| electron probe | <physics> A narrow beam of electrons used to scan or illuminate an object or screen. (05 Aug 1998) |
|---|---|
| electron probe microanalyser | <apparatus> The qualitative and quantitative use of X-rays excited by a microprobe of electrons. Available with scanning electron microscope and transmission electron microscope. Acronym: EMA (05 Aug 1998) |
| electron probe microanalysis | Identification and measurement of concentration of elements based on the fact that primary-emission X-rays emitted by an element excited by an electron beam have a wavelength characteristic of that element and an intensity related to its concentration. It may be performed by an electron probe microanalyzer, an electron microscope microanalyzer, or by an electron microscope, or scanning electron microscope, fitted with an X-ray spectrometer. (12 Dec 1998) |
| apical periodontal 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) |
| Gingival-Periodontal Index | An index of gingivitis, gingival irritation, and advanced periodontal disease. (05 Mar 2000) |
| periodontal | <dentistry> Pertaining to your gums. For example periodontal disease is gum disease. (08 Jan 1998) |
| periodontal abscess | Localised circumscribed purulent area of inflammation in the periodontal tissue. It is a derivative of marginal periodontitis and commonly associated with suprabony and infrabony pockets and interradicular involvements, in contrast to periapical abscess which is attributable to pulp necrosis. (12 Dec 1998) |
| periodontal anaesthesia | Anaesthesia of the periodontal ligament, produced by injection of a local anaesthetic drug. (05 Mar 2000) |
| periodontal atrophy | Decrease in size and/or cellular elements of the periodontium after it has reached normal maturity. (05 Mar 2000) |
| periodontal attachment loss | Loss or destruction of periodontal tissue caused by periodontitis or other destructive periodontal diseases or by injury during instrumentation. Attachment refers to the periodontal ligament which attaches to the alveolar bone. It has been hypothesised that treatment of the underlying periodontal disease and the seeding of periodontal ligament cells enable the creating of new attachment. (12 Dec 1998) |
| periodontal cyst | An epithelium-lined sac containing fluid; usually found at the apex of a pulp-involved tooth. The lateral type occurs less frequently along the side of the root. (12 Dec 1998) |
| periodontal disease | <dentistry, disease> A general term that includes all diseases of the gums, teeth and underlying bone. A major cause of tooth loss. See: gingivitis and calculus. (27 Sep 1997) |
| Periodontal Disease Index | An index used for estimating the degree of periodontal disease based on the measurement of six representative teeth for gingival inflammation, pocket depth, calculus and plaque, attrition, mobility, and lack of contact. (05 Mar 2000) |
| periodontal dressings | Surgical dressings, after periodontal surgery, applied to the necks of teeth and the adjacent tissue to cover and protect the surgical wound. (boucher's clinical dental terminology, 4th ed, p218) (12 Dec 1998) |
| periodontal file | An instrument with a series of ridges or points arranged in rows on its surface, used for scaling or removing dental calculus from the teeth. (05 Mar 2000) |
