Wikipedia definition
2. Periodontal fiberThe periodontal fiber or periodontal ligament, commonly abbreviated as the PDL, is a group of specialized connective tissue fibers that essentially attach a tooth to the alveolar bone within which it sits. These fibers help the tooth withstand the naturally substantial compressive forces which occur during chewing and remain embedded in the bone. Functions of PDL are supportive, sensory, nutritive, homeostatic and eruptive.
