To assess the working conditions of medical staff the authors compared mercury vapor concentrations released during manipulations with various copper amalgams, TMAC-01 tableted copper amalgam manufactured by Nikitiv Mercury Plant, its foreign copper analog manufactured be "Becht" (Germany), and a new CMTA capsulated copper amalgam. Use of CMTA copper amalgam was found not hazardous for medical staff provided sanitary and hygienic regulations were adhered to. Moreover, mercury vapor concentrations released during work allow its use in rooms without ventilation cabinets, whereas tableted copper amalgams TMAC-01 and Becht may be used only in dentistry rooms equipped with such cabinets.

Article Synopsis
- The study investigated urinary concentrations of 14 trace elements in 711 individuals from the Czech Republic to understand their exposure levels, including toxic metals and essential elements, and their health impacts.
- Young adults had higher levels of toxic elements, while children showed elevated levels of essential ones, with dietary factors like seafood and mushroom consumption influencing trace element concentrations.
- A significant percentage of participants exceeded the recommended health-based guidance values for arsenic and essential trace elements like zinc, indicating potential health risks associated with both deficiencies and excesses in trace element intake.*

Despite the widespread use of dental restorative materials, little information exists in the literature regarding their potential impact on bad breath. This in vitro study aims to fill this gap by investigating the influence of different restorative materials on the release of hydrogen sulfide (HS). Thirteen diverse dental restorative materials, including composites, flowable composites, glass ionomer restorative materials, high-copper amalgam, and CAD-CAM blocks, were examined.

Background: A range of different chemical interactions can generate an unexpected electronic current in a process called galvanism. Oral galvanism (OG) can also be generated by different chemical actions from diverse intraoral rehabilitated metals, including gold, copper, mercury, titanium, and titanium alloy. The main aim of this manuscript is to review OG, particularly focusing on titanium implants and related metallic materials.

Several forged 3-Polker coins have been reported in historical sources on the financial crisis that occurred between 1619 and 1623 at the start of the 30-year-long war. Supposedly, belligerent countries forged other countries' coins which were then used for external payments as a war strategy. Thus, a lot of 3-Polker coins (e.

Dental amalgam is an alloy consisting of a mixture of fine metallic powder of silver, tin, zinc, copper, and a trace amount of palladium in combination with about fifty percent elemental mercury that forms a matrix phase. Dental amalgams consisting of a high-copper content are the most common types of alloys currently utilized for the restoration of decayed, broken, and fractured posterior human teeth. The present research objective was primarily to improve the material properties by determining and analyzing the amount of mercury vapor released from dental amalgam received from eight different commercial brands.
