无机三氧化复合物修补髓室底和根管穿孔的临床效果

A clinic study about repairing furcation and root perforations using mineral trioxide aggregate

目的:评价MTA用于髓室底和根管穿孔修补的临床价值。方法:髓室底穿孔12例,随机分为2组,分别用MTA和IRM(对照组)修补,进行根管治疗,术后3、6、12个月复查,拍平行投照X线片,双盲法评价穿孔处根周组织的变化。用χ2检验比较2组治疗效果。根管穿孔9例:用MTA修补并完成根管治疗。复查时间和方法同前。纵向观察MTA修补根管穿孔的效果。结果:MTA组和IRM组治疗髓室底穿孔的有效率12个月时分别为80%和75%,两者间无明显差异(P=0.722)。MTA修补根管穿孔的病例治疗均有效。结论:MTA治疗髓室底和根管穿孔时能取得很好的治疗效果,可提高穿孔牙齿预后。

Objective ：To evaluate the results of repairing furcation and root perforation using Mineral Trioxide Aggregate （MTA）. Methods：Cases with furcation perforations were divided into two groups randomly, MTA and IRM （control group） methods were adopted in present study. Cases that had root perforations were treated with MTA. Pretreatment, immediate posttreatment, and 1 year follow-up radiographs were evaluated in a double-blind manner to determine the presence or absence of any pathologic changes adjacent to the perforation site. Results ：21 cases were involved. The healing rate of furcation perforation in MTA group was higher （ 80% ） when compared with that in IRM group（75% ）. However, statistical analysis showed no significant difference in success rates between both groups（ P =0. 722 ）. The healing rate of root perforation using MTA was 100%. Conclusion： MTA provides an effective seal of furcation/root perforations, and promises in improving the prognosis of perforated teeth.
