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.
Vertical root fractures represent between 2 and 5 percent of crown/root fractures. The greatest incidence occurs in endodontically treated teeth, and in patients older than 40 years of age. The occurrence of a complete vertical root fracture is often catastrophic for the individual tooth as tooth extraction is usually the only reasonable treatment.
This photo shows teeth #2-5 (Universal numbering system). Tooth #3, the upper right first molar, has an MO (mesial-occlusal) gold inlay. This molar is both posterior, as well as distal, to the premolars in front of it. Most of the principal terms can be combined using their corresponding combining forms (such as mesio-for mesial and disto-for ...

Diagram of tooth anatomy. Dental anatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dental occlusion.)
Root fracture of the tooth is a dentine cementum fracture involving the pulp. Traumatic root fracture occurs most often in the middle third of the roots of fully erupted and fully formed teeth. However, root treated teeth are more susceptible to root fracture, as this involves removing root dentine, thereby weakening the tooth.
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.
A tooth that has experienced trauma may become loose due to the periodontal ligament becoming damaged or fracture to the root of the tooth. Splinting ensures that the tooth is held in the correct position within the socket, ensuring that no further trauma occurs to enable healing. [37] A splint can either be flexible or rigid.
