The aim of this study was to evaluate knowledge, attitudes and practices (KAP) of Moroccan dentists about allergy to Nickel (Ni) during orthodontic treatment.
Dentists of two Moroccan cities (n = 553) were contacted and a questionnaire was distributed to those who have certified of partial or exclusive practice of orthodontics (N = 202). They were asked to specify the adverse reactions observed and the alloys frequently used. KAP about etiology, prevention and therapeutic management of allergic patients were also addressed.
Twenty-two percent of the dentists have reported at least one allergic patient reaction with more implication of fixed appliances. Eleven percent of adverse effects locations reported were mucosal area and facial skin near contact area and less than 5% was systemic eruption outside contact site. Only 34% of the respondents knew the Nickel allergy etiology.
Nickel-containing orthodontic alloys are generally used even in patient with suspected nickel allergy. It is very important to minimize corrosion factors and use nickel-free appliances in clinical practice.
本研究旨在评估摩洛哥牙医在正畸治疗期间对镍（Ni）过敏的知识、态度和实践（KAP）。
联系了摩洛哥两个城市的牙医（n = 553），并向那些已获得正畸部分或专门执业认证的牙医（N = 202）发放了问卷。要求他们明确观察到的不良反应以及经常使用的合金。还涉及了关于过敏患者病因、预防和治疗管理的KAP。
22%的牙医报告至少有一例过敏患者反应，其中固定矫治器的关联更大。报告的不良反应发生部位中，11%是黏膜区域和接触区域附近的面部皮肤，不到5%是接触部位以外的全身性皮疹。只有34%的受访者知道镍过敏的病因。
即使在疑似镍过敏的患者中，通常也会使用含镍正畸合金。在临床实践中尽量减少腐蚀因素并使用无镍矫治器非常重要。
