Correct answer: A — Generalised erythema of the denture-bearing mucosa
Type II Newton denture stomatitis is characterised by diffuse or generalised erythema involving the mucosa covered by the denture, making A correct. Type I consists of localised pinpoint erythematous or inflamed areas, so B describes Type I. Type III is an inflammatory papillary or granular hyperplasia, usually affecting the palatal denture-bearing mucosa, so C describes Type III. Clinically normal mucosa is not denture stomatitis and therefore is not a Newton inflammatory type. Ulceration may result from denture trauma but is not one of the defining Newton categories. The term denture stomatitis is preferable to treating every case as candidiasis because its pathogenesis is multifactorial, although Candida colonisation is commonly associated.
