Chronic periodontitis is initiated by Gram-negative tooth-associated microbial biofilms that elicit a host response, which results in bone and soft tissue destruction. In response to endotoxin derived from periodontal pathogens, several osteoclast-related mediators target the destruction of alveolar bone and supporting connective tissue such as the periodontal ligament.
The most common location of dry socket: in the socket of an extracted mandibular third molar (wisdom tooth). Since alveolar osteitis is not primarily an infection, there is not usually any pyrexia (fever) or cervical lymphadenitis (swollen glands in the neck), and only minimal edema (swelling) and erythema (redness) is present in the soft tissues surrounding the socket.
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
Healing of periapical lesions. Apical periodontitis is typically the body's defense response to the threat of microbial invasion from the root canal. [1] Primary among the members of the host defense mechanism is the polymorphonuclear leukocyte, otherwise known as the neutrophil. The task of the neutrophil is to locate and destroy microbes that ...
Periodontal disease, also known as gum disease, is a set of inflammatory conditions affecting the tissues surrounding the teeth. [5] In its early stage, called gingivitis, the gums become swollen and red and may bleed. [5] It is considered the main cause of tooth loss for adults worldwide. [7][8] In its more serious form, called periodontitis ...
Gingival recession, also known as gum recession and receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth. [ 1 ] Gum recession is a common problem in adults over the age of 40, but it may also occur starting in adolescence, or around the age ...

Pulp necrosis. Pulp necrosis is a clinical diagnostic category indicating the death of cells and tissues in the pulp chamber of a tooth with or without bacterial invasion. [1] It is often the result of many cases of dental trauma, caries and irreversible pulpitis. In the initial stage of the infection, the pulp chamber is partially necrosed for ...
