| transparent septum | A thin plate of brain tissue, containing nerve cells and numerous nerve fibres, that is stretched like a flat, vertical sheet between the column and body of fornix below, the corpus callosum above and anteriorly; it is usually fused in the median plane with its partner on the opposite side so as to form a thin, median partition between the left and right frontal horn of the lateral ventricles; in less than 10% of humans there is a blind, slitlike, fluid-filled space between the two transparent septa, the cavity of septum pellucidum. The transparent septum is continuous ventralward through the interval between the corpus callosum and the anterior commissure with the precommissural septum and subcallosal gyrus. See: cavity of septum pellucidum, septal area. Synonym: septum pellucidum, septum lucidum. (05 Mar 2000) |

| transparent ulcer of the cornea | An obsolete term for an ulcer of the cornea, occurring usually in children, that heals without opacity. (05 Mar 2000) |
| vascular dentin | Dentin in which the primitive capillaries have remained uncalcified and so are wide enough to give passage to the formed elements of the blood. Synonym: vascular dentin. (05 Mar 2000) |
| reparative dentin | Morphologically irregular dentin formed in response to an irritant. Synonym: irregular dentin, irritation dentin, reparative dentin. (05 Mar 2000) |
| peritubular dentin | An electron-dense layer of dentin observed adjacent to the odontoblastic process. (05 Mar 2000) |
| primary dentin | Dentin which forms until the root is completed. (05 Mar 2000) |
| hereditary opalescent dentin | Synonym: dentinogenesis imperfecta. Synonym: opalescent dentin. (05 Mar 2000) |
| sclerotic dentin | Dentin characterised by calcification of the dentinal tubules as a result of injury or normal aging. Synonym: transparent dentin. (05 Mar 2000) |
| secondary dentin | Dentin formed by normal pulp function after root end formation is complete. (05 Mar 2000) |
| hypersensitive dentin | Exposed dentin at the cervical portion of a tooth, painful to touch, sweetness, or temperature changes. (05 Mar 2000) |
| dentin | <dentistry> The calcified tissue below the enamel, enclosing the cavity of the tooth containing the pulp chamber and root canals. (08 Jan 1998) |
| 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) |
