title: Comparative bond strengths of autopolymerising denture resin and light cured composite resin to denture teeth.
abstract: OBJECTIVE
  To investigate the shear bond strengths between light cured composite and autopolymerised acrylic resin bonded to acrylic resin denture teeth.
  
  
  METHODS
  Surface treatments were used for the denture teeth included wetting with methylmethacrylate (MMA) monomer, composite bonding agent and acid etching. The samples were divided into seven groups. Two groups of specimens were immersed in distilled water for 30 days to hydrate the teeth. Five other groups of embedded denture teeth were stored in air at room temperature for 30 days.
  
  
  RESULTS
  Analysis of variance indicated statistically significant differences between groups (P < 0.001).
  
  
  CONCLUSIONS
  The greatest bond strengths to denture teeth were in acrylic resins polymerised with pressure and wetted with monomer. The bond strengths of hydrated and unhydrated samples gave similar results both with acrylic resins and composites.
