Contact allergies to dental materials

Area of Science:

• Oral Medicine
• Dental Materials Science
• Allergology

Background:

• Epidemiological data on dental material allergies is scarce.
• Previous studies, like the German Oral Health Study (DMS V), have not adequately addressed this issue.
• Understanding the prevalence and symptoms of oral allergies is crucial for patient care.

Purpose of the Study:

• To determine the frequencies and symptoms of allergies to dental materials.
• To investigate the types of dental materials causing allergic reactions.
• To identify common oral manifestations of these allergies.

Main Methods:

• An observational study was conducted using data from a specialized consultation hour for oral mucosa allergies and material incompatibilities.
• Clinical patient data, including objective mucosal findings and subjective complaints, were systematically collected since 2012.
• 86 patients (83.7% female, mean age 63) with oral symptoms of contact allergy were included.

Main Results:

• Metal allergies, particularly to nickel and cobalt, were most prevalent.
• Allergies to cosmetic ingredients and composites were also common.
• Methacrylate-containing denture resins accounted for 5% of allergies.
• 52.4% of patients exhibited mucosal changes, with contact stomatitis (54.5%) and oral lichenoid lesions (20.5%) being most frequent.
• 86% of patients reported subjective complaints, primarily oral pain and burning sensations.

Conclusions:

• Dental material allergies, especially to metals, are a significant concern.
• Contact stomatitis and oral lichenoid lesions are common oral manifestations.
• Comprehensive dental allergy history, clinical examination, material analysis, and psychogenic disorder screening are essential for diagnosis.
