| Brinell hardness number | A number related to the size of the permanent impression made by a ball indenter of specified size (usually 10 mm in diameter) pressed into the surface of the material under a specified load: where P = applied load in kg, D = diameter of the ball in mm, and d = diameter of the impression in mm.

| hardness | <chemistry> Total concentration of calcium and magnesium ions, expressed as the equivalent concentration (mg/L) of calcium carbonate. Hard water is water that contains lots of calcium carbonate and other minerals. (09 Oct 1997) |
| hardness scale | A qualitative scale in which minerals are classified in order of their increasing hardness, based on the fact that the harder of two materials will scratch the softer and will not be scratched by it. The scale lists 15 substances: 1, talc; 2, gypsum; 3, calcite; 4, fluorite; 5, apatite; 6, orthoclase, periclase; 7, vitreous pure silica; 8, quartz, stellite; 9, topaz; 10, garnet; 11, tantalum carbide, fused zirconia; 12, fused alumina; 13, silicon carbide; 14, boron carbide; 15, diamond. Synonym: Mohs scale. (05 Mar 2000) |
| Knoop hardness number | A number obtained by dividing the load in kg applied to a pyramid-shaped diamond of specific size divided by the projected area of the impression: KHN = L/A, where A= the projected area of the impression in mm2 and L= the load in kg; used for measurements of hardness of any materials, especially very hard and brittle substances such as tooth dentin and enamel.

| dental restoration, temporary | A restoration placed for a limited period, from several days to sevaeral months, which is designed to seal the tooth and maintain its position until a permanent restoration (dental restoration, permanent) will replace it. (12 Dec 1998) |
| denture, partial, temporary | A partial denture intended for short-term use in a temporary or emergency situation. (12 Dec 1998) |
| temporary | Lasting for a time only; existing or continuing for a limited time; not permanent; as, the patient has obtained temporary relief. "Temporary government of the city." (Motley) Temporary star. <astronomy> See Star. Origin: L. Temporarius, fr. Tempus, temporis, time: cf. F. Temporaire. Source: Websters Dictionary (01 Mar 1998) |
| temporary base | <cell biology> A hypothetical cell adhesion molecule possibly involved in sponge cell adhesion, existence unproven. (18 Nov 1997) |
| temporary callus | The callus that develops to keep the ends of the fractured bone in apposition; it is absorbed after union is complete. Synonym: temporary callus. (05 Mar 2000) |
| temporary cartilage | A cartilage that is normally replaced by bone, to form a part of the skeleton. Synonym: ossifying cartilage, precursory cartilage. (05 Mar 2000) |
| temporary denture | A dental prosthesis to be used for a short interval of time for reasons of esthetics, mastication, occlusal support, or convenience, or to condition the patient to accept an artificial substitute for missing natural teeth until more definite prosthetic dental treatment can be provided. Synonym: provisional denture, temporary denture. (05 Mar 2000) |
| temporary memory | <psychology> Temporary storage of information for a few seconds to hours, as opposed to long-term memory which refers to material stored for days, years, or a lifetime. (12 Dec 1998) |
| temporary parasite | An organism accidentally ingested that survives briefly in the intestine. (05 Mar 2000) |
| temporary restoration | A restoration to be used for a limited period of time, in contradistinction to a permanent restoration. (05 Mar 2000) |
| temporary stricture | A stricture due to localised spasm of muscular fibres in the wall of the canal. Synonym: functional stricture, temporary stricture. (05 Mar 2000) |
| temporary hardness |
Hardness is produced by calcium and magnesium in water. These ions cause a precipitate with soap. Temporary hardness is caused by bicarbonate and can be removed by boiling which converts the bicarbonate to carbon dioxide and calcium carbonate.
