Translations
pyorrheaenUK
pyorrhea (pīərē`ə), inflammation and degeneration of the gums and other tissues surrounding the teeth. The onset of the disease is marked by bleeding of the gums. As the disease proceeds, the gums recede from the teeth, loosening of the teeth occurs, and the bone supporting the teeth is resorbed. Pus is discharged from pockets in the gums, which are formed as the jawbone recedes from the roots of the teeth. Pyorrhea, known medically as pyorrhea alveolaris, is most common in persons over 40. There are numerous possible causes, toward which therapy is directed, including poor nutrition, poor oral hygiene, ill-fitting dentures, and irritation of the tissues by dental tartar.pyorrhea[‚pī·ə′rē·ə] (medicine) A purulent discharge. pyorrhoea (esp US), pyorrhea inflammation of the gums characterized by the discharge of pus and loosening of the teeth; periodontal disease pyorrheaenUK
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 therapy" >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.py·or·rhe·a (pī-ō-rē'ă), A purulent discharge. [pyo- + G. rhoia, a flow] pyorrhea (pī′ə-rē′ə)n.1.
