Abstract
Objective To evaluate the effect of glaze on relative translucency of B,C color IPS e.max LT core material.Methods Disc-shaped base material IPS e.max LT samples which were 0.3mm and 0.5 mm thick were prepared and divided into eight groups by color number B1,B2,B3,B4,C1,C2,C3,C4,n =5.0.3 mm-thick dentin porcelain of the same color as the base material was decorated over the surface.Finally,all the samples were glazed and sintered.Relative translucency was determined using a spectral colorimeter and statistically analyzed.Results Analysis results of samples of color B and C showed that thickness was a significant factor for their relative translucency (P ＜ 0.05).Using the same color,relative translucency of 0.8 mm groups was higher than that of 0.6 mm group (P ＜ 0.05).For samples of 0.6 mm,glazing with color B significantly decreased relative translucency (P ＜0.05),but had no significant effect on samples of 0.8 mm (P ＞ 0.05) except group B4.For color C,glazing had a significant effect on relative translucence of groups of 0.6 mm excepted C3 groups (P ＜ 0.05).For groups of 0.8 mm,glazing showed significant effect on C1 and C4 (P ＜ 0.05),but not on C2 and C3 (P ＞ 0.05).Conclusions The thickness ratio of core materials to dentine porcelain contributes to match color and relative translucency between all-ceramic restoration and natural teeth.Glaze can improve the transparency of all-ceramic restorations their aesthetic effect.关键词
