| ameloblastic odontoma | <tumour> A benign mixed odontogenic tumour comprised of an undifferentiated component histologically identical to an ameloblastoma and a well differentiated component identical to an odontoma; appears as a mixed radiolucent-radiopaque lesion and presents clinically as an ameloblastoma. Synonym: odontoameloblastoma. (05 Mar 2000) |
|---|---|
| complex odontoma | <tumour> An odontoma in which the various odontogenic tissues are organised in a haphazard arrangement with no resemblance to teeth. (05 Mar 2000) |
| compound odontoma | <tumour> An odontoma in which the odontogenic tissues are organised and resemble anomalous teeth. (05 Mar 2000) |
| odontoma | A mixed tumour of odontogenic origin, in which both the epithelial and mesenchymal cells exhibit complete differentiation, resulting in the formation of tooth structures. (12 Dec 1998) |
| coronal | A coronal plane through the body is a vertical plane from head to foot and parallel to the shoulders. (12 Dec 1998) |
| coronal epispadias | Excessively proximal position of meatus in coronal sulcus. (05 Mar 2000) |
| coronal hypospadias | Ventral and proximal malposition of meatus in the coronal sulcus. (05 Mar 2000) |
| coronal plane | A vertical plane at right angles to a sagittal plane, dividing the body into anterior and posterior portions. Synonym: frontal plane. (05 Mar 2000) |
| coronal pulp | That portion of the dental pulp contained within the pulp chamber or crown cavity of the tooth. Synonym: pulpa coronalis. (05 Mar 2000) |
| coronal section | A cross section attained by slicing, actually or through imaging techniques, the body or any part of the body or any anatomic structure in the coronal or frontal plane, i.e., in a vertical plane perpendicular to the median or sagittal plane. Since actual sectioning in the coronal plane results in an anterior and a posterior portion, an anatomical coronal section may be a two-dimensional view of the cut surface of the posterior aspect of the anterior portion, or of the anterior aspect of the posterior portion. Synonym: frontal section. (05 Mar 2000) |
| coronal suture | The line of junction of the frontal with the two parietal bones of the skull. Synonym: sutura coronalis. (05 Mar 2000) |
