Stomatitis Ulcerosa.
DEFINITION.—Inflammation of the interior of the mouth, usually unilateral, eventuating in multiple ulcerations of the mucous membrane.
SYNONYMS.—Fetid stomatitis, Phlegmonous stomatitis, Putrid sore mouth, Stomacace, are synonymous terms for idiopathic ulcerous stomatitis. Ulcero-membranous stomatitis, Mercurial stomatitis (Vogel), are synonymous terms for the deuteropathic variety of the disease.
ETIOLOGY.—The principal predisposing cause of the disease is to be found in ochlesis; the contaminating atmosphere of crowded dwellings and apartments insufficiently ventilated; uncleanliness; insufficiency of proper clothing; unhealthy food, and the like. It prevails epidemically in crowded tenements, schools, prisons, asylums, and hospitals; in garrisons and in camps; in transports and men-of-war. It is often propagated by contagion, but whether by infection or actual inoculation seems undetermined. Measles is an active predisposing cause. Feeble individuals are the most liable to the disease. It occurs at all ages. In civil life it is most frequent between the ages of four and ten years. Sometimes more girls are affected than boys (Meigs), and sometimes it is the more prevalent among boys (Squarrey). Autumn is the season of greatest prevalence.
Carious teeth, fracture and necrosis of the jaw (Meigs), and protracted catarrhal stomatitis are among the chief exciting causes. Irregular dentition is sometimes the exciting cause; and this may occur at the first and second dentition or at the period of eruption of the last molars.
PATHOLOGY.—The anatomical lesion is the destructive inflammation of portions of the mucous membrane of the mouth, leaving ulceration on detachment of the eschars. It usually commences as a gingivitis. At two periods of life—namely, from the fourth to the eighth year of life, and from the eighteenth to the twenty-fifth year—it is apt to be ulcero-membranous, a condition asserted to be altogether exceptional at other periods (Chauffard).
A diffuse fibro-purulent infiltration of the lymph-spaces of the mucosa is regarded as the first step in the pathological process. This infiltration is sufficiently abundant to compress the capillary vessels of the tissues, and thus arrest the circulation (Cornil et Ranvier). All those localized portions of mucous membrane from which the circulation is cut off perish and are discharged in fragments. The ulcers thus left are grayish, granular, and sanious, with thin, irregularly dentated borders a little undermined, through which pus can be expressed on pressure. The usual cryptogams of the oral cavity, in various stages of development, are in great abundance in the grayish detritus, which likewise contains altered red and white blood-corpuscles.
According to some observers (Caffort, Bergeron), the first evidence of the disease is an intensely congested erythematous patch, upon which one or more pustules present, point, and rupture promptly, leaving the characteristic ulcerations.
For some indeterminate reason, the ulcerations are mostly unilateral, and occur much the more frequently on the left side. The principal primal points of ulceration are upon the external borders of the gums, more frequently those of the lower jaw, and upon the corresponding surface of the cheek and lip—the cheek much oftener than the lip. Thence ulceration may extend to the tongue, less frequently to the palate. The ulcerative process follows the outline of the gums, baring the bases of the teeth to a variable extent, so that they seem elongated. On the cheek the patch of inflammation is generally oval, the longest diameter being antero-posterior, and the most frequent position is opposite to the last molar.
