dc.description.abstractObjective To determine the effect of home and over the counter bleaching on the stainability of CAD/CAM restorative materials, and to correlate the surface roughness with discoloration. Material and Methods Specimens were fabricated from feldspathic ceramic, an hybrid ceramic, a resin nano-ceramic, and lithium disilicate-reinforced glass ceramic. After baseline surface roughness (Ra1) and color measurement, each material was randomly divided into three groups according to bleaching regimen as Opalescence PF and; Opalescence Go; control. Then, the second color and surface roughness (Ra2) measurements were made. Thereafter, all specimens were immersed in a coffee solution for 12 days and the third color measurement was made. Color and whiteness change (CIELAB- Delta E-ab, CIEDE2000-Delta E-00, whiteness index-Delta WID) were calculated after bleaching (Delta E1;Delta E(00)1;Delta WI(D)1) and immersion in the coffee solution (Delta E2;Delta E(00)2;Delta WI(D)2). Results According to both CIELAB, CIEDE 2000 and WI(D)formulas, the highest mean Delta E1, Delta E2, Delta WI(D)1, Delta WI(D)2 values were observed for LAVA Ultimate groups while the lowest values were measured for e.max CAD groups. The findings also showed that there was a positively significant relationship between Ra2, and Delta E2 and Delta WI(D)2. Conclusions Type of restorative materials and bleaching agents had an impact on color change after bleaching and immersion in coffee. Clinical Significance Home and over-the-counter bleaching agents may cause an increase in susceptibility of restorative materials to staining.
