“…Akgun et al, reported that MRI cannot change the microleakage of bonded or nonbonded amalgam fillings [ 45 ]. Moreover, laser beams (Nd:YAG) with the pulse energies of 50, 150, and 250 mJ increased the mercury vapor release, that was dependent on the Nd:YAG laser pulse energy [ 30 ]. However, Pioch et al, showed that CO 2 laser, no signs of amalgam ablation or mercury vapor release were observed [ 50 ].…”

“…Several studies have reported that magnetic resonance imaging (MRI) [ 28 ], chewing and brushing in an artificial mouth [ 29 ], Nd:YAG laser pulse energy [ 30 ], radiofrequency radiation sources including Wi-Fi routers, smartphones, light-curing tools [ 31 ] and also X-rays [ 32 ] might change the rate of evaporation of mercury from amalgam fillings. Iranian scientists firstly addressed this issue in 2008 [ 33 ] but more than 10 years later, it became viral worldwide [ 34 ].…”

“…Moreover, in another study, electromagnetic radiation from Wi-Fi routers and mobile phones could increase the concentration of mercury released from amalgam restorations [ 31 ]. Furthermore, the level of mercury vapor release was significantly linked to the pulse energy of Nd:YAG laser [ 30 ]. Recently, it has been suggested that exposure of women with dental amalgam fillings to electromagnetic fields may increase the risk of autism due to higher release of mercury from dental amalgam [ 35 ].…”

How Do Different Physical Stressors’ Affect the Mercury Release from Dental Amalgam Fillings and Microleakage? A Systematic Review

et al. 2022

Background: 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. Objective: 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. Material and Methods: 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. Results: 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. Conclusion: 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.
