Alexandrov M.T., Akhmedov A.N., Artemova O.A., Namiot E.D., Potrivaylo A.
Abstract
The aim of the conducted research was to study the practical application of photometric measuring devices with the use of fluorescent technologies. Photometry is a set of methods for molecular absorption spectral analysis based on selective absorption of electromagnetic radiation in the visible, infrared and ultraviolet regions by molecules of the component being detected or its compound with a suitable reagent. During the research, 10 different dental prosthetic designs were measured before and after cleaning. The purpose of the experiment was to give the objective evaluation of the different dental prosthetic designs for their further use in a clinic. The InSpectr M device was used for the measurements and the specialized program MedGun was used to convert the received results into a convenient and understandable format. Prostheses were measured in the points where they were the most vulnerable to bacteria. At first, prostheses were measured in the same state they were received, then they were cleaned with the use of the toothpaste. After cleaning the aerobic index and fluorescence intensity of the prostheses were re-measured. A statistically significant difference for the measured values is shown and the practical applicability of measurement methods based on fluorescent technologies for the assessment of the hygienic state of dental prosthetic structures is proved.

MICROTEST FOR THE DETERMINATION OF THE AMYLOLYTIC ACTIVITY OF SALIVA ALPHA-AMYLASE
Godovalov A.P., Yakovlev M.V., Zadorina I.I.
Abstract
It is known that the concentration of alpha-amylase in saliva can determine its catalytic activity, the decrease of which occurs during various pathological processes in the oral cavity. The overwhelming number of methods for determining the catalytic activity of enzymes involve the use of a large volume of reagents and samples, which makes it difficult to study saliva in large groups. The purpose of the study is to evaluate the possibility of using the microvariation of the reaction to determine the activity of saliva alpha-amylase, as well as to analyze the dependence of the enzyme activity on its concentration. Materials and methods. Saliva was obtained from 15 people with intact periodontal disease and the dentition, without somatic pathology. For in vitro studies, alpha-amylase solutions were prepared with an enzyme concentration of 10; five; 2.5; one; 0.5 and 0.25 mg / ml ex tempore. To save samples and reagents, the volume of the reaction participants was proportionally reduced. The further analysis procedure was carried out according to the instructions of the manufacturer of the «AMYLASE-VITAL» reagent kit to determine the activity of alpha-amylase. Statistical analysis of the results was performed using the Student’s t-test in the program Statistica 7.0. Results. The comparability of the results of determining the activity of alpha-amylase using the classical and microplate variants of the reaction is shown. With an increase in alpha-amylase concentration from 0 to 2.5 mg / ml, a directly proportional increase in enzyme activity is observed. In the case of an increase in the concentration of alpha-amylase above 2.5 mg / ml, a decrease in its activity is shown, which may be due to the precipitation of a part of the enzyme. The activity of the enzyme in saliva of practically healthy individuals using the microvariation of the reaction was 528.6 ± 2.4 U / l. In conclusion the use of a microvariant of the reaction for determining the activity of alpha-amylase may be justified for a large number of subjects. A linear dependence of the enzyme activity on its concentration in the range of 0-2.5 mg / ml is shown.

Shugailov I.A., Agafonova A.V., Sergeeva Y.I., Mirgazizov M.Z.
Abstract
A method of combined anesthesia using inhaled premedication with a xenon-oxygen mixture was developed, followed by local anesthesia with articaine drugs in pediatric outpatient dental practice. 61 children, from 2 to 9 years old, who were referred for treatment under anesthesia due to an irresistible fear of dental surgery, were admitted for treatment. The developed method allowed all interventions to be carried out in conditions of emotional comfort and stable vegetative indicators in most patients. As a result, in 92% of children sent for treatment under anesthesia, they managed to undergo treatment with combined analgesia with a preserved consciousness. Thus, the developed method of combined anesthesia based on premedication with a mixture of xenon and oxygen combined with local anesthesia is effective, safe and promising for wideSpread use in children’s dental practice.

