半导体激光在老年根尖周炎患者根管治疗中的应用

目的探讨半导体激光在老年根尖周炎患者根管治疗中的作用。方法老年根尖周炎患者260例,随机分为观察组与对照组,观察组辅助应用半导体激光对常规方法根管预备后的根管进行消毒治疗,对照组未采用半导体激光辅助治疗。比较根管预备后24 h、72 h的疼痛程度和根管治疗疗效。结果根管治疗术后24 h、72 h观察组疼痛程度均轻于对照组(P<0.05)。观察组根管治疗6个月和1年成功率高于对照组(P<0.05)。结论老年根尖周炎患者在根管治疗过程中,应用半导体激光对根管进行消毒,可降低根管治疗术后疼痛程度,提高根管治疗成功率,具有一定临床应用价值。

Objective To investigate the role of semiconductor laser in the root canal treatment of elderly patients with periapical inflammation,and to provide reference for its clinical application.Methods 260 elderly patients with periapical inflammation were randomly divided into the experimental group and the control group.The experimental group was assisted by semiconductor laser to disinfect the root canal after conventional root canal preparation,while the control group was not assisted by semiconductor laser.The pain degree and efficacy of root canal treatment were compared at 24 h and 72 h after root canal preparation.Results The pain degree of the experimental group was less than that of the control group at 24 h and 72 h after root canal treatment(P<0.05).The success rate of six months and one year root canal treatment in the experimental group was higher than that in the control group(P<0.05).Conclusion In the process of root canal therapy for elderly patients with periapical inflammation,the application of semiconductor laser for root canal disinfection can reduce the degree of postoperative pain and improve the success rate of root canal therapy,which has certain clinical application value.
