Objective: Different techniques have been suggested for the repair of bone defects at the injured sites. Use of biomembranes, or application of plasma rich in growth factor (PRGF) at the site of proliferation of osteoblasts are among the suggested techniques. The current study aimed to compare the biocompatibility of human periodontal ligament fibroblasts (hPLF) cultured on Hypro-Sorb F, Peri...
Periodontium is a complex organ composed of mineralized epithelial and connective tissue. Dexamethasone could stimulate proliferation of osteoblast and fibroblasts. This study aimed to assess the osteogenic effect of dexamethasone on periodental ligament (PDL) stem cells. PDL stem cells were collected from periodontal ligament tissue of root of extracted premolar of young and healthy people. Th...
Periodontitis is an inflammatory disease leading to the destruction of periodontal tissue. Vitamin D3 is an important hormone involved in the preservation of serum calcium and phosphate levels, regulation of bone metabolism and inflammatory response. Recent studies suggest that vitamin D3 metabolism might play a role in the progression of periodontitis. The aim of the present study was to exami...
Regeneration of mineralized tissues affected by chronic diseases comprises a major scientific and clinical challenge. Periodontitis, one such prevalent disease, involves destruction of the tooth-supporting tissues, alveolar bone, periodontal-ligament and cementum, often leading to tooth loss. In 1997, it became clear that, in addition to their function in enamel formation, the hydrophobic ectod...
avulsion is one of the most serious emergencies in dental office. in the event of any problem, the tooth should be stored in a medium that supports the periodontal ligament cell viability. in other clinical situations, preserving media, growth factors and mitogenic products may be useful in repairing the traumatized tissues. it has been previously reported that levodopa (l-dopa) accelerates hea...
Manipulation of stem cells or stem cells-derived secretome has emerged as a novel alternative therapeutic option for multiple sclerosis (MS). Here we show that human periodontal ligament stem cells (hPDLSCs)-derived conditioned medium (hPDLSCs-CM) and purified exosomes/microvesicles (hPDLSCs-EMVs) obtained from Relapsing Remitting (RR)-MS patients and healthy donors block experimental autoimmun...
Histological Evaluation of Periodontal Ligament in Response to Orthodontic Mechanical Stress in Mice
The purpose of the study was to determine the cell dynamics in periodontal ligament in response to mechanical stress during orthodontic movement. Following Waldo's method, a square sheet of rubber dam was inserted in between the first and second maxillary molars in 10 ddY mice leaving the stress load for 3 hours. After 3 days and at 1 week, cell count on pressure and tension sides of the period...
