摘要

目的 评估生物陶瓷材料 iRoot BP Plus 在乳磨牙深龋间接牙髓治疗中的临床疗效，并与矿物三氧化物凝聚体（MTA）和氢氧化钙进行比较，以验证其有效性与安全性。方法 选取2023年1月至2023年12月期间在本科室就诊的50例4～7岁乳磨牙深龋患儿，采用随机数字表法将其分为三组：iRoot BP Plus组（n=17）、MTA组（n=17）和氢氧化钙组（n=16）。所有患牙均接受标准化的间接盖髓治疗，分别使用三种材料进行盖髓。术后于第3、6、12个月进行临床及影像随访，观察指标包括临床成功率、牙根吸收程度、不良反应发生率及术中操作指标。结果 iRoot BP Plus组在3、6、12个月的随访中，临床成功率分别为100%、94.1%和94.1%，显著高于氢氧化钙组（P<0.05），与MTA组差异无统计学意义（P>0.05）。在牙根吸收程度方面，iRoot BP Plus组明显优于氢氧化钙组（P≤0.05）；不良反应发生率亦显著较低（P<0.05）。三组间的手术时间无显著差异，平均为（30±5）分钟，术中患儿疼痛感较轻。结论 iRoot BP Plus在乳磨牙深龋间接盖髓治疗中表现出良好的临床效果，具有较高的成功率、较低的根吸收风险及不良反应发生率，其疗效优于氢氧化钙。该材料具有良好的生物相容性和操作便捷性，是一种安全、有效的间接盖髓材料，具有广阔的临床应用前景。

Abstract

Objective To evaluate the clinical efficacy of the bioceramic material iRoot BP Plus in indirect pulp treatment (IPT) of deep caries in primary molars, and to compare its effectiveness and safety with mineral trioxide aggregate (MTA) and calcium hydroxide.
Methods A total of 50 children aged 4 to 7 years with deep caries in primary molars, who were treated in our department between January and December 2023, were selected. Using a random number table method, the patients were divided into three groups: iRoot BP Plus group (n=17), MTA group (n=17), and calcium hydroxide group (n=16). All patients underwent standardized indirect pulp treatment using the respective materials. Follow-ups were conducted at 3, 6, and 12 months post-treatment. Clinical evaluation indicators included success rate, degree of root resorption, incidence of adverse reactions, and operative parameters.
Results The clinical success rates in the iRoot BP Plus group at 3, 6, and 12 months were 100%, 94.1%, and 94.1%, respectively, which were significantly higher than those in the calcium hydroxide group (P<0.05), and not significantly different from the MTA group (P>0.05). The iRoot BP Plus group showed significantly less root resorption (P≤0.05) and a lower incidence of adverse reactions (P<0.05) compared to the calcium hydroxide group. No significant differences were observed in operative time among the three groups, with an average duration of 30±5 minutes. Children experienced mild intraoperative pain.
Conclusion   iRoot BP Plus demonstrates favorable clinical performance in the indirect pulp treatment of deep caries in primary molars, with high success rates, reduced root resorption, and fewer adverse effects. Its therapeutic efficacy is superior to calcium hydroxide and comparable to MTA. With good biocompatibility and ease of handling, iRoot BP Plus is a safe and effective pulp capping material with promising clinical application prospects.
