Approximately 50% of dental amalgam is elemental mercury by weight. Accumulating body of evidence now shows that not only static magnetic fields (SMF) but both ionizing and non-ionizing electromagnetic radiations can increase the rate of mercury release from dental amalgam fillings. Iranian scientists firstly addressed this issue in 2008 but more than 10 years later, it became viral worldwide.
This review was aimed at evaluating available data on the magnitude of the effects of different physical stressors (excluding chewing and brushing) on the release of toxic mercury from dental amalgam fillings and microleakage.
The papers reviewed in this study were searched from PubMed, Google Scholar, and Scopus (up to 1 December 2019). The keywords were identified from our initial research matching them with those existing on the database of Medical Subject Headings (MeSH). The non-English papers and other types of articles were not included in this review.
Our review shows that exposure to static magnetic fields (SMF) such as those generated by MRI, electromagnetic fields (EMF) such as those produced by mobile phones; ionizing electromagnetic radiations such as X-rays and non- Ionizing electromagnetic radiation such as lasers and light cure devices can significantly increase the release of mercury from dental amalgam restorations and/or cause microleakage.
The results of this review show that a wide variety of physical stressors ranging from non-ionizing electromagnetic fields to ionizing radiations can significantly accelerate the release of mercury from amalgam and cause microleakage.
按重量计算，约50%的牙科汞合金是元素汞。越来越多的证据表明，不仅静磁场（SMF），而且电离和非电离电磁辐射都能增加牙科汞合金填充物中汞的释放速率。伊朗科学家在2008年首次提出了这个问题，但十多年后，它在全球范围内迅速传播。
本综述旨在评估不同物理应激源（不包括咀嚼和刷牙）对牙科汞合金填充物中有毒汞释放和微渗漏影响程度的现有数据。
本研究中综述的论文从PubMed、谷歌学术和Scopus（截至2019年12月1日）中检索。关键词是从我们最初的研究中确定的，并与医学主题词表（MeSH）数据库中现有的关键词进行匹配。非英文论文和其他类型的文章不包括在本综述中。
我们的综述表明，暴露于静磁场（如MRI产生的磁场）、电磁场（如手机产生的电磁场）、电离电磁辐射（如X射线）和非电离电磁辐射（如激光和光固化设备）会显著增加牙科汞合金修复体中汞的释放和/或导致微渗漏。
本综述结果表明，从非电离电磁场到电离辐射等多种物理应激源可显著加速汞合金中汞的释放并导致微渗漏。
