Relevance: to indentify if periodontal treatment which is presented by photoactivated disinfection (PAD) adjunctively to scaling and root planing (SRP) yield better outcomes than ozone therapy as an adjunct to SRP in periodontitis.Materials and methods: we examined 57 (mean age 49,3 ± 1,02) patients with chronic periodontitis, divided into groups, SRP + PAD, SRP + ozone therapy and SRP alone. Subgingival plaque samples were subjected to DNA extraction and real time PCR amplifcation for detection Porphyromonas gingivalis (Pg), Prevotella intermedia (Pi), Tannerella forsythensis (Tf), Treponema denticola (Td), Aggregatibacter actinomycetemcomitans (Aa). The amount of periodontopathogens and clinical parameters including plaque index, clinical attachment loss, pocket depth, bleeding on probing were measured at baseline, after 40, 90 and 180 days.Results: the results in groups of PAD+SRP and ozone therapy+SRP showed an improvement in all clinical parameters PI, BOP, PD, CAL and the quantity of Pg, Td and Tf compared to the control group during an observation period.Conclusion: the results showed additional benefts from PAD and ozone therapy as an adjunctive treatment to SRP for patients of chronic periodontitis.
Relevance. At present, the problem of the prevalence of overweight is becoming increasingly important in countries with a high standard of living, especially among the urban population. The social significance of this problem is determined by the threat of the development of diseases of the cardiovascular system, gastrointestinal tract, musculoskeletal system, as well as diabetes mellitus, which in turn are serious risk factors for the development and progression of periodontal pathology. One of the stages in the treatment of periodontal diseases is professional oral hygiene, the tactics of which, the effectiveness and stability of the results obtained also depend on taking into account the individual characteristics of the organism. Objective – to assess the effect of overweight (ICD 10 - K63.5) on the manifestation of periodontal disease and the clinical effectiveness of professional oral hygiene as a stage of initial periodontal therapy in the presence of diabetes mellitus. Materials and methods. The study involved 83 patients with diabetes mellitus type I aged 25 to 45 years with overweight and normal constitution, with chronic generalized periodontitis of mild and moderate severity. All patients underwent a standard complex of professional oral hygiene. Re-examination was carried out after 1 month. Results. The severity of clinical manifestations of periodontitis in patients with diabetes mellitus and overweight was higher than in the group of patients with normal constitution. The analysis of the effectiveness of professional oral hygiene as one of the stages of conservative periodontal therapy revealed differences in the response from the organism as a whole, and periodontal tissues in particular in the examined groups, demonstrating the pathological effect of excess body weight on the decrease in the effectiveness of hygiene measures. Conclusion. The identification of differences in the examined groups confirms the importance of overweight as an aggravating component in patients with periodontal disease and diabetes mellitus type I and dictates the need for a more detailed study of this parameter in the management of patients in this group and predicting treatment results, as well as creates the need for development and implementation of a comprehensive treatment and prevention strategy, including the assessment and monitoring of body mass index, promotion of a healthy lifestyle, elimination of modifiable risk factors.
Relevance. Autografts are nowadays the gold standard for soft tissue augmentation and gingival recession coverage. However, as this method has a number of significant disadvantages, xenografts of various origins are more frequently used in dental practice. The study aimed to conduct a comparative morphological assessment of crosslinked and non-crosslinked xenogenous scaffold biointegration quality at different healing times.Materials and Methods. The study used 108 Wistar rats (54 males, six months old, fat mass 462 ± 20; 54 females, six months old, fat mass 414 ± 7) and randomly divided them into three groups. Group 1 had a xenogenous collagen matrix (Mucograft) placed in the subperiosteal tunnel in the mandibular vestibule area; Group 2 had an acellular dermal collagen matrix (Mucoderm) implanted in the subperiosteal tunnel, group 3 had D-ribose crosslinked xenogenous scaffold (Ossix Volumax) placed in the subperiosteal tunnel.Results. The studied xenogenous materials showed different integration and biodegradation extents. By postoperative day 7, Group 1 (Mucograft) showed a more pronounced inflammation. Non-crosslinked collagen materials had almost completely resorbed by the 30th day of observation, while a crosslinked collagen matrix was detected as homogenous masses. By the 90th day, all groups demonstrated the formation of new connective tissue with different functional characteristics; only Group 3 histologically revealed microfragments of the graft.Conclusion. The study shows that the xenogenous crosslinked and non-crosslinked collagen membranes may promote an increase in soft tissue thickness to a different extent. However, it is essential to improve the available materials to reach an outcome comparable to the autologous soft tissue graft treatment result.
