dc.description.abstract"Introduction: In aesthetic rehabilitations, we must take into account the primary and secondary optical properties. Objectives: To evaluate the emission intensity of fluorescence between resin cement and glass-ceramic. Materials and Methods: two self-adhesive resin cements were used, as well as glass ceramic discs and composite resin. The ceramic cylinders were cut with a thickness of 1 and 0.5 millimeters and were bonded to composite resin discs with 0.5mm and polymerized for 40 seconds, for a total of n = 100. Fluorescence spectrums were obtained in a spectrofluorometer at a wavelength of 380 nanometers. Statistical analysis was performed using Student's t-test and one-way ANOVA, for a significance of p <0.05. Results: The samples of the control group were the ones who exhibited lower fluorescence with values of 1.99E13 a.u. in a thickness of 0.5mm and 2.95E13 a.u. in a thickness of 1 mm. In the samples of 1mm, all groups have similar values of fluorescence emission. In samples with 0.5mm, there are significant differences between each group (p <0.001) , in which the SCT group has higher fluorescence emission (1.06E14 a.u.). Conclusions: The thickness of the ceramic influences the final emission intensity of fluorescence. The emission intensity of fluorescence of the resin cements influences the final fluorescence of the glass ceramic. Clinical Implications: This study reveals the importance of the choice of the cement and ceramic thickness in a full ceramic rehabilitation."pt_PT
