Periodontal Wound Healing in the Absence of Periodontal Ligament Cells [PDF]
Journal of Periodontology, 1987 This experiment was designed to study the ability of mucoperiosteal flap connective tissue to form new attachment on partially demineralized roots as well as nondemineralized roots in a wound‐model where periodontal ligament (PDL) cells are absent, and ingrowth of bone granulation tissue is controlled.After reflecting mucoperiosteal flaps, bone was ...

Elastic modulus of the periodontal ligament
Biomaterials, 1997This study used a two-dimensional finite element mesh of a lower first premolar to model two different tooth loading systems which measured either the vertical or the horizontal displacements of this particular tooth. The elastic modulus of the periodontal ligament was varied in the finite element model until the horizontal and vertical displacements ...

Stresses in the periodontal ligament
Journal of Periodontal Research, 1973Measurements have been made of the root areas of forty five extracted teeth. These have been used to calculate the theoretical pressures that may occur in the region of the alveolar crest and their increase with progressive loss of alveolar bone when a lateral force is applied to the crown of the tooth.

Cementum and Periodontal Ligament Regeneration
2015The unique anatomy and composition of the periodontium make periodontal tissue healing and regeneration a complex process. Periodontal regeneration aims to recapitulate the crucial stages of wound healing associated with periodontal development in order to restore lost tissues to their original form and function and for regeneration to occur, healing ...

Canadian Journal of Biochemistry and Cell Biology, 1984
Periodontal ligament, a soft connective tissue that lies between cementum and alveolar bone in the periodontium, has been shown to contain an osteonectinlike protein. The similarity between porcine ligament osteonectin and bovine bone osteonectin was evident from immunochemical studies, from migration characteristics on sodium dodecyl sulfate ...

Pericytes in the Periodontal Ligament
2019Teeth are exposed to hundreds of oral bacteria and also challenged by the mastication forces; because teeth are situated in oral cavity, the entrance of the digestive tract, and penetrates through the oral epithelium. The periodontal ligament is a noncalcified tissue that possesses abundant blood vessels, which exist between tooth root and alveolar ...

The regenerative potential of the periodontal ligament
The Journal of Prosthetic Dentistry, 1986The current decline in the incidence of dental caries indicates that patients will retain most of their dentition. Reconstruction or regeneration of the entire attachment apparatus, including the periodontal ligament, cementum, and bone, is an attainable therapeutic goal.

Periodontal ligament injection
International Journal of Oral Surgery, 1985In an experimental double blind, cross-over study in monkeys, the reactions of the periodontal tissue after periodontal ligament injection of local anaesthetic solution were investigated. Lidocaine 20 mg/ml with adrenaline 12.5 micrograms/ml and mepivacaine 30 mg/ml were used, and the injection times were 5 or 20 s.

Unipolarity of fibroblasts in rodent periodontal ligament [PDF]
The Anatomical Record, 1979 AbstractIn order to investigate whether fibroblasts in rodent periodontal ligament have a structural polarity, the position of the Golgi apparatus or the centriolar region in the cells was studied using light and electron microscopy. It appeared that, in the periodontal ligament of continuously erupting mouse and rat incisors, centrioles in fibroblasts
