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.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
