Abstract

A case is reported of a 28-year-old female patient, with active orthodontic treatment, who was treated in the dental practice for aesthetic reasons. The diagnosis was gingival overgrowth, induced by orthodontic treatment, and maxillary exostosis. The treatment consisted of periodontal cosmetic surgery and removing the exostosis. During surgery, samples of gingiva, saliva and alveolar bone were obtained. Before take the samples, the patient signed an informed consent. Nickel concentrations in ng/mL were measured by atomic absorption spectrophotometry. The mean nickel concentration in the samples were: 986.4 ng/ml in saliva, 779.5 ng/ml in alveolar bone, and 620.5 ng/ml in the case of gingiva. The high accumulation of nickel observed in each sample type is of particular interest because exposure to metals contained in orthodontic appliances is currently an important public health problem in dentistry.

固定正畸器械患者牙龈、唾液和牙槽骨中镍的生物积累:一例报告

报告一例28岁女性患者，积极正畸治疗，谁是在牙科诊所治疗审美的原因。诊断为牙龈过度生长，由正畸治疗引起，上颌外生。治疗包括牙周美容手术和去除外植体。术中采集牙龈、唾液及牙槽骨标本。取样前，患者签署知情同意书。采用原子吸收分光光度法测定镍浓度(ng/mL)。样品中镍的平均浓度为:唾液中986.4 ng/ml，牙槽骨中779.5 ng/ml，牙龈中620.5 ng/ml。在每种样品类型中观察到的高镍积累特别令人感兴趣，因为暴露于正畸器具中所含的金属目前是牙科领域的一个重要公共卫生问题。
