A patient about to begin head and neck radiotherapy receives an immediate prosthesis. What is the MOST appropriate LONG-TERM recommendation for denture care?

  1. Dry it out and store it in a sealed container
  2. Clean it with a non-abrasive denture cleanser
  3. Soak it in sodium hypochlorite solution long term
  4. Brush it with abrasive toothpaste daily
Show answer and explanation

Correct answer: B. Clean it with a non-abrasive denture cleanser

  • A. Acrylic dentures must be stored WET; drying causes dimensional change, warpage and crazing.
  • B. Correct. A NON-ABRASIVE denture cleanser preserves the surface finish, minimises biofilm retention and is safe for long-term daily use. In the irradiated, xerostomic patient this matters even more because reduced salivary flow already elevates candidal and caries risk.
  • C. Hypochlorite is useful for short soaks in specific circumstances but long-term use corrodes metal components and bleaches and weakens acrylic.
  • D. Ordinary toothpaste is abrasive to acrylic — it creates micro-scratches that harbour Candida and plaque, a particular hazard in a xerostomic irradiated patient.
