Er,Cr:YSGG水激光用于根管治疗约诊间疼痛的疗效观察

Clinical observation of using Er,Cr:YSGG water laser to control endondontic interappointment pain

目的 :探讨水激光在根管治疗中对于缓解根管治疗约诊间疼痛(endodontic interappointment pain,EIAP)的作用。方法:选择我院2015年6月—2017年6月接诊的慢性牙髓炎与根尖周炎患者272例,随机分为2组,每组136例。常规根管预备后,A组患牙在水激光处理后,封入氢氧化钙糊剂;B组封入氢氧化钙糊剂,2组均用caviton暂封窝洞,观察及比较2组患牙在术后不同时间下EIAP的发生及转归情况。采用SPSS 17.0软件包对数据进行统计学分析。结果:术后即刻及术后1周,2组间EIAP发生率无显著差异(P>0.05);术后1、2、3 d,A组EIAP发生率显著低于B组(P<0.05)。结论:水激光可有效减少根管治疗约诊间疼痛的发生率,且可有效缩短患者疼痛时间,值得推广应用。

PURPOSE:This study was to explore the role of Er,Cr:YSGG water laser in relieving endodontic interappointment pain(EIAP)during root canal therapy.METHODS:A total of 272 cases with chronic pulpitis and chronic periapical periodontitis were selected from the Department of Endodontics of our hospital from June 2015 to June2017,they were randomly divided into 2 groups,136 cases in each group.After routine root canal preparation,the teeth in group A were sealed with calcium hydroxide paste after Er,Cr:YSGG water laser treatment,while teeth in group B were sealed with calcium hydroxide paste.Caviton(GC company,Japan)was used for temporary fillings in both groups,occurrence and outcomes of postoperative EIAP were recorded and compared.SPSS 17.0 software package was used for statistical analysis.RESULTS:Among the two groups,there was no significant differences in EIAP(P>0.05)immediately and 1 week after surgery,but there was significant difference in the occurrence of EIAP between the first day,the second day and the third day after surgery(P<0.05).Group A had the lowest incidence of EIAP.CONCLUSIONS:Er,Cr:YSGG water laser can effectively reduce pain after root canal therapy,and can effectively shorten pain duration for patients;therefore,it is worthy of wide clinical application.
