目的：评价无机三氧化聚合物(MTA)治疗根尖孔未闭合患牙的临床疗效。方法：选取根尖孔未闭合的恒前牙共24颗，用MTA进行根尖诱导成形术，术后6月复诊观察疗效。结果：术后X线片显示18颗患牙适充，6颗牙超充约1～2㎜，根管内充填物致密；19例病例在治疗后复诊期间无不适症状,原有窦道消失,1例原有窦道未消失。6个月后线片复查显示除1例外，其余根部开放处屏障封闭严密,原有根尖周稀疏区逐渐缩小，无新的暗影出现,成功率为95％。结论：MTA 治疗根尖孔未闭合患牙的周期短，疗效好。

목적：평개무궤삼양화취합물(MTA)치료근첨공미폐합환아적림상료효。방법：선취근첨공미폐합적항전아공24과，용MTA진행근첨유도성형술，술후6월복진관찰료효。결과：술후X선편현시18과환아괄충，6과아초충약1～2㎜，근관내충전물치밀；19례병례재치료후복진기간무불괄증상,원유두도소실,1례원유두도미소실。6개월후선편복사현시제1예외，기여근부개방처병장봉폐엄밀,원유근첨주희소구축점축소，무신적암영출현,성공솔위95％。결론：MTA 치료근첨공미폐합환아적주기단，료효호。
Obective:Evaluation of inorganic oxide,mineral trioxide aggregate (MTA) treatment was not closed with dental clinical curative effect . Methods:Selection of apical foramen was not closed permanent anterior teeth of a total of 24, with the MTA apexification, observation of curative effect of fol ow-up after June. Results:Postoperative X-ray showed 18 teeth suitable fil ing, 6 teeth fil ed about 1~2 mm, root canal fil ing density;19 cases were in treatment period without symptoms, the original sinus disappeared,1 patients with sinus tract during treatment, the original did not disappear.6 months after the X-ray examination showed that except in 1 cases, the remaining root opening barrier closed tight,,the original periapical rarefaction region gradual y reduced, no new shadow appears,,the success rate is 95%.Conclusions:MTA root tip was not closed with dental treatment cycle short, curative effect is good.
