Periodontal Ligament: Health Disease and Regeneration

TIhe support and attachment of the tooth in the bones of the jaw is provided by a complex comprising four connective tissues and is known as the Periodontium. It is attached to the dentine of the root by the cementum and to the bones of the jaw via the alveolar bone.1 Two of the connective tissues are mineralized and comprise the cementum and alveolar bone while the other two are essentially fibrous in nature and are represented by the periodontal ligament (PDL) and the gingiva.
