Nickel is the most common contact allergen affecting females in Europe and the USA. include all articles that appeared in each of the da-tabases, dating from the inceptions of the databases until August, 2010. For example, Ni-based alloys are widely used in costume jewelry and dental materials, and Ni frequently causes contact allergy categorized as type IV delayed-type hypersensitivity (DTH), with skin inflammation mediated by hapten-specific T cells (1–5). The MeSH term used was allergy and orthodontics. A total of 106 articles were retrieved in nickel allergy and orthodontics. Dent Mater 2014: 30: 1325-1335. The search revealed a total of 114 articles on the topic. If you originally registered with a username please use that to sign in. Nickel results in one of the most common metal-induced allergic contact dermatitis in humans; it produces more allergic reactions than all the other metals combined together. 12 Noble J, Ahing S I, Karaiskos N E, Wiltshire W A. Nickel allergy and orthodontics, a review and report of two cases. You do not currently have access to this article. The following keywords were used in the search: “nickel-free”, associated to “or-thodontics”, “orthodontic brackets”, “nickel allergy and orthodontics”, “allergy”, “orthodontic appli- The aim of this study was to elucidate whether nickel sensitive persons are at greater risk of developing discomfort in the oral cavity during orthodontic treatment. Nickel is the most common component of the super-elastic nickel-titanium (Ni-Ti) archwires used during the initial levelling and aligning phase of orthodontic treatment with a concentration of 47-50%. Orthodontics. The findings do not indicate that nickel sensitive persons are at greater risk of developing discomfort in the oral cavity when wearing an intraoral orthodontic appliance. Don't already have an Oxford Academic account? Nickel titanium wires are often used for orthodontics. INTRODUCTION ˚ Allergic response to alloys in orthodontics, particularly nickel, has been extensively studied and several case reports of nickel-induced contact dermatitis have been documented. This article is also available for rental through DeepDyve. Stainless steel orthodontic components are therefore very unlikely to cause nickel hypersensitivity. This consideration receives even greater attention with the expanded use of nickel titanium alloys, which contain up to 70% nickel. [6-9] Nickel hypersensitivity is more prevalent in females than in males by a factor of 10 to 1. This study aimed to systematically review the effect of fixed orthodontic treatment on salivary levels of these ions by doing a meta-analysis on cross-sectional and cohort studies.

It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. The search revealed a total of 114 articles on the topic. Stainless steel orthodontic components are therefore very unlikely to cause nickel hypersensitivity. Despite gingival inflammation being considered an allergic reaction to metals in orthodontic appliances, 23 the onset of periodontal disease depends mainly on the accumulation of biofilm. Nickel is one of the most common causes of allergic contact dermatitis and produces more allergic reactions than all other metals combined. Settleable matter in a highly industrialized area: Chemistry and health risk assessment. A nickel allergy occurs when a person has an adverse reaction to a food or object containing nickel. A total of 106 articles were retrieved in nickel allergy and orthodontics. No nickel allergic reaction on the oral mucosa was found. described. But nickel can be found in many everyday items, such as coins, zippers, cellphones and eyeglass frames.It may take repeated or prolonged exposure to items containing nickel to develop a nickel allergy. The five female patients sensitive to nickel were followed monthly by intraoral photos and gingival and plaque index scores. What is nickel allergy?. The remaining patients began routine orthodontic therapy and were retested 3 months into treatment to see whether sensitization occurred. Register, Oxford University Press is a department of the University of Oxford. You could not be signed in. Most studies have concluded that patients with a nickel allergy are able to wear appliances with stainless steel elements without a noticeable effect. A search was conducted on PubMed to retrieve all available literature on allergy and orthodontics. Men in metal processing and manufacturing occupations are also likely to develop a nickel contact allergy. History of environmental contamination at Sunny Corner Ag-Pb-Zn mine, eastern Australia: A meta-analysis approach. Nickel ion release is higher when a cell phone is used a lot. Nickel is widely used in orthodontics.22 However, few studies address the influence of this metal on periodontal health, especially in a longitudinal fashion. It is possible to i nfer that inflammatory lesions are frequent manifestations on the use of nickel in orthodontic patients. Copyright © 2021 European Orthodontic Society. Spring hard stainless steel (EN-standard Steel no: 1.4310) used in orthodontics contains up to 9% nickel (Figure 3). Introduction. Don't already have an Oxford Academic account? Nickel-containing metal alloys are extensively used for dental prostheses and orthodontic appliances. Nickel is one of the most common causes of allergic contact dermatitis and produces more allergic reactions than all other metals combined. Nickel-containing metal alloys are extensively used for dental prostheses and orthodontic appliances. Allergic response to alloys in orthodontics, particularly nickel, has been extensively studied and several case reports of nickel-induced contact dermatitis have been documented. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Nickel allergy, also known as nickel hypersensitivity or Systemic Nickel Allergy Syndrome (SNAS), results from an adverse immune response to nickel exposure.

Nickel sensitivity patch tests were conducted to confirm hypersensitivity to nickel. Allergic response to alloys in orthodontics, particularly nickel, has been extensively studied and several case reports of nickel-induced contact dermatitis have been documented. There may be a risk of sensitizing patients to nickel with long-term exposure to nickel-containing applicances as occurs in routine orthodontic therapy. The study aimed to evaluate to which extent self-reported symptomatology, age, and sex are predictors of titanium and nickel allergic sensitization in patients in treatment with fixed orthodontic appliances. Nickel hypersensitivity is a common problem, especially among young females, with a prevalence of 5 to 10%, increasing to 30%. Nickel stands out as the main cause of contact allergy in both children and adults, which has given rise to concern and the introduction of regulations by official bodies. Currently, several brands of orthodontic wires are made of nickel titanium alloy and potentially have a high enough nickel content to provoke manifestations of allergic reactions in the oral cavity.