Lashko I.S., Tsarev V.N., Olesov E.E., Mirgazizov M.Z., Glazkova E.V., Olesova V.N.
Abstract
Means of antiseptic effects on the microflora of the oral cavity in the treatment of periodontitis are constantly being improved in connection with the non-guaranteed treatment results and the polyetiology of the disease. A microbiological study was conducted to substantiate the antimicrobial effect of the drug Krezacin denta of different concentrations in relation to a number of periodontopathogens and fungi of the genus Candida. The active substances of Krezacin dent are Krezacin 3% or 5% and metronidazole. The study was conducted in a bioreactor with automatic determination of the optical density of the culture of periodontopathogens in the presence of drugs. An identical study was conducted using the drug Metrogil dent. It was found that Metrogil denta has practically no effect on the culture of Candida albicans, while Krezacin denta inhibits the growth of Candida albicans at a concentration of 0.5% and 1.5% by 13.6%, and in more pronounced concentrations - up to 26, 6% Regarding S.aureus, Metrogil denta reduces the optical density of the culture of the indicated periodontopathogen by 34.7%, Krezacin denta by 49.8% at a concentration of 5.0%. S. Constellatus decreased its concentration in the presence of Metrogyl dent by 12.4%, while in the presence of Krezacin dent by 30.9%, starting from a concentration of 3%. Thus, we can state a more pronounced antimicrobial effect of Krezacin dent in comparison with Metrogil dent.

Arsenina O.I., Grudyanova A.I., Nadtochiy A.G., Popova N.V., Karpanova A.S.
Abstract
The data of the ultrasonic gingiva thickness scanning are compared with the data obtained using the colorimetric probe system. We revealed that the white probe corresponds to the gingiva thickness - less than 0.5 mm; the green probe - the gingiva thickness from 0.6 to 0.9 mm; the blue probe - the gingiva thickness from 1.0 to 1.5 mm. If none of the probes is visible through the gingiva, such a biotype is regarded as very thick and its thickness reaches more than 1.6 mm. Thus, the colorimetric probe system can be used by a doctor for gingiva thickness examination the in the absence of an expensive ultrasound scanner.

Abstract
At present, there is an increase in the number and proportion of older persons. Accordingly, the requirements to ensure the necessary quality of life of this category of population are increasing. This applies, inter alia, to the issues of their rehabilitation after various diseases and injuries. Among the injuries of the bones of the facial skeleton, the most common type are fractures of the lower jaw. The purpose of this work is to analyze the prevalence, clinical features of mandibular fractures in patients of the older age group and the effectiveness of existing methods of their treatment, according to modern literature data. RSCI, PubMed, Medline databases for the period 1960 - 2019 were used to compile the review. Results. Data from 687 literary sources were used in the preparation of this review. Their analysis shows that older patients represent a stable and statistically significant group, in the General structure of victims with mandibular fractures, and having a number of clinical features, as a result of which conventional methods of treatment are often ineffective. The most common concepts of medical care for this category of patients are characterized. Conclusion. To date, there are no reliable randomized clinical trials based on sufficient statistically material that allows to substantiate the advantages of a particular method of treatment of older patients with mandibular fractures at the evidence level, which requires the continuation of the relevant multicenter clinical studies.

MODERN AASPECTS OF A ROOT CANAL INSTRUMENTATION
Pedorets A.P., Pilaev A.G., Terpigoreva L.P., Ponomareva N.A.
Abstract
The authors of the article consider various approaches to the preparation of the apical part of the root canal. They analyze the nature of the microbial flora of the channel, the peculiarities of its distribution within the channel and beyond. In addition, the authors note the role of root cement in the extracanal arrangement of the microbial film. The article provides an analysis of such concepts as “ensuring the apical patency” and “opening the apical foramen.” The differences between these concepts is emphasized, which is of fundamental importance both for determining the limits of the apical preparation and for understanding the essence of the pathological processes in the periodontal teeth with the preserved and destroyed apical constriction. Based on their own research and data from the world endodontic literature, the authors offer their recommendations on instrumentation of the cement canal depending on a particular clinical situation.
