REPARATIVE REGENERATION OF PERIAPICAL TISSUES IN CHRONIC GRANULOMATOUS PERIODONTITIS UNDER THE INFLUENCE OF COMPOSITION BASED ON CALCIUM HYDROXYAPATITE.

OBJECTIVE: The aim: To establish the dynamics of reparation processes in periapical tissues in chronic granulomatous periodontitis under the influence of the developed composition based on calcium hydroxyapatite in comparison with the generally accepted drug MTA. PATIENTS AND METHODS: Materials and methods: The main group included 52 individuals, and the comparison group - 19 patients with chronic granulomatous periodontitis. In the first experimental subgroup, patients were obturated of the tooth root apical area with the proposed composition, and in the second experimental subgroup patients were performed obturation of the root canal apical area with additional transcanal withdrawal of the composition into the periapical area. In the comparison group, the tooth root apex was obturated with MTA material. RESULTS: Results: Clinical studies have shown that the composition based on calcium hydroxyapatite, having osteoconductive, antioxidant and anti-inflammatory properties, activates the synthesis of organic and mineral components, that promotes the bioreparation and regeneration processes of periapical tissues in chronic granulomatous periodontitis, which occurred most intensively during the first 6 months after treatment. At the same time, with additional transcanal removal of the filling composition based on calcium hydroxyapatite into the periapical area in patients with chronic granulomatous periodontitis with acquired wide tooth root apex was observed in 1.6 time better results than the method of creating an apical root canal obturation (p <0,05), indicating a high therapeutic effect. CONCLUSION: Conclusions: Composition based on calcium hydroxyapatite, having osteoconductive, antioxidant and anti-inflammatory properties, activates the synthesis of organic and mineral components, which promotes the processes of bioreparation and regeneration of periapical tissues, especially in the early stages. And additional transcanal removal of the filling composition into the periapical space causes the acceleration of the period of periodontal tissues revitalization, bioreparation and regeneration compared to the creation of the apical obturation within the physiological tooth root apex.

PATHOGENETIC MECHANISMS OF COMORBIDITY OF SYSTEMIC DISEASES AND PERIODONTAL PATHOLOGY.

OBJECTIVE: The aim: Of the study is to analyze the literary data regarding evaluation of the pathogenetic mechanisms of the interaction of systemic diseases and periodontal tissue damage, conducted on the basis of scientific researches of Ukrainian and foreign scientists. PATIENTS AND METHODS: Materials and methods: Bibliosematic and analytical methods were used in the research. The materials of the exploration are international experience in the study of pathogenetic mechanisms of the interplay of pathology in the cardiovascular, respiratory systems, diseases of the gastrointestinal tract and chronic generalized damage of periodontal tissues. CONCLUSION: Conclusions: It is important to search for new modern methods of diagnosis and individual approach to primary and secondary prevention of changes in periodontal tissues on the background of general pathology. The only way to solve this problem is a detailed study of somatic and dental history, changes in all body systems, on the basis of which it is possible to create a reasonable set of individual preventive measures and improve the treatment of periodontal disorders.

Periodontal status in patients with diseases of hepatobiliary system, burdened with tobacco and drug addiction.

OBJECTIVE: The aim: To study the effect of drug addiction and smoking on the status of periodontal tissues in patients with hepatobiliary pathology. PATIENTS AND METHODS: Materials and methods: 58 smokers, 63 drug addicts with hepatobiliary pathology were examined and 92 persons of comparison group (with inflammatory periodontal diseases affected by hepatobiliary pathology, without addiction). Examination of patients included determination of iodine number by Svrakov, S-L and Stallard hygiene indices, PMA index and index PBI. RESULTS: Results: The results of examination of smokers are worse in patients with cirrhosis than in patients with chronic toxic hepatitis and non-alcoholic steatohepatitis and also the results of these two groups was significantly worse than that of the comparison group (iodine number by Svrakov - 1,4 times and 1,3 times higher, PMA index - 1,7 times and 1,4 times worse, in accordance). The results of the study showed that drug addicts patients are worse values in patients with cirrhosis than in patients with chronic toxic hepatitis and non-alcoholic steatohepatitis and also the results of these two groups was significantly worse than that of the comparison group (iodine number by Svrakov - 1,5 times and 1,4 times higher, PMA index - 1,7 times and 1,5 times worse, in accordance). CONCLUSION: Conclusions: Presence of hepatobiliary pathology in smokers and drug addicts increases the risk of periodontal diseases.

The role of small intestinal bacterial overgrowth in the pathogenesis of hyperlipidemia.

OBJECTIVE: Introduction: Small intestinal bacterial overgrowth may cause the hyperlipidemia appearance by enterohepatic circulation disturbance which evolves on the background of the early bile acids deconjugation with further endotoxin production and oxidative stress in the liver with hyperproduction of cholesterol and atherogenic lipoproteins. The aim: the determination of prevalence and features of SIBO in a series of patients with hyperlipidemia and in control subjects. PATIENTS AND METHODS: Materials and methods: Nineteen patients with hyperlipidemia and ten control subjects were studied. Small intestinal bacterial overgrowth was assessed by a lactulose breath test. Such biochemical markers as CRP, ALT, AST, GGTP, apolipoprotein B, bilirubin, cholesterol and lipid profile were determined. Except the routine interpretation of lactulose breath test, which contains the SIBO detection, small intestinal transit time and hydrogen level evaluation with next comparison between groups of patients was realized. RESULTS: Results: Small intestinal bacterial overgrowth was present in 78.9% of patients with hyperlipidemia and 40% in control subjects. The maximal dose of H2 was particularly higher in patients with hyperlipidemia in comparison with control group (94,7±13,69 vs. 36,13±5,4). There was a strong correlation between AST level and SIBO existence in both groups (r=1). Positive connection between LDL, TG, VLDL and the dose of exhaled hydrogen on 120 minute (r=0.6, r= 0.62, r=0.7 respectively) and strong negative correlation between HDL and 120 minute dose (r=-0.74) in main group was marked. CONCLUSION: Conclusions: Patients with hyperlipidemia have a higher prevalence of small intestinal bacterial overgrowth and there is a relationship between H2 rate and LDL, TG, VLDL.
