MTA和iRoot BP plus治疗根尖孔未闭合恒牙根尖周炎的临床疗效分析

Clinical effects of iRoot BP plus and mineral trioxide aggregate in treatment of apical periodontitis with open apical permanent teeth

目的 探讨和比较生物陶瓷材料无机三氧化矿物凝聚体(mineral trioxide aggregate, MTA)和iRoot BP plus在成年根尖孔未闭合患牙形成根尖屏障中的临床应用效果。方法 将200颗根尖孔未闭合恒牙根尖周炎患牙随机分为两组,分别采用MTA和iRoot BP plus制备根尖屏障。比较两种生物陶瓷材料在制备根尖屏障时的操作时间,分析不同根尖孔破坏类型、根尖区病变范围、根尖区充填情况以及患者年龄段对治疗成功率的影响。结果 iRoot BP plus组制备根尖屏障的操作时间比MTA组短,差异有统计学意义(P<0.05);不同根尖孔破坏类型、根尖区病变范围、根尖区充填情况以及患者年龄段对治疗成功率并无显著影响(P>0.05)。结论 MTA和iRoot BP plus在治疗根尖孔未闭合恒牙根尖周炎的临床效果相似,但iRoot BP plus的操作性更好。

Objective To analyze and evaluate the clinical application effect of bioceramic material mineral trioxide aggregate and iRoot BP plus on the formation of apical barrier in adult teeth with incomplete apical foramen.MethodsA total of 200 permanent teeth with apical periodontitis whose apical foramen were not closed were randomly divided into two groups,and the apical barrier was prepared with MTA and iRoot BP plus,respectively.The operation time of MTA and iRoot BP plus and effects of different types of apical foramen destruction,lesion range of apical area,the filling of apical area and patients'age on the treatment success rate was analyzed and compared.Results The operation time of preparing apical barrier in iRoot BP plus group was shorter than that in MTA group,and the difference was statistically significant(P<0.05).However,different types of apical foramen destruction,lesion scope of apical area,filling of apical area and patients'age had no effect on the treatment success rate of the two groups(P>0.05).Conclusion The clinical effects of MTA and iRoot BP plus in the treatment of apical periodontitis of permanent teeth with unclosed apical foramen are similar,but the operation performance of iRoot BP plus is better.
