Validation of an artificial tooth-periodontal ligament-bone complex for in-vitro orthodontic research
… tooth displacement may be directed in the tooth-periodontal ligament-bone-complex. In the biological environment, the periodontal ligament is the soft tissue responsible for the absorption of forces on teeth and has a direct connection to tooth mobility. Current research is limited in that it …

The Effect of Hypergravity (2g) on Osteoblast Precursor Cells in the Periodontal Ligament of the Rat
… (2g) on osteoblast histogenesis in the rat periodontal ligament (PDL), on the width of the mesial PDL, and on the percentage of forming bone surface on the mesial side of the tooth. Twenty male Wistar rats (SPF: Harlan Sprague Dawley) were randomly assigned to the centrifuge (experimental) …

Cannabinoid Receptor 2 (CB2) Ligands Downregulate Pro-Inflammatory Markers in Stimulated Primary Human Periodontal Ligament Fibroblasts (hPDLFs)
… its recreational usage and is a risk factor for periodontal disease, which is seen as a concern in society for its negative health consequences. However, many medical conditions can benefit from the pharmacological effects of cannabinoids. Plethora of evidence is available for the use of …

Orthodontic tooth movement and neurotrophins in the rat dento-alveolar complex.
… This response results in the remodelling of the periodontal ligament and the alveolar bone. When a force is placed on a tooth, the periodontal ligament is stretched and compressed depending on the direction of force. On the side where the ligament is stretched, a response resulting in bone …

Role of biological mediators in periodontal healing responses
During wound healing, cells situated in the periodontal ligament communicate with each other and induce the healing process. The periodontal ligament stem cells migrate to the inflamed site and differentiate into mesenchymal origin cells in response to chemokines. Various mediators induce the …

Mandibular anesthesia for endodontic procedures : a comparison of the mandibular block combined with a lingual supplemental injection versus the periodontal ligament injection gun delivery system
… injection as described by Schilder[1] 2. Periodontal ligament injection devices[2,3,4] 3. Gow Gates[5-9] 4. Akinosi[10] 5. Intraosseous[11] 6. Interseptal[12] This project studied the efficacy of the first two methods in delivering mandibular anesthesia for endodontic purposes. Its main …

The relationship of epithelial rests of Malassez to orthodontic resorption lacunae: a three dimensional reconstruction from serial sections
… three dimensional reconstructions of human periodontal ligament and attempts to determine the relationship of epithelial rests of Malassez with orthodontic root resorption to clarify any potential function. Root resorption was produced on the buccal surfaces of human premolars following …

Understanding periodontal diseases and diabetes through resolvins
Introduction: Periodontal diseases are a group of diseases affecting the gingival, periodontal ligament, alveolar bone, or the cementum of the oral cavity. They are highly prevalent and have been associated with many different systemic diseases such as type 2 diabetes mellitus. Resolvins are a …

Directed collisions between epithelial cells and fibroblasts in vitro on micromachined substrata
… by vacuum deposition (99). E cells from porcine periodontal ligament and F from human gingiva were cultured on grooved as well as control flat surfaces as described previously (102), and cell interactions were observed using reflected light differential interference contrast optics. Fibroblasts …

Differential expression of microRNAs in human External Cervical Root Resorption
… (ECR), periapical radiolucent lesions (PARL) and periodontal ligament (PDL) was collected from 129 teeth of 62 patients at the BU GSDM in Boston, MA. The tissue was collected from surgical and nonsurgical root canal treatment as well as extractions, and then stored in RNAlater® (Thermo Fisher …

NG2/CSPG4 Regulates Alveolar Bone and PDL Microstructure in a Sex-Dependent Manner
Periodontal disease leads to alveolar bone loss through a complex, multifactorial process involving chronic inflammation. Understanding the molecular mechanisms that regulate bone formation and resorption in alveolar tissues is essential for identifying new therapeutic targets for periodontitis. …

In vitro model of periodontal epithelium
… a model for junctional epithelium, porcine periodontal ligament epithelial cells (PLE cells) were cultured from the epithelial rests of Malassez. The obtained epithelial cell lines were grown on a porous membrane that allows a good cell adhesion and access of the nutrients from both basal …

Antimicrobial Photodynamic Therapy in Clinical Dentistry: Unravelling the Mechanisms and Exploring Hidden Benefits
… the first systematic review of PBM's effects on periodontal ligament stem cells, highlighting its potential to enhance proliferation and osteogenic differentiation for periodontal regeneration. Hence, a comprehensive understanding of the optical properties of both the photosensitizer and the …

Mechanical Evaluation of Mandibular Defects Restored with rhBMP-2: A Finite Element Model
… model included cortical bone, regenerated bone, periodontal ligament, enamel, and cementum. Boundary conditions of the subdomains were assigned using the biomechanical properties determined in the literature and the regenerated bone values were assigned based on prior testing. Finite Element …
