The aim of this study was to evaluate the variation in microleakage
of Class V composite restorations pre-treated with three different dentin bonding agents. The 24 cavities were randomly divided into four groups. The cavity walls of the first group were covered by Gluma ® 2000, the walls of the second group were covered by Syntac and the third group by Compoglass adhesive. The fourth group was a control group. The marginal microleakage was examined by extension o f dye ink penetration under a light microscope. After partial demineralisation of the samples, the composite fillings were extracted from the cavities. The lowest dye penetration was found in cavities covered by Syntac (0.27 mm, SD 0.18) followed by Compoglass 0.77 mm, (SD 0.30). Gluma® 2000 showed dye penetration of 0.85 mm (SD 0.25), and f i nally the control group showed dye penetration o f 0.88 mm (SD 0.38).
