ANATOMY

Detailed explanation-1: -The Periodontal Ligament (PDL) can be defined as a fibrous joint that anchors the root of the tooth to the alveolar bone socket. Made of fibrous connective tissue, it holds the tooth in sprung suspension enabling the tooth to take on the mechanical pressure during function.

Detailed explanation-2: -Support: The periodontal ligament is a component of the periodontium that allows for the teeth to be attached to the surrounding alveolar bone via the cementum. PDL fibers also transmit and absorb forces between the teeth and alveolar bone.

Detailed explanation-3: -The alveolodental ligament consists of five different fiber subgroups which include: alveolar crest, horizontal, oblique, apical and interradicular on multirooted teeth. Other principal fibers which do not include the alveolodental ligament are the transseptal fibers.

Detailed explanation-4: -Alveolar bone comprises of alveolar bone proper that lines the socket of the tooth and supporting alveolar bone. Alveolar bone proper, a layer of compact bone of 0.1–0.5 mm thickness, provides attachment to the periodontal ligament to hold the teeth firmly in the socket.

Detailed explanation-5: -The periodontal ligament is a soft connective tissue embedded between the cementum and the inner wall of the alveolar bone socket to help support teeth. The periodontal ligament harbors a small population of stem cells that are responsible for maintaining and repairing periodontal ligament tissues and function.
