Hemostasis should be undertaken using collagen (Colla-Cote, Integra Life Sciences, Plainsboro,NJ), calcium sulfate (Capset, Lifecore Biomedical, Chaska, MN), or calcium hydroxide; however, astringents such as ferric sulfate should be avoided, as the coagulum they leave behind may promote bacterial growth and may compromise the seal of the repair. (書:Pathway to the pulp)(C) 的凝結物會造成細菌滋生,且密封性降低.
