摘　　要：目的构建早期牙髓炎患者iRoot BP Plus活髓切断术后失败的个体化预测模型。方法选取2019年1月至2021年12月于秦皇岛市海港医院进行iRoot BP Plus活髓切断术治疗的278例早期牙髓炎患者为研究对象,记录性别、年龄、穿髓孔直径等资料并进行统计学分析,Logistic回归分析确定危险因素,绘制列线图预测模型,进行内部验证并评估临床预测效能及实用性。结果278例早期牙髓炎iRoot BP Plus活髓切断术后失败率为10.43%。将穿髓孔直径、腐质颜色、腐质质地提取为预测因子构建列线图预测模型,列线图预测模型的校正曲线与原始曲线及理想曲线接近,C-index为0.768(95%CI:0.722~0.833),模型拟合度高;列线图预测模型的阈值>0.16,可提供临床净收益,且临床净收益均高于独立预测因子。结论以穿髓孔直径、腐质颜色、腐质质地为预测因子构建的早期牙髓炎患者iRoot BP Plus活髓切断术后失败的列线图预测模型对iRoot BP Plus活髓切断术后失败的发生具有良好的预测价值。Objective To construct an individualised prediction model for failure after iRoot BP Plus pulpotomy in patients with early pulpitis.Methods A total of 278 patients with early pulpitis treated with iRoot BP Plus live pulpotomy in our hospital from January 2019 to December 2021 were selected for the study.Data on gender,age and pulp hole diameter were recorded and statistically analyzed,Logistic regression analysis was performed to identify risk factors,a line graph prediction model was drawn,internal validation was performed and clinical predictive efficacy and practicality was evaluated.Results The incidence of failure after iRoot BP Plus live pulpotomy in 278 cases of early pulpitis was 10.43%.The diameter of the medullary foramen,humus color,and humus texture were extracted as predictive factors to construct a column chart prediction model.The calibration curve of the line graph prediction model was close to the original curve and the ideal curve with a C-index of 0.768(95%CI:0.722-0.833),which was a good model fit.The threshold of the column chart prediction model was greater than 0.16,which can provide clinical net benefits,and the clinical net benefits were all higher than the independent predictive factors.Conclusion A line graph prediction model for failure after iRoot BP Plus pulpotomy in patients with early pulpitis,using pulp hole diameter,decay colour and decay texture as predictors,has good predictive value for the occurrence of iRoot BP Plus pulpotomy failure.
