Drug hypersensitivity to dental materials (review)

Relevance. The increasing prevalence of hypersensitivity reactions to dental materials among the population of any age entails the need to understand the diversity of the etiology of this problem in order to prevent allergic manifestations in dental practice. Materials and methods. Scientific papers were searched in the search engines PubMed, ScienceDirect, Wiley Online Library, SpringerLink, RusMed, eLibrary.ru by keywords: allergy to dental materials, allergy to metals, hypersensitivity to polymers, allergy to acrylates, allergy to latex. The search depth was 5 years (2020–2025). The source search algorithm followed the principles of PRISMA. 516 foreign and domestic publications were identified. A total of 41 publications from an electronic search in the above databases and 19 articles additionally found using a manual search were included in the analysis. Results. Among dental materials, metals and polymers are the most common chemical components that can cause hypersensitivity reactions. Hypersensitivity reactions can manifest as immediate hypersensitivity reactions (type I) to metals, latex and some polymers with clinical manifestations in the form of urticaria, angioedema, bronchospasm and anaphylaxis, or delayed hypersensitivity reactions, more often to metals with symptoms of contact allergic dermatitis. Dental materials with biocompatibility issues include composites, latex gloves, local anesthetics, endodontic materials, casts, and metals. The most common manifestations of allergies in dental patients are cheilitis and perioral dermatitis (25.6 %), burning mouth syndrome (15.7 %), lichenoid reaction (14 %) and orofacial granulomatosis (10.7 %). Common contact allergens were sodium thio-sulfate (14 %), nickel sulfate (13.2 %), mercury (9.9 %), palladium chloride (7.4 %), and 2-hydroxyethylmethacrylate (5.8 %). While dental clinic staff usually have contact dermatitis of the hands. The most common causes of contact allergic dermatitis in dental workers are metals, latex, antimicrobials, formaldehyde, preservatives, and methacrylates. Conclusion. To clarify the diagnosis, it is important to find out a detailed allergy-related medical history, clinical examination, and confirmatory tests such as patch tests and MELISA. The latest ELISA research method should be widely implemented in real practice.
