First, the crown is removed and the pulp from the tooth cavity is extracted. The cells are then collected mechanically or enzymatically. The mechanical approach includes direct cell culture from tiny isolated pieces of the tooth pulp, whereas the enzymatic method often involves the use of dispase...
In studies of human tooth size variation (odontometrics), the measurements reported most commonly are maximum crown length (mesiodistal (MD) diameter) and maximum crown breadth (buccolingual (BL) diameter) (Kieser, 1991). In some instances, measurements are reported for crown height and intercuspa...

The core must be high enough in cervico-occlusal direction to obtain sufficient retention for the attachment of the crown. In some cases this condition cannot be fulfilled because the cervico-occlusal distances are too short resulting from extrusion of the tooth. This paper is reporting a case ...

There are some/a few short and small secondary ridges visible at the base, mainly on the oblique crown face, just above the cingulum. The cingulum is smooth, perpendicular to the tooth axis (Fig. 1b, d), and well developed both lingually and labially at about the same level. It is ...
After a lifetime of cumulative insult, crown preparation can be the final straw, bringing pulpal breakdown (Fig. 1a), and the need for root canal treatment.7 It is uncertain how many teeth lose vitality as a direct consequence of crown preparation. Bergenholtz and Nyman's8 much quoted ...
The first premolar is brachydont, with a short crown, an intervening neck, and a root of variable length. Changes in appearance of the occlusal surface of the mandibular incisors provide many cues to assist in aging a horse. View chapterExplore book Dental anatomy Padraic M. Dixon MVB, PhD...
Another dire outcome would be one where it may still be possible to salvage the 2nd molar but only after performing root canal therapy and placing a dental crown. Generally speaking, it’s one thing for a person to lose a wisdom tooth (a kind of tooth that a large percentage of people ...
