Microleakage of five dentin bonding systems.
Class V preparations were placed in the buccal surfaces of 60 extracted human teeth such that approximately half of the preparations were above the CEJ and half below. The teeth were restored with Gluma/Pekalux, Tenure/Perfection, Scotchbond 2/Silux Plus, XR bond/Herculite XR, and Optec/Pentrafil 2 according to manufacturers' instructions. The sixth set of teeth was restored with a combination of XRbond/Silux Plus. The teeth were thermocycled and stained in silver nitrate. They were then scored for dye penetration. Scotchbond 2 showed the least dye penetration but not statistically less than the XR bond/Silus Plus combination. XR bond/Silux Plus showed significantly less dye penetration than XR bond/Herculite XR.
