Recurrent mumps or chronic bilateral enlargement of the parotid salivary glands may be the first symptom of Sjogren's disease, which is recommended to extend the examination in order to identify other, sometimes latent signs of the disease.This article describes a case report of the patient with mandibular retrognathia, class II malocclusion, constriction and deformation of dental arches and bimaxillary protrusion. Due to the patient's refuse to undergo the orthognathic surgery, after diagnostic, it was decided to carry out the orthodontic dentoalveolar compensation. click here The combined use of the functional fixed telescopic appliance (FFTA), bracket system and orthodontic miniscrews made it possible to effectively normalize the mandibular position, achieve orthognathic occlusion, eliminate bimaxillary protrusion and improve the face profile. This method significantly reduced invasiveness and time of orthodontic treatment.The article reports a patient with an unusually large synovial chondromatosis of the temporomandibular joint. In this clinical case, the extremely rare sizes of chondral bodies are given, because of which it was required to expand the standard access to the TMJ with the isolation of the trunk and branches of the facial nerve.
The aim of the present paper was to observe the main features of the autofluorescence emission of the oral epithelial carcinomas.
The study included four patients aged 38-61 years with the oral epithelial carcinomas located at a cheek, a floor of the mouth, a bottom lip. All the diagnoses were later confirmed histologically. The oral cavity was inspected traditionally and then using autofluorescence visualization. For autofluorescence emission excitation we used the home-made LED-based device emitting near 400 nm.
The tissue autofluorescence was visualized in the broad and narrow spectral bands. In comparison with the healthy mucosa the pathological lesions showed the large losses of the green autofluorescence emissions ("dark sport effect") which have been visualized at both spectral bands. The visualization in the broad spectral band allowed to reveal that three lesions had the local sites of red fluorescence of the endogenous porphyrins traditionally connected with the local inflammation.
Autofluorescence stomatoscopy is not only important but also mandatory for oncological screening and should be widely used as the additional method of oral mucosa examination in the common dental practice.

The aim of the study is to assess the status of dental care for contagious patients in hospitals using the example of the Volga Federal District.
The resource allocation of dental care for contagious patients in 313 hospitals of 14 subjects of the Volga Federal District was investigated.
It was found that in 86.1% of multidisciplinary hospitals of the Volga Federal District, where infectious beds and dental offices are present, dental care for patients with infectious diseases accompanied by lesions of the oral mucosa is not provided. The bed capacity of 92.9% of infectious hospitals in the Volga Federal District is less than 400 beds, which does not allow to deploy dental offices on their basis.
An important condition for improving the quality of medical care to patients of infectious hospitals and infectious diseases departments of multidisciplinary hospitals is the availability of dental offices and dental doctors, which will ensure timely diagnosis, treatment and prevention of lesions of the oral mucosa in diseases of infectious genesis.

The purpose of the study is to conduct a comparative analysis of the cleaning effectiveness of toothbrushes of various types in children aged 6-15 years after a single tooth brushing.
A parallel, randomized, open clinical trial was conducted aimed at evaluating the effectiveness of toothbrushes of various types in children aged 6-15 years. The study involved 180 children of both sexes aged 6-15 years, who were divided into 3 age categories 6-8 years (
=60), 9-11 years (
=60) and 12-15 years (
=60). In each age category, 3 groups of 20 people were randomly formed who received toothbrushes of different types groups I, IV and VII - a manual brush with a multi-level brush field, groups II, V and VIII - a manual brush with an even brush field, groups III, VI, IX - an electric brush with the technology of reciprocating and pulsating movements. After the dental examination, the children were taught the standard method of brushing their teeth. The cleaning efficiency of toothbrushes was evaluated using the hyge hygienic education of children of this age, it is necessary to pay more attention to the formation of the correct technique of brushing teeth with the help of manual brushes corresponding to age characteristics.
An electric toothbrush is the most effective means of oral hygiene in children. In children aged 6-8 years, a high cleansing effect was achieved with a manual brush having a multi-level brush field. In the hygienic education of children of this age, it is necessary to pay more attention to the formation of the correct technique of brushing teeth with the help of manual brushes corresponding to age characteristics.
Was to reveal possible correlation between child's birth weight, BMI at examination, dental caries prevalence and intensity.
The study comprised 220 healthy children aged 3-6 born mature and attending nursery schools in Khimky city (Moscow region, Russia). Data on birth weight were extracted from a healthcare reports database, current height and weight were measured and BMI was calculated and interpreted according to WHO criteria. Calibrated pediatric dentists performed oral examination registering the dmft index.
Children suffering from dental caries at the age of 3-6, have lower birth weight and struggle to put it on later in life. This results in higher proportion of children with underweight. Among children with caries 69.2% had BMI lower than 15
percentile, and 28.3% had very low IMT (lower than 5
percentile) vs 5.6% in the group without caries (
<0.05). The mechanisms and the direction of this correlation are unclear.
There is a necessity for further investigations on the role of various factors associated with body weight and alimentary status in the development of the early childhood caries.

