Treatment of complicated forms of caries remains the most important task in the practice of a dentist. Tooth extraction in the absence of endodontic treatment or its improper conduct leads to a violation of the quality of human life. At the present stage of development of endodontics-the science of the art of tactile sensations in combination with high-tech methods, to the main material and technical component: Ni-Ti-tools, ultrasound, operating microscope, etc.added a new high — tech diagnostic technique-cone-beam computed tomography (CBCT). With its help, increases the percentage of successful outcome of treatment in clinical situations that previously seemed hopeless. No endodontic intervention can be considered adequate without detailed monitoring.

Relevance of a problem of the combined defeats of the parodont and endodont it is caused by high prevalence of pathology and lack of uniform approaches to complex treatment of this category of patients that has defined a research objective: optimization of methods of treatment the endoparodontalnykh of defeats taking into account pathogenesis of a disease. The research was conducted in 2 groups — main (n = 12) and comparisons (n = 13) which were made by patients with primary defeat of the parodont and secondary involvement in process of the endodont at which examination with use of a computer conical and beam tomography and the automated measuring system «Florida Probe» is conducted, and treatment included basic therapy of pathology of the parodont, endodontichesky treatment and the supporting therapy of the parodont. In the main group the basic and supporting therapy of pathology of the parodont included processing the parodontalnykh of pockets the VectortmParo system. The received results in the form of disappearance of bleeding, mobility of teeth, reduction of depth of a parodontalny pocket to values of ≤3,5 mm and restoration of structure of a bone tissue up to 1/3 lengths of a root with preservation of these indicators on the remote terms of observation in the main group in comparison with indicators of group of comparison «vector therapy» in treatment of patients with endoparodontalny defeats demonstrates efficiency of inclusion.

Research objective. To assess the state of oral tissue in patients with paranoid schizophrenia of continuous flow according to biochemical indices of mixed saliva and to compare with clinical parameters. Material and methods. 57 patients with continuous paranoid schizophrenia were divided into 5 groups according to age. The rate of salivation, pH was calculated, the activity of AST, ALT, APF, LDH, total protein, IL-1β, —4, —6, —10, TNF-α was determined in saliva. All the results obtained were processed by variational statistics, correlation analysis by Spearmen. Results and discussion. Patients with paranoid schizophrenia of the continuous course revealed an unfavorable clinical status of the oral tissues, which correlates with the parameters of mixed saliva.

A new technique for evaluation of adhesive bond strength of fiber posts is presented. It called by the authors the “torque-out” test. Unlike the known test methods, in which a tensile or compressive load is applied to the sample, the load is produced by the torque. Samples for testing of a specific combination of post and cement can be manufactured chairside without using of special equipment. A compact installation developed by the authors designed to assess the adhesive bond strength of the connection by the value of the maximum torque is described. Using numerical modeling, the stress-strain state that occurs in the samples during push-out and torque-out tests was compared.

It this scientific abstract was studied and measured the waviness assessment of healing abutment for different producers. The surface area and waviness assessment have paramount value for assessment of probability adhesion of microorganisms. When was studied the waviness assessment of healing abutment, have revealed system with minimum rough surface and have compared by using the scanning electron microscopy. Summing up the result of our science work, it should be noted that the first system has optimum conditions for adhesion hedging microorganisms.

For a number of systemic diseases accompanied by changes in the state of organs and tissues of the oral cavity, manifested more active over carious diseases, lesions of the oral mucosa and periodontal, dental plaque formation. Correlation analysis carried out in the ratio of chemical elements in dental plaque in patients with essential hypertension (EH), diabetes mellitus (DM) and chronic pyelonephritis (KP). In individuals with different somatic diseases established differences in the ratio of chemical elements in the dental plaque. It proved that for hypertensive patients characterized by an increased content of cadmium, vanadium, selenium, and molybdenum, with reduced content of rubidium, silver, barium and chromium, diabetics have a higher content of copper and cadmium, and patients with chronic pyelonephritis distinguishes high content of cesium, indium, vanadium and arsenic under reduced content of silver, titanium, chromium, manganese and bromine. Solid dental deposits are irritating to the gum, the retention points are for the accumulation of dental plaque, disrupt the process of self-purification of the periodontal pocket. The elemental composition of dental plaque was studied on the equipment, the accredited Academy of Sciences to carry out research of the biological profile.

One of the most common complications of caries is chronic apical periodontitis. The microbial factor plays a leading role in the development of this pathological process. Consequently, the main task of endodontic treatment of chronic apical periodontitis is the qualitative antibacterial treatment of the root canal. At present, the use of ultrasound and laser is a promising direction for disinfection of root canals. With the help of a microbiological study of the microflora of the root canals of the teeth, a comparative evaluation of the antimicrobial effect of ultrasound and erbium-chromium laser was carried out before and after antibacterial treatment.

