The BEST method to cure denture acrylic to help prevent Candida colonization and growth is:

Correct answer: A. Injection molding with heat-cure resin (autoclave/pressure-pot curing)

• A. Correct. Heat-cured (injection-molded) resin produces a denser, smoother, more cross-linked acrylic surface with fewer microporosities compared to cold-cure resin. Candida albicans colonizes the pores and scratches of denture surfaces — a smoother, denser surface from heat-cure reduces adhesion and colonization.
• B. Cold-cure (autopolymerizing) acrylic is more porous and contains more residual monomer — creating a rougher surface that is MORE prone to Candida colonization, not less.
• C. Light-cure resins are used for specific clinical applications but not typically for full denture fabrication.
• D. Microwave curing can produce acceptable density but is not the specifically identified optimal method for preventing Candida.
