Migration and division of progenitor cells populations in the periodontal ligament after wounding.
Proliferative effect of growth factors TGF-beta1, PDGF-BB and rhBMP-2 on human gingival fibroblasts and periodontal ligament cells.
In some cases, the inflammation and infection of the pulp may extend beyond the tooth to the periapical tissues of the periodontal ligament.
Millennium Dental Technologies is the first and only company to receive exclusive clearance for a complete periodontal disease treatment protocol, the Laser Assisted New Attachment Procedure (LANAP), for cementum-mediated new periodontal ligament attachment to the root surface in the absence of long junctional epithelium.
It can initially start as transient inflammatory resorption where damaged areas of the periodontal ligament are colonised by tissue-resorbing cells.
This space is necessary to provide a channel for the migration of progenitor cells towards and onto the detoxified root surface hence differentiation of cementoblasts, formation of new cementum and periodontal ligament is desired (29,30).
The dental record of the child had an orthopantomogram (Fig 2a) made a year previously, which revealed that teeth 14, 12, 21, 22 had not been lost then, however they showed excessive periodontal defects with widened periodontal ligament space, loss of crestal bone height and no caries.
In order to simulate the periodontal ligament, a thin layer of silicone (0,2 mm) was applied along to the root surfaces.
Periodontal regeneration is perhaps one of the most complex to occur in the body since at least six tissues are involved: the gingival epithelium, gingival connective tissue, periodontal ligament, tooth root surface cementum, alveolar bone and corresponding vasculature.
In vitro and in vivo data has shown that GEM 21S acts by stimulating the recruitment and proliferation of bone and periodontal ligament cells, promoting revascularization and providing an osteoconductive, highly porous, three-dimensional calcium phosphate matrix or scaffolding to facilitate new bone formation and periodontal regeneration.

Radiological examination signs of periodontal ligament obliteration were recognized, again in 1/3 of the patients.
