目的 旨在比较新型生物陶瓷材料iRoot BP Plus与传统盖髓材料氢氧化钙在乳磨牙深龋间接盖髓治疗中的临床疗效.方法 选择 2020 年 7 月—2022 年 6 月在上海市静安区牙防所儿童口腔科就诊的儿童患者乳磨牙深龋 104 颗为研究对象.随机分为两组,分别接受化学固化氢氧化钙Dycal及iRoot BP Plus进行间接盖髓治疗,术后 6、12 个月定期随访,评估临床疗效及影像学结果,比较两组患者的临床疗效和修复性牙本质厚度.结果 治疗 12 个月后,iRoot BP Plus组治疗成功率(96.23%)高于Dycal组(82.35%),差异有统计学意义(χ2=5.289,P=0.021).iRoot BP Plus 组修复性牙本质厚度增加量((0.161±0.017)mm)大于Dycal组((0.143±0.023)mm),差异无统计学意义(P＞0.05).结论 iRoot BP Plus在乳磨牙深龋间接盖髓治疗有较好的临床预期,能一定程度促进修复性牙本质形成,提高乳磨牙深龋治疗的远期成功率.
The clinical efficacy of anew bioceramic material for indirect pulp capping of deep primary molar caries
Objective To compare the clinical efficacy of a new bioceramic material iRoot BP Plus and a traditional pulp capping material calcium hydroxide for indirect pulp capping of deep primary molar caries.Methods A total of 104 deep primary molar caries in children who visited the Department of Pediatric Stomatology of Jing'an District Dental Hospital from July 2020 to June 2022 were se-lected as the research objects.They were randomly divided into two groups,which were treated with chemically cured calcium hydroxide Dycal and iRoot BP Plus for indirect pulp capping respectively.The patients were followed up regularly at 6 months and 12 months after the operation for clinical efficacy and imaging detection.The clinical efficacy and reparative dentin thickness of the two groups were compared.Results After 12 months of treatment,the success rate of treatment in the iRoot BP Plus group(96.23%)was higher than that in the Dycal group(82.35%),and the difference was statistically significant(χ2=5.289,P=0.021).The increase in reparative dentin thickness in the iRoot BP Plus group((0.161±0.017),mm)was greater than that in the Dycal group((0.143±0.023),mm),and the difference was not statistically significant(P＞0.05).Conclusion The application of iRoot BP Plus in the indirect pulp cap-ping of deep primary molar caries has good expectations,which can promote the formation of reparative dentin to a certain extent and improve the long-term success rate of the treatment fordeep primary molar caries.
