MTA对根尖孔未闭合的年轻恒牙慢性根尖周炎的治疗效果

Effect of MTA on chronic apical periodontitis of young permanent teeth with unclosed apical foramen

目的分析年轻恒牙根尖孔未闭合慢性根尖周炎应用三氧化矿物聚合体(MTA)治疗的效果。方法择取2015年7月至2016年8月接收的根尖孔未闭合年轻恒牙慢性根尖周炎患者123例作为研究对象,按数字奇偶法将其分为对照组和研究组,对照组(60例)给予Vitapex糊剂治疗;研究组(63例)给予MTA治疗,观察两组患者治疗总有效率以及根管治疗期间痛(EIP)的总发生率。结果研究组治疗总有效率显著高于对照组,EIP总发生率显著低于对照组(P<0.05)。结论对根尖孔未闭合年轻恒牙慢性根尖周炎患者应用MTA治疗,临床疗效显著,治疗中EIP发生率较低。

Objective To analyze the effect of mineral trioxide aggregate （MTA） on chronic apical periodontitis of youngpermanent teeth with unclosed apical foramen. Methods A total of 123 patients with chronic apical periodontitis of youngpermanent teeth with unclosed apical foramen were selected from July 2015 to August 2016 as research objects. They weredivided into control groups and study groups according to digital parity method. 60 patients in the control group were treatedwith Vitapex paste. 63 patients in the study group were treated with MTA. The total effective rate of treatment and the totalincidence of endodontic interappointment pain （EIP） were observed in the two groups. Results The total teffective rate oftreatment in the study group was significantly higher than that in the control group, the total incidence of EIP wassignificantly lower than that in the control group （P〈0.05）. Conclusion MTA is effective in the treatment of chronic apicalperiodontitis in young permanent teeth with unclosed apical foramen. The incidence of EIP in the treatment is lower.
