The pH of nine commonly used hemostatic agents was measured. Three measurements were recorded for each solution, and values ranged from 0.7 to 2.0. The effect of exposure to one hemostatic material, ferric sulfate solution (Fe2(SO4)3), on the dentinal smear layer was investigated. Prepared extracted teeth were exposed for periods ranging from 30 seconds to 5 minutes to an acidic ferric sulfate-based hemostatic agent. A smear layer was clearly demonstrated on a control specimen; however, the dentinal smear layer was rapidly removed by exposure to the hemostatic agent, and peritubular dentin was lost after prolonged exposure.
测量了九种常用止血剂的pH值。每种溶液记录三次测量值，范围为0.7至2.0。研究了暴露于一种止血材料硫酸铁溶液（Fe2(SO4)3）对牙本质玷污层的影响。将制备好的离体牙暴露于基于酸性硫酸铁的止血剂中30秒至5分钟。对照标本上清晰可见玷污层；然而，暴露于止血剂后牙本质玷污层迅速被去除，长时间暴露后管周牙本质丢失。
