dc.description.abstractPURPOSE: While measurements of color and translucency have been well established in dentistry, fluorescence measurements have been mostly subjective. By utilizing a microplate reader to quantify fluorescence intensity of restorative materials and natural teeth, this study can provide a method for future research in fluorescence of dental materials. The purpose of this study was to establish a clinical guideline for material selection to achieve optimal esthetic results when utilizing Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) ceramic materials for a dental prosthesis. MATERIALS & METHODS: The intensity of fluorescence in extracted natural teeth, dentin, core materials, luting cements, and CAD/CAM ceramic materials, was initially measured. A second measurement of the fluorescence intensity was done with core materials and luting cements placed underneath the CAD/CAM ceramic materials as a layered compound. Finally, glaze was applied to the CAD/CAM ceramic materials and a third measurement of fluorescence intensity obtained. Materials used in the study: Core Buildup Luting Cement CAD/CAM Fluorescent Dyes Fluorescent Glazes LuxaCore Dual RELYX Ultimate Katana Zirconia Material HT/ML Lava™ Plus High Translucency Zirconia Effect Shade – Fluorescence IPS e.max Ceram Glaze Paste/Fluo FluoroCore 2 RELYX UNICEM IPS e.max CAD Colour Liquid Prettau Fluoreszenz Fluorescent Cad Spray Glaze ParaCore Multilink VITA ENAMIC CAD/CAM Material Build-It FR Panavia 21 ML Simple descriptive statistics, mean, and standard deviations were used to describe the fluorescence intensity of extracted natural teeth, dentin substructure, core build-up materials, luting cements, and different CAD/CAM ceramic restorative materials. One-way ANOVA (a = 0.05) was used to test if there was a statistically significant difference between the fluorescence intensity of natural teeth and CAD/CAM ceramic materials, also comparing glazed materials and layered compounds. RESULTS: There was a significant difference in the fluorescence intensity of extracted natural teeth when compared to dentin, core materials, luting cements, and CAD/CAM ceramic materials.
