The term anterior teeth refers to incisors and canines, as opposed to premolars and molars, which are posterior teeth. [1] Apical The direction toward the root tip(s) or apex(es) of a tooth (the apices), as opposed to coronal, which refers to the direction toward the crown.
Apical (anatomy), an anatomical term of location for features located opposite the base of an organism or structure; Apical (chemistry), a position in certain molecular geometries in chemistry; Apical (dentistry), direction towards the root tip of a tooth; Apical consonant, a consonant produced with the tip of the tongue
In dental anatomy, the apical foramen, literally translated "small opening of the apex," is the tooth's natural opening, found at the root's very tip—that is, the root apex — whereby an artery, vein, and nerve enter the tooth and commingle with the tooth's internal soft tissue, called pulp.
The minimum crown-to-root ratio necessary is 1:1; any less support provided by the roots drastically reduces the prognosis of the tooth and its restoration. Models of human teeth as they exist within the alveolar bone. The roots, as they can be seen through the transparent "bone", exist naturally in greater inciso-apical lengths than the crowns.
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.

[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.
The lay term for dental alveoli is tooth sockets. A joint that connects the roots of the teeth and the alveolus is called a gomphosis (plural gomphoses). Alveolar bone is the bone that surrounds the roots of the teeth forming bone sockets. In mammals, tooth sockets are found in the maxilla, the premaxilla, and the mandible.
