Denture-related stomatitis Denture-related stomatitis Denture-related stomatitis (also termed denture sore mouth, denture stomatitis, chronic atrophic candidiasis, Candida-associated denture induced stomatitis, and denture-associated erythematous stomatitis) is a common condition where mild inflammation and redness of the oral mucous membrane occurs beneath a denture. In about 90% of cases, "Candida" species are involved, which are normally a harmless component of the oral microbiota in many people. Denture-related stomatitis is the most common form of oral candidiasis (a yeast infection of the mouth). It is more common in elderly people, and in those who wear a complete upper denture (a denture which replaces all the
Aphthous stomatitis ulcers appear at the same time, but single ulcers are possible. Healing usually takes seven to ten days and leaves no scar. Between episodes of ulceration, there is usually an ulcer-free period of variable length. This subtype makes up about 10% of all cases of aphthous stomatitis. It is termed major aphthous ulceration (MaAU) or major recurrent aphthous stomatitis (MaRAS). Major aphthous ulcers (major aphthae) are similar to minor aphthous ulcers, but are more than 10 mm in diameter and the ulceration is deeper. Because the lesions are larger, healing takes longer (about twenty to thirty days), and may leave
