Dental Soldering
|
D012994 |
[The joining of pieces of metal through the use of an alloy which has a lower melting point, usually at least 100 degrees Celsius below the fusion temperature of the parts being soldered. In dentistry, soldering is used for joining components of a dental appliance, as in assembling a bridge, joining metals to orthodontic bands, or adding to the bulk of certain structures, such as the establishment of proper contact areas on inlays and crowns with adjacent teeth. (Illustrated Dictionary of Dentistry, 1982)

Dental Stress Analysis
|
D003799 |
[The description and measurement of the various factors that produce physical stress upon dental restorations, prostheses, or appliances, materials associated with them, or the natural oral structures.

Dental Veneers
|
D003801 |
[The use of a layer of tooth-colored material, usually porcelain or acrylic resin, applied to the surface of natural teeth, crowns, or pontics by fusion, cementation, or mechanical retention.

Dentate Gyrus
|
D018891 |
[A subsection of the hippocampal formation, described by Lorente de No, that composes the hilus of the DENTATE GYRUS.
, GRAY MATTER situated above the GYRUS HIPPOCAMPI. It is composed of three layers. The molecular layer is continuous with the HIPPOCAMPUS in the hippocampal fissure. The granular layer consists of closely arranged spherical or oval neurons, called GRANULE CELLS, whose AXONS pass through the polymorphic layer ending on the DENDRITES of PYRAMIDAL CELLS in the hippocampus.

Dentifrices
|
D003802 |
[Any preparations used for cleansing teeth; they usually contain an abrasive, detergent, binder and flavoring agent and may exist in the form of liquid, paste or powder; may also contain medicaments and caries preventives.

|
Dentigerous Cyst
|
D003803 |
[Most common follicular odontogenic cyst. Occurs in relation to a partially erupted or unerupted tooth with at least the crown of the tooth to which the cyst is attached protruding into the cystic cavity. May give rise to an ameloblastoma and, in rare instances, undergo malignant transformation.

|
Dentin
|
D003804 |
[The hard portion of the tooth surrounding the pulp, covered by enamel on the crown and cementum on the root, which is harder and denser than bone but softer than enamel, and is thus readily abraded when left unprotected. (From Jablonski, Dictionary of Dentistry, 1992)

|
Dentin Desensitizing Agents
|
D057133 |
[Substances which reduce or eliminate dentinal sensitivity or the pain associated with a source of stimulus (such as touch, heat, or cold) at the orifice of exposed dentinal tubules causing the movement of tubular fluid that in turn stimulates tooth nerve receptors.
] |
|
Dentin Dysplasia
|
D003805 |
[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. (From Dorland, 27th ed)

|
Dentin Permeability
|
D003806 |
[The property of dentin that permits passage of light, heat, cold, and chemical substances. It does not include penetration by microorganisms.

|
Dentin Sensitivity
|
D003807 |
[Pain associated with exposed DENTIN surfaces of the teeth.

Dentin Solubility
|
D003808 |
[The susceptibility of the DENTIN to dissolution.

|
Dentin, Secondary
|
D003809 |
[Dentin formed by normal pulp after completion of root end formation.
] |
|
Dentin-Bonding Agents
|
D017220 |
[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.
] |
|
Dentinal Fluid
|
D019234 |
[The lymph or fluid of dentin. It is a transudate of extracellular fluid, mainly cytoplasm of odontoblastic processes, from the dental pulp via the dentinal tubules. It is also called dental lymph. (From Stedman, 26th ed, p665)
] |
|
Dentinogenesis
|
D003810 |
[The formation of dentin. Dentin first appears in the layer between the ameloblasts and odontoblasts and becomes calcified immediately. Formation progresses from the tip of the papilla over its slope to form a calcified cap becoming thicker by the apposition of new layers pulpward. A layer of uncalcified dentin intervenes between the calcified tissue and the odontoblast and its processes. (From Jablonski, Dictionary of Dentistry, 1992)
