| occlusal form | The form of the occlusal surface of a tooth or a row of teeth. Synonym: occlusal pattern. (05 Mar 2000) |
| outline form | The shape of the area of the tooth surface included within the cavosurface margins of the cavity preparation of a dental restoration. (05 Mar 2000) |
| tooth form | The characteristics of the curves, lines, angles, and contours of various teeth which permit their identification and differentiation. (05 Mar 2000) |
| equivalent form reliability | In psychology, the consistency of measurement based on the correlation between scores on two similar forms of the same test taken by the same individual. See: reliability coefficient. (05 Mar 2000) |
| twist form | See: Haworth conformational formulas of cyclic sugars. (05 Mar 2000) |
| extension form | The extension of the cavity preparation outline form to include areas of incipient carious lesions; this extension provides a dental restoration with margins that are self-cleansing or easily cleaned. (05 Mar 2000) |
| face form | The outline form of the face, the outline form of the face from an anterior view. (05 Mar 2000) |
| form | 1. <zoology> An infrasubspecific category which has no status in the classification code. 2. <suffix> In the form, shape of, mold; equivalent to -oid. See: morpho-. Origin: L. -formis, L. Forma (20 Jun 2000) |
| form perception | The sensory discrimination of a pattern shape or outline. (12 Dec 1998) |
| L form | L-forms are bacterial spheroplasts or protoplasts originating from normal bacteria following partial (spheroplasts) or complete (protoplasts) removal of the cell wall. The formation of L-forms can be either spontaneous, occuring during certain phase of growth, or artificial due to suppression of the rigid cell wall by stimuli such as enzymes, heat-shock, or special L form induction medium etc. Bacterial genera from which L-forms have been derived include: Agrobacterium, Bacillus, Bacterodes, Bartonella, Bordetella, Brucella, Clostridium, Corynebacterium, Erysipelothrix, Escherichia, Flavobacterium, Haemophilus, Listeria, Neisseria, Proteus, Pseudomonas, Salmonella, Sarcina, Serratia, Shigella, Staphylococcus, Streptobacillus, Streptococcus, and Vibrio.

| acid wave | A temporary increase in the acidity of the urine occurring during fasting. Synonym: acid wave. (05 Mar 2000) |
| alkaline wave | A period of urinary neutrality or even alkalinity after meals due to withdrawal of hydrogen ion for the purpose of secretion of the highly acid gastric juice. Synonym: alkaline wave. (05 Mar 2000) |
| alpha wave | Brain waves in the encephalogram which have a frequency of 8 to 13 per second. They are typical of the normal person awake and in a quiet resting state, and occur principally in the occipital region. (12 Dec 1998) |
| arterial wave | A wave in the jugular phlebogram due to transmission of carotid artery pulsation. B wave, the initial positive deflection in the electroretinogram, possibly arising from the inner nuclear layer of the retina. (05 Mar 2000) |
