[Chemiluminescence of whole saliva in antioxidant treatment of prosthetic bed tissues].

Inflammatory reaction is always accompanied by increased intensity of free-radical oxidation, especially when the phenomena of hypoxia and microcirculatory disorders that occur during the development of side-effects of acrylic removable dentures. This study determined the effectiveness of adaptogens, antioxidants in the complex treatment of diseases of tissues prosthetic field and their influence on the processes of LPO in whole mixed unstimulated saliva. Formed in the reaction to initiate the process of oxygen radicals (OH, RO, O(2)), initiate the formation of lipid peroxide radicals RO(2) biological substrate, the recombination of which leads to the emergence of unsustainable tetroxids, which decays with the release of light quanta. This luminescence is recorded as an amplified current of the photomultiplier, the registration systems. The results suggest the intensive formation of free radicals and peroxides in diseased tissue prosthetic field. Probably the main reason for increasing free-radical oxidation is the release of peroxidase from the crumbling inflammation, phagocytes (mainly neutrophils). The process of peroxidation contributes to an increase in blood supply to inflamed tissues, leading to local enrichment of oxygen, as well as toxic effects of acrylic bases of partial and complete removable dentures in the prosthetic field of tissue. Effect of antioxidants in combination with traditional treatment in 70 patients with periodontal disease and prosthetic bed was assessed by chemiluminescence analysis of whole mixed unstimulated saliva. The level of lipid peroxidation and chemiluminescence activity exceeded the normal values in the 1,5-2 - twice before the treatment. After treatment with antioxidants, these parameters decreased and increased during remission. Thus, studies to determine the status of saliva chemiluminescence method to treat and monitor the dynamics after treatment of periodontitis tissues supporting teeth prosthetic field in the control group and the main observation, revealed the following pattern: the approach of all the indices to normal in patients with a core group, which corresponded to the clinical dynamic index parameters of periodontal tissues supporting teeth prosthetic field, and a similar core group of the positive dynamics of the intensity values of chemiluminescence-indicators in the control group up to 3 months of observation, with a significant deterioration of the same indicators at a later time dynamic monitoring.

[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.
