi-square test. Results: Residual caries was observed in 2 out of 24 conventionally excavated specimens with FACE inspection( p > 0.05). Mean Vickers hardness of the dentin was 61.5±5 in the FACE group and 70.3±3 kg/mm2 in the conventionally excavated group(p > 0.05). The mean SBS value of FACE group was 11.42±1.63 MPa and 18.27±1.43 MPa in conventionally excavated group. There was no statistically significant difference between conventional and FACE groups for microhardness and SBS tests(p > 0.05). There were also no significant differences on the fracture mode distributions of the groups(p > 0.05). Conclusions: FACE method could be considered as a promising technique for removing infected dentin.
