摘　　要：目的:探究青少年正畸固定矫治后牙釉质脱矿影响因素及氟化物干预效果。方法:回顾性分析本院2020年3月至2021年3月收治的89例行正畸治疗患者的临床资料,依据治疗后是否发生牙釉质脱矿分为脱矿组(43例)与未脱矿组(46例),对比两组患者一般资料,采用多因素Logistic回归分析影响患者是否发生牙釉质脱矿的危险因素。依据43例脱矿患者采取的不同治疗方式分为A、B组,A组23例患者采用氟化物治疗,B组20例患者采取常规口腔卫生保护措施,比较两组患者临床疗效及正畸前、正畸后12个月釉质脱矿指数(Enamel Demineralization Index,EDI)、菌斑指数(Plaque index,PLI)、出血指数(bleeding index,BI)。结果:多因素Logistic回归分析结果显示,刷牙频率、是否使用含氟牙膏、甜食摄入及饮用碳酸饮料情况是影响正畸固定矫治后牙釉质脱矿的独立危险因素,P<0.05;A组治疗总有效率95.65%(22/23)显著高于B组70.00%(14/20),P<0.05;正畸后12个月,两组患者EDI(0.22±0.04)、PLI(0.22±0.04)、BI(1.47±0.35)水平均较正畸前上升且A组各项水平均低于B组(0.35±0.06、2.13±0.45、2.60±0.47),P<0.05。结论:青少年正畸固定矫治后常引起牙釉质脱矿,与患者的刷牙频率、是否使用含氟牙膏、甜食摄入及饮用碳酸饮料情况有关;采取氟化物治疗能够明显改善牙釉质脱矿,值得临床参考借鉴。Objective:To explore the influencing factors of enamel demineralization and the effect of fluoride intervention in adolescents after orthodontic treatment.Methods:The clinical data of 89 patients who received orthodontic treatment in our hospital from March 2020 to March 2021 were retrospectively analyzed.According to whether enamel demineralization occurred after treatment,they were divided into a demineralization group(43 cases)and a non-demineralization group.(46 cases),the general data of the two groups of patients were compared,and the multivariate Logistic regression analysis was used to analyze the risk factors affecting the occurrence of enamel demineralization in patients.According to the different treatment methods of 43 demineralized patients,they were divided into groups A and B.The 23 patients in group A were treated with fluoride,and the 20 patients in group B were treated with routine oral hygiene protection measures.The clinical efficacy and pre-orthodontic treatment were compared between the two groups,as well as 12 months after orthodontic treatment enamel demineralization index(Enamel Demineralization Index,EDI),plaque index(Plaque index,PLI),bleeding index(bleeding index,BI).Results:The results of multivariate Logistic regression analysis showed that the frequency of tooth brushing,the use of fluoride toothpaste,the intake of sweets,and the consumption of carbonated beverages were independent risk factors for enamel demineralization after orthodontic treatment,P<0.05;The total effective rate of group A was 95.65%(22/23),which was significantly higher than that of group B,70.00%(14/20),P<0.05;12 months after orthodontic treatment,the EDI of the two groups of patients was 0.22±0.04,PLI(0.22±0.04),BI(1.47±0.35)levels were higher than those before orthodontic treatment,and the levels in group A were lower than those in group B(0.35±0.06,2.13±0.45,2.60±0.47),P<0.05.Conclusion:Demineralization of tooth enamel often occurs after orthodontic treatment in adolescents,which is related to the frequ
