| dental biophysics | <dentistry> The relationship between the biologic behaviour of oral structures and the physical influence of a dental restoration. Synonym: dental biomechanics. (05 Mar 2000) |
|---|---|
| dental branches | <anatomy, dentistry> Branches to the teeth. Nomina Anatomica lists dental branches of the following: 1) anterior superior alveolar artery, rami dentales arteriarum alveolarium superiorum anteriorum; 2) inferior alveolar artery, rami dentales arteriae alveolaris inferioris; 3) inferior dental plexus, rami dentales inferiores plexus dentalis inferioris; 4) posterior superior alveolar artery, rami dentales arteriae alveolaris superioris posterioris; 5) superior dental plexus, rami dentales superiores plexus dentalis superioris. Synonym: rami dentales, dental rami. (05 Mar 2000) |
| dental bulb | <dentistry> The papilla, derived from mesoderm, that forms the part of the primordium of a tooth that is situated within the cup-shaped enamel organ. (05 Mar 2000) |
| dental calculus | <dentistry> Hard, stonelike concretion, varying in colour from creamy yellow to black, that forms on the teeth or dental prostheses through calcification of dental plaque. (12 Dec 1998) |
| dental canals | Canals in the body of the maxilla that transmit nerves and vessels from the alveolar foramina to the maxillary teeth. Synonym: canales alveolares, alveolodental canals, dental canals. (05 Mar 2000) |
| dental caps | <veterinary> Deciduous cheek teeth in the horse which remain attached to erupting permanent teeth. (05 Mar 2000) |
| dental caries | <dentistry> Erosion and decay of the tooth caused by the effects of bacteria in the mouth. (27 Sep 1997) |
| dental cast | <dentistry> A positive likeness of a part or parts of the oral cavity. (05 Mar 2000) |
| dental casting investment | <dentistry> Material from which the casting mold is made in the fabrication of gold or cobalt-chromium castings. (boucher's clinical dental terminology, 4th ed, p168) (12 Dec 1998) |
| dental casting technique | <dentistry> The process of producing a form or impression made of metal or plaster using a mold. (12 Dec 1998) |
| dental cavity lining | <dentistry> An inner coating, as of varnish or other protective substance, to cover the dental cavity wall. It is usually a resinous film-forming agent dissolved in a volatile solvent, or a suspension of calcium hydroxide in a solution of a synthetic resin. The lining seals the dentinal tubules and protects the pulp before a restoration is inserted. (12 Dec 1998) |
| dental cavity preparation | <dentistry> An operation in which carious material is removed from teeth and biomechanically correct forms are established in the teeth to receive and retain restorations. A constant requirement is provision for prevention of failure of the restoration through recurrence of decay or inadequate resistance to applied stresses. (boucher's clinical dental terminology, 4th ed, p239-40) (12 Dec 1998) |
| dental cement | <dentistry> Bonding substances available in the form of two components that are mixed together immediately before use, setting to a hard mass. They are used in restorative and orthodontic dental procedures as luting (cementing) agents, as bases, and as restorative materials. Resins and polymers used as restorative materials are usually called restorative resins rather than cements. (12 Dec 1998) |
| 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) |
| dental clasps | <dentistry> Metal devices for fastening together two or more parts of dental prostheses for stabilizing or retaining them by attachment to abutment teeth. For a precision attachment for a partial denture denture precision attachment is available. (12 Dec 1998) |
