摘要: 目的: 分析青少年患者口腔正畸疗效的影响因素,并构建logistic回归模型。方法: 选择2019年1月—2023年12月收治的260例青少年口腔正畸患者,采用正畸同行评价(peer assessment rating,PAR)指数评估疗效。治疗结束满2年时,PAR指数较治疗刚结束时降低>5分为疗效不佳组(n=53),其余为疗效良好组(n=207)。采用二元logistic回归分析青少年口腔正畸患者疗效不佳的危险因素,并通过危险因素构建logistic回归模型。结果: 二元logistic回归分析显示,焦虑(OR=8.467,95%CI=2.800~25.609,P<0.001)、安氏Ⅱ类错(OR=9.624,95%CI=2.504~36.990,P=0.001)、安氏Ⅲ类错(OR=4.210,95%CI=1.146~15.467,P=0.030)、牙根形态异常(OR=5.927,95%CI=2.276~15.435,P<0.001)、口腔卫生较差(OR=2.943,95%CI=1.139~7.604,P=0.026)和患者依从性较差(OR=9.620,95%CI=3.047~30.376,P<0.001)是青少年口腔正畸患者疗效不佳的危险因素,保持器佩戴时间(OR=0.773,95%CI=0.691~0.864,P<0.001)是保护因素。使用危险因素构建logistic回归模型,Hosmer-Lemeshow拟合度检验显示,χ2=6.648,P=0.575,模型预测青少年口腔正畸患者疗效不佳的曲线下面积(area under the curve,AUC)为0.939,95%CI为0.908~0.971,敏感度、特异度分别为92.5%、83.6%,实际应用准确率为89.2%。结论: 青少年口腔正畸患者疗效与焦虑、错畸形类型、牙根形态异常、口腔卫生、依从性和保持器佩戴时间有关,通过危险因素构建的logistic回归模型具有较高预测价值。

Abstract: PURPOSE: To analyze the influencing factors of orthodontic efficacy in adolescent patients and construct a logistic regression model. METHODS: A total of 260 adolescent orthodontic patients treated from January 2019 to December 2023 were selected. The therapeutic effect was evaluated using the peer assessment rating (PAR) index. At the 2-year follow-up after treatment completion, patients with a reduction of more than 5 points in the PAR index compared with immediately post-treatment were assigned to the poor efficacy group (n=53), and the remaining patients were assigned to the favorable efficacy group (n=207). Binary logistic regression was used to analyze the risk factors for poor efficacy in adolescent orthodontic patients, and logistic regression model was constructed based on the risk factors. RESULTS: The binary logistic regression analysis showed that anxiety (OR=8.467, 95%CI=2.800-25.609, P<0.001), Angle Class Ⅱ malocclusion (OR=9.624, 95%CI=2.504-36.990, P=0.001), Angle Class Ⅲ malocclusion (OR=4.210, 95%CI=1.146-15.467, P=0.030), root morphology abnormalities (OR=5.927, 95%CI=2.276-15.435, P<0.001), poor oral hygiene (OR=2.943, 95%CI=1.139-7.604, P=0.026) and poor patient compliance (OR=9.620, 95%CI =3.047-30.376, P<0.001) were risk factors for poor treatment outcome in adolescent orthodontic patients, while retainer wearing time (OR=0.773, 95%CI=0.69-0.864, P<0.001) was a protective factor. A logistic regression model was constructed using the risk factors. The Hosmer-Lemeshow goodness-of-fit test showed that χ2=6.648, P=0.575. The area under the curve (AUC) of the model for predicting poor treatment outcomes in adolescent orthodontic patients was 0.939, with a 95%CI of 0.908-0.971. The sensitivity and specificity were 92.5% and 83.6%, respectively, and the practical application accuracy was 89.2%. CONCLUSIONS: The orthodontic efficacy of adolescent orthodontic patients is related to anxiety, types of malocclusions, abnormal root morphology, oral hygiene, compliance and duration of retainer wearing. A logistic regression model constructed through risk factors has high predictive value.
