| Definitions |
The fibrous connective tissue that surrounds the root of a tooth, separating it from and attaching it to the alveolar bone. It extends from the base of the gingival mucosa to the fundus of the bony socket, and its main function is to hold the tooth in its socket[BTO]. |

The collagen fibers, running from the cementum to the alveolar bone, that suspend a tooth in its socket; they include apical, oblique, horizontal, and alveolar crest fibers, indicating that the orientation of the fibers varies at different levels[http://www.drugs.com/dict/desmodentium.html]. The fibrous connective tissue that surrounds the root of a tooth, separating it from and attaching it to the alveolar bone. It extends from the base of the gingival mucosa to the fundus of the bony socket, and its main function is to hold the tooth in its socket[BTO]. It consist of cells, extracellular compartment of fibers. The cells are fibroblast, epithelial, undifferentiated mesenchymal cells, bone and cementum cells. The extracellular compartment consists of collagen fibers bundles embedded in ground substance. The PDL substance has been estimated to be 70% water and is thought to have a significant effect on the tooth's ability to withstand stress loads[WP][BTO:0001020, Wikipedia:Periodontal_fiber, https://github.com/obophenotype/uberon/issues/21]. |

FMA treats periodontium and periodontal ligament as the same; it has a separate class desmodentium, which we place here even though it is classified as fetal in FMA |
