Vascular response of the periodontal membrane after replantation of teeth

摘要: Thirteen replanted maxillary central incisors were studied by means of histologic and cleared sections to evaluate the pattern revascularization periodontal membrane modification its vasculature due root resorption, dentoalveolar ankylosis, periapical processes. Early reparative activity was noted in apical cervical parts where proliferating vessels intermingling with cells interrupted collagenous fibers. These areas corresponded those receiving a better vascular supply after replantation. The middle third membrane, however, showed scarcity or absence as result delayed revascularization. Root processes changed both tissue specificity supply. Revascularization pulps vacuolar degeneration lack nutrition.
