The purpose of the present review was to present a detailed description of those current scientific results and opinions relative to the biocompatibility of dental amalgam. The first section of the percent review to the pulpar reactions caused by amalgam fillings, especially when no protective base has been used, while the second part concerns itself with the biocompatibility of the dental amalgam per se. Specifically, reference is made to: a) the adverse reactions due to amalgam fillings both on the patient's physiological system and on the dentist's employing the material under consideration. b) those investigation results bearing a relation on the amount of mercury liberated during the amalgam filling procedures, i.e., mixing, condensation, finishing and polishing and/or removal of old amalgam fillings. c) Liberation of mercury, as well as metallic ions in the patients mouth cavity during chewing and/or during the process of intrabuccal galvanization and corrosion, and d) on the amount of mercury traced in the blood and urine of the patient following amalgam fillings. No conclusive evidence on any adverse reactions on the patient's health, attributable to the liberation of mercury from amalgam fillings, could be presented by the scientific investigations under consideration. Moreover, the number of cases reported on toxic reactions due to dental amalgam is negligible compared to the immense number of amalgam fillings performed in practice. It merits mentioning in this connection, however, the fact that the total amount of mercury attained by the patient from any other source, in conjunction with that liberated from amalgam fillings, could by all means contribute to a number of toxic reactions on the patient's health in general. Conclusively, one could state without reservations, that dental amalgam fillings per se are by and large free of toxic reactions on the patient, based on current scientific observations. Mentioning is finally made on several simple but nevertheless imperative precautions for the safety of public health.
本综述的目的是详细描述目前关于牙科汞合金生物相容性的科学成果和观点。综述的第一部分讨论了汞合金填充物引起的牙髓反应，特别是在未使用保护基底的情况下，而第二部分则关注牙科汞合金本身的生物相容性。具体而言，涉及以下方面：a）汞合金填充物对患者生理系统以及使用该材料的牙医所产生的不良反应。b）与汞合金填充过程（即混合、压实、修整和抛光以及/或去除旧汞合金填充物）中释放的汞量相关的研究结果。c）在咀嚼过程中和/或口腔内发生电偶腐蚀过程中，患者口腔中汞以及金属离子的释放，以及d）汞合金填充后患者血液和尿液中检测到的汞含量。所考虑的科学研究未能提供确凿证据证明汞合金填充物释放的汞会对患者健康产生任何不良反应。此外，与实际进行的大量汞合金填充相比，报告的因牙科汞合金导致的毒性反应病例数量可以忽略不计。然而，在这方面值得一提的是，患者从任何其他来源获得的汞总量，加上从汞合金填充物中释放的汞，肯定可能对患者的整体健康造成一些毒性反应。总之，根据目前的科学观察，可以毫无保留地说，牙科汞合金填充物本身总体上对患者没有毒性反应。最后提到了一些简单但至关重要的公共卫生安全预防措施。
