We have synthesized a new Cu amalgam, the Cu-rich phase Cu3Hg. It crystallizes with the Ni3Sn structure type with a hexagonal unit cell (space group P63/mmc , a = 5.408(4) Å, c = 4.390(3) Å) and shows some mixed occupancy of Cu on the Hg site, resulting in a refined composition of Cu3.11Hg0.89. This is the first example of an amalgam with the Ni3Sn structure type where Hg is located mainly on t...

Amalgam is a novel system for sentence realization during natural language generation. Amalgam takes as input a logical form graph, which it transforms through a series of modules involving machine-learned and knowledge-engineered sub-modules into a syntactic representation from which an output sentence is read. Amalgam constrains the search for a fluent sentence realization by following a ling...

The purpose of this study was to determine the galvanic interaction between pure titanium, a CoCrMo alloy, as well as their galvanic interaction with a high copper and a conventional amalgam at different area ratios. Pure titanium, a CoCrMo alloy and two dental amalgams with different copper compositions were tested in this study in 0.9% NaCl environment of pH 7. Polarization curves were record...

This study evaluated the shear bond strength, failure modes, and confocal microscopy of two different amalgam alloy restorations lined with five adhesive systems. Two regular-set high-copper dental amalgam alloys, Amalcap Plus and Valiant Ph.D, and five commercially available adhesive systems were selected. One hundred and twenty freshly-extracted human third molars were used for the study. The...

X-ray micro-analysis was used to determine the elemental composition of the tooth, amalgam, and base material of ten aged, amalgam-restored, posterior teeth after they had been fractured across the amalgam-tooth interface. Subsequently, replicas were used to remove marginal seal material from each interface for examination by x-ray micro-analysis. The results show that P and Sn were present in ...

INTRODUCTION Sudden fever of unknown origin is quite a common emergency and may lead to hospitalization. A rise in body temperature can be caused by infectious diseases and by other types of medical condition. This case report is of a woman who had fever at night for several days and other clinical signs which were likely related to cracked dental mercury amalgam. CASE PRESENTATION A healthy ...

93 Abstract The findings presented here suggest that mercury poisoning from dental amalgams may play a role in the etiology of oral health disorders in multiple sclerosis (MS) patients. Comparisons between MS subjects with dental amalgams and a control group of MS subjects without amalgams found significantly fewer oral cavity symptoms per subject in the amalgam-removal group during twelve mont...

This in vitro study aimed to investigate the effects of glass-ionomer and flowable composite liners on the fracture resistance of Class II amalgam and composite restorations. Group 1 cavities were restored with amalgam and Group 4 cavities with nanofill composite after the application of a dentin-bonding agent. For the remaining groups, light-cured-glass-ionomer liner was used in a gingival flo...

CONTEXT No randomized trials have been published that address the concern that inhalation of mercury vapor released by amalgam dental restorations causes adverse health effects. OBJECTIVE To compare the neuropsychological and renal function of children whose dental caries were restored using amalgam or mercury-free materials. DESIGN AND SETTING The New England Children's Amalgam Trial was a...
