胶原蛋白塞及胶质银止血明胶海绵在预防下颌阻生牙拔除后并发症中的效果分析

Analysis of the effect of collagen plug and haemostatic gelatin sponge with colloid silver in preventing complications after extraction of mandibular impacted teeth

目的:比较胶原蛋白塞及胶质银止血明胶海绵在预防下颌阻生牙拔除后短期并发症中的临床效果。方法:选择双侧下颌第三磨牙阻生分类一致且均需要拔除的22例病人作为研究对象,采用分口设计,每位病人的左右下颌第三磨牙随机分为观察组和对照组。观察组拔牙创内填塞胶原蛋白塞,对照组拔牙创内填塞胶质银止血明胶海绵。比较2组术后30 min出血情况,术后第1、3天疼痛程度,术后第7天张口受限及干槽症发生情况。结果:观察组术后30 min出血率低于对照组,但差异无统计学意义(P>0.05)。观察组术后第1、3天疼痛VAS评分均低于对照组(P<0.05);2组术后第3天疼痛VAS评分均明显低于术后第1天(P<0.01)。观察组术后第7天张口受限发生率低于对照组,但差异无统计学意义(P>0.05)。2组均无干槽症发生。结论:胶原蛋白塞预防下颌阻生牙拔除后短期并发症的效果较好,值得推广。

Objective:To compare the clinical effects of collagen plug and haemostatic gelatin sponge with colloid silver in preventing complications after extraction of mandibular impacted teeth.Methods:Twenty-two patients with bilateral symmetrical impacted mandibular third molars requiring extraction were selected as the study subjects.A split-mouth study was performed,and each patient′s left and right mandibular third molars were randomly divided into an observation group and a control group.The observation group was filled with collagen plugs in the Socket,while the control group was filled with haemostatic gelatin sponge with colloid silver in the socket.The bleeding 30 min after operation,the degree of pain on the first and third days after operation,and the occurrence of mouth opening limitation and dry socket on the seventh day after operation between the two groups were compared.Results:The postoperative bleeding rate 30 min after operation in the observation group was lower than that in the control group,but the difference was not statistically significant(P>0.05).The VAS pain score in the observation group was lower than that in the control group on the first and third days after operation(P<0.05),and VAS pain score on the third day after operation in the two groups was significantly lower than that on the first day after operation(P<0.01).The incidence of postoperative mouth opening limitation on the seventh day after operation in the observation group was lower than that in the control group,but the difference was not statistically significant(P>0.05).No dry socket occurred in the two groups.Conclusions:The effect of collagen plug in preventing complications after extraction of mandibular impacted teeth is better than that of haemostatic gelatin sponge with colloid silver,and the former is worthy of popularization.
