Which type of acrylic resin is LEAST likely to support Candida albicans colonisation?
Show answer and explanation
Correct answer: A. Heat-cured acrylic
- A. Correct. HEAT-CURED acrylic achieves the most complete polymerisation, leaving the LOWEST residual monomer content and producing the smoothest, least porous surface. Less porosity means less surface area for candidal adhesion and biofilm retention. Residual monomer additionally irritates mucosa and may provoke a hypersensitivity reaction.
- B. Light-cured acrylic also retains more residual monomer than heat-cured material.
- C. SOFT LINERS are the WORST offenders — they are porous, they degrade and roughen over time, and they are notorious reservoirs for Candida. Soft-lined dentures require the most rigorous hygiene protocols and periodic replacement.
- D. Self-cure acrylic has significantly HIGHER residual monomer and greater porosity, favouring candidal adhesion.
