It was assessed by irregular junction between periodontal ligament
and bone margin and recorded as present or absent.
Stress distribution in the periodontal ligament
of anterior teeth.
A minimal handling and an atraumatic extraction to preserve the intact periodontal ligaments
and Hertwig's root sheath should be considered.

stem cells are capable of self-regeneration, unlimited division and differentiation, and have ab immunomodulatory character.
Thus, any periodontal ligament
tissue which later might develop coronally to the notch in the root surface will be formed de novo and clearly distinguishable in the histological sections.

[PAR.sub.1] involvement in periodontal tissue metabolism has been suggested by several in vitro studies which have shown expression of its receptor by the periodontal cells such as human gingival fibroblasts, gingival epithelial cells, periodontal ligament
cells, osteoblasts, and monocytic cells and presence of its possible activators, thrombin, plasmin, MMPs, and gingipains, in the periodontal environment (Table 2).
When an orthodontic force is applied to a tooth, it creates areas of tension and compression in the periodontal ligament
The periodontium has a limited capacity for regeneration, probably due to changes in periodontal ligament
stem cells (PDLSCs) phenotype.
Evaluation of Platelet-Rich Plasma Effect at different times and concentrations on periodontal ligament
fibroblast and osteoblast viability
If left untreated, gingivitis will progress to periodontitis, a gradual destruction of the structures that hold teeth in position These structures are gingiva, bone, periodontal ligament
and cementum, a bonelike substance covering the root of a tooth.
Periodontal tissues include alveolar bone, periodontal ligament
, cementum and gums.
The periodontitis is an inflammatory disease in periodontal tissue involving gingiva, cementum, periodontal ligament
, and alveolar bone.
