Abstract
The purpose of this study was to evaluate the influence of different adhesive system’s composition on the sealing ability of a
dual cured resin cement when used for luting resin composite veneers. Thirty teeth were prepared for veneers with the
preservation of the enamel margins on previously extracted sound human anterior teeth. Polyglass veneers were prepared
following manufacturer’s instructions. Teeth were randomly assigned to three groups (n=10) and veneers were luted with a
dual-cured resin cement in conjunction with one of the following adhesive systems: 3 steps etch&rinse, 2 steps etch&rinse
and self-etch all-in-one. Teeth were thermocycled and immersed in 0.5% basic fuchsine solution for 24 hours. The
specimens were cut in a bucco-lingual plane in order to obtain a section at the middle of the mesio-distal dimension of the
veneer. Dye penetration along the tooth-cement (MTC) interface was evaluated at 40x and microleakage values recorded.
For each interface microleakage values were refered to the total length of that interface and data were subjected to
statistical analysis by Student’s t and Kolmogorov - Smirnov test at a p<0.05 level of significance. Significantly less
microleakage was associated with the use of etch & rinse adhesive systems comparing with the self-etch adhesive.
