Descrição: dc.descriptionObjectives: To evaluate different intervals of exposure to staining solutions and artificial aging on translucency parameter (TP00) of CAD-CAM materials. Material and Methods: One millimeter thick square-shaped specimens (N = 288) were cut from Cerasmart (CS), IPS e.max OE), Lava Ultimate (LU), Shofu HC (SH), Vita Enamic (VE), and Vita Suprinity (VS) and were divided into laboratory and chairside polishing. Reflection wavelength spectra, CIE D65 standard illuminant, 2 degrees standard observer, SO, UV included, SAV aperture, 6 mm diameter, were recorded at 10 nm sensitivity against white and black calibration tiles using a benchtop spectrophotometer. Subsequently, they were converted into CIEDE 2000 TP00. After baseline measurements (T0), the specimens were divided as follows (n = 8): staining in coffee (C) and wine (W), for 60 (T1) and 120 hours (T2), and accelerated artificial aging (A). Artificial aging (tSO 4892-2 standard) was performed in two cycles of 150 Wm(2), for T1 and T2, respectively. TP measurements were repeated at T1 and T2. Data of TP00 retention were submitted to analysis of variance and Fisher's PLSD multiple comparison test (alpha=0.05). Results: Fisher's PLSD critical differences among materials, time intervals and staining/aging were 0.16, 0.11 and 0.11, respectively. SH showed the highest TP00 followed by LU > CS > IE = VS > VE. For all time intervals, the lowest retention was observed with C. W, and A presented similar values. Conclusions: Translucency Parameter was material, time and staining/aging-dependent material. In majority of cases, it decreased upon staining/aging.-