Hypophosphatemic rickets (HPPR) and hypophosphatasia (HPP) are hereditary pathologies accompanied by phosphorus metabolism problems and rickets deformities of the skeleton. Periodontal diseases, their diagnostic methods and factors affecting the progress of periodontal tissue damage are the least studied among the dental manifestations of HPPR and HPP.
The aim of present cohort study was evaluation of periodontal tissue status in adolescents with HPPR and HPP.
A dental examination of 20 adolescents aged 12 to 18 years with genetically and biochemically confirmed hereditary rickets-like diseases (E83.3 Disorders of phosphorus metabolism and phosphatases hypophosphatemic rickets (HPPR) and hypophosphatasia (HPP)) was performed at the Pediatric Dentistry Department of Moscow State University of Medicine and Dentistry. In the present study clinical examination and cone-beam computed tomography (CBCT) data of patients were analyzed.
According to the clinical examination data, a strong direct correlation was found between patient's age and the periodontal diseases severity (correlation coefficient
=0.87) in the study group. CBCT revealed the significant alveolar bone hypomineralization in adolescents with HPPR and HPP in comparison to control group (
<0.05). According to the measurement results obtained a strong inverse correlation between alveolar bone mineral density and alveolar bone reduction (correlation coefficient
= -0.74) in adolescents with hereditary rickets-like diseases was revealed.
The diagnostic options of CBCT allow to begin comprehensive dental treatment of patients with HPPR and HPP at an early stage of periodontal disease preventing further development of pathology.

The objectivewas to study the effect of changing the anglconvergence of the abutment walls, depending on their height, as well as the number of supports, on the accuracy of fitting metal-ceramic prostheses to the abutments.
It was studied 72 constructions prostheses on single abutments with abutment heights from 3 mm to 9 mm with an increase in height of 2 mm, an angle of convergence of the abutment walls from 0° to 10° with an increase in convergence of 2° in the amount of 24 prostheses; 24 framework designs supported by two abutments, with the same parameters (height and angle of inclination of the abutment walls) and prostheses supported by three abutments in the amount of 24 designs. The abutments were milled from a titanium alloy Ti-6Al-4V, and the prostheses were cast from a cobalt-chrome alloy. During fabrication of the prostheses, a compensation varnish was applied to the respective abutments to create a gap between the framework and the abutment for a 50 μm thick cement film. The crown prosthesesre.
The aim of the study was to develop a technique for 3D analysis of the occlusal balance of teeth.
The development was carried out on the basis of the Avantis 3D software («Avantis 3D» LLC, Russia) using teeth scans of 50 subjects with Class I and II (Division 1) malocclusion and different degree of tooth wear. The algorithm and formulas for calculating the balance of symmetry and antero-posterior occlusal balance are presented. The essential features of the technique and the interpretation of the obtained indicators are explained on different clinical cases. Statistical analysis of the results of measuring occlusal balance of patients with different degree of teeth wear and malocclusion is presented.
It is determined that the balance of common contacts is more important than the balance of direct contacts.
Alignment of teeth without noticeable wear provides a better occlusal balance then before. The occlusal balance of worn teeth after alignment may be not good and require selective grinding or restoration of their occlusal surfaces.
