A clinic study about repairing furcation and root perforations using mineral trioxide aggregate / 实用口腔医学杂志

ABSTRACT

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 1year 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.
