In this paper, we give an overview of novel main-chain azobenzene-based fluorinated poly(arylene ether)s with different content of azo groups, aiming at providing a better understanding of the link between a number of N═N bonds and the macroscopic response of the material. We discuss chemical synthesis and molecular structure and report on a comprehensive analysis of the polymer properties, thermal behavior, and mechanical strength. We show that a higher content of azobenzene moieties reduces the mechanical strength of the polymer materials.

Patients And Methods: Materials and Methods: 216 people with the diagnosis of generalized periodontitis. Depending on the state of reactivity of the organism, the patients were divided into 3 groups: with normo-, hyper- and with hyporeaction.
Objective: Aim: The aim of this study was to determine the effect of application of drug with circadian activity (pioglitazone) for treatment of patients with periodontist.
Patients And Methods: Materials and Methods: Group I - 18 individuals with healthy periodontium. Group II - 12 participants with stage II, grade B periodontitis treated with a standard treatment protocol.
Unlabelled: Understanding the harmful effects of using tobacco products (cigarettes, electronic cigarettes (e-cigarette) or vape, IQOS, hookah, etc.) by various segments of the population is one of the important ways to improve the condition of the tissues of the oral cavity, since smoking is an important risk factor for the occurrence of chronic destructive periodontal diseases. The purpose of our work was a study of the relationship between the state of the oral cavity and the use of tobacco products in different age groups based on the conducted questionnaire.
