Which type of ACRYLIC resin is associated with LEAST risk of denture-related candidiasis?
Show answer and explanation
Correct answer: B. Heat-cure (heat-polymerized) acrylic — LEAST Candida risk
✓ B) Heat-cure acrylic has the LEAST risk of candidiasis.
Heat-cured acrylic resins: denser, harder, less porous, less residual monomer → smoother surface → LESS Candida adherence. Chemically cured (auto-polymerized) acrylic: more porous (higher residual monomer), rougher surface → MORE Candida adherence. Key fact: 'Chemical cure is more porous and prone to candidal infections.' Denture stomatitis (most commonly Type III — inflammatory papillary hyperplasia) is caused by Candida albicans thriving in the rough surface of poorly-fitting/improperly-cleaned dentures, especially heat-cured ones with scratches from improper cleaning.
