In the biomedical field, palladium has primarily been used as a component of alloys for dental prostheses. However, recent research has shown the utility of palladium alloys for devices such as vascular stents that do not distort magnetic resonance images. Dental palladium alloys may contain minor or major percentages of palladium. As a minor constituent, palladium hardens, strengthens and increases the melting range of alloys. Alloys that contain palladium as the major component also contain… Expand
Nickel alloys in the oral environment
TLDR
Current evidence suggests that nickel alloys may be used successfully and safely in dentistry if clinical risks are taken into account, however, these alloys might cause significant clinical problems, primarily allergenic and inflammatory, if the risks are ignored. Expand
Corrosion process development of a Ni-Cr-Mo alloy used in dental prosthesis
The 59.6% Ni, 24.0% Cr and 9.8% Mo alloy, used in dental prosthesis was recast in open fire oxyGLP torch and naturally cooled. The electrochemical study has shown that the alloy has behavior similarExpand

Mechanical properties, corrosion behavior and in-vitro bioactivity of nanostructured Pd/PdO coating on Ti–6Al–7Nb implant
Abstract A balanced combination of mechanical properties together with a high corrosion protection are the essential requirements for a successful joint arthroplasty. In an attempt to improve theExpand
Аллергия на металлы
TLDR
The aim of this work was to summarise scientific data on allergic reactions to metals and their diagnosis in humans and elaboration of a domestic diagnostic test for timely detection of allergies to metals is still relevant. Expand
Electroless Palladium-Coated Polymer Scaffolds for Electrical Stimulation of Osteoblast-Like Saos-2 Cells
TLDR
The results suggest that palladium-coated polyurethane foams may be good candidates for osteoblast scaffolds and demonstrate that ES enhances osteooblast proliferation up to 14 days and upregulate expression genes related to extracellular matrix formation. Expand

Biological effects of palladium and risk of using palladium in dental casting alloys.
TLDR
In spite of the potential adverse biological effects of Palladium ions, the risk of using palladium in dental casting alloys appears to be extremely low because of the low dissolution rate of palladium ions from these alloys. Expand
The mechanism of corrosion of palladium-silver binary alloys in artificial saliva.
TLDR
Examination of binary silver-palladium alloys has made possible determination of the role of the components of the alloys and model saliva in the corrosion behaviour, applicable to the more complex commercial dental alloys containing silver and palladium as major components. Expand
Corrosion resistance of cobalt-chromium and palladium-silver alloys used in fixed prosthetic restorations.
TLDR
Although the corrosion potential of the cobalt-chromium (Co-Cr) alloy was lower than that of the Pd-based alloys, the corrosion currents and polarization resistance values were similar for all three alloys. Expand

TLDR
Very contradictory data have been documented regarding the local and systemic effects of dental casting alloys and metallic ions released from them, and it is of critical importance to elucidate the release of cations from metallic dental restorations in the oral environment and to determine the biological interactions of released metal components with oral and systemic tissues.

Palladium in dental alloys – the dermatologists’responsibility to warn?
TLDR
In Austria, where palladium has started to displace amalgam in dental fillings because of concerns about mercury toxicity, and gold due to price factors, a sensitization rate of 8.3% in unselected eczema patíents is found, which should motivate us to question this substance as “the alloy of the future”.

TLDR
The results show that selective dissolution of the less-noble components occurred on the surfaces of both alloys for all the exposures, leaving the surfaces highly enriched in Pd, in spite of its higher nobility. Expand
