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.
本研究的目的是比较草酸铁、草酸铝或一款含草酸铝的市售产品Tenure牙本质调节剂在体外降低人牙本质渗透性方面的效果。对用这些酸化剂或2.5%硝酸进行10、30或60秒的局部处理进行了比较。结果表明，用所有试剂对牙本质进行10秒处理会增加牙本质渗透性。将处理时间延长至30秒会使酸化铝和草酸铁处理后的牙本质渗透性降低，60秒处理则更有效。用Tenure牙本质调节剂处理60秒在降低牙本质渗透性方面不如用其他草酸盐处理有效。
