摘　　要：目的观察外伤冠折恒切牙采用Vitapex行活髓切断术的疗效。方法年轻恒切牙外伤患者58例,年龄7~11岁,患牙70颗,用Vitapex作盖髓剂行活髓切断术,定期复查,随访2年。结果 70颗患牙的2年总有效率为88.57%（62/70）;露髓孔小于或等于1 mm与大于1 mm的患牙有效率有差异,但无统计学意义（χ2=0.137,P=0.711）;对3个年龄段（7岁≤年龄〈8岁、8岁≤年龄〈9岁、9岁≤年龄〈11岁）的有效率两两比较,差异均无统计学意义（P〉0.05）;伤后2 h内就诊者,其治疗有效率明显高于超过24 h就诊者（χ2=3.889,P=0.049）。结论应用Vitapex作盖髓剂,对年轻恒切牙行活髓切断术切实有效,伤后就诊时间是影响术后疗效的主要因素。Objective To observe the clinical effect of pulpotomy with Vitapex in crown-fracture immature incisors.Methods Fifty-eight cases including 70 immature incisors were treated with partial pulpotomy and assessed clinically by 2 years＇ followed up.Results Sixty-two teeth（88.57%） were successfully treated.The successful ratio was associated with treated time point after trauma.Conclusion Vitapex was successful and effective for pulpotomy treatment in young permanent teeth with crown fracture.
