摘　　要：目的:探讨根管侧穿修补材(iRoot BP)与无机三氧化矿物凝聚体(MTA)治疗年轻恒牙意外露髓的近期及远期效果。方法:选取104例年轻恒牙意外露髓的患儿为研究对象,根据治疗方式不同分为iRoot BP组和MTA组,每组各52例。iRoot BP组患儿采用iRoot BP盖髓治疗;MTA选用MTA盖髓治疗。比较两组患儿盖髓操作时间、治疗结束3个月后临床疗效、术前及术后3个月患儿疼痛情况(VAS评分)、牙龈健康状况(GI及SBI评分)、治疗结束后随访1年填体不牢固或缺损、牙冠变色、牙髓活力异常、无牙本质桥形成及牙髓炎等发生情况。结果:iRoot BP组盖髓操作时间短于MTA组(P<0.05);治疗结束3个月后,临床疗效优于MTA组(P<0.05)。术前,两组患儿VAS、GI及SBI评分比较,差异无统计学意义(P>0.05);术后,iRoot BP组VAS、GI及SBI评分优于MTA组(P<0.05)。治疗结束后随访1年,两组患儿均无充填体不牢固或缺损现象发生,且牙髓活力异常、无牙本质桥形成及牙髓炎发生率比较,差异无统计学意义(P>0.05);MTA组牙冠变色发生率高于iRoot BP组(P<0.05)。结论:与MTA治疗相比,iRoot BP治疗能缩短年轻恒牙意外露髓患儿的盖髓操作时间,减轻疼痛,优化牙龈状况,且术后无牙冠变色情况出现,整体疗效更优。Objective:To compare and analyze short-term and long-term curative effect of iRoot BP and routine mineral trioxide aggregate(MTA)on accidental exposed pulp of young permanent teeth.Methods:104 children due to accidental exposed pulp of young permanent teeth were enrolled.They were divided into iRoot BP group and MTA group according to different treatment methods,52 cases in each group.MTA and iRoot BP were selected as pulp capping agents in MTA group and iRoot BP group,respectively.The time of pulp capping operation in single surgery of both groups was recorded.At 3 months after treatment,the clinical curative effect of both groups was evaluated.The scores of visual analogue scoring(VAS),gingival index(GI)and sulcus bleeding index(SBI)before surgery and at 3 months after surgery were recorded.They were followed up for 1 year after treatment.The non-fastness or defects of infills,teeth discoloration,abnormal pulp activity,formation of no dentine bridge and pulpitis after surgery were observed.Results:The operation time of pulp capping in iRoot BP group was significantly shorter than that in MTA group(P<0.05).3 months after treatment,the overall clinical curative effect in iRoot BP group was significantly better than that in MTA group(P<0.05).Before operation,there was no significant difference in VAS,GI and SBI scores between the two groups(P>0.05).After operation,all the above indexes in iRoot BP group were better than those in MTA group(P<0.05).After 1 year follow-up,there was no infilling or defect in the two groups,there were no significant difference in abnormal pulp activity,no formation of dentine bridge and pulpitis between the two groups(P>0.05).The incidence of tooth discoloration at 1 year after surgery in MTA group was significantly higher than that in iRoot BP group(P<0.05).Conclusion:Compared with routien MTA,the application of iRoot BP in the the treatment of accidental exposed pulp of young permanent teeth can shorten the operation time of pulp capping,alleviate pain,and optimize gingival status.Th
