periodontitis

 [per″e-o-don-ti´tis]
inflammation of the periodontium, usually caused by specific pathologic bacteria that grow in the spaces between the gum and lower part of the tooth crown, and the host response to inflammation. If it continues unchecked the infection will spread to the bone in which the teeth are rooted. The bone then resorbs and the teeth slowly become detached from their supporting tissues. Periodontitis is the major cause of tooth loss after the age of 35. It can be prevented or controlled by good dental hygiene such as proper brushing and interdental cleaning, or by nonsurgical or surgical periodontal therapy. It is treated with local cleansing and débridement of the area, establishment of drainage for exudate, and use of antimicrobial agents. Antibiotic drugs and host modulating therapy are indicated if the symptoms are severe and unresponsive to other treatments. Extraction of the affected teeth may be necessary if the lesion is advanced.

per·i·o·don·ti·tis

(per'ē-ō-don-tī'tis),
1. Inflammation of the periodontium.
2. A chronic inflammatory disease of the periodontium occurring in response to bacterial plaque on the adjacent teeth; characterized by gingivitis, destruction of the alveolar bone and periodontal ligament, apical migration of the epithelial attachment resulting in the formation of periodontal pockets, and ultimately loosening and exfoliation of the teeth.
[periodontium + G. -itis, inflammation]

periodontitis

Gum disease, pyorrhea gum disease Dentistry A condition caused by progression of gingivitis, with inflammation and infection of tooth ligaments and bones supporting teeth. See Juvenile periodontitis.

per·i·o·don·ti·tis

(perē-ō-don-tītis)
1. Inflammation of the periodontium.
2. A chronic inflammatory disease of the periodontium occurring in response to bacterial plaque on the adjacent teeth; characterized by gingivitis, destruction of the alveolar bone and periodontal ligament, apical migration of the epithelial attachment resulting in the formation of periodontal pockets, and, ultimately, loosening and exfoliation of the teeth.

periodontitis

Inflammation of the PERIODONTIUM. This may be centred mainly around the root of the tooth (apical periodontitis) or may be a persistent (chronic) condition affecting the whole periodontium as a complication of severe gum inflammation (gingivitis). Treatment of apical periodontitis is by drilling to drain any pus present and filling. Chronic periodontitis requires scrupulous attention to tooth hygiene, scaling, cleaning and sometimes removal of excessive gum tissue.

Periodontitis

A gum disease that destroys the structures supporting the teeth, including bone.
