iRoot BP Plus生物陶瓷材料和MTA在颌骨囊肿受累牙中的应用效果

探讨iRoot BP Plus生物陶瓷材料和MTA在颌骨囊肿受累牙手术中的应用效果。方法 选取上海市嘉定区中心医院口腔科2019年12月-2021年12月收治的90例颌骨囊肿患者为研究对象,采用随机数字表法分为iRoot BP Plus观察组、MTA观察组和对照组,各30例。iRoot BP Plus观察组予以iRoot BP Plus充填根管下1/3段,MTA观察组予以MTA充填根管下1/3段,对照组予以传统冷牙胶侧方加压充填法。比较三组患牙即刻根充情况和颌骨囊肿术后1年的远期临床疗效,并比较两观察组根管下1/3段充填操作时间。结果 三组患牙根管充填恰填率均为100.00%,差异无统计学意义（P ＞0.05）;iRoot BP Plus观察组根管下1/3充填操作时间短于MTA观察组（P＜0.05）;术后随访1年,iRoot BP Plus观察组治疗总有效率高于MTA观察组,但差异无统计学意义（P＞0.05）,两观察组治疗总有效率均高于对照组（P＜0.05）。结论 iRootBP Plus和MTA应用于颌骨囊肿手术前受累牙根管治疗临床效果均优于传统冷牙胶侧方加压充填法,iRootBP Plus与MTA临床效果相似,但iRoot BP Plus临床操作时间短且简单方便、即取即用,值得临床应用。

Application Effect of Bioceramic Material iRoot BP Plus and MTA in Offending Teeth ofJaw Cyst

To compare the clinical efficacy of bioceramic materials iRoot BP Plus and MTA in offending teeth ofjaw cyst. Methods A total of 90 patients with jaw cysts admitted to the Department of Stomatology, Shanghai Jiading DistrictCentral Hospital from December 2019 to December 2021 were selected as the research objects. They were divided into iRoot BPPlus observation group, MTA observation group and control group by random number table method, with 30 patients in each group.The iRoot BP Plus observation group was filled with iRoot BP Plus to fill the lower 1/3 of the root canal, the MTA observationgroup was filled with MTA to fill the lower 1/3 of the root canal, and the control group was filled with traditional cold lateralcondensation method. The immediate root filling of the affected teeth and the long-term clinical efficacy of the jaw cyst after 1 yearwere compared among the three groups, and the filling operation time of the lower 1/3 segment of the root canal was comparedbetween the two observation groups. Results The root canal filling rate of the three groups was 100.00%, and the difference wasnot statistically significant (P >0.05). The operation time of 1/3 root canal filling in iRoot BP Plus observation group was shorterthan that in MTA observation group (P <0.05). After 1 year of follow-up, the total effective rate of treatment in the iRoot BP Plusobservation group was higher than that in the MTA observation group, but the difference was not statistically significant (P >0.05).The total effective rate of treatment in the two observation groups was higher than that in the control group (P <0.05). ConclusionThe clinical effect of iRoot BP Plus and MTA in the treatment of root canal of offending teeth before jaw cyst surgery is better thanthat of traditional cold gutta-percha lateral pressure filling method. The clinical effect of iRoot BP Plus is similar to that of MTA,but iRoot BP Plus has short clinical operation time and is simple and convenient, ready to use, and is worthy of clinical application.
