ABSTRACT
Objective:
To assess the effect of accelerated aging on the color and opacity of veneers bonded resin.Methods:
28 discs were made with IPS e.max Press A1 shade with the thickness of 0.4 mm.Ceramic discs were divided into 4 groups(n=7). BEAUTIFIL Flow A1 ,DEO-Link SE Transparent,Panavia F Light color and Viriolink N transparent resin cements were applied on the porcelain discs with a thickness of 0.1 mm.Curing was performed with a calibrated LED curing-light for 40 seconds.Color and opac-ity differences of the porcelain substructures after 65 h(150 kJ/m2 )of UV ageing test were examined with a colorimeter.The results were analysed statistically with One-way ANOVA,LSD(L)test.Results:
All samples showed significant changes in color and opaci-ty.The ΔE of all materials ranged from 0.6 to 2.29.DEO-Link SE showed the highest color change,while BEAUTIFIL Flow the lowest.The opacity changes ranged from 0.46 to 2.55 and its variation was not significant among groups except for Panavia F.Con-clusionThe accelerated ageing may lead to color changes of ceramic veneer bonded by resins in a clinically acceptable range(ΔE<3).
