Residual Monomer Induced Occupational Dermatitis from Acrylic Denture Base Resin: A Case Report

Abstract

Acrylic resins are indispensable materials in prosthodontics, primarily used for denture bases and temporary restorations. Despite their widespread use, exposure to unpolymerized monomers and degradation by-products can provoke allergic reactions among dental professionals. This case report presents a clinically documented episode of allergic contact dermatitis in a prosthodontist following repeated occupational exposure to heat-cured polymethyl methacrylate (PMMA) resin. Characteristic erythematous lesions appeared within 30 minutes of exposure, intensifying over the subsequent two hours. The report emphasizes the need for awareness, early recognition, and preventive strategies among dental professionals frequently handling acrylic-based materials.
