[The effectiveness of dentoalveolar anomalies treatment in children during early mixed dentition period]. / Éffektivnost' lecheniia zubocheliustnykh anomalii u detei v period rannego smennogo prikusa.

AIM: To analyze the effectiveness of orthodontic treatment in 7-9 years old children, dental status in children residents of Moscow was compared with 15-17 years adolescents with completed bite formation. MATERIAL AND METHODS: The adolescents were divided into two groups: those who received orthodontic treatment during the mixed dentition period and those who did not receive the treatment. A WHO survey chart was used to assess the dental status of children (WHO, 2013) with additional section 'Dentoalveolar anomalies'. DMFT and DMFT+dft, OHI-S, CPI, PAR, Little irregularity index and DAI were assessed in all groups. The need for dental and orthodontic treatment was calculated. RESULTS: Dental morbidity in Moscow children during the mixed dentition period was characterized by a high prevalence of caries (92.0%) with an intensity of 1.67±0.03, the 17.0% prevalence of premature teeth loss and dentoalveolar anomalies in 73.9% of children with a combination of anomalies in 60.8% of children. Orthodontic treatment in the mixed dentition period is associated with systematic professional control and by the age of 15 years results in two-fold reduction in the intensity of caries and periodontal disease, proper detection of poor hygiene and the lower prevalence of abnormal positioning of the teeth (crowding and misalignment of teeth) and the improvement of dental arches ratio (completely eliminating cross-bite). At the same time early orthodontic treatment has no significant effect on the prevalence of tooth rotation, interdental spaces, deep, open, distal, mesial occlusion and displacement of dental arches. CONCLUSION: Orthodontic treatment of children during the mixed dentition period is indicated in cases of crowding and displacement of teeth, as well as cross-bite; with respect to other types of dentoalveolar anomalies, early orthodontic treatment is only justified by the severe impact of dentoalveolar anomalies on psychological and functional indicators.

The cost of orthodontic treatment in children during the mixed bite period / Sebestoimost' ortodonticheskogo lecheniya u detei v period smennogo prikusa

In order to analyze the complexity and cost of methods of modern orthodontic treatment for children in the mixed bite period as well as to determine the necessary costs for eliminating dentoalveolar anomalies in primary school children taking into account the prevalence of anomalies we studied the duration and frequency of orthodontist visits during treatment using the 2x4 technique, a removable plate with artificial teeth, a ring with a spacer, a plate with a front bite pad, a plate with a shutter for the tongue, and Twin-block appliance, Dilar mask in combination with an expansion apparatus, plates with a screw, appliance with a hyrax expansion screw. Based on the complexity the salary of the orthodontist and other personnel, the costs of maintaining the doctor's workplace and the dental technician are calculated. The cost of consumables at the clinical and dental stages was determined considering the purchase prices and the cost of a specific manipulation by weighing or measuring. When calculating the necessary funding for early orthodontic treatment modern data on the prevalence and structure of orthodontic pathology in children during the mixed bite period were used. It was found that the complexity of modern orthodontic treatment during the mixed bite period varies from 5.55 hours (spacer with a ring for premature loss of a temporary tooth) to 10.73 hours in the treatment of a distal bite with a twin-block device. The cost of orthodontic treatment in mixed bite varies from 12.6 thousand rubles (a spacer with a ring for premature loss of a temporary tooth) to 33.4 thousand rubles for the treatment of a mesial bite using a Dilar mask in combination with an expanding device. Given the prevalence of dentoalveolar anomalies in children during mixed bite period, the necessary financial costs for orthodontic treatment per child examined should be at least 30 thousand rubles, and at least 40 thousand rubles for a child with a dentoalveolar anomaly.

[Guidelines for dental care in departmental sanatoriums for workers with hazardous working conditions]. / Obosnovanie reglamenta okazaniia v vedomstvennykh sanatoriiakh stomatologicheskoi pomoshchi rabotnikam proizvodstv s opasnymi usloviiami truda.

The aim of the study were protocols of dental care in departmental sanatoriums for workers with hazardous working conditions (HWC). Provided dental care and staff features were analyzed in 10 sanatoriums basing on their annual 2016 reports. In Central Clinical Sanatorium 'Malakhovka' dental care need was assessed in 402 males (mean age 39.2±1.2 years) with HWC. The study results were used for guidelines of departmental 'Dental care in resort rehabilitation of workers with hazardous working conditions'.
