| afibrillar cementum | Cementum which, with the electron microscope, appears as laminated, electron-dense reticular material that sometimes overlies the enamel of the tooth. (05 Mar 2000) |
|---|---|
| cementum | <dentistry> A bony substance covering the root of a tooth. (08 Jan 1998) |
| cementum hyperplasia | A regressive change of teeth characterised by excessive development of secondary cementum on the tooth surface. It may occur on any part of the root, but the apical two-thirds are most commonly affected. (12 Dec 1998) |
| primary cementum | Cementum that has no cementocytes; may cover the entire root of the tooth, but often is missing on the apical third of the root. (05 Mar 2000) |
| secondary cementum | Cementum that forms on the root surface after eruption; it contains cementocytes. (05 Mar 2000) |
| dental cementum | <dentistry> The bonelike rigid connective tissue covering the root of a tooth from the cementoenamel junction to the apex and lining the apex of the root canal, also assisting in tooth support by serving as attachment structures for the periodontal ligament. (12 Dec 1998) |
| active caries | Microbial-induced lesions of teeth that are increasing in size. (05 Mar 2000) |
| arrested dental caries | Carious lesions that have become inactive and stopped progressing; they may exhibit changes in colour and/or consistency. (05 Mar 2000) |
| buccal caries | Caries beginning with decay on the buccal surface of a tooth. (05 Mar 2000) |
| caries | 1. <pathology> The molecular decay or death of a bone, in which it becomes softened, discoloured and porous. It produces a chronic inflammation of the periosteum and surrounding tissues and forms a cold abscess filled with a cheesy, fetid, puslike liquid, which generally burrows through the soft parts until it opens externally by a sinus or fistula. 2. <dentistry> Another name for cavities due to tooth decay, dental caries. (18 Nov 1997) |
| radiation caries | Caries of the cervical regions of the teeth, incisal edges, and cusp tips secondary to xerostomia induced by radiation therapy to the head and neck. (05 Mar 2000) |
| recurrent caries | Caries recurring in an area due to inadequate removal of the initial decay, usually beneath a restoration or new decay at a site where caries has previously occurred. (05 Mar 2000) |
| cemental caries | <dentistry> Caries of the cementum of a tooth. (05 Mar 2000) |
| mesial caries | Caries on the tooth surface that is directed toward the median plane of the dental arch. (05 Mar 2000) |
| root caries | Dental caries involving the tooth root, cementum, or cervical area of the tooth. (12 Dec 1998) |
