Apical foramen
OPENING IN THE TIP OF THE ROOT OF A TOOTH
Apical delta; Apical foramina; Foramen apicis dentis; Foramen apicis
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's apex—whereby an artery, vein, and nerve enter the tooth and commingle with the tooth's internal soft tissue, called pulp. Additionally, the apical foramen is the point where the pulp meets the periodontal tissues, the connective tissues that surround and support the tooth.
