A diagnosis of chronic lead poisoning in a mentally retarded adult with pica was initially proposed because of the presence of a "lead line" on the patient's gingiva. The patient had no other signs or symptoms suggestive of her toxic state. Lead poisoning is reviewed from the standpoint of epidemiology, pathophysiology, clinical and oral manifestations, and diagnostic procedures. Dentists working with children or mentally retarded patients should be aware of the increased incidence of lead poisoning in these patient populations and the importance of oral findings and lead-screening techniques in the detection of lead poisoning.
一名患有异食癖的智障成年人因牙龈上出现“铅线”而最初被诊断为慢性铅中毒。该患者没有其他提示其中毒状态的体征或症状。本文从流行病学、病理生理学、临床和口腔表现以及诊断程序的角度对铅中毒进行了综述。诊治儿童或智障患者的牙医应意识到这些患者群体中铅中毒发生率的增加，以及口腔检查结果和铅筛查技术在铅中毒检测中的重要性。
