Abstract:

Postpartum hemorrhage is a common complication after tooth extraction. Many systemic and local factors can cause bleeding after tooth extraction. Reasonable selection and application of local hemostatic material for filling extraction socket is a good way to reduce and prevent post-extraction bleeding，and reduce the suffering of patients. With the development of oral materials science，more and more hemostatic materials are used to treat and prevent bleeding after tooth extraction. All kinds of hemostatic materials for filling extraction socket have a certain hemostatic effect. In clinical operation，our treatment should be based on the situation of tooth socket bleeding and the patient's general and economic conditions. In order to help clinicians to choose and apply hemostatic material，we will introduce the commonly used hemostatic materials，and analyze the characteristics of commonly used tooth extraction hemostatic materials in this paper.

Key words: tooth socket, bleeding, tooth extraction, hemostatic material

摘要：

拔牙后出血是牙拔除术后常见的并发症，全身及局部多种因素可导致拔牙后出血。合理的选择及应用局部止血材料覆盖和（或）充填拔牙窝是治疗及预防拔牙后出血的重要措施。随着口腔材料学的发展，越来越多的止血材料被用于处理及预防拔牙后出血。各类止血材料覆盖及充填拔牙窝后均有一定的止血效果，在临床操作中，应根据拔牙窝出血情况、患者全身及经济状况进行合理选择。文章将对目前临床上常用的拔牙窝止血类材料进行介绍，并结合患者全身及局部创伤情况，分析常用拔牙窝止血材料的特点，为临床医生合理选择及应用拔牙窝止血材料提供帮助。
