摘　　要：目的:评价生物陶瓷iRoot BP Plus用于年轻恒牙牙髓切断术的临床效果。方法:选择因复杂冠折就诊的7~12岁儿童39例,随机分组,牙髓切断术中分别应用iRoot BP Plus(试验组,22颗)和氢氧化钙类制剂(对照组,19颗)盖髓,术后1、3、6、12个月复查,观察术后症状、钙化桥形成及牙根发育等,计算两组患儿临床及影像学成功率。结果:试验组术后12个月临床及影像学成功率均为100.0%,对照组术后6个月成功率为100.0%,术后12个月成功率为94.1%,两组比较差异无统计学意义。试验组术后3个月内均形成钙化桥。结论:iRoot BP Plus作为盖髓剂用于年轻恒牙牙髓切断术可取得良好的疗效,良好的操作性能可提高椅旁诊疗效率。Objective:To determine the clinical efficacy of the newly developed iRoot BP Plus applied in pulpotomy for immature permanent teeth.Methods:Forty-one teeth in 39 children(aged 7– 12 years)with complicated crown fracture were randomly treated with either iRoot BP Plus(n=22)or calcium hydroxide(CH,n=19)as pulpotomy medicaments.Clinical and radiographic follow-up examinations were conducted at 1,3,6 and 12 months postoperatively.Results:The 12-month clinical and radiographic success rates of iRoot BP Plus were 100.0%.The 6-month clinical and radiographic success rates of CH group were 100.0%,the 12-month success rates were 94.1%.The rates did not differ significantly between two groups.All teeth of iRoot BP Plus group showed the formation of calcified bridge in 3 months.Conclusion:The success rates of iRoot BP Plus and calcium hydroxide are indistinguishable,indicating that pulpotomy can be carried out successfully in immature permanent teeth with the new ready-to-use bioceramic.
