目的:分析富血小板纤维蛋白(PRF)植入智齿牙槽窝对于预防干槽症的效果;方法:选取在东莞仁康医院进行阻生智齿拔除的220例患者,随机等分为对照组和观察组两组,对照组患者采用常规拔牙法,观察组患者组患牙拔出后组拔牙窝内放入PRF膜;结果:对照组患者组术后1个月内出血、渗血、疼痛、红肿等反应发生率明显高于观察组,差异具有统计学意义(P<0.05)。观察组患者组术后无干槽症发生,对照组患者攻击发生干槽症12例,两组术后干槽症发生率比较,差异具有统计学意义(P<0.05)。结论:PRF对于智齿拔出术后具有良好的消炎、止血、止痛等效果,并且可以促进创口的愈合,预防干槽症的发生。
Objective: To analyze the effect of platelet rich fibrin (PRF) implanted in wisdom tooth socket on the prevention of dry socket. Methods: 220 patients with impacted wisdom teeth removed at Renkang Hospital of Dongguan were randomly divided into control group and observation group The two groups and the control group were given routine tooth extraction. The PRF membrane was put into the socket of the experimental group after the tooth was pulled out. Results: The patients in the control group had hemorrhage, bleeding, pain, redness and other reactions within 1 month after operation The incidence was significantly higher than the observation group, the difference was statistically significant (P <0.05). In the observation group, there was no dry trough disease in the postoperative patients, and 12 cases of dry trough disease in the control group. The incidence of postoperative dry trough was statistically significant (P <0.05). Conclusion: PRF has good anti-inflammatory, hemostatic and analgesic effects after wisdom tooth extraction, and can promote wound healing and prevent the occurrence of dry socket.
