Sample item

A patient has a burning sensation and erythema of the palate only under a new acrylic denture, with a negative Candida swab. Which component is the likely allergen?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Residual methyl methacrylate monomer

Unreacted methyl methacrylate monomer in poorly cured acrylic can cause contact allergic stomatitis. A fully cured or alternative base resolves it.

Option by option

  • A. Eugenol

    Eugenol is in zinc oxide eugenol cements, not dentures.

  • B. Residual methyl methacrylate monomer (correct)

    Correct. Residual monomer is the known acrylic allergen.

  • C. Fluoride in saliva

    Salivary fluoride is not an allergen.

  • D. Polymer powder particles of titanium

    Titanium is not a component of acrylic powder.
