title: Long-term bonding effectiveness of simplified etch-and-rinse adhesives to dentin after different surface pre-treatments.
abstract: OBJECTIVE
  To evaluate the effect of 2% chlorhexidine (CHX) and 30% proanthocyanidin (PA) application on the immediate and long-term bond strength of simplified etch-and-rinse adhesives to dentin.
  
  
  METHODS
  One hundred twenty extracted human molar teeth were ground to expose the flat dentin surface. The teeth were equally divided into six groups according to the adhesives used, either Tetric N Bond or Solobond M and pretreatments given either none, CHX, or PA. Composite cylinder was bonded to each specimen using the respective adhesive technique. Half the samples from each group (n = 10) were then tested immediately. The remaining samples were tested after 6 month storage in distilled water.
  
  
  RESULTS
  The mean bond strength of samples was not significantly different upon immediate testing being in the range of 8.4(±0.7) MPa. The bond strength fell dramatically in the control specimens after 6 month storage to around 4.7(±0.33) MPa, while the bond strength was maintained in the samples treated with both CHX and PA.
  
  
  CONCLUSIONS
  Thirty percent PA was comparable to 2% CHX with respect to preservation of the resin dentin bond over 6 months.
