This communication reviews the latest alloys introduced in the fields of jewellery and dental prostheses. For this we have scanned current patents and others to which we have access, and it is evident that, although not always correctly used, the words “antiallergic”, “hypoallergic”, “non‐allergic”, “to avoid allergies”, etc., now appear frequently, indicating manufacturers' awareness of the problems that nickel can cause. On the other hand, the problems that may be associated with other… 

Prosthodontic biomaterials and adverse reactions: a critical review of the clinical and research literature

A review of the clinical and research literature relating to prosthodontic biomaterials and adverse reactions shows that reliable methods seem necessary to expose the frequency of adverse reactions in general dentistry, including prosthodrontic treatment.

Diagnosis of Side Effects of Dental Materials, with Special Emphasis on Delayed and Immediate Allergic Reactions

This chapter provides numerous clinical examples of verified adverse reactions to dental materials, as well as examples of differential diagnostic considerations when handling dental patients attributing local or systemic symptoms to the presence of dental materials.

In vitro genotoxic study reinforces the use of titanium-35niobium alloy in biomedical implants

It was demonstrated that Ti-35Nb alloy did not present DNA damage and has a promising material to substitution to the materials currently used in orthopedics and in dentistry, with absence of cytotoxality and genotoxity.

Metal Allergy: Copper

Copper seems to be a weak sensitizer that should be considered in select cases, and the sources of exposure, chemistry, biology and cumulative data including case reports are reviewed to clarify the implications of copper allergy.

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.

Jewellery: alloy composition and release of nickel, cobalt and lead assessed with the EU synthetic sweat method

Several studies have shown nickel and cobalt release from jewellery by using spot tests, but the metal composition of jewellery is largely unknown.

Electrochemical comparison and biological performance of a new CoCrNbMoZr alloy with commercial CoCrMo alloy.



New trends in the use of metals in jewellery

It is demonstrated that nickel is irreplaceable in the majority of the alloys, because of its excellent technical properties and low‐ price and, as a result, the % of sensitizations to this allergen will not only maintain their present high level but will probably increase in the future.

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”.

Dental materials: 1995 literature review.

Cross-reactivity to palladium and nickel studied in the guinea pig.

In recent years there have been several reports on concomitant patch test reactions to palladium and nickel, which belong to the same group in the periodic table. Exposure to palladium mainly takes
