iRoot BP Plus在根管内血运重建术中的效果研究

目的观察iRoot BP Plus在根管内血运重建术中的治疗效果。方法选取接受治疗的80例年轻恒牙牙髓坏死患者为研究对象,随机分为观察组(n=40)与对照组(n=40)。2组均行根管内血运重建术,对照组采用矿物三氧化聚合体(MTA)封闭根管上段,观察组采用iRoot BP Plus封闭根管上段。观察2组患者6个月后的治疗总有效率,比较6、12个月牙本质表面牙骨质样组织沉积率。结果治疗6个月后,观察组治愈20例,好转13例,无效7例,总有效率为82.5%。对照组治疗6个月后治愈17例,好转11例,无效12例,总有效率为70.0%。观察组总有效率高于对照组,差异有统计学意义(P<0.05)。治疗后6、12个月,观察组牙本质表面牙骨质样组织沉积率均高于对照组,差异有统计学意义(P<0.05)。结论iRoot BP Plus应用于根管内血运重建术治疗年轻恒牙牙髓坏死可获得更好的治疗效果,可作为治疗年轻恒牙的牙髓坏死的新选择。

Effect of iRoot BP Plus in endodontic revascularization of root canal

Objective To observe the effect of iRoot BP Plus in endodontic revascularization of root canal.Methods A total of 80 patients with young permanent tooth pulp necrosis were enrolled in the study,and were randomly divided into observation group(n=40)and control group(n=40).The root canal revascularization was performed in both groups.The control group used mineral trioxide aggregate(MTA)to seal the upper part of the root canal,while the observation group used iRoot BP Plus to fill the upper part of the root canal.The treatment efficiency of the two groups after 6 months was observe,the deposition rates of dentin-like cementum-like tissue at 6 months and 12 months were compared.Results In the observation group,20 cases were cured after 6 months of treatment,13 cases were improved,and 7 cases were not effective,with total effective rate of 82.5%.In the control group,17 patients were cured after 6 months of treatment,11 patients were improved,and 12 cases were in valid,with total effective rate of 70.0%.The effective rate of the observation group was significantly higher than that of the control group(P<0.05).At 6 months and 12 months after treatment,the deposition rates of dentin-like tissue in the dentin surface of the observation group were significantly higher than those of the control group(P<0.05).Conclusion iRoot BP Plus has better efficacy in the treatment of young permanent teeth pulp necrosis by root canal revascularization,and it can be used as a new choice for young permanent teeth with pulp necrosis.
