• periodontal ligament
  • During the last decade it has become clear that periodontal ligament fibroblasts may contribute to the in vitro differentiation of osteoclasts. (uva.nl)
  • Periodontal ligament fibroblasts have the capacity to select and attract osteoclast precursors and subsequently to retract and enable migration of osteoclast precursors to the bone surface. (uva.nl)
  • Periodontal ligament fibroblasts produce primarily OPG, an osteoclastogenesis-inhibitory molecule. (uva.nl)
  • Incubation of periodontal ligament fibroblasts with bacteria or bacterial components causes an increased expression of RANKL and other osteoclastogenesis-stimulating molecules, such as tumor necrosis factor-α and macrophage-colony stimulating factor. (uva.nl)
  • Periodontal ligament fibroblasts may be considered to play an important role in the remodelling of alveolar bone. (uva.nl)
  • In vitro experiments have demonstrated that periodontal ligament fibroblasts adapt to bacterial and mechanical stimuli by synthesizing higher levels of osteoclastogenesis-stimulating molecules. (uva.nl)
  • injury
  • This is important because Posterion cruciate ligament injury may be accompanied by a popliteal artery injury.So distal arterial pulses should be checked.If pulse is weak or ankle-brachial index is low, further evaluation should be done immediately. (explainmedicine.com)
  • causes
  • Acute PCL tear that causes significant laxity or if you have injured more than one ligament, you may need surgery to repair or reconstruct your pcl. (healthtap.com)
  • pain
  • Grade 1 & 2 sprains represent ligaments that are intact, but not functioning normally either by causing pain with use (grade 1), or pain and mild looseness or laxity (grade 2). (healthtap.com)
