BACKGROUND Dental amalgam is a source of elemental and inorganic mercury. The safety of dental amalgam in individuals remains a controversial issue. Urinary mercury concentrations are used to assess chronic exposure to elemental mercury. At present, there are no indications of mercury-associated adverse effects at levels below 5 μg Hg/g creatinine (Cr) or 7 μg Hg/L (urine). The purpose of the p...

In this study, a gold amalgam method called the "Double amalgam method" was compared with the ISO 17733 method for mercury vapor analysis method. In terms of sensitivity and ease of operation, the amalgamation method is superior to the oxidation method. Two parallel samplings were carried out in this research at a button battery factory, where the mercury vapor level in the air was about 0.001 ...

introduction : the purpose of this clinical study was to compare the blood mercury levels before and after endodontic surgery using amalgam as a root-end filling material. materials and methods: fourteen patients requiring periradicular surgery participated in this prospective clinical study. a zinc-free amalgam was employed as root-end filling material. blood samples were collected at three in...

According to the World Health Organization (WHO), factors such as growing electricity demand, ever-advancing technologies and changes in social behaviour have led to steadily increasing exposure to man-made electromagnetic fields.  Dental amalgam fillings are among the major sources of exposure to elemental mercury vapour in the general population. Although it was previously believed that low l...

Eighteen cadavers from routine autopsy casework were subject to a study of tissue levels of total mercury in brain, thyroid, and kidney samples by atomic absorption. On these same cadavers, all dental amalgam fillings (the most important source of inorganic mercury exposure in the general population, according to the World Health Organization (WHO) were charted. Total mercury levels were signif...

In their review, Esteban-Vasallo et al. (2012) discussed the use of human placenta to evaluate bio markers of exposure to heavy metals. They correctly concluded that the use of placental tissue specimens to assess heavy metal exposure is actually under used. Surprisingly, they did not mention the well-documented relationship between mercury released from mercury-containing dental amalgam fillin...

For more than a century and half, silver/mercury amalgam fillings have been used in dental practice as the preferred tooth filling material. Currently, occupational exposure of dental staff to mercury vapor released from the amalgam, has been an issue of concern because of its possible adverse outcomes. Aim: The aim of this work was to determine the mercury body burden in dental staff exposed t...

3 ilver-mercury fillings—also called dental or mercury amalgams— ave been used in dentistry since 1832. In 1840, the dental ssociation of the day argued over whether to use mercury as filling material because it was cheap, or to withdraw it ecause it was toxic. The safety debate had already begun and ould be called “Amalgam War I.” In the late 1920s, Dr Alfred tock, a biochemist and researcher,...

Studies showed that dentists and dental staff working with amalgam are chronically exposed to mercury that accumulates in their bodies in higher levels than those individuals not occupational exposed to mercury. Mercury levels in dental staff averaged at least 2 times that of control subjects in hair, nails, urine and blood. This study aimed to review long-standing mercury monitoring concentrat...
