摘要： 目的: 观察iRoot BP plus盖髓治疗恒牙深龋3年后的临床疗效,探讨此类治疗方法的可行性及影响因素。方法: 选取2019年1月至2020年9月于我科就诊,诊断为深龋或可复性牙髓炎成熟恒牙112颗,在牙科手术显微镜下选择性去龋后完成盖髓治疗,随访3年,通过影像学检查及临床指标评估患牙治疗效果。采用Kaplan-Meier生存分析统计活髓生存率,采用χ2检验分析各个变量对疗效的影响。结果: Kaplan-Meier生存曲线显示112例成熟恒牙盖髓术后3年生存率为91.1%,82例患牙行间接盖髓术,30例患牙去龋时露髓行直接盖髓术,3年生存率分别为92.7%与86.7%。盖髓疗效与性别、年龄、术前诊断、牙型(前牙、前磨牙、磨牙)、洞形(Ⅰ类洞、Ⅱ类洞、Ⅲ类洞)、牙位及盖髓方式无相关性(P>0.05)。结论: iRoot BP plus作为盖髓剂对诊断为深龋或可复性牙髓炎的成熟恒牙行盖髓治疗疗效良好,研究变量对预后均无显著影响。

Abstract: Objective: To observe the clinical efficacy of iRoot BP plus pulp capping treatment for deep caries of permanent teeth after 3 years, and to explore the feasibility and influencing factors of this treatment method. Methods: One hundred and twelve mature permanent teeth diagnosed with deep caries or reversible pulpitis were selected from our department from January 2019 to September 2020. The caries were selectively removed under a dental surgical microscope and pulp capping treatment was completed. The follow-up period was more than 3 years, and the treatment effect was evaluated through imaging examinations and clinical indicators. Kaplan Meier survival analysis was used to calculate the survival rate of live pulp, and χ2 test was used to examine the impact of various variables on clinical efficacy. Results: The Kaplan Meier survival curve showed that the 3-year survival rate of 112 mature permanent teeth after pulp capping was 91.1%, 82 affected teeth underwent indirect pulp capping, and 30 affected teeth underwent direct pulp capping after pulp exposure during caries removal. The 3-year survival rates were 92.7% and 86.7%, respectively. The efficacy of pulp capping was not correlated with gender, age, preoperative diagnosis, tooth type (anterior teeth, premolars, molars), cavity shape (Class Ⅰ, Ⅱ, Ⅲ), tooth position, and pulp capping method (P>0.05). Conclusion: iRoot BP plus as a pulp capping agent has a good therapeutic effect on mature permanent teeth diagnosed with deep caries or reversible pulpitis, and the study variables have no significant impact on prognosis.
