[The use of photoneuromodulation in the complex treatment of patients with burning mouth syndrome]. / Primenenie fotoneiromoduliatsii v kompleksnom lechenii bol'nykh s sindromom zhzheniia polosti rta.

The aim of the study was to evaluate the efficiency of photoneuromodulation in the complex treatment of patients with the burning mouth syndrome (BMS). Supervised were 120 patients with BMS at the age of 37-79 years (mean age 47.5±5.35 years), which were divided into two groups - the main group and the comparison group (n=60). All patients with BMS underwent complex treatment that included professional oral hygiene, training in rational oral hygiene and tongue, oral sanitation, rational prosthetics, consultation, treatment and follow-up with a neurologist, general treatment with the appointment of anti-anxiety drugs or antidepressants , vitamins of B group and vascular preparations. In the main group, after the drug treatment, a photoneuromodulation was performed - the effect of transcranial broadband red light, in the cervical collar zone and in the projection of the pain points of the tongue, the course of treatment was 20 days. In the comparison group, only medication was prescribed. The control group consisted of 30 relatively healthy persons at the age of 36±4.7 years without concomitant somatic diseases. Comparison of the results of the analysis of the level of pain, anxiety and depression, free radical oxidation and the activity of the serum antioxidant system after treatment in the main group and the comparison group indicates that after the complex treatment with the inclusion of the course of photoneuromodulation, the best result was obtained for reducing the level of pain, anxiety and depression, intensity of oxidative processes and increase of activity of the general antioxidant system of protection of blood serum in patients with the burning mouth syndrome.

[Influence of distal misalignment of the mandible on the development of postural pathology]. / Vliianie distal'nogo smeshcheniia nizhnei cheliusti na razvitie postural'noi patologii.

The aim of this study was to study the relationship between the distal displacement of the mandible in the temporomandibular joint (TMJ) with postural pathology. We examined 20 people from the control group (age 18-25 years) and 70 patients of the same age with temporomandibular joint dysfunction (TMJD) complicated by dentoalveolar anomalies (distal bite - 27 persons, orthognathic with anomalies of the position of individual teeth - 18, deep - 16, mesial - 4, straight - 2, open - 2, cross - 1), before and after treatment with occlusive tires. Cone beam computer tomography (CBCT) of the TMJ and photometric analysis were made to all those examined. The CBCT analysis was carried out according to the method developed by us, photometric analysis - with the help of the computer program developed by us. Thus, as a result of the study in patients with TMJD complicated by dentoalveolar anomalies were detected significant displacement of the mandible backwards and upwards, as well as according to the photometric analysis of the presence of postural disorders both in the frontal plane (the change of the head position relative to the shoulders and horizontally, impaired facial configuration in the form of an asymmetry of the arrangement of the lines of the eyes, the corners of the mouth and shoulders) and in the sagittal (the forward displacement of the head and the inclination of the vertical axis of the body forward). Treatment of patients with occlusive tires allowed to normalize the position of the lower jaw and posture.

[New method of brackets positioning for orthodontic treatment of dentoalveolar anomalies]. / Novaia metodika pozitsionirovaniia breketov pri ortodonticheskom lechenii anomalii zubocheliustnoi sistemy.

The aim of the study was to improve the accuracy of the positioning of brackets in the conduct of orthodontic treatment of the anomalies of the dentoalveolar system. The developed method of positioning the brackets assumes a temporary fixation of the wire guides in accordance with the prospective longitudinal axis of the tooth before carrying out the orthopantomography (X-Ray picture) of the teeth. According to the OPG (orthopantomography), the accuracy of determining the longitudinal axes of the teeth is estimated, and if the fixed wire guides and longitudinal axes of the teeth do not coincide, the angle is measured and corrections are made by moving their gingival part to the required value, then the impressions from the patient's jaws are taken and diagnostic plaster models having precise guidelines axis. Brackets are fixed indirectly using a standard technique by aligning the longitudinal line of the bracket with the landmark indicated on the plaster model of the jaw. The proposed method makes it possible to increase the accuracy of the positioning of brackets on the tooth surface during orthodontic treatment of the anomalies of the dentoalveolar system.

[The automation of the processing and interpreting of teleroentgenograms]. / Avtomatizatsiia obrabotki i rasshifrovki telerentgenogramm.

Demonstrates the advantages of computer preparation of teleroentgenograms (TRG) and their layout and deciphering for subsequent roentgenocephalometric analysis. Using a full-page scanner, TRG is recorded in a computer, which improves the image by transforming the histogram brightness and then superimposes this image on the contour of the initial image. The quality of layout is improved by a larger (at least two times) image on the monitor and anthropometric points marked strictly parallel to the abscissa and ordinate. All this 50 times improves the accuracy of measurements on the prepared TRG and thus increases the value of roentgenocephalometric analysis.
