title: [Preliminary research on the prognosis of late reimplants with prior conditioning with a fluoridated solution].
abstract: The principal factors that affect the prognosis of a posttraumatic reimplantation are the length of the extra-alveolar persistence and the manner in which the extracted tooth is preserved. Both are fundamental for the maintenance of the fiber vitality of the periodontal ligament. The necrosis of these fibers cause ankylosis. It is observed that the conditioning of the radicular surface with fluoride solutions before the reimplantation is likely to slow down the evolution of radicular resorption. To evaluate the effectiveness of such methodology six cases of traumatic extractions, characterized by a length of extra-alveolar persistency (not longer than 24 hours), and unfavorable conditions of the preserved tooth have been treated by conditioning the radicular surface with the Na-fluoride solution before the reimplantation. Another group of reimplantation cases with the same characteristics have been examined without proceeding first to the radicular conditioning. The results of the study, although preliminary, verified the positive influence of the Na fluoride upon the radicular resorption.
