Abstract

The purpose of this study was to compare the efficacy of ferric oxalate, aluminum oxalate, or Tenure dentin conditioner, a marketed product containing aluminum oxalate, at reducing the permeability of human dentin in vitro. Topical treatment with these acidified agents or 2.5% nitric acid for 10, 30, or 60 seconds was compared. The results indicate that 10-second treatments of dentin with all agents increased dentin permeability. Extending the treatment to 30 seconds produced a decrease in dentin permeability for acidified aluminum and ferric oxalate with 60-second treatments being even more effective. Treatment with Tenure dentin conditioner for 60 seconds did not reduce dentin permeability as well as treatment with the other oxalate salts.
