摘要目的观察三氧化矿物聚合体（MTA）对根尖孔未闭合的年轻恒牙慢性根尖周炎的治疗效果。方法选择来我院就诊的根尖孔未闭合患有根尖周炎的年轻恒牙54颗,患者年龄不超过20岁。实验组用根尖屏障术封闭根尖开放区,对照组行常规根尖诱导成形术,两组术后定期复查,评价临床效果和X光片。结果经过术后0.5-2年的观察,实验组27位患者复诊时26例均表示患牙咀嚼功能良好,无不适主诉,1例无明显好转,有效率达96.3%。对照组27位患者,8例根尖无硬组织形成,冠根折2例,有效率为61.5%,对照组两者差异有统计学意义。结论 MTA治疗根尖孔未闭合的年轻恒牙根尖周炎效果较好,可减少复诊次数,减轻患者负担,可广泛应用。
