RADIOGRAPHIC PICTURE OF STRUCTURAL CHANGES IN THE ALVEOLAR BONE OF PATIENTS WITH GENERALIZED I-II DEGREE PARODONTITIS ON THE BACKGROUND OF OSTEOPLASTIC INJECTION THERAPY

Abstract

Background. Nowadays, the problem of parodontosis effective treatment is really significant which is proved by the dynamics of growth among the patients of Ukrainian population. Currently, in the modern parodontosis treatment new technologies are widely used to help optimize the processes of regeneration in the parodontal tissues. Recent literature increasingly highlights some results for dental application of platelet –rich plasma (PRP), which effectiveness is scien-tifically justified, especially if it is applied to the osteoconductive materal. Objective: Follow the dynamics of changes in radiographic parameters of patients in the comparison groups during the complex treatment of generalized I-II degree parodontitis, including osteoplastic materials injection. Material and methods. Treatment of patients was effected in outpatient setting. The results of clinical and radiographic parameters during treatment and examination of 103 patients (both men and women, aged 25– 50), (33 patients in the control group, 36 – in the I main group. 38 – in the II main group). The control group underwent the traditional comprehensive treatment of generalized I-II degree parodontosis with the extract aloe injection in the soft tissue of the transitional fold in the projection of the causative teeth. In the first main group of traditional treatment was accompanied by subperiosteal injection point of introduction to the parodontitis tissues PRP-GEL (based on projection OF 0.3-0.5 ml per tooth). The treatment included 3 injections (with 1 week interval). The second main group, along with the comprehensive treatment underwent concomitant injection of osteoplastic treatment of parodontal tissues and Isuspension of PRP preparation Biomin GTIS, introduced separately pointwise in the parodontal tissue at the rate of 0.3 ml in the projection of one tooth segment. Pain relief was effected by the anesthesia infiltration of 0,5 % lidocaine. All patients underwent the orthopantomography and target radiography. These examinations were made before treat-ment and in 1,3,6 and 12 months after treatment. Results. Analysis of radiographic changes against the background of the complex treatment of patients with generalized I-II degree parodontitis confirms the effective use of local injections of osteoplastic materials (e.g. the PRP gel and sus-pension Biomin GTIS). The most active processes of bone structures restoration after osteoplastic materials injections were distinguished in the second min group 38 patients ), the administration of a mixture including PRP-gel and powder slurry Biomin GTIS, which combined demonstrate the effects of osteoinductive nd osteoconductive characteristics and antiseptic and anti-inflammatory effect due to silver ions release. It has resulted in a faster subsiding of local inflammatory reactions, re-duced number of postoperative complications and created optimalconditions for the preservation of volumes and par-tial regeneration of the lost alveolar bone. Positive outcome was reported in 37 patients and in I main group in which despite the absence of the bone tissue growth, the volume maintained, due to osteoinductive and reparative effect of PRP-gel. In the control group (33 patients), the process of gradual loss of bone continued, which is a cahacteristic of chronic generalized parodontitis. The results are confirmed by radiography anthropometry.
