| dentin-bonding agents | Cements that act through infiltration and polymerization within the dentinal matrix and are used for dental restoration. They can be adhesive resins themselves, adhesion-promoting monomers, or polymerization initiators that act in concert with other agents to form a dentin-bonding system. (12 Dec 1998) |
|---|---|
| dentin bridge | A deposit of reparative dentin or other calcific substances which forms across and reseals exposed tooth pulp tissue. (05 Mar 2000) |
| dentin dysplasia | An apparently hereditary disorder of dentin formation, marked by a normal appearance of coronal dentin associated with pulpal obliteration, faulty root formation, and a tendency for peripheral lesions without obvious cause. (12 Dec 1998) |
| dentin globule | Calcospherites formed by calcification or mineralization of the dentin occurring in globular areas. (05 Mar 2000) |
| dentin permeability | The property of dentin that permits passage of light, heat, cold, and chemical substances. It does not include penetration by microorganisms. (12 Dec 1998) |
| interglobular dentin | Imperfectly calcified matrix of dentin situated between the calcified globules near the dentinal periphery. (05 Mar 2000) |
| irregular dentin | Morphologically irregular dentin formed in response to an irritant. Synonym: irregular dentin, irritation dentin, reparative dentin. (05 Mar 2000) |
| opalescent dentin | Dentin usually associated with dentinogenesis imperfecta. It gives an unusual opalescent or translucent appearance to the teeth. Synonym: hereditary opalescent dentin. (05 Mar 2000) |
| tertiary dentin | Morphologically irregular dentin formed in response to an irritant. Synonym: irregular dentin, irritation dentin, reparative dentin. (05 Mar 2000) |
| eburnation of dentin | A condition observed in arrested dental caries wherein decalcified dentin is burnished and takes on a polished, often brown-stained appearance. (05 Mar 2000) |
| transparent dentin | Dentin characterised by calcification of the dentinal tubules as a result of injury or normal aging. Synonym: transparent dentin. (05 Mar 2000) |
| CS2 secondary alkylsulfohydrolase | <enzyme> From comamonas terrigena Registry number: EC 3.1.6.- Synonym: cs2 sa sulfohydrolase (26 Jun 1999) |
| protein structure, secondary | The stage in the development of protein structure in which regular hydrogen-bond interactions within contiguous stretches of polypeptide chain give rise to alpha helices and beta sheets. This is the first folding level of protein building. (12 Dec 1998) |
| secondary | Second or inferior in order of time, place or importance, derived from or consequent to a primary event or thing. Origin: L. Secundarius, secundus = second (18 Nov 1997) |
| secondary abdominal pregnancy | A condition in which the embryo or foetus continues to grow in the abdominal cavity after its expulsion from the fallopian tube or other seat of its primary development. Synonym: abdominocyesis. (05 Mar 2000) |
