This has been generally based on the clinical appearance of the inflamed mucosa seen under maxillary complete dentures. The classification of Newton (1962) has been the most widely used. He proposed three types: (1) Pinpoint hyperaemic foci, (2) Diffuse hyperaemia of denture-supporting tissues, and (3) Papillary hyperplasia. Budtz-Jorgensen & Bertram (1970) used different terminology for the same changes: (1) Simple localized inflammation, (2) Simple diffuse (generalized) inflammation, and (3) Granular inflammation. Bergendal (1982) included only diffuse and papillary varieties and referred to atrophic or hyperplastic denture stomatitis.
