| odontogenesis | The process of development of the teeth. Synonym: odontogeny, odontosis. Origin: odonto-+ G. Genesis, production (05 Mar 2000) |

| odontogenesis imperfecta | A localised arrested tooth development which appears to involve most commonly the anterior teeth, usually on one side of the midline, most often the maxillary central and lateral incisors. Roentgenographically, the teeth have a ghostlike appearance. Calcification and bits of prismatic enamel may be found in the pulp and the enamel is thin and absent in part. (12 Dec 1998) |
| odontogenic cyst | A cyst derived from odontogenic epithelium. Origin: odont-+ G. Genos, birth, origin, + suffix -ic, pertaining to (05 Mar 2000) |
| odontogenic cyst, calcifying | A mixed radiolucent-radiopaque lesion of the jaws with features of both a cyst and a solid neoplasm. It is characterised microscopically by an epithelial lining showing a palisaded layer of columnar basal cells, presence of ghost cell keratinization, dentinoid, and calcification. (12 Dec 1998) |
| odontogenic cysts | Cysts found in the jaws and arising from epithelium involved in tooth formation. They include follicular cysts (e.g., primordial cyst, dentigerous cyst, multilocular cyst), lateral periodontal cysts, and radicular cysts. They may become keratinised (odontogenic keratocysts). Follicular cysts may give rise to ameloblastomas and, in rare cases, undergo malignant transformation. (12 Dec 1998) |
| odontogenic dysplasia | A localised arrested tooth development which appears to involve most commonly the anterior teeth, usually on one side of the midline, most often the maxillary central and lateral incisors. Roentgenographically, the teeth have a ghostlike appearance. Calcification and bits of prismatic enamel may be found in the pulp and the enamel is thin and absent in part. (12 Dec 1998) |
| odontogenic epithelial cell | Epithelial layer that will give rise to teeth. (18 Nov 1997) |
| odontogenic fibroma | <tumour> A rare odontogenic tumour found in soft tissue or as a central bony lesion. The tumour is composed of fibrous connective tissue, odontogenic epithelium, and sometimes calcification. (05 Mar 2000) |
| odontogenic keratocyst | A cyst of dental lamina origin with a high recurrence rate and well-defined histologic criteria of a corrugated parakeratin surface, uniformly thin epithelium, and a palisaded basal layer. One manifestation of the basal cell nevus syndrome. (05 Mar 2000) |
| odontogenic myxoma | <tumour> A benign, expansile, multilocular radiolucent neoplasm of the jaws consisting of myxomatous fibrous connective tissue; presumably derived from the mesenchymal components of the odontogenic apparatus. (05 Mar 2000) |
| odontogenic tumours | Neoplasms produced from tooth-forming tissues. (12 Dec 1998) |
| odontogeny | <physiology> Generetion, or mode of development, of the teeth. Origin: Odonto- + root of Gr. To be born: cf: F. Odontogenie. Source: Websters Dictionary (01 Mar 1998) |

| odontogenic cyst |
one derived from epithelium, usually containing fluid or semisolid material, which develops during various stages of odontogenesis. Nearly all odontogenic cysts are enclosed within bone. Primordial, dentigerous, periodontal, and gingival cysts are the specific types.
