title: Microleakage of mixed Class-V restorations placed with GIC-bases or dentin bonding agents.
abstract: The aim of this study was to compare the microleakage of a new generation of light-cured glass-ionomer cement bases and multistep dentin bonding agents with materials of the previous generation. Mixed class-V non-retentive cavities were prepared in freshly extracted third molars and filled with the test materials. After 250 thermocycles, the teeth were immersed in a dye solution for 48 h, sectioned longitudinally and evaluated under a stereomicroscope. The new bonding systems (i.e. Clearfil New Bond, Gluma Bond, Scotchbond 2 and Vitrabond) showed statistically significant lower microleakage values than the previous materials (i.e. Scotchbond DC, Ketac Bond, GC lining cement and 3M GIC). This in-vitro study emphasized the efficacy of the new generation of glass-ionomer cement bases and multi-step bonding agents.
