The aim of this review was to examine the techniques for performing keratinized gingival augmentation and grafts, as well as the materials used, which are often required to ensure proper wound closure. Tissue engineering of the oral mucosa represents an interesting alternative to obtain sufficient autologous tissue to repair oral soft tissue defects using biodegradable scaffolds and can improve vascularization and epithelialization, which are critical for successful outcomes.

The purpose of this systematic review of the literature is to detail the main physical, chemical, biological, operational, and other significant properties of bioceramic materials used in endodontic practice ю Фccording to the studied literature, we can say that bioceramic endodontic materials have satisfactory performance properties, are characterized by antimicrobial action and alkaline pH, have optimal biocompatibility and bioactivity, which indicates the feasibility of their use in the clinical practice of a dentist-endodontist.

The purpose of this review article is to analyze the current data on the use of antiseptics in the treatment of periodontitis, development of resistance of periodontopathogens to antiseptic agents using the example of chlorhexidine, cetylpyridinium chloride and hexetidine. Periodontal pathogens are an integral part of the commensal microflora of the oral cavity, but under certain conditions and under the influence of etiological factors, their number begins to progressively grow, which increases the risk of initiation of periodontal diseases through the formation of aggressive biofilm on the teeth.Materials and methods. Тhe study of publications was produced in the electronic databases such as PubMed and Google Scholar in the course of a systematic review of the literature. Included articles contain information about antiseptic agents which are chlorhexidine, cetylpyridinium chloride and hexetidine, as well as their effect on periodontopathogens and the possibility of developing resistance in them against these antiseptics.Results. 127 articles were viewed during the review. After analyzing the literature for inclusion criteria, the total number of publications has become 94.Conclusions. Аccording to the analyzed data, we have found that antiseptic treatment of the oral cavity and lesions in periodontitis is an integral part of the treatment of this inflammatory disease, as an addition to the mechanical treatment protocol. Chlorhexidine in local forms of delivery has shown particular activity against periodontopathogens.
