Abstract / Excerpt:
Mercury is a well-known toxic element that is found in various forms in nature. Recently, dental amalgams have been recognized as a new source of mercury. This study was carried out under in vitro condition; the amount of mercury released from teeth restored with amalgams in the presence of Wi-Fi router radiation (non-ionizing radiation) and X-ray (ionizing radiation) using a protocol similar to Computed Tomography of Para-nasal Sinuses (CT) were analyzed separately, and in combination on the samples. For this reason, 50 human premolars were restored with a certain type of commercial amalgams. The samples were divided into five groups; control, only-CT, CT+Wi-Fi, Wi-Fi+CT and only-Wi-Fi groups, and mercury measurement were investigated at 24 and 48 hours after exposure to radiation by cold-vapor atomic absorption system. The results showed a significant difference between subgroups 24 and 48 h (p-values = 0.001 and 0.008). However, over time a significant difference was only found in CT+Wi-Fi group (p-value = 0.043). In addition, in comparison with the control group, only the subgroup that was exposed to Wi-Fi waves showed a significant difference after 24 hours (p = 0.033). In line with some of the previous studies, our findings showed that electromagnetic waves are involved in mercury release process, and warnings about the consequences of electromagnetic waves on mercury release and subtitling it with a new compound in restorative dentistry should be taken into consideration.
