Alveolar Ulceration is distinguished from alveolar abscess by the presence of an ulcerated surface of peridental membrane instead of pus contained in a fibrous sac, the purulent matter in alveolar ulceration oozing out through the gum or around the neck of the affected tooth: no new tissue is formed, as in the case of abscess ; but the normal tissue is disorganized and wasted, and the matter discharged is watery, translucent, and may be in some cases odorless, while that from an abscess is thick, opaque and offensive. Ulceration causes little or no swelling, and the inflammation is phagedenic in character, destroying hard and soft tissues by chemical decomposition. Like alveolar abscess, it may be due to the death of the pulp, and it may begin as abscess, not being a primary disease, but always preceded by some other well-established and usually chronic affection. In alveolar ulceration a considerable portion of the peridental membrane is destroyed, and there is a wasting away of the alveolus and cementum in the region of the ulcer, whereas in alveolar abscess the peridental membrane may remain in an inflamed and morbid condition and the alveolar walls firm and penetrated at one. point to permit of the escape of the pus. In long-continued alveolar ulceration, as a result of the disease, calcareous deposits, in the form of granules, collect on the root from the ulcerated area to the margin of the gum.
The treatment consists in the thorough removal of the calcic deposit when present, and the scraping of the root of the tooth over the entire ulcerated surface, and the application of antiseptic and astringent remedies, such as listerine, aromatic sulphuric acid, etc.
