Diagramatic representation of mucosal erosion (left), excoriation (center), and ulceration (right) Simplistic representation of the life cycle of mouth ulcers. An ulcer (/ ˈ ʌ l s ər /; from Latin ulcus, "ulcer, sore") [2] is a break in the skin or mucous membrane with loss of surface tissue and the disintegration and necrosis of epithelial tissue. [3]
(A) A small spot of decay visible on the surface of a tooth. (B) The radiograph reveals an extensive region of demineralization within the dentin (arrows). (C) A hole is discovered on the side of the tooth at the beginning of decay removal. (D) All decay removed; ready for a filling. A person experiencing caries may not be aware of the disease ...
Behçet's disease is a triad of mouth ulcers, genital ulcers and anterior uveitis. [8] The main feature of Behçet's disease is aphthous-like ulceration, but this is usually more severe than seen in aphthous stomatitis without a systemic cause, and typically resembles major or herpetiforme ulceration or both.
Green arrows indicate tooth decay. Blue arrows indicate abscess at root of tooth. The infection at the root of the tooth can travel through bone and infect surrounding soft tissue. Mouth infections are usually diagnosed on history and physical exam in the dental office or at a clinic visit with an otolaryngologist. [1]
The individual ulcers (aphthae) recur periodically and heal completely, although in the more severe forms, new ulcers may appear in other parts of the mouth before the old ones have finished healing. Aphthous stomatitis is one of the most common diseases of the oral mucosa , and is thought to affect about 20% of the general population to some ...
Along with S. sobrinus, S. mutans plays a major role in tooth decay, metabolizing sucrose to lactic acid. [2] [11] The acidic environment created in the mouth by this process is what causes the highly mineralized tooth enamel to be vulnerable to decay.
This can be caused by tooth decay, broken teeth or extensive periodontal disease (or combinations of these factors). A failed root canal treatment may also create a similar abscess. A dental abscess is a type of odontogenic infection , although commonly the latter term is applied to an infection which has spread outside the local region around ...
The pulp contains the blood vessels, the nerves, and connective tissue inside a tooth and provides the tooth's blood and nutrients. Pulpitis is mainly caused by bacterial infection which itself is a secondary development of caries (tooth decay). It manifests itself in the form of a toothache. [1]
