This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary. There are a few general rules about how they combine.

Cementum is a specialized bone like substance covering the root of a tooth. [15] It is approximately 45% inorganic material (mainly hydroxyapatite), 33% organic material (mainly collagen) and 22% water. Cementum is excreted by cementoblasts within the root of the tooth and is thickest at the root apex. Its coloration is yellowish and it is ...
A tooth may have multiple small accessory canals in the root apex area forming an apical delta which can complicate the endodontic problem. [1] The presence of an apical delta may make successful endodontic treatment less likely. The root tip is removed during apicoectomy to eliminate the apical delta and maximise the chance of successful ...
Taurodontism is defined as the enlargement of pulp chambers with the furcation area being displaced toward the apex of the root of a tooth. It cannot be diagnosed clinically and requires radiographic visualization since the crown of a taurodontic tooth appears normal and its distinguishing features are present below the alveolar margin.
The tooth bud (sometimes called the tooth germ) is an aggregation of cells that eventually forms a tooth and is organized into three parts: the enamel organ, the dental papilla and the dental follicle. [3] The enamel organ is composed of the outer enamel epithelium, inner enamel epithelium, stellate reticulum and stratum intermedium. [3]
Stylar shelf: A shelf or offset surface along the outer edge of the tooth. Often bears minor cusps (stylar cusps or conules). Parastyle: A forward extension of the stylar shelf which juts out at the mesiolabial (front outer) corner of the tooth, in front of and outwards from the paracone. May bear one or more minor cusps (including the ...
