Aim. Analysis of complications in the treatment of complicated caries.Materials and methods. Cone beam computed tomography results of 200 patients aged 21 to 64 years. The teeth were divided into frontal and chewing groups. The quality of the performed endodontic treatment was assessed.Results. During the analysis of the results of cone-beam computed tomography, the following complications of endodontic treatment were revealed: incomplete obturation of the root canal, removal of material beyond the apex of the tooth root, missed root canal, fracture of the instrument in the root canal. The regularity of their frequency was established, depending on the part of the jaw in which the tooth was located.Conclusions. Conducting cone-beam computed tomography during diagnosis, during treatment, will eliminate complicationsassociated with a lack of diagnostic imaging, effectively assess the success of the treatment for timely action.

Aim. To evaluate the clinical efficacy of long-acting remineralizing medical means in the complex prevention of caries in pregnant women.Materials and methods. The study was conducted on the basis of the Department of Therapeutic Dentistry of the Kuban State Medical University of the Ministry of Health of Russia. A total of 87 people were examined, aged 24 to 37 years, with different levels of oral hygiene 84 patients confirmed their consent to the treatment and prophylactic measures, after which three working groups were formed depending on the long-acting remineralizing agents used “Clinpro-XTVarnish” manufactured by 3MESPE, “Schmelz-versiegelungsliquid” manufactured by HUMANCHEME, “InnoDent Repair” manufactured by InnoDent LLP respectively) and 1 control group. The assessment of the dental status of pregnant women was carried out using indices: CFE, Fedorov-Volodkina oral hygiene index (HI), gingivitis index GI (Loe H., Silness J.).Results. According to the data of a clinical study, it was determined that a high quality oral cavity sanitation with concomitant use of long-acting therapeutic and prophylactic agents increases the effectiveness of preventive measures in pregnant women.Conclusions. The data obtained indicate the achievement of a long-term preventive result, which makes it possible to recommend the investigated fluorine-containing agents for remineralization of hard dental tissues in order to control the state of the oral cavity of women during pregnancy.

The article discusses the evaluation of the effectiveness of the influence of thermal vibration effects on the bending strength and surface hardness of composite filling materials.The study was conducted on the basis of the Department of Therapeutic Dentistry of the Kuban State Medical University, as well as at the Krasnodar Instrument Plant “Cascade”. The samples under study were made according to the group affiliation from three different composite materials: Estelite Sigma Quick, Filtek Bulk Fill Posterior Restorative and DentLight. The bending strength was evaluated on the “MIP-10” testing machine of the company “NPK TECHMASH”. Determination of the surface hardness according to Vickers was carried out on the device PMT-3 of the company “LOMO”.According to laboratory studies, a statistically significant increase in flexural strength and surface hardness according to Vickers was determined for all samples of composite materials subjected to thermal vibration before polymerization.The data obtained indicate an increase in the strength characteristics of composite filling materials as a result of thermal vibration exposure before their polymerization, which increases the service life of composite fillings and reduces the risks of secondary caries formation after filling.

Background. The treatment of pulp inflammation takes an important place among modern dentistry problems. Depulpated teeth in some cases become chronic source of infection. They could also cause an odontogenic infection of the maxillofacial region. In this regard, it is important to use conservative methods of treatment to eliminate the inflammatory process in the dental pulp and preserve the vitality of the tooth.Aim. The aim of this study is to collect and systematize the information about modern aspects of the conservative treatment of pulp hyperemia that is presented in scientific articles and to study the effects and impacts of bioactive materials on pulp tissues.Materials and methods. A search was made for literature sources in the database: PubMed, dissercat.com, elibrary.ru, cyberleninka.ru using the keywords «caries», «pulp hyperemia», «pulpitis», «bioactive materials» with a choice of article types «Clinical Trial», «Meta-Analysis», «Review», «Systematic Review».Results. After analyzing the literature review, an idea was obtained about the pathogenesis of the pulp at various stages of inflammation, criteria for its clinical assessment of the morphological state, pathophysiological and cytological processes of the pulp when exposed to bioactive materials. A modern classification and review of bioactive materials used in the treatment of pulp hyperemia is presented.Conclusions. Studying the literature on the morphology and pathophysiology of the pulp, on its reserve possibilities of the regeneration plan, it was found that the inflammation in the dental pulp is reversible. This requires modern therapeutic materials that cause the reverse development of inflammation in the dental pulp. A conservative method of treating pulp hyperemia involves using materials that restore the structural and functional properties of the pulp, so preserve its vitality. This review article provides an overview of the materials used in the conservative treatment of pulp hyperemia according to Russian and foreign literature.
