[Densitometric investigation of the dynamics of bone defects regeneration in surgical treatment of chronic periodontitis].

Apicotomy of 105 teeth of 78 patients with chronic periodontitis has been performed. The periapical defect were filled with two kinds of osteoplastic matter: the first group was treated with demineralised bone matrix of newborn pigs (DBMNP), the second group with artificial hydroxyapatite, while both matters were enriched with platelet rich plazma (PRP).As a third, control group, cases. The defects of which were not filled with osteoplastic matter, were investigated. The dynamics of the regeneration of bone defects was studied based on the data of densitometric investigation. The results of objective observations have revealed high efficiency of surgical treatment of chronic periodontitis with the filling with DBMNP in combination with PRP.
