| hard sore | The primary skin lesion of syphilis which begins at the site of infection after an interval of 10-30 days as a papule or red ulcerated skin lesion. (27 Sep 1997) |
| hard tarter | <dentistry> A calcium salt concretion which forms on your teeth. Calculus deposits form on the teeth in areas which you do not floss or brush. If these concretions are left to build up on the tooth enamel, they will irritate the gum tissue, push it away from the tooth and promote progressive bone loss. Eventually the teeth can loosen and fall out. These deposits can be removed by a dentist or a dental hygienist on an annual to biannual basis. (27 Sep 1997) |
| hard tissue | Tissue that has become mineralised, tissue having a firm intercellular substance, e.g., cartilage and bone. (05 Mar 2000) |
| hard tubercle | A tubercle lacking necrosis. (05 Mar 2000) |
| hard ulcer | <dermatology> The primary skin lesion of syphilis which begins at the site of infection after an interval of 10-30 days as a papule or red ulcerated skin lesion. (27 Sep 1997) |
| hard water | <chemistry> Hard water is water which contains minerals like calcium carbonate, magnesium carbonate, bicarbonates, sulphates, or chlorides, because it has been exposed to rocks or rocky soils. Hard water can corrode, discolour, or deposit its minerals, in and around materials such as water pipes. (09 Oct 1997) |
| ameloblastic fibroma | <tumour> A benign mixed odontogenic tumour characterised by neoplastic proliferation of both epithelial and mesenchymal components of the tooth bud without the production of dental hard tissue; presents clinically as a slow-growing painless radiolucency occurring most commonly in the mandible of children and adolescents. (05 Mar 2000) |
| aponeurotic fibroma | <tumour> A calcifying recurrent non-metastasizing but infiltrating fibroma seen most frequently on the palms of young people as a small firm nodule not attached to the overlying skin. (05 Mar 2000) |
| rabbit fibroma | A connective tissue tumour of cottontail rabbits caused by a poxvirus of the genus Leporipoxvirus and found by Shope to be transmissible with cellular suspensions or Berkefeld filtrates; it is related to myxomatosis and is used in Europe as a source of vaccine to protect against the myxoma virus. Synonym: rabbit fibroma. (05 Mar 2000) |
| rabbit fibroma virus | A poxvirus of the genus Leporipoxvirus, closely related to vaccinia and myxoma viruses, that causes Shope fibroma. Synonym: fibromatosis virus of rabbits, Shope fibroma virus. (05 Mar 2000) |
| giant cell fibroma | <tumour> A tumour of the oral mucosa composed of fibrous connective tissue with large stellate and multinucleate fibroblasts; shares a similar histology with the retrocuspid papilla, fibrous papule of the nose, pearly penile papule, and the ungual fibroma. (05 Mar 2000) |
| central cementifying fibroma | <tumour> A microscopic variant of a central ossifying fibroma. (05 Mar 2000) |
| central ossifying fibroma | <tumour> A painless, slow-growing, expansile, sharply circumscribed benign fibro-osseus tumour of the jaws that is derived from cells of the periodontal ligament; presents initially as a radiolucency that becomes progressively more opaque as it matures. See: central cementifying fibroma. (05 Mar 2000) |
| peripheral ossifying fibroma | A reactive focal gingival overgrowth derived histogenetically from cells of the periodontal ligament and usually developing in response to local irritants (plaque and calculus) on associated teeth; consists microscopically of a hyperplastic cellular fibrous stroma supporting deposits of bone, cementum, or dystrophic calcification.
