objectives: this study evaluated the effect of surface polishing on mercury release from dental amalgam after treatment with 16% carbamide peroxide gel. materials and methods: ninety-six samples from two different amalgam brands were prepared in truncated cone-shaped pvc polymer molds with an external surface area of 195 mm². half of the specimens were polished with green and red rubber, a brus...

INTRODUCTION Public concern about adverse health effects from mercury exposure from dental amalgams remains a high-profile issue. Patients with nonspecific neuropsychiatric symptoms may incorrectly attribute their complaints to mercury poisoning, and some alternative medical providers diagnose mercury toxicity using nonvalidated tests or without testing at all. CASE REPORT We report the case ...

While there has been considerable attention devoted to the risks to high level consumers from mercury in freshwater fish, relatively little attention has been devoted to saltwater fish. Although the U.S. Food and Drug Administration has issued advisories based on mercury for four saltwater species or groups of fish, there are few data on mercury levels generally, or on the risk these levels pos...

Mercury occurs in various chemical forms, and it is different to health effects according to chemical forms. In consideration of the point, the evaluation of the mercury exposure to human distinguished from occupational and environmental exposure. With strict to manage occupational exposure in factory, it is declined mercury intoxication cases by metallic and inorganic mercury inhalation to occ...

This study examined the relationship between mercury content and mercury evaporation from amalgams during setting. Two different types of commercial high-copper amalgams (single composition and admixed types) were used. Cylindrical specimens of each amalgam were prepared with five different mercury contents according to ADA Specification No.1. Specimens were also prepared by hand condensation. ...

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...

We contrast the interaction of mercury with adsorbed orthocarborane films and semiconducting (dehydrogenated) boron carbide. Photoemission spectra reveal small shifts in orthocarborane (C2B10H12) molecular orbital binding energies as well as the shift in mercury 5d5/2 shallow core level binding energies, suggesting only small interaction between mercury and the molecular film. Mercury does, how...

BACKGROUND With the fast growth in the market of fluorescent lamps, particularly compact fluorescent light, the associated risk of mercury exposure, which is an essential component in all types of fluorescent lamps, has received increasing public attention worldwide. Even low doses of mercury are toxic. OBJECTIVE To study the health consequences of occupational exposure to mercury in workers ...

statement of problem: amalgam is the most widely used dental restorative material. however, because of continuous low-level release of mercury from amalgam fillings, its safety has been questionable. purpose: the aim of this study was the evaluation of concentration of mercury in saliva before and after amalgam fillings and its relation with numbers and surfaces of amalgam fillings. materials a...

In this study, the mercury level in 25 commonly consumed seafood species was identified and used to evaluate the mercury intake for Taiwan population. Total mercury concentrations were determined by using furnace-gold amalgation mercury analyzer. The results indicated that mercury concentrations of the 25 seafood species ranged from 0.002 to 0.198 mg/kg wet wt. and varied significantly across s...
