[摘要] 目的 探讨MTA用于根管或髓室穿孔修补与根尖屏障的临床价价值。 方法 将2013年1月—2014年5月在该院牙体牙髓科治疗的80例根管穿孔或根尖敞开患者随机观察组与对照组两组，每组40例，均采用穿孔修补及根尖屏障，对照组给予氢氧化钙糊剂填充，观察组给予MTA填充，比较两组3个月、6个月后的治疗效果、疼痛发生率等。 结果 观察组3个月、6个月后的有效率分别为为95.65%、91.3%，明显高于对照组的86.96%、78.26%，差异有统计学意义（P<0.05）；观察组疼痛发生率为4.35%，明显低于对照组13.04%，差异有统计学意义（P<0.05）。结论 MTA是一种良好的牙体治疗材料，应用MTA填充的根尖屏障与穿孔修补术效果显著。

[Abstract] Objective To investigate the clinical value of MTA for perforation repair and apical barrier. Methods 80 patients with root canal or pulp chamber perforation who were treated in the Department of Tooth and Pulp of our hospital between January 2014 January and January 2015 were randomly divided into two groups， the control group and the observation group with 40 in each group. All of them received perforation repair and apical barrier. But those in the control groups adopted calcium hydroxide paste for root canal filling treatment， while those in the observation group were given MTA for root canal filling treatment. Treatment effects and the incidence of pain after 3 months and 6 months treatment of the two groups were compared. Results The effective rate after 3 months and 6 months treatment 95.65%， 91.3% of the observation group， were significantly higher than those of control group 86.96%， 78.26%， and the differences were statistically significant （P<0.05）； The the incidence of pain of the observation group， 4.35%， was significantly lower than that of the control group， 13.04%， and the difference was statistically significant （P<0.05）. Conclusion MTA is a kind of good dental Material， the application of which in perforation repair and apical barrier has remarkable effect.

髓室穿孔与根尖敞开是牙体牙髓科常见和多发的疾病类型之一，主要是由髓腔感染、根内外吸收、医源性根管侧穿及根折等引起的。如果髓室穿孔得不到及时、有效的修复，会进一步破坏牙体及牙周组织，最后只能行拔牙治疗[1]。而行早期治疗，采用修复材料封闭根管系统与根尖周组织间的通道治疗关键。MTA作为新型的牙体治疗中使用的修复性材料，具有较好的边缘封闭性能及生物相容性[2]，并能促进愈合反应。为探讨MTA用于根管或髓室穿孔修补与根尖屏障的临床价价值，该研究2013年1月—2014年5月将MTA应用于穿孔修补及根尖屏障，取得了较为满意的封闭效果，现报道如下。
