Abstract

Statement of the Problem: Composite bond to dentin is crucial in many clinical conditions particularly in deep cavities without enamel margins due to insufficient penetration of adhesive into demineralized dentin.Purpose: The aim of this study was to assess the shear BOND STRENGTH (SBS) of a methacrylate- based and a silorane-based composite resin to surface and DEEP DENTIN after pretreatment with DIMETHYL SULFOXIDE (DMSO).Materials and Method: Eighty extracted human premolars were randomly divided into two groups of flat occlusal dentin with different cuts as A: surface group (sections just below the dentinoenamel junction (DEJ) and B: deep group (2 mm below DEJ).Each group was randomly assigned to 4 subgroups and their samples were restored with Adper Single bond (ASB) and Filtek Z350 or Silorane system Adhesive (SA) and Filtek P90 composite resins, using a 3×3mm cylindrical plastic mold. following these steps, the subgroups were assigned as SubgroupA1: SURFACE DENTIN+Silorane System Primer (SSP)+Silorane System Bonding (SSB)+P90; Subgroup A2: SURFACE DENTIN+37% etchant (E37%) +Adper Single Bond (ASB)+Z350; Subgroup A3: SURFACE DENTIN+ DMSO+SSP+SSB+P90; Subgroup A4: SURFACE DENTIN+E37%+DMSO+ASB+ Z350; Subgroup B1: DEEP DENTIN+SSP+SSB+P90; Subgroup B2: DEEP DENTIN+ E37%+ASB+Z350; Subgroup B3: DEEP DENTIN+DMSO+SSP+SSB+P90; Subgroup B4: dentin+E37%+DMSO+ASB+Z350. The specimens were thermocycled at 5±2.55±2oC for 1000 cycles and then tested for SBS.Results: Using DMSO as dentin conditioner increased SBS of ASB to DEEP DENTIN (p< 0.001) and SBS of SA to SURFACE DENTIN (p=0.003) but had no effect on SBS of SA to DEEP DENTIN (p=1.00).Conclusion: The ability of DMSO to increase SBS of ASB to DEEP DENTIN provides a basis for improving bonding of this composite resin in deep cavities.
