title: [A scanning electron microscope study on resin bonding amalgam restoration in cavity].
abstract: OBJECTIVE
  To detect the bonding interface of resin bonding amalgam restoration(BAR) with scanning electron microscope(SEM).
  
  
  METHODS
  Sixty-five healthy teeth were divided into 4 groups, including one control group(5 teeth) with regular amalgam restoration and 3 experimental groups (20 teeth each) with 3 kinds of resin bond agent. The section was detected with SEM to evaluate the resin-bonding-amalgam interface.
  
  
  RESULTS
  The resin bonding agent could fulfill the micro-leakage between amalgam and enamel or dentin, and seal the dentin tubules completely. The resin bonding agent could bond enamel, dentin and amalgam well. The chemical curing agent had a better effect than the light curing agent.
  
  
  CONCLUSIONS
  BAR reduces the micro-leakage around amalgam restoration and provides a better way to prevent secondary caries. Supported by Research Fund for Young Researches from Bureau of Health of Shanghai Municipality (Grant No.2007Y03).
