摘要
目的探讨外伤性冠折露髓的年轻恒牙行部分活髓切断术中应用盖髓剂iRoot BP Plus和矿物三氧化聚合体(mineral trioxide aggregate, MTA)的效果。方法外伤性恒前牙冠折露髓患者109例(153颗牙)均行部分活髓切断术,根据术中使用的盖髓剂分为氢氧化钙组38例(52颗牙),MTA组36例(51颗牙),iRoot BP Plus组35例(50颗牙)。术后随访观察临床成功、影像学成功情况,比较术后12个月3组治疗总成功率;记录并比较术后1、3、6个月钙化桥形成率,观察术后12个月3组牙齿变色情况。结果术后12个月,iRoot BP Plus组治疗总成功率(100.00%)高于氢氧化钙组(92.31%)(P<0.05),与MTA组(98.04%)比较差异无统计学意义(P>0.05);MTA组与氢氧化钙组比较差异无统计学意义(P>0.05)。术后1个月,3组钙化桥形成率比较差异无统计学意义(P>0.05);术后3个月iRoot BP plus组钙化桥形成率(62.00%)高于MTA组(45.10%)、氢氧化钙组(40.38%)(P<0.05),MTA组与氢氧化钙组比较差异无统计学意义(P>0.05);术后6个月时,3组钙化桥形成率均为100%。术后12个月,氢氧化钙组有1例牙冠变色,MTA组牙齿充填部位均变色,iRoot BP Plus组未见牙齿变色。结论治疗因外伤复杂冠折露髓的年轻恒牙时,iRoot BP Plus和MTA均可替代氢氧化钙,iRoot BP Plus在促进钙化桥形成、防止牙齿变色上更具有优势。
Objective To investigate the clinical effect of iRoot BP Plus versus mineral trioxide aggregate(MTA) as pulp cap in partial medullotomy of young permanent teeth with traumatically fractured crown and exposed pulp. Methods Totally 109 patients(153 teeth) with traumatically fractured crown and exposed pulp were treated with partial pulpotomy, and were divided into calcium hydroxide group(38 patients, 52 teeth), MTA group(36 patients, 51 teeth), and iRoot BP Plus group(35 patients, 50 teeth) according to the pulp capping agent used. The clinical and imaging success rate were followed up, and the total clinical success rate was compared among three groups. The calcification bridge formation rate was recorded and compared 1, 3 and 6 months after surgery, and the discoloration of teeth was observed 1 year after surgery. Results The total clinical success rate was higher in iRoot BP Plus group(100.00%) than that in calcium hydroxide group(92.31%)(P<0.05), and showed no significant difference between MTA group(98.04%) and iRoot BP Plus group(P>0.05). One month after surgery, there was no significant difference in the calcification bridge formation rate among three groups(P>0.05). Three months after surgery, the calcified bridge formation rate was higher in iRoot BP Plus group(62.00%) than that in MTA group(45.10%) and calcium hydroxide group(40.38%)(P<0.05), and showed no significant difference between MTA group and calcium hydroxide group(P>0.05). Six months after surgery, the calcification bridge formation rate was 100% in all three groups. Twelvemonths after surgery,tooth discoloration occurred in 1 case in calcium hydroxide group,in all filling sites in MTA group,and in none case in iRoot BP Plus group.Conclusions Both iRoot BP Plus and MTA can replace calcium hydroxide in the treatment of young permanent teeth with complex traumatically fractured crown and exposed pulp.IRoot BP Plus has more advantages in promoting the formation of calcification bridge and preventing tooth discoloration.