Тhe relevance of the research topic. Among the most important and not completely solved problems of therapeutic dentistry is the problem of full diagnosis and quality of endodontic treatment of patients with chronic periodontitis. Purpose. Determination of the norm of the optical density of bone tissue in the periapical region in the normal chewing groups of teeth in young people. Methods — to determine the parameters of the optical density in the focus of destruction, the data of radiovisiography and dental computed tomograms were analyzed. 68 people aged 20-30 years, with various forms of chronic apical periodontitis without endodontic intervention in the anamnesis were examined. Results.Тhe structure of the bone tissue of the upper and lower jaw has a different density, on dental computed tomography the density is 10-15 times higher than on radiovisiography, which is due to the peculiarities of the measurement program. Summary. The analysis of methods of radiovisiography and dental computed tomography allowed to determine the average values of normal optical density of bone periapical area of the masticatory groups of teeth of the upper and lower jaw, which are important in monitoring the quality of endodontic treatment of chronic forms of periodontitis.

In the practice of a dentist, a clinical situation occurs where the inflammatory processes are to varying degrees determined both in the periodontium and in the pulp of the tooth. A clinical case of endo-periodontal lesion in a 10-year-old child in the area of the upper first molar is described, which presents a difficult task, both in terms of diagnosis and treatment. The diagnostic value of CBCT was noted.

The relevance of the study is due to the need to develop a measuring tool for assessing the professional competencies of future dentists in quasi-professional activities (at the examination in the discipline «Stomatology»), which meets the requirements of vigilance and reliability. The purpose of the study was to substantiate the methodology for compiling a clinical situational task and check-lists for a professionally oriented exam. The material and methods are presented on the basis of the formed experience of compilation and approbation of clinical situational tasks and attached check-lists during the professional-oriented examination in the discipline «Dentistry» for three years at the Northern State Medical University. The results of the research reveal the process of developing a clinical situational task using the example of a task designed to assess the professional competencies of the examiners based on the results of studying the «Endodontics» module.

Along with the improving methods of medical tooling processing and root canals obturation development and study clinical effectiveness of drugs for intracanal use aimed at stimulation of tissue regeneration in the apical periodontium can be of strong interest.

The paper provides the results of chronic apical periodontitis treatment among 65 patients. The total number of teeth have been treated is 67. In the monitoring group (34 patients) complex treatment using intracanal drug-induced treatment of root canals with nanoargentum solution stabilized by sodium alginate and behind apical osteoplastic materials injection into periodontium tissues exemplified by the platelets enriched blood plasma has been applied.

It has been established that applying above mentioned combination promotes accelerated process of periodont osseous tissues reparation by 30 day and leads to reduction of treatment course. This is confirmed by measurements of osseous tissue optical density in cases of chronic apical periodontitis using methods of radiovisiography and computed tomography.

The article presents variants of the anatomical structure of the root system of permanent molars and clinical cases of detection of additional or atypically located root canals. Proper preparation of the tooth cavity and careful mechanical treatment of the canal mouths ensure optimal endodontic treatment. Quality control is carried out using optical devices and x-ray examinations.

A female patient, 20 years old, sought care at the dental clinic of Department of Cariesology and Endodontics, MSUMD after an accident, complaining that one of her teeth was broken. Upon clinical examination were diagnosed that the maxillary right central incisor was fractured in the middle-third of the crown, involving enamel and dentin without pulp exposure and without symptoms of concussion and contusion. Treatment options were discussed with a patient; due to a satisfactory amount of coronal tooth available, it was proposed to treat fractured tooth 1.1 with a direct composite restoration by Ceram.X ® duo through the use of diagnostic wax-up and silicone key. During DSD analysis were decided to harmonize the upper smile line by making direct composite build up of teeth 1.2, 2.1, and 2.2.

Today we are talking about Craniofacial microsomia or First and second branchial arch syndrome (CFM) as the second most common congenital malformation of the maxillofacial area after cleft lip and palate with extremely diverse phenotype and different types. First and second branchial arch syndrome amount to 11% of all defects in the formation of tissues and organs of the maxillofacial area. The aim of our study was to improve the quality of prevention and care for patients with CFM syndrome. Questionnaires developed for parents have included questions for the anamnesis of life and disease, hereditary factors, gestation course, the growth and development of children with such pathology. The data of 18 patients treated at the Department of pediatric maxillofacial surgery of MSMSU were analyzed. During the study exogenous and endogenous factors influencing the development of craniofacial microsomia syndromes (CFM) were identified. It was justified to use the ears of parents as a template of the missing organ of the child within preoperative preparation. It was revealed that the pathology of the urinary system and small abnormalities of the heart cannot be associated with the symptoms of CFM.
