Comparative Analysis of Stress in the Periodontal Ligament and Center of Rotation in the Tooth after Orthodontic Treatment Depending on Clear Aligner Thickness—Finite Element Analysis Study

open access: yesMaterials, 2021
Lately, in orthodontic treatments, the use of transparent aligners for the correction of malocclusions has become prominent owing to their intrinsic advantages such as esthetics, comfort, and minimal maintenance.

Significant type I and type III collagen production from human periodontal ligament fibroblasts in 3D peptide scaffolds without extra growth factors. [PDF]

open access: yesPLoS ONE, 2010
We here report the development of two peptide scaffolds designed for periodontal ligament fibroblasts. The scaffolds consist of one of the pure self-assembling peptide scaffolds RADA16 through direct coupling to short biologically active motifs.

ILC1s and ILC3s Exhibit Inflammatory Phenotype in Periodontal Ligament of Periodontitis Patients

open access: yesFrontiers in Immunology, 2021
Innate lymphoid cells (ILCs) are emerging as important players in inflammatory diseases. The oral mucosal barrier harbors all ILC subsets, but how these cells regulate the immune responses in periodontal ligament tissue during periodontitis remains ...

Roles of extracellular adenosine triphosphate on the functions of periodontal ligament cells

open access: yesBDJ Open, 2023
Objective Adenosine triphosphate (ATP) is an essential nucleotide that is normally present in both intracellular and extracellular compartments. Extracellular ATP (eATP) has a pivotal role in both physiological and pathological processes of periodontal ...

The role of noncoding RNAs in the osteogenic differentiation of human periodontal ligament-derived cells

open access: yesNon-coding RNA Research, 2023
Human periodontal ligament-derived cells are important seed cells for periodontal regeneration, and their osteogenic potential closely affects alveolar bone repair and periodontal regeneration.

Activity of 25-hydroxylase in human gingival fibroblasts and periodontal ligament cells. [PDF]

open access: yesPLoS ONE, 2012
We previously demonstrated that 25-hydroxyvitamin D(3) concentrations in gingival crevicular fluid are 300 times higher than those in the plasma of patients with aggressive periodontitis. Here we explored whether 25-hydroxyvitamin D(3) can be synthesized

Fibrillin-1 regulates periostin expression during maintenance of periodontal homeostasis

open access: yesJournal of Dental Sciences, 2022
Background/purpose: Human periodontal ligament consists of elastic system fibers, mainly fibrillin-1 (FBN1). Periostin (POSTN) maintains periodontal homeostasis.

Erythropoietin Activates Autophagy to Regulate Apoptosis and Angiogenesis of Periodontal Ligament Stem Cells via the Akt/ERK1/2/BAD Signaling Pathway under Inflammatory Microenvironment

open access: yesStem Cells International, 2022
Background. Angiogenic tissue engineering is a vital problem waiting to be settled for periodontal regeneration. Erythropoietin, a multieffect cytokine, has been reported as a protective factor for cell fate.

Characterization of the autocrine/paracrine function of vitamin D in human gingival fibroblasts and periodontal ligament cells. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: We previously demonstrated that 25-hydroxyvitamin D(3), the precursor of 1α,25-dihydroxyvitamin D(3), is abundant around periodontal soft tissues.

Enhancement of periodontal tissue regeneration by conditioned media from gingiva-derived or periodontal ligament-derived mesenchymal stem cells: a comparative study in rats

open access: yesStem cell research & therapeutics, 2020
Evidence has demonstrated conditioned medium (CM) from periodontal ligament stem cells (PDLSCs) improved periodontal regeneration. Gingival mesenchymal stem cells (GMSCs) have been considered an alternative strategy for regenerative medicine.
