摘要/Abstract

摘要： 目的探讨在年轻恒牙血运重建术中,iRoot BP Plus与无机三氧化物聚合物(MTA)两种不同材料的应用效果比较。方法选择我院接诊的年轻恒牙血运重建术患者100例(100颗患牙),根据患者使用填充材料情况,MTA组50例(50颗牙,失访2例),iRoot BP Plus组50例(50颗牙,失访1例),对比两组填充牙牙根发育、根管壁厚度与牙根长度、不同时刻旧根尖周指数(O-PAI)变化以及临床疗效、并发症。结果 iRoot BP Plus组发育分型优于MTA组(χ²=2.21,P<0.05);iRoot BP Plus组治疗后根管壁厚度及增长率、牙根长度测量结果以及增长率均高于MTA组(t=3.511、3.342、9.983、10.638,P均<0.05);iRoot BP Plus组治疗12个月、24个月O-PAI评级结果均低于MTA组(t=8.570、8.268,P<0.05);MTA组、iRoot BP Plus组治疗总有效率分别为89.80%、97.96%,差异有统计学意义(χ²=4.461,P<0.05);MTA组、iRoot BP Plus组并发症发生率分别为32.65%、6.12%,差异有统计学意义(χ²=20.854,P<0.05)。结论在年轻恒牙血运重建术中,iRoot BP Plus效果优于MTA,且更利于牙根发育和并发症的控制。

Abstract: Objective To compare the application of iRoot BP Plus and inorganic trioxide polymer (MTA) in immature permanent teeth with pulp revascularization. Methods A total of 100 patients (100 teeth) with pulp revascularization in our hospital were selected. According to the use of filling materials, there were 50 cases in MTA group (50 teeth, 2 cases lost to follow-up) and 50 cases in iRoot BP Plus group (50 teeth, 1 case lost to follow-up). The root development, root canal wall thickness and root length, old periapical index (O-PAI) changes at different time, clinical efficacy and complications were compared between the two groups. Results The developmental typing of iRoot BP Plus group was better than MTA group (χ²=2.21,P<0.05); the measurement results of root canal wall thickness, root length and growth rate in iRoot BP Plus group were higher than those in MTA group (t=3.511, 3.342, 9.983, 10.638, P<0.05). The O-PAI rating of iRoot BP Plus group at 12 months and 24 months was lower than that of MTA group (t=8.570, 8.268, P<0.05). The total effective rates of MTA group and iroot BP plus group were 89.80% and 97.96% respectively, and the difference was statistically significant (χ²=4.461,P<0.05). The incidence of complications in MTA group and iRoot BP Plus group were 32.65% and 6.12% respectively, with significant difference (χ²=20.854,P<0.05). Conclusion iRoot BP Plus has better effect than MTA on immature permanent teeth with pulp revascularization. Moreover, it is more conducive to root development and control of complications.
