2012-03-21 · Human periodontal ligament (HPDL) is continuously exposed to mechanical stress in vivo. In this study, in utilizing DNA chips, we analyzed the influences of mechanical stress on the gene expression profile of HPDL cells in vitro.

The periodontal ligament is a structure within the gums that helps bind the teeth to the underlying alveolar bone. However, this ligament also produces cells that become bone tissue, so it’s importance in dental health is extremely significant.

It is derived from the dental follicle region, which originates from the cranial neural crest cells [1]. The ligament has an array of oriented fibres and is vascular. It is The periodontal ligament (PDL) is derived from the dental sac tissue, which invests the tooth Periodontal ligament (PDL) Definition: PDL is a connective tissue structure that surrounds the root and connects it with the bone. Structure: the periodontal ligament space has the shape of an hourglass and is narrowest at the mid root level.

These are the principal cells of the periodontal ligament. The fibroblasts they achieve remodeling Epithelial Cells. These cells in the periodontal ligament space are the remnants of Hertwig epithelial root sheath cells Undifferentiated Periodontal ligament is composed of soft complex vascular and highly cellular connective tissue that surrounds the tooth roots and connects to the inner wall of the alveolar bone (Mc Culloch CA, Lekic P, Mc Kee MD Periodontol 2000 24:56,2000) It is that soft, specialized CT situated between the cementum covering the root of the tooth and bone forming the socket wall.

Should a patient’s advanced gum disease have damaged the jawbone, placing a bone graft may be unsuccessful if the periodontal ligament is not also simultaneously restored.

A number of clinical studies have demonstrated the successful application of acellular collagen matrices in periodontal surgical reconstructions, with low patient morbidity [10– 15]. Human periodontal ligament cells (hPDLCs) play an integral part in maintaining periodontal tissue homeostasis. 20 They possess mesenchymal stem cell (MSC) character, exhibiting characteristic MSC surface markers and the ability to differentiate in vitro into various cell types including osteoblasts. 21, 22 Several studies have revealed the effects of vitamin D₃ on hPDLCs.

English Has he loosened the periodontal ligament yet? The periodontal ligament is a fibrous connective tissue between the alveolar bone proper and the cementum covering the root. This ligament covers the root of the tooth and connects with the tissue of the gingiva.

Furthermore, there was a distinct layer of cementum on the implant surface and a periodontal ligament with collagen fibers perpendicularly oriented to the implant surface, implanted into the cementum on the implant surface as well as to the opposing bone.

Many people think teeth are held in by the bone and gum tissue, but the truth is that the PDL is what really holds your teeth in place. The 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. It inserts into root cementum one side and onto alveolar bone on the other.
