| periapical cemental dysplasia | <dentistry> A benign, painless, non-neoplastic condition of the jaws which occurs almost exclusively in middle-aged black females. The lesions are usually multiple, most frequently involve vital mandibular anterior teeth, surround the root apices, and are initially radiolucent (becoming more opaque as they mature). Synonym: periapical osteofibrosis. (21 Jun 2000) |

| cemental caries | <dentistry> Caries of the cementum of a tooth. (05 Mar 2000) |
|---|---|
| sclerotic cemental mass | Benign fibro-osseous jaw lesions of unknown aetiology, occurring predominantly in middle-aged black females, which present as large painless radiopaque masses usually involving several quadrants of the jaw. Synonym: florid osseous dysplasia, cemental dysplasia. (05 Mar 2000) |
| periapical | <dentistry> X-ray of individual teeth or groups of teeth. (08 Jan 1998) |
| periapical abscess | <dentistry> Acute or chronic inflammation of tissues surrounding the apical portion of a tooth, associated with the collection of pus, resulting from infection following pulp infection through a carious lesion or as a result of an injury causing pulp necrosis. (12 Dec 1998) |
| periapical curettage | <dentistry, procedure> Removal of a cyst or granuloma from its pathologic bony crypt, utilizing a curette, the removal of tooth fragments and debris from sockets at the time of extraction or of bone sequestra subsequently. (05 Mar 2000) |
| periapical cyst | An inflammatory odontogenic cyst derived histogenetically from Malassez' epithelial rests surrounding the root apex of a nonvital tooth. Synonym: periapical cyst, radicular cyst, root end cyst. (05 Mar 2000) |
| periapical diseases | Diseases of the periapical tissue. (12 Dec 1998) |
| periapical granuloma | Chronic nonsuppurative inflammation of periapical tissue resulting from irritation following pulp disease or endodontic treatment. (12 Dec 1998) |
| periapical osteofibrosis | <dentistry> A benign, painless, non-neoplastic condition of the jaws which occurs almost exclusively in middle-aged black females. The lesions are usually multiple, most frequently involve vital mandibular anterior teeth, surround the root apices, and are initially radiolucent (becoming more opaque as they mature). Synonym: periapical osteofibrosis. (21 Jun 2000) |
| periapical periodontitis | Inflammation of the periapical tissue. It includes general, unspecified, or acute nonsuppurative inflammation. Chronic nonsuppurative inflammation is periapical granuloma. Suppurative inflammation is periapical abscess. (12 Dec 1998) |
| periapical radiograph | A radiograph demonstrating tooth apices and surrounding structures in a particular intraoral area. (05 Mar 2000) |
| periapical tissue | Tissue surrounding the apex of a tooth, including the apical portion of the periodontal membrane and alveolar bone. (12 Dec 1998) |
| anhidrotic ectodermal dysplasia | A hereditary condition (most often x linked) that is characterised by the abnormal development of skin, absence of sweat glands, dry eyes and abnormal development of teeth. Symptoms include absent teeth, peg teeth, inability to sweat, thin skin and heat intolerance. Mucous membrane involvement may result in a foul-smelling nasal discharge. The inability to sweat leads to the inability to maintain normal body temperature in a warm environment. Some may exhibit fevers and will require artificial cooling. Inheritance: mostly sex-linked (X chromosome). Origin: Gr. Plassein = to form (12 Nov 1997) |
| anterofacial dysplasia | Abnormal growth of the face or cranium in an anteroposterior direction as seen and measured with a cephalogram. (05 Mar 2000) |
| arrhythmogenic right ventricular dysplasia | A congenital cardiomyopathy in which transmural infiltration of adipose tissue results in weakness and aneurysmal bulging of the infundibulum, apex, and posterior basilar region of the right ventricle and leads to ventricular tachycardia arising in the right ventricle.
