Based on toxicological, clinical, and epidemiological knowledge, the present paper reviews the status regarding possible deleterious health effects from occupational exposure to metallic mercury (Hg) in dental practice. Symptoms from the central nervous system are among the health problems that most often are attributed to Hg exposure in dentists and dental nurses working with amalgam. Uncharacteristic symptoms of chronic low-level Hg vapor exposure including weakness, fatigue, and anorexia have been observed in numerous studies of dental personnel. It is crucial to protect both human health and the environment against negative effects of Hg. In line with this, the use of dental amalgam in industrial countries is about to be phased out. In Norway and Sweden, the use of the filling material is banned.

基于毒理学，临床和流行病学知识，本文综述了牙科实践中因职业性接触金属汞（Hg）可能产生的有害健康影响的现状。中枢神经系统症状是健康问题之一，最常见的原因是与汞齐一起工作的牙医和牙科护士中的汞暴露。在许多牙科人员的研究中已观察到慢性低水平汞蒸气暴露的异常症状，包括虚弱，疲劳和厌食。保护人类健康和环境免受汞的负面影响至关重要。与此相符，在工业化国家中，牙科用汞合金的使用将被逐步淘汰。在挪威和瑞典，禁止使用填充材料。
