光动力疗法对儿童活髓切断术联合预成冠术后疼痛缓解的临床观察

Clinical Effect of Photodynamic Therapy on Promoting Pain Relief after Pulpotomy Combined with Pre-crown Surgery in Children

目的:观察光动力疗法(PDT)对儿童活髓切断术联合不锈钢预成冠(SSC)戴冠后疼痛缓解的影响。方法:选择采用SSC修复患牙30对,分为实验组和对照组,采用自体口内对照,分别在修复后6、24、72 h回访患儿口腔疼痛情况,采用SPSS 20.0软件对数据进行统计分析。结果:儿童SSC修复后6 h,对照组和实验组的疼痛发生率分别为20%和10%,术后24 h两组疼痛发生率分别为60%和56.67%,实验组疼痛评分和疼痛程度均低于对照组,且差异具有统计学意义(P<0.05)。术后72 h两组疼痛评分和疼痛程度的差异无统计学意义(P>0.05)。结论:活髓切断术联合SSC术后进行光动力干预,可以有效缓解术后疼痛症状。

Objective:To learn the effect of photodynamic therapy(PDT)on promoting pain relief after pulpotomy combined with stainless steel preformed crowns(SSC)in children.Methods:Thirty pairs of teeth restored with SSC were selected,which were divided into photodynamic therapy and control groups,using an autologous tooth as the control.The children were followed up at 6 h,24 h,and 72 h after restoration.Results:At 6 h after SSC,the incidence of pain was 20%and 10%in the control group and the experimental group,respectively,and the incidence of pain was 60%and 56.67%in the two groups at 24 h after surgery,respectively,and the pain scores and pain levels in the experimental group were lower than those in the control group(P<0.05).However,the differences between the two groups were not statistically significant at 72 h after surgery(P>0.05).Conclusion:Photodynamic interventions after SSC can effectively relieve post-operative pain symptoms.
