Which microorganism MOST commonly causes denture-related stomatitis?

Candida albicans is the primary etiologic agent of denture stomatitis (chronic atrophic oral candidiasis). The denture acts as a reservoir for Candida biofilm, causing erythema under the denture-bearing area. It's the most common oral fungal infection. Treatment: antifungal medication + denture disinfection + proper denture hygiene.
