Occupational dermatitis due to an epoxy acrylate.
Contact Dermatitis
|February 1, 1986
Summary
A dental assistant experienced allergic reactions to dental materials containing BIS-GMA, a common monomer in composites. Patch testing confirmed BIS-GMA as the likely allergen, highlighting risks associated with dental restorative materials.
Area of Science:
- Dentistry
- Allergology
- Occupational Health
Background:
- Dental restorative materials, particularly those based on dimethacrylate monomers like BIS-GMA, are widely used in dental composites.
- Occupational exposure to dental materials can pose risks to dental professionals.
Observation:
- A dental assistant developed sensitivity to dental restorative materials shortly after commencing their use.
- The materials were identified as containing bisphenol A glycidyl methacrylate (BIS-GMA), a prevalent dimethacrylate monomer.
Findings:
- Patch testing confirmed the patient's allergic reaction to BIS-GMA, identifying it as the probable causative agent.
- High-performance liquid chromatography analysis ruled out the presence of epoxy resin in the tested materials.
- The patient also exhibited an allergy to the disinfectant Desimex i, which contains dodecyl diaminoethyl glycine.
Implications:
- This case underscores the potential for occupational allergies to common dental restorative monomers like BIS-GMA.
- Awareness and diagnostic testing are crucial for identifying allergens in dental professionals experiencing sensitivity.
- Alternative materials or protective measures may be necessary for dental workers with confirmed allergies to BIS-GMA or related compounds.
