| object glass | 1. <psychology> Perceptible to the external senses. 2. <ophthalmology> The lens or system of lenses in a microscope (or telescope) that is nearest to the object under examination. Origin: L. Objectivus (18 Nov 1997) |

| object relationship | In the behavioural sciences, the emotional bond between an individual and another person (or between two groups), as opposed to the individual's (or group's) interest in him or herself (itself). (05 Mar 2000) |
| object space | <microscopy> A space within which an object could be imaged by the lens. (05 Aug 1998) |
| test object | An object having very fine surface markings, mounted on a slide, used to determine the defining power of the objective lens of a microscope, the target in measurement of the visual field. (05 Mar 2000) |
| allergic contact dermatitis | A delayed type IV allergic reaction of the skin with varying degrees of erythema, oedema, and vesiculation resulting from cutaneous contact with a specific allergen. Synonym: contact allergy. (05 Mar 2000) |
| balancing contact | The contact's between upper and lower dentures on the balancing or mediotrusive side for the purpose of stabilizing the dentures, the contact's between upper and lower dentures at the opposite side from the working or laterotrusive side (anteroposteriorly or laterally) for the purpose of stabilizing the dentures, the contact's between upper and lower natural or artificial teeth at the opposite side from the working or laterotrusive side. Synonym: balancing occlusal surface. (05 Mar 2000) |
| centric contact | The relation of opposing occlusal surfaces which provides the maximum planned contact and/or intercuspation, the occlusion of the teeth when the mandible is in centric relation to the maxillae. Synonym: centric contact. (05 Mar 2000) |
| microradiography, contact | <microscopy> A method of making micrographs by means of X-rays. The specimen is placed close to a fine-grained photographic emulsion at some distance from the X-ray source. The X rays pass through the specimen and the differential absorption and the scattering of the radiation is recorded by the emulsion. The resulting negative is examined and photographed through a light microscope. (05 Aug 1998) |
| close contact infection | <epidemiology> An infection which requires close contact, other than sexual contact, between susceptible and infectious individuals, for transmission. (05 Dec 1998) |
| contact | A mutual touching of two bodies or persons. Origin: L. Contactus = a touching together (18 Nov 1997) |

| contact area | That part of the proximal surface of a tooth which touches the adjacent tooth mesially or distally. Synonym: contact point, point of proximal contact. (05 Mar 2000) |
| contact ceptor | A nerve ceptor in the surface layer of skin or mucous membrane by means of which impulses contributed by direct physical impact are received. (05 Mar 2000) |
| contact cheilitis | Inflammation of the lips resulting from contact with a primary irritant or specific allergen, including ingredients of lipsticks. (05 Mar 2000) |
| contact dermatitis | <pathology> A type of immune-mediated inflammatory skin rash that results from an allergy to a particular substance (for example jewelry dermatitis, poison ivy, neomycin ointment, etc.). (27 Sep 1997) |
