摘要： 目的: 分析正畸治疗前后唾液流速、总蛋白变化及与牙菌斑的关系。方法: 回顾性分析2021年5月—2024年2月淮北矿工总医院80例正畸患者的临床资料,比较治疗前后唾液流速、总蛋白水平。治疗后6个月,以牙菌斑指数中位数将患者分为低水平组（n=39）和高水平组（n=41）,比较高水平组与低水平组的临床资料,分析正畸患者高牙菌斑指数的影响因素。分析△唾液流速（治疗前唾液流速-治疗后6个月唾液流速）、△总蛋白及两者联合对正畸患者高牙菌斑指数的预测价值。采用SPSS 25.0软件包对数据进行统计学分析。结果: 治疗后6个月,患者唾液流速、总蛋白水平显著低于治疗前（P<0.05）。高水平组软垢指数、△唾液流速和△总蛋白水平显著高于低水平组（P<0.05）。Logistic回归分析结果显示,△唾液流速（OR=4.604,95%CI：2.024~10.474）、△总蛋白（OR=3.554,95%CI：1.562~8.084）是高牙菌斑指数的影响因素（P<0.05）。△唾液流速、△总蛋白及两者联合预测正畸患者高牙菌斑指数的曲线下面积（area under the curve,AUC）分别为0.803、0.799和0.905（P<0.05）,且两者联合的AUC值更高（P<0.05）。结论: △唾液流速、△总蛋白可用于预测正畸治疗后高牙菌斑指数,两者联合具有更高的预测价值。

Abstract: PURPOSE: To analyze the relationship between the changes of saliva flow velocity, total protein and dental plaque before and after orthodontic treatment. METHODS: The clinical data of 80 patients who received orthodontic treatment in Huaibei Miners General Hospital from May 2021 to February 2024 were retrospectively analyzed.Six months after treatment, the patients were divided into low-level group (n=39) and high-level group (n=41) according to the median plaque index. The clinical data of the high-level group and the low-level group were compared to analyze the influencing factors of high dental plaque index in orthodontic patients. The predictive value of △saliva flow velocity(before treatment -after 6 months of treatment), △total protein and their combination on high dental plaque index in orthodontic patients was analyzed.SPSS 25.0 software package was used for statistical analysis of the data. RESULTS: Six months after treatment, the saliva flow velocity and total protein level of orthodontic patients were significantly lower than before treatment (P<0.05). The soft scale index, △saliva flow velocity and △total protein level in high-level group were significantly higher than those in low-level group (P<0.05). Logistic regression analysis showed that △saliva flow velocity(OR=4.604, 95%CI: 2.024-10.474) and △ total protein(OR=3.554, 95%CI: 1.562-8.084) were the influencing factors of high dental plaque index (P<0.05).The area under the curve (AUC) of △ saliva flow velocity, △total protein and their combination in predicting high dental plaque index in orthodontic patients were 0.803, 0.799 and 0.905 (P<0.05), respectively, and the AUC value of the combination was higher(P<0.05). CONCLUSIONS: △Saliva flow velocity and △total protein can be used to predict high dental plaque index after orthodontic treatment, and their combination has higher predictive value.
