Effect of Home Bleaching on the Optical Properties and Surface Roughness of Novel Aesthetic Dental Ceramics

The optical qualities of cutting-edge aesthetic dental ceramics are crucial for great aesthetics and may be impacted by various bleaching methods. objectives this study were to evaluate how home affected the translucency parameter (TP), contrast ratio (CR), total color difference (?E), surface roughness (Ra) ceramics, including innovative ultra-translucent zirconia. three varieties that tested—IPS e.max-Press (IPS); classic zirconia with feldspathic layering (LZr); translucent (TZr)—were each represented seven samples. samples bleached at using 15% carbamide peroxide six hours a day days. Each specimen’s pre- post-bleaching CIE L*a*b* values measured spectrophotometer, TP, CR, ?E determined. Ra via 3D profilometry. In comparison pre-stage results, statistical analysis showed significant decrease in TP increase CR LZr TZr post-stage (p < 0.05), but not IPS = 0.398). results also substantial variations 0.020). readings during noticeably greater than those 0.018). Home had an impact on characteristics texture ceramics. Additionally, stability TZr.
