title: Assessment of shear bond strength between three denture reline materials and a denture base acrylic resin.
abstract: OBJECTIVE
  This study reports the effect of five surface treatments on the bond strength established between three denture reline materials and a denture base resin.
  
  
  METHODS
  Cylindric columns of denture reline materials were bonded to columns of denture base resins that received one of the surface treatments: application of dichloromethane, the monomer of the denture base resin, the recommended bonding agent or the monomer of the denture reline material, polishing with 240-grit silicone carbide paper, and air abrasion. A control group without surface treatment was included for each material. Specimens were immersed in water for 1 day and then thermocycled. The strength at which the bond failed under shear was recorded.
  
  
  RESULTS
  None of the surface treatments significantly improved the bond strength of Kooliner. Triad bonding agent and denture base monomer applications most significantly improved the bond strengths of Triad and GC reline, respectively.
  
  
  CONCLUSIONS
  Triad bonding agent and denture base monomer should be used in conjunction with Triad and GC reline, respectively, when relining a denture base resin.
