DISEASES OF THE MOUTH
The mouth, in which the preliminary process of digestion begins, has a number of functions to perform. A disturbance of any of these functions indicates the presence of disease in the mouth or at some distance, as in the stomach, and bowels. In the mouth the starchy portions of the diet are given their first digestion. The absence of a number of teeth or the presence of bad teeth may disturb the preparation of food affecting the process of digestion in the mouth as well as in the stomach.
One of the commonest mouth diseases is periodontitis. This disease occurs usually during middle or late life. In some cases it may result from infection due to lowered resistance within the teeth and gums. The teeth may loosen and separate, the gums becoming inflamed. Stomatitis refers to a condition characterized by inflammation of the oral cavity.
Stomatitis is an inflammation of the soft tissues of the mouth occurring as a result of mechanical, chemical, thermal, bacterial, viral, electrical, or radiation injury or reactions to allergens or as secondary manifestations of systemic disease. There are various types of this disease such as catarrhal stomatitis, chronic stomatitis, simple stomatitis, chemical stomatitis and so on. In stomatitis infection and inflammation of the mucous membrane of the oral cavity may involve the gingiva, the palate, the tongue, the cheeks and the lips.
The lesion may be of local origin or it may be a symptomatic expression of general disease.
Simple Stomatitis. The mucous membrane of the oral cavity being inflamed, it becomes sensitive and red. Often the tongue and pharynx are involved. The temperature may rise very high, especially in children.
Mastication is often interfered, the breath being fetid. It may be due to catarrh of the upper air passages or digestive disturbances.
