简介：镍是正畸矫治器的主要成分，比所有其他金属的总和更容易引起过敏反应，并可在易感受试者中引发广泛的超敏反应。本研究的目的是比较使用固定矫治器的正畸患者尿液中镍的预处理和治疗水平。方法：收集21例正畸患者（女性12例，男性9例）在矫治器放置前和放置后2个月的尿液标本。采用原子吸收分光光度法对镍离子进行分析。结果进行描述性分析、学生t检验和重复测量的方差分析(P
Introduction: Nickel, a primary component of orthodontic appliances, causes more allergic reactions than all other metals combined and can initiate a wide range of hypersensitivity reactions in susceptible subjects. The purpose of this study was to compare pretreatment and treatment levels of nickel in the urine of orthodontic patients wearing fixed appliances. Methods: Urine specimens were collected from 21 orthodontic patients (12 female, 9 male) before placement of orthodontic appliances and 2 months after placement. Nickel ion analysis was carried out with atomic absorption spectrophotometry. The results were submitted to descriptive analyses, the Student t test, and ANOVA for repeated measurements (P
