| electrophoresis, gel, pulsed-field | Electrophoresis in which the direction of the electric field is changed periodically. This technique is similar to other electrophoretic methods normally used to separate double-stranded DNA molecules ranging in size up to tens of thousands of base-pairs. However, by alternating the electric field direction one is able to separate DNA molecules up to several million base-pairs in length. (12 Dec 1998) |

| electrophoresis, gel, two-dimensional | Electrophoresis in which a second perpendicular electrophoretic transport is performed on the separate components resulting from the first electrophoresis. This technique is usually performed on polyacrylamide gels. (12 Dec 1998) |
| electrophoresis, polyacrylamide gel | Electrophoresis in which a polyacrylamide gel is used as the diffusion medium. (12 Dec 1998) |
| electrophoresis, starch gel | Electrophoresis in which a starch gel (a mixture of amylose and amylopectin) is used as the diffusion medium. (12 Dec 1998) |
| two dimensional gel electrophoresis | <technique> A high resolution separation technique in which protein samples are separated by isoelectric focussing in one dimension and then laid on an SDS gel for size determined separation in the second dimension. Can resolve hundreds of components on a single gel. (18 Nov 1997) |
| acid etching, dental | Pretreatment of tooth surfaces with etching agents, usually phosphoric acid, to increase the adhesion of various resin systems. (12 Dec 1998) |
| american dental association | Professional society representing the field of dentistry. (12 Dec 1998) |
| anterior superior dental arteries | Origin, infraorbital artery within intraorbital canal; distribution, via anterior alveolar canals to upper incisors and canine teeth, mucus membrane of maxillary sinus. Synonym: arteriae alveolares superiores anteriores, anterior superior dental arteries. (05 Mar 2000) |
| apical dental foramen | The opening at the apex of the root of a tooth that gives passage to the nerve and blood vessels. Synonym: foramen apicis dentis, apical dental foramen, root foramen. (05 Mar 2000) |
| arrested dental caries | Carious lesions that have become inactive and stopped progressing; they may exhibit changes in colour and/or consistency. (05 Mar 2000) |
| biomedical and dental materials | Substances used in biomedicine or dentistry predominantly for their physical, as opposed to chemical, properties. (12 Dec 1998) |
| radiography, dental | Radiographic techniques used in dentistry. (12 Dec 1998) |
| radiography, dental, digital | A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from X-ray film or any other detector. (12 Dec 1998) |
| general practice, dental | Nonspecialised dental practice which is concerned with providing primary and continuing dental care. (12 Dec 1998) |
| partnership practice, dental | A voluntary contract between two or more dentists who may or may not share responsibility for the care of patients, with proportional sharing of profits and losses. (12 Dec 1998) |
