title: [Observation of the influence of chemomechanical caries removal on dentin adhesion by scanning electron microscope].
abstract: OBJECTIVE
  To observe the influence of chemomechanical caries removal on dentin adhesion by scanning electron microscope.
  
  
  METHODS
  The ultrastructure of dentin surfaces and adhesives-dentin bonding interfaces after caries removal by chemomechanical method or drilling were observed.
  
  
  RESULTS
  Less smear layer in dentin surface, resin tags in the interface between dentin and Prime&Bond NT/compomer and numerous resin tags and more uniform and closer hybrid layer in the interface between dentin and Adper Prompt-L-Pop/composite were found in chemomechanical preparation than in drilling preparation.
  
  
  CONCLUSIONS
  Chemomechanical caries removal can benefit dentin adhesion.
