The influence of microbiota on the development and course of inflammatory diseases of periodontal tissues.

An important feature of the functioning of the organs and tissues of the oral cavity is the fact that all processes that take place in it are carried out in the constant presence of various microorganisms that cause the development of pathological processes in the body or are associated with them. In the pathogenesis of chronic generalized periodontitis, dental plaque penetrates the bottom of the gingival sulcus, penetrating under the epithelium into the stroma of the connective tissue, causing its inflammation. Bacteria produce a number of toxic substances that have a toxic effect on surrounding tissues.

Endogenous intoxication in development of experimental periodontitis of bacterial-immune genesis.

Introduction: Excessive lipoperoxidation is accompanied by accumulation of peroxidation products and depletion of antioxidant re-serves, which cause hyperenzymemia and the accumulation of toxic substances. The level of endotoxicosis is determined by the content of hydrophilic and hydrophobic products in the blood.

Aim: To define the pathogenetic role of endogenous intoxication in the dynamics of development of experimental periodontitis of bacterial-immune genesis.

ANALYSIS OF THE ADVISABILITY OF USING DIFFERENT TYPES OF BASE PLASTICS BY STUDYING THE NEEDS OF THE POPULATION IN REMOVABLE PROSTHESIS.

Objective: The aim: To determine the needs of the population of the Ternopil region in prosthetics with removable orthopedic dentures and to study the physical and technological properties of different types of base plastics.

Patients And Methods: Materials and methods: The needs of Ternopil and Ternopil region population in removable prosthetics were studied on the basis of consolidated annual reports of city and district dental clinics of Ternopil region. Base dental plastics «Ftoraks» (Stoma, Ukraine) and «Villacryl H Plus» (Zermapol, Poland) were used to study the physical and mechanical properties (deformations during compression and tension).

MORPHOLOGICAL CHANGES OF PERIODONTAL COMPONENTS UNDER EXPERIMENTAL LIPOPOLYSACCHARIDE PERIODONTITIS COMBINED WITH HYPERTHYROIDISM.

Objective: The aim: Investigate structural changes in the tissues of the periodontal complex under the condition of experimental lipopolysaccharide periodontitis combined with hyper¬thyroidism.

Patients And Methods: Materials and methods: The studies were performed on adult white male rats, which simulated periodontitis combined with hyperthyroidism. Periodontal tissues were subjected to morphological examination on the 22nd day of the experiment.

Biological compatibility of metal structures of dentures made from multiple melted alloys.

Unlabelled: The issue of reuse of metal alloys in dentistry raises debatable questions about their impact on the human body.

Aim: The aim of the study was the evaluation of the biocompatibility of metal structures of dentures made from cobalt-chromium and nickelchromium alloys Remanium GM 700 and Remanium CSe after repeated vacuum remelting.

Materials And Methods: Clinical study and treatment with fixed prostheses based on Remanium GM 700 and Remanium CSe were performed among 120 patients aged 25-60 years.
