title: [Effect of dentin inorganic material during dentin bond].
abstract: OBJECTIVE
  In order to investigated the effect of dentin inorganic material during dentin bond.
  
  
  METHODS
  This study investigated the tensile bond strength (TBS) between 4-META/MMA-TBB resin and dentin treated with several dentin treating methods.
  
  
  RESULTS
  When the dentin was treated with acid-salt pretreating solution system (APSS) consisting of 10% citric acid and 3% ferric chloride to remove smear layer, and then re-treated with NaOCl to resolve dentin collagen and reveal dentin inorganic material, TBS of the dentin was 5.93 MPa, and higher than that of control group (3.71 Mpa) (P < 0.05) whose dentin was treated with distilled water only.
  
  
  CONCLUSIONS
  It was suggested that dentin inorganic material did play a proper role in dentin bond.
