|---|---|
| dental auxiliary | <specialist> Personnel whose work is prescribed and supervised by the dentist. (12 Dec 1998) |
| dental biomechanics | <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 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 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) |
