摘　　要：为了解iRoot BP Plus联合Er∶YAG激光在年轻恒牙活髓切断术中的应用效果,选取口腔科就诊的8~10岁前牙冠折患者进行活髓切断术,随机分为激光组和常规组,分别采用Er∶YAG激光和涡轮手机去髓,比较术后12个月活髓保存成功率、术中牙髓切断时间、止血时间和术中疼痛。对40名健康儿童分别进行激光去髓(20颗)和涡轮机去髓(20颗)。随访12个月后,激光组和常规组的成功率分别为85%和80%,两组成功率无统计学差异(P>0.05),术中牙髓切断时间Er∶YAG激光组长于常规组,止血时间Er∶YAG激光组短于常规组,差异有统计学意义(P<0.05),Er∶YAG激光组VAS/VPS评分低于常规组,差异具有统计学意义(P<0.05)。结果表明,Er∶YAG激光和涡轮机对年轻恒牙活髓切断术的疗效相似,但明显缩短了术中止血时间,缓解患者术中疼痛,鉴于其易操作和低成本,Er∶YAG激光可作为一种潜在的牙髓切断辅助技术。this study assesses the efficacy of iRoot BP Plus in conjunction with Er:YAG laser application in live pulpotomy for young permanent teeth.Patients aged 8-10 years with anterior crown fractures were selected and randomly assigned to either a laser group or a conventional group.The former underwent depulpation with Er:YAG laser,while the latter used a turbo handpiece.Postoperative success rates of live pulp preservation at 12 months,pulpotomy duration,hemostasis time,and intraoperative pain were compared between groups.Laser pulpotomy(20 teeth)and turbine pulpotomy(20 teeth)were each conducted on 40 healthy children.After a 12-month follow-up,the success rates for the laser and conventional groups were 85%and 80%respectively,indicating no statistically significant difference(P>0.05).However,the Er:YAG laser group exhibited longer pulp cutting time but shorter hemostasis time than the conventional group,with both parameters being statistically significant(P<O.05).Additionally,the VAS/VPS scores of the Er:YAG laser group were lower than those of the conventional group,implying less intraoperative pain(P<0.05).Despite similar overall efficacy between Er:YAG laser and turbine methods for live pulpotomy in young permanent teeth,the former offered significantly reduced intraoperative hemostasis time and patient discomfort.Given its ease of use and cost-effectiveness,Er:YAG laser represents a potentially beneficial supplementary technique for pulpotomy.
