口腔显微镜下生物陶瓷Iroot BP Plus联合热牙胶充填技术治疗慢性根尖周炎根尖未闭合的效果

Effect of oral microscopic biological ceramics Iroot BP Plus combined with warm gutta-percha obturation in treatment of chronic periapical periodontitis with apical non-closure

目的观察慢性根尖周炎根尖未闭合经口腔显微镜下生物陶瓷Iroot BP Plus联合热牙胶充填技术的治疗效果。方法选择2017年3月~2018年3月青海省西宁市口腔医院收治的慢性根尖周炎根尖未闭合患者120例,根据随机数字表法分为对照组与研究组,每组60例。两组均接受口腔显微镜下生物陶瓷Iroot BP Plus根尖屏障术治疗,研究组在此基础上联合热牙胶垂直加压充填术。术后1年评价临床疗效;比较两组操作时间、疼痛持续时间;分别于治疗前、治疗2周后,检测龈沟液炎性因子水平;比较两组患牙保留率。结果研究组治疗总有效率高于对照组,患牙保留率高于对照组(P<0.05)。两组操作时间比较,差异无统计学意义(P>0.05)。研究组术后疼痛持续时间短于对照组(P<0.05)。治疗前两组龈沟液炎性因子比较,差异无统计学意义(P>0.05);治疗2周后,两组龈沟液炎性因子水平低于治疗前,且研究组低于对照组(均P<0.05)。结论口腔显微镜下生物陶瓷Iroot BP Plus联合热牙胶充填技术治疗慢性根尖周炎根尖未闭合,可缩短患者术后疼痛持续时间,提高患牙保留率,患者根尖炎症消除效果好。

Objective To observe the efficacy of oral microscopic biological ceramics Iroot BP Plus combined with warm gutta-percha obturation in treatment of chronic periapical periodontitis with apical non-closure.Methods From March 2017 to March 2018,120 cases with chronic periapical periodontitis with apical non-closure who admitted in Xining Stomatological Hospital were selected.They were divided into control group and research group by random number table method,with 60 cases in each group.Both groups were received oral microscopic biological ceramics Iroot BP Plus apical barrier surgery,and on this basis,research group was treated with vertical condensation of warm gutta-percha obturation.Clinical efficacy was evaluated 1 year after surgery.Operation time and pain duration were compared between two groups.The levels of inflammatory factors in gingival crevicular fluid were measured before and 2 weeks after treatment.Retention rates of affected teeth were compared between the two groups.Results The total effective rate of research group was higher than that of control group,the retention rate of affected teeth in research group was higher than that in control group(P<0.05).There was no statistical difference in the operation time between two groups(P>0.05).The pain duration in research group was shorter than that in control group(P<0.05).There was no significant difference in the inflammatory factors of gingival crevicular fluid between two groups before treatment(P>0.05).After 2 weeks of treatment,the levels of inflammatory factors of gingival crevicular fluid in two groups were lower than those before treatment,and research group was lower than control group(all P<0.05).Conclusion Oral microscopic biological ceramics Iroot BP Plus combined with warm gutta-percha obturation in treatment of chronic periapical periodontitis with apical non-closure can shorten pain duration,increase the retention rate of affected teeth,and have better relief effects of apical inflammation.
