Interradicular Fibers

Structure and/or Key Feature(s)

There are five fiber types in the alveolodental ligament:

—alveolar crest fibers;

—apical fibers;

—horizontal fibers;

—interradicular fibers;

—oblique fibers (Rajendran and Selvam, 2015).

Anatomical Relations

Interradicular fibers are solely found in multi-rooted teeth, such as premolars and molars. These fiber bundles radiate from the interradicular septum to the furcation of the tooth (Rajendran and Selvam, 2015).

Function

Interradicular fibers, along with the other fibers of the alveolodental ligament, are responsible for anchoring the root cement to the alveolar bone (Rajendran and Selvam, 2015).
