The direction toward the crown of a tooth, as opposed to apical, which refers to the direction toward the tip(s) of the root(s) or apex(es). It may also refer to something relating to the crown, such as coronal forces. [1]
The impact from the primary tooth will be transferred to the permanent tooth that may have its roots formed, thus causing a bend or curvature of the permanent tooth root. [5] It is noted that rather than the force of the impact, the direction in which the impact occurs has a more significant effect on dilaceration formation.
Apical (dentistry), direction towards the root tip of a tooth; Apical consonant, a consonant produced with the tip of the tongue; Apical dendrite, a type of dendrite found on pyramidal neurons; Apical dominance, the phenomenon whereby the main, central stem of a plant is dominant over other side stems
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 ...
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.
After the adult tooth forms in the bone, it will push through under the baby tooth. The adult tooth will dissolve the baby tooth's root, making the baby tooth loose until it falls out. [8] During this stage, permanent third molars (also called "wisdom teeth") are frequently extracted because of decay, pain or impactions.
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 ...
An electronic apex locator is an electronic device used in endodontics to determine the position of the apical constriction and thus determine the length of the root canal space. The apex of the root has a specific resistance to electrical current, and this is measured using a pair of electrodes typically hooked into the lip and attached to an ...
