前言：氢氧化钙作为一种传统的牙髓切断剂已经使用了很长一段时间，但存在一些缺点。IRoot BP Plus(加拿大温哥华Innovative Bioceramix Inc.)是一种新开发的即用型硅酸钙基生物活性陶瓷，具有优异的生物活性和密封能力。然而，iRoot BP Plus作为有复杂冠折的恒切牙的切髓材料是否显示出比氢氧化钙更好的优势尚不清楚。方法：本研究包括205颗有复杂冠折的恒切牙。对这些牙齿进行切髓治疗，并根据切髓材料分为两组(iRoot BP Plus组105颗，氢氧化钙组100颗)。在12至24个月的随访期内收集临床和放射学信息。通过X线片分析两组修复性牙本质桥的形成及牙髓管闭塞情况。结果：两组牙髓切断术后平均随访17.5+/-4.4个月(12-24个月)的召回成功率有显著差异，iRoot BP Plus组和氢氧化钙组分别为99%和93%。92.4%的iRoot BP Plus组和90%的氢氧化钙组有修复性牙本质桥，但差异无统计学意义。两组各有2颗患牙(2%)牙髓管闭塞。结论：本研究获得的成功率表明，iRoot BP Plus作为牙髓切断剂可以替代氢氧化钙治疗复杂的牙冠骨折。
Introduction: Calcium hydroxide has been used as a traditional pulpotomy agent for a long time but has some disadvantages. iRoot BP Plus (Innovative Bioceramix Inc, Vancouver, Canada) is a newly developed, ready-to-use calcium silicate based bioactive ceramic with excellent bioactivity and sealing ability. However, whether iRoot BP Plus shows superiority over calcium hydroxide as a pulpotomy material on permanent incisors with complicated crown fractures remains unknown. Methods: This research included 205 permanent incisors with complicated crown fractures. These teeth were treated with pulpotomy and divided into 2 groups according to the pulpotomy material (105 treated with iRoot BP Plus and 100 with calcium hydroxide). Clinical and radiographic information was collected during the 12- to 24-month follow-up period. The formation of reparative dentin bridges and pulp canal obliteration were analyzed using radiographs in both groups. Results: The success rates for recall in the average follow-up period of 17.5 +/- 4.4 months (12-24 months) after pulpotomy treatment were significantly different between the 2 groups, with 99% for the iRoot BP Plus group and 93% for the calcium hydroxide group. Reparative dentin bridges were observed in 92.4% of the iRoot BP Plus group and 90% of the calcium hydroxide group, but the difference was not significant. Pulp canal obliteration was observed in 2 teeth (2%) in each group. Conclusions: The success rates obtained in our study indicate that iRoot BP Plus as a pulpotomy agent can be a suitable alternative to calcium hydroxide to manage complicated crown fractures.
