520	3		_aA primary reason for premature failure of Class II composite restorations is recurrent decay at the gingival margin. The integrity of the gingival margin depends on the bond formed with dentine. Using scanning electron microscopy (SEM)and histomorphologic technique, the purpose of this study was to characterise the adhesive/dentine (a/d)bond in dentine sections from the dentinoenamel junction (DEJ)and the cementoenamel junction (CEJ)with commercial adhesives of varying hydrophobic/hydrophilic composition. Materials and methods: The occlusal 1/3 of the crown was removed from 20 human third molars, this exposed the surface used for the DEJ sections. The teeth were sectioned occluso-gingivally into equal halves: one-half representing the DEJ; the remaining half was sectioned 4 mm deep to the exposed surface (CEJ). Each half was treated with the same adhesive. The teeth were randomly selected for treatment with Single Bond (SB, 3 M)or Dentastic UNO (UNO, Pulpdent)using wet bonding technique as per manufacturers' instructions. Thin (3-5 mm)sections of native a/d interfaces were cut and stained with Goldner's trichrome for light microscopic (LM)examination. Companion slabs were polished and acid-bleach treated, then analysed with SEM.
