title: Shear bond strength of a composite resin after delayed bonding to a polymerised dentine bonding system.
abstract: Polymerised adhesive may serve as a temporary sealant on prepared dentine surfaces and may be used as a precursor to the final bonding of a resin restoration. This procedure may, however, have an adverse effect on the strength of the final bond. This study was undertaken on 40 extracted human molar teeth to assess the effect of delayed bonding on the shear bond strength of a composite resin luted with a luting resin to abraded dentine treated with the Scotchbond Multi-Purpose (SMP) Bonding System (3M). No significant difference (p = 0.969) could be demonstrated between shear bond strengths achieved after immediate and delayed bonding to the polymerised Scotchbond Multi-Purpose adhesive.
