摘　　要：目的:探讨iROOT BP Plus用于年轻恒牙活髓切断术的临床疗效。方法:将120例因外伤冠折露髓的年轻恒前牙进行活髓切断随机分为3组,A组40例采用iROOT BP Plus盖髓,B组40例采用MTA盖髓,C组40例采用氢氧化钙盖髓;随后所有患者均进行冠外形恢复。结果:术后随访3个月3组治疗成功率和牙本质桥形成率无明显差异(P>0.05)。随访6个月3组治疗成功率和牙本质桥形成率差异有统计学意义(P<0.05);A组和B组均较C组高;B组牙齿变色发生率较A组和C组高(P<0.05)。结论:iROOT BP Plus用于年轻恒牙活髓切断,疗效可靠,术后美观度更高。Objective:To investigate the clinical effectiveness of iROOT BP Plus used as pulp capping agents in pulpotomy for young permanent teeth.Methods:Totally 120 young permanent anterior teeth were treated by pulpotomy due to traumatic crown fracture.They were randomly divided into 3 groups,that 40 cases in group A covered with iROOT BP Plus,40 cases in group B with MTA and 40 cases in group C with calcium hydroxide.Results:There was no significant difference among three groups in the success rate and the formation rate of dentin bridge in the 3-month follow-up(P>0.05).There was statistically significant difference in the success rate and the formation rate of dentin bridge in the 6-month follow-up(P<0.05).And that both group A and group B were higher than group C respectively.The incidence of tooth discoloration in group B was higher than that in group A and C respectively(P<0.05).Conclusion:iROOT BP Plus can be used to cut the living pulp of young permanent teeth with reliable curative effect and higher postoperative aesthetics.
