Owing, on the one hand, In the constant increase in the %s of nickel sensitization in the majority of allergy departments of dermatology and. on the other, to the fact that sensitization to nickel is almost always through contact with jewellery and imitation jewellery, an update was earned out on the metal alloys principally used in the manufacture of such jewellery (earrings, bracelets, necklaces, rings, winch straps, etc.) The conclusions of this review demonstrate that nickel is… 

New developments in jewellery and dental materials

This communication reviews the latest alloys introduced in the fields of jewellery and dental prostheses and it is evident that, although not always correctly used, the words “antiallergic”, “hypoallergic,” “non‐allergic" or "to avoid allergies” now appear frequently, indicating manufacturers' awareness of the problems that nickel can cause.

Palladium in dental alloys – the dermatologists’responsibility to warn?

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”.

Nickel and cobalt allergy before and after nickel regulation – evaluation of a public health intervention

Over the 20th century, the frequent use of nickel in consumer products resulted in an increasing prevalence of nickel allergy. Risk items included suspenders in the 1950s–1960s; buttons, zippers and

Palladium--a review of exposure and effects to human health.

In dental patients who are sensitive to Pd, restorations using Pd-containing materials should not be used although Pd has been used without allergic effects in some of these individuals, and those patients who have an allergy to nickel should be informed that use of PD-containing dental materials may cause Pd allergy, though this risk appears to be low.

The regulation of interventional measures related either to the manufacture and trade of adornments or professional use will better protect the population of allergy to metals.

SF-ICP-MS Analysis of Palladium in Fluids of Patients Sensitized to Metal-Based Dental Restorations

Results showed that the frequency of mono-reactions to Pd are increased from 1996 (0.11%) to 2006 (1.6%), suggesting that this metal is becoming a "new" potential allergen.

Exposure of nickel in used and unused gold‐plated earrings: a study using scanning electron microscopy and X‐ray microanalysis

Examining closely the surface of both used and unused gold‐plated earrings by scanning electron microscopy, nickel was readily detected and quantitatively determined in the scratches and pits by X‐ray microanalysis.

Metals and the skin.

It is clear that many diverse factors determine the ability of metal-based species to permeate biological membranes, not all of which have been fully defined and considerably more experimentation will be required before the specification of practically useful structure-activity relationships are possible.

Release of Palladium from Biomechanical Prostheses in Body Fluids Can Induce or Support PD-Specific IFNγ T Cell Responses and the Clinical Setting of a Palladium Hypersensitivity

The data suggest that dental appliances may represent an active source of Pd in the body, and this, in turn, can favour the clinical setting of a hypersensitivity to this metal.

Sensitization to Nickel: Etiology, Epidemiology, Immune Reactions, Prevention, and Therapy

The epidemiology, the prognosis for occupational and non-occupational nickel allergic hypersensitivity, the types of exposure and resulting immune responses, the rate of diffusion through the skin, and immunotoxicity are reviewed.
