Periodontal ligaments are one of the supporting tissues of teeth that undergo remodeling during the tooth movement process. Vitamin C deficiency inhibits the regeneration of collagen fibers, which are important in tissue remodeling that affects the widening of the periodontal ligament space during the process of tooth movement. The widening of periodontal ligament space can be seen by taking radiographic photos. The purpose of this study was to determine the width of the periodontal ligament space of guinea pigs by administering vitamin C, without vitamin C, and the differences between the two

Regeneration of connective tissue attachment is the ultimate goal of periodontal therapy. It has been suggested that periodontal ligament cells possess the potential to create new connective tissue attachment. However, as cells from gingiva and alveolar bone occupy the root surface during initial wound healing, population by periodontal ligament cells is limited in vivo. We have been developing a new periodontal regeneration technique using in vitro tissue culture of periodontal ligament remaining on a periodontally involved root. The purpose of this study was to examine the periodontal healin

Growth and differentiation factors (GDF) 5, 6, and 7 are known to play roles in tendon and ligament formation, and are therefore probably involved in the formation of periodontal ligament. In this study, we sought to determine temporal and spatial expression of GDF-5, -6, and -7 mRNA in developing periodontal tissue of rat molars using in situ hybridization. GDF gene expression in the periodontal ligament was first detected in cells associated with the initial process of periodontal ligament fiber bundle formation. Gene signals were also detected in cells located along the alveolar bone and ce

The nonmineralized state of the mammalian periodontal ligament is one of the hallmarks of vertebrate evolution as it provides resilient and nontraumatic tooth anchorage for effective predation. Here we sought to determine how the chromatin state of key mineralization gene promoters contributes to the nonmineralized periodontal ligament in the midst of fully mineralized alveolar bone and cementum anchor tissues. In developing mouse periodontal tissues, RUNX2 was localized to alveolar bone–lining cells, while OSX was localized throughout the periodontal ligament’s soft tissue. Matching RT-PCR am

The periodontal ligament is a connective tissue located between the cementum that covers the roots of the tooth and alveolar bone, which is composed of large amounts of fibers, cells, and blood vessels. Orthodontic tooth movements are obtained through periodontal ligament remodeling and alveolar bone in response to orthodontic forces. When the orthodontic force is applied to the teeth, an injury will occur in the periodontal ligament, and the pressure and tension side in the periodontal ligament is formed. Furthermore, vasoconstriction occurs in blood vessels and hypoxia in the periodontal lig

Abstract In this study, we aimed to clarify the role of ascorbic acid in collagen synthesis in periodontal ligaments using osteogenic disorder Shionogi (ODS)/ShiJcl-od/od rats lacking L-gulonolactone oxidase. These rats cannot synthesize ascorbic acid in vivo. Eight-week-old ODS/ShiJcl-od/od male rats were administered ascorbic acid solution at a concentration of 200 mg/dL (control group, n = 6) or ascorbic acid solution at concentration of 0.3 mg/dL (insufficient group, n = 12). Six rats of the insufficient group were then given with ascorbic acid solution at concentration of 200 mg/dL for ad

Orthodontic treatment requires moving and aligning the teeth into a favorable position aesthetically and functionally. To achieve that, the teeth are subjected to forces to push them to their new position. Loading of force on the crown causes tipping of tooth, subsequently the periodontal ligament is compressed adjacent to the alveolar bone on the side toward which the force is directed. On the opposite side of the root, the periodontal ligament is stretched and undergoing tension. Blood vessels are compressed and blood flow is decreased on the compression side, hence less oxygen supply is rec

Orthodontic force-induced stresses cause dynamic alterations within the extracellular matrix and within the cytoskeleton of cells in the periodontal ligament and alveolar bone, mediating bone remodelling, ultimately enabling orthodontic tooth movement. In the periodontal ligament and alveolar bone, the mechanically induced tensile strains upregulate the expression of osteogenic genes resulting in bone formation, while mechanically induced compressive strains mediate predominantly catabolic tissue changes and bone resorption.

The prime objective of the periodontal treatment is to re-establish the lost periodontal tissue by forming new attachment of periodontal ligament, cementum and the alveolar bone. Periostin is a matricellular protein with its structure closely resembling to that of Drosophila fasciclin. It is expressed in the periodontal ligament, periosteum, alveolar bone, adipose tissue as well as skeletal tissue and has a key role in role in tooth development. This protein molecule has a striking similarity to the molecule beta ig-h3 which is induced by transforming growth factor beta (TGF-beta), promotes th

Signal regulatory protein alpha (SIRPα) is mainly expressed by cells of myeloid origin. This membrane glycoprotein is shown to be involved in regulation of different inflammatory conditions, such as colitis and arthritis. However, SIRPα has not been investigated in relationship to periodontitis, an inflammatory condition affecting the tooth supporting tissues. We aim to investigate if resident cells in the periodontium express SIRPα and whether a possible expression is affected by inflammatory conditions.

Directed migration of many different cell types is necessary for uneventful wound healing to occur. From clinical periodontal regeneration procedures, it is commonly believed that periodontal ligament cells will be of critical importance in obtaining a new connective tissue attachment. Here we present data which indicate that extracellular matrix components (fibronectin) and polypeptide growth factors (FGF, TGF-a, and TGF-β) modulate the ability of periodontal ligament cells to express directed migration. These data indicate a potential role for matrix components and growth factors in clinical

ABSTRACT The fibroblast integrin α11β1 is a key receptor for fibrillar collagens. To study the potential function of α11 in vivo, we generated a null allele of the α11 gene. Integrin α11−/− mice are viable and fertile but display dwarfism with increased mortality, most probably due to severely defective incisors. Mutant incisors are characterized by disorganized periodontal ligaments, whereas molar ligaments appear normal. The primary defect in the incisor ligament leads to halted tooth eruption. α11β1-defective embryonic fibroblasts displayed severe defects in vitro, characterized by (i) grea

It is known that nerve fibers containing neuropeptides such as galanin increase in the periodontal ligament during experimental tooth movement. However, the origin of galanin-containing nerve fibers in the periodontal ligament remains unclear. This study was conducted to examine our hypothesis that the increased galanin nerve fibers have a sensory neuronal origin, and that the peptide is associated with pain transmission and/or periodontal ligament remodeling during experimental tooth movement. In control rats, galanin-immunoreactive trigeminal ganglion cells were very rare and were observed p

BACKGROUND: Dental pulp stem cell (DPSC) and periodontal ligament stem cell (PDLSC) have been suggested as valuable seed cells for bone engineering, suggesting that both stem cells are potential osteogenic sources. Since DPSC and PDLSC seem like to have similar potential in bone formation, we conducted a study to compare morphology, immunophenotype and cell growth of DPSC and PDLSC isolated from the same teeth.METHODS: Human dental pulps and periodontal ligaments were obtained from freshly extracted partial impacted third molar teeth.
