| activated resin | Autopolymerizing resin, any resin that can be polymerised by chemical catalysis rather than by the application of heat; used in dentistry for dental restoration, denture repair, and impression trays. Synonym: activated resin, cold cure resin, cold-curing resin, quick cure resin, self-curing resin. (05 Mar 2000) |
| anion exchange resin | <chemistry> A resin with fixed cationic groups which is used in chromatography to separate anionic molecules. A High molecular weight, insoluble polymers that contain functional anionic groups capable of undergoing exchange reactions. These resins are used for ion exchange chromatography, as gastric antacids, hypocholesteraemics, etc. (14 Aug 2000) |
| autopolymer resin | Autopolymerizing resin, any resin that can be polymerised by chemical catalysis rather than by the application of heat; used in dentistry for dental restoration, denture repair, and impression trays. Synonym: activated resin, cold cure resin, cold-curing resin, quick cure resin, self-curing resin. (05 Mar 2000) |

| resin | Any one of a class of yellowish brown solid inflammable substances, of vegetable origin, which are nonconductors of electricity, have a vitreous fracture, and are soluble in ether, alcohol, and essential oils, but not in water; specif, pine resin. Resins exude from trees in combination with essential oils, gums, etc, and in a liquid or semiliquid state. They are composed of carbon, hydrogen, and oxygen, and are supposed to be formed by the oxidation of the essential oils. Copal, mastic, quaiacum, and colophony or pine resin, are some of them. When mixed with gum, they form the gum resins, like asafetida and gamboge; mixed with essential oils, they frorm balsams, or oleoresins. <chemical> Highgate resin, a fossil resin resembling copal, occuring in blue clay at Highgate, near London. <botany> Resin bush, a low composite shrub (Euryops speciosissimus) of South Africa, having smooth pinnately parted leaves and abounding in resin. Origin: F. Resine, L. Resina; cf. Gr. Rhtinh. (10 Mar 1998) |
| resin acids | A class of organic compounds derived from various natural plant resins; diterpenes containing a phenanthrene ring system; e.g., abietic acid, pimaric acid, ester gums. Synonym: resinic acids. (05 Mar 2000) |
| resin cement | A monomer or monomer/polymer system used as a dental luting agent; used in cementation of restorations or orthodontic brackets to the teeth. (05 Mar 2000) |
