【摘要】 目的:探讨在下颌阻生牙拔除术后应用胶原蛋白海绵的临床效果。方法 :选取2016年11月—2017年11月在天津市口腔医院行下颌阻生牙拔除术的患者150例,随机分为常规组和胶原蛋白海绵组。胶原蛋白海绵组患者进行下颌阻生牙拔除术后在拔牙窝内填入胶原蛋白海绵,常规组患者则只进行常规拔牙处置,比较2组患者拔牙后的相关情况。采用SPSS 20.0软件包对数据进行统计学处理。结果:胶原蛋白海绵组患者拔牙后30 min内拔牙窝出血率显著低于常规组(P<0.05),拔牙后第1天和第3天疼痛程度评分显著低于常规组(P<0.05),拔牙后干槽症和其他并发症的发生率显著低于常规组(P<0.05)。结论:在下颌阻生牙拔除术后应用胶原蛋白海绵,不仅可以有效减少术后出血量,而且可以有效降低术后干槽症和其他并发症的发生率,值得推广应用。更多还原

【Abstract】 PURPOSE: To analyze the effect of collagen sponge after mandibular impacted teeth extraction. METHODS:One hundred and fifty patients with mandibular impacted teeth extraction in our hospital during November 2016 and November 2017 were randomly divided into routine group and collagen sponge group. Patients in the collagen sponge group were treated with collagen sponge after extraction of mandibular impacted teeth, while patients in the routine group were treated routinely.The clinical effects of the two groups were compared. The data were analyzed by using SPSS 20.0 software package. RESULTS: The bleeding rate within 30 min after extraction in the collagen sponge group was significantly lower than that in the routine group(P<0.05). The pain score of the collagen sponge group was significantly lower than that of the routine group at first and third day after extraction(P<0.05). The incidence of dry socket and other complications in collagen sponge group was significantly lower than that in the routine group after treatment(P <0.05).CONCLUSIONS: The use of collagen sponge after extraction of mandibular impacted teeth can not only reduce the amount of postoperative bleeding, but also effectively reduce the incidence of postoperative dry socket and other complications.更多还原
