Abstract
A light-ultrastructural study is carried out on labial attached and marginal gingiva from children (10-12 years) under orthodontic therapy with fixed appliances since eight months. We have observed fibro-angioblastic hyperplasia phenomenons in areas beside periosteum of alveolar crest. Various fibroblast lines are described: classic myofibroblasts, fibrocytes, young fibroblasts, activated fibroblasts and fibroclasts. We have interpreted vascular hyperplasia in relation to collagen tumover increase, making an enphasis in the important role of collagen endocytosis by fibroblasts in collagen tumover. Pericyte activation may be responsible of presence of different fibroblastic subpopulations.
