Taurodontism

The term was coined by taurus meaning "bull" and the Greek ὀδούς ( odous), genitive singular ὀδόντος ( odontos) meaning "tooth", to indicate the similarity of these teeth to those of hoofed/ Radiographic characteristics of taurodontism include: • lack of pulp chamber constriction at the • an enlarged pulp chamber that appears rectangular in shape; and • displacement of the pulp chamber floor toward the root apex, shortening the roots and Earlier classification systems considered only the apical displacement of the pulp chamber floor; whereas, later systems additionally consider the position of the pulp chamber in relation to the Shaw 1928 [ ] One of the first attempts to classify taurodontism was made by C.J.Shaw. Shifman & Chanannel 1978 [ ] Later, Shifman & Chanannel Landmark ratio [ ] Landmark ratio = distance from A to B distance from B to C Where, A = the lowest point of the pulp chamber roof, B = the highest point of the pulp chamber floor, and C = the longest root’s apex. Using this formula, a tooth is a taurodont if the landmark ratio is ≥ 0.2 and the distance from the highest point of the pulp chamber floor (B) to the Classification Landmark ratio Normal < 0.2 Hypo-taurodont ≥ 0.2 - 0.209 Meso-taurodont ≥ 0.3 - 0.399 Hyper-taurodont ≥ 0.4 - 0.75 It is important to note that historically, there has been professional debate regarding thetaurodont classification systems as to: 1) how much displacement and/or morphologic change constitutes taurodontism, 2) whether cl...
