摘　　要：目的:研究Pulpdent Multi-Cal(PMC)盖髓剂用于活髓切断术的临床可操作性和疗效,为临床应用提供参考依据。方法:对因冠折露髓到北京大学口腔医院急诊科就诊患者的上颌年轻恒前牙25颗(20例患者)进行活髓切断术,用PMC盖髓剂作为活髓保存剂,观察临床可操作性和操作时间,术后对患牙进行定期随访观察,复诊时记录患牙的临床检查和X线片检查情况,并与采用北京大学口腔医院自制制剂进行活髓切断术的患牙进行比较。结果:随访6～15个月(中位时间12个月),25颗患牙(20例患者)均于1～3个月间在X线片上观察到钙化桥的形成并持续增厚,牙根继续发育,无根内外吸收和根管钙化出现。应用PMC盖髓剂活髓切断术中操作时间显著缩短(P<0.01),术后牙根长度的发育与正常的中切牙差异无统计学意义(P>0.05)。结论:使用PMC盖髓剂进行活髓切断术取得了较满意的疗效,可以作为一种成品制剂应用于临床活髓切断术的常规治疗,有助于缩短临床操作时间、控制感染,也可为研究年轻恒牙活髓保存技术和新型盖髓剂提供统一的参照标准。Objective：To investigate the clinical characteristics and prognosis of pulpotomy with Pulpdent Multi-Cal（PMC） in young permanent incisors.Methods： Twenty-five young permanet incisors with vital pulps and complicated crown fractures were treated by pulpotomy with PMC at the Emergency Department of Peking University School and Hospital of Stomatology.The teeth were checked clinically and radiographically during fixed intervals.Healing of the pulp was considered to have taken place if the following criteria were met： absence of clinical symptoms,absence of apical radiolucency,continued root development in immature teeth,radiographic evidence of dentin bridge formation,and positive response to pulp vitality tests.The results were compared with the teeth which underwent pulpotomy with preparation made by our hospital.Results： Followed up for 6-15 months（median 12 months）,on basis of the criteria for pulp healing,all teeth got successful treatment.And all the teeth showed radiographic evidence of dentin bridge formation within 1 to 3 months after pulpotomy.The operation time of PMC pulpotomy was significantly shortened（P0.01）.The root length of teeth performed with PMC pulpotomy and normal teeth had no significant difference（P0.05）.Conclusion： PMC is an acceptable material when used in pulpotomy of young permanent teeth.
