Background. According to the statistics, the incidence of dentoalveolar anomalies, as well as the frequency of orthodontic visits, is constantly growing. Objective. To analyze the efficiency of orthodontic treatment in children during the period of mixed dentition. Methods. We have performed a study on the incidence and severity of dentoalveolar anomalies of the dental status in 7-9-year-old patients vs. 15-17-year-old adolescents after the completion of occlusion. The adolescents were divided into two groups those who underwent orthodontic treatment during the mixed dentition period and those who did not. The evaluation of the childrens dental status was performed using a specialized WHO Map (2013), supplemented by the Dental Maxillofacial Anomalies section. We determined the following indices: DMF (Decayed-Missing-Filled Index), DMF-df, OHI-S, CPI, PAR, DAI, as well as the Littles irregularity index. The need in the different types of dental and orthodontic treatment was estimated, including that per one examined person in a group. Results. In the group of 7-9-year-old we have revealed a high incidence of premature teeth loss (17.0% of patients), dentoalveolar anomalies (73.9%) and their combinations (60.8%). Discussion. Orthodontic treatment during the period of mixed dentition reduces the incidence of the teeth positioning anomalies (crowding and tooth displacement) and dental arch ratio anomalies (completely eliminating the cross-bite). At the same time, early orthodontic treatment does not have a significant influence on the tooth rotation, interdental spaces, deep, open, distal, mesial occlusions and the displacement of dental arches. The severity of dentoalveolar anomalies is reduced in this case. Conclusion. Orthodontic treatment of children during the period of mixed dentition is indicated in the presence of teeth crowding and displacement, as well as in the presence of a cross-bite; concerning other types of dentoalveolar anomalies, early orthodontic treatment is justified only when the patients psychological and functional indices are reduced.

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'.

Аннотация. Актуальность. На фоне развития промышленного здравоохранения актуален анализ современной стоматологической заболеваемости у работающего населения, потребности в разных видах стоматологического лечения и протезирования. Особенно это касается стажированных работников с общесоматической патологией. Цель: анализ стоматологической заболеваемости и потребности в стоматологическом лечении у работников промышленных предприятий, находящихся на санаторном лечении. Материал и методы. Проведен анализ показателей стоматологической заболеваемости 402 работников предприятий по результатам клинико-рентгенологического обследования в санатории, на основании которых рассчитана потребность в стоматологическом лечении и его трудоемкость. Для расчета трудозатрат врача-стоматолога с учетом имеющейся потребности в стоматологическом лечении использованы показатели трудоемкости современного стоматологического лечения и профилактики, изложенные в исследовании Олесова Е.Е. Результаты. Установлено отсутствие преемственности стоматологического лечения работников по месту работы и в санатории, а также отсутствие практики санации рта работникам перед направлением в санаторий. Расчетами показана невозможность санации рта всем работникам в санаторных условиях в связи с высокой ее трудоемкостью. Заключение. Рекомендована разработка алгоритма взаимодействия врача стоматолога по месту работы и в санатории для обеспечения преемственности стоматологического лечения и концентрации усилий санаторного врача на проведение профилактических мероприятий с использованием курортных факторов. Ключевые слова: санаторий, стоматологическая заболеваемость, потребность в лечении, трудоемкость, организация.

The aim of the present study is to analyze the complexity and cost of modern methods of orthodontic treatment of children during the period of replacement bite. The study of the duration and frequency of visits to the doctor the orthodontist with the use of technology 2x4, removable plates with artificial teeth, ring spacer, plate from the front Nakonechny pad and plate valve for the language of the Twin-block appliance, mask dilara combined with the expanding apparatus, plate screw, machine screw hyrax expansion. Based on the complexity of the calculated salary orthodontist doctor, medical and other personnel. The cost of consumables at the clinical and dental stages was determined by taking into account the purchase prices and the cost of a specific manipulation by weighing or measuring. Calculated the expenditure on maintenance of workplaces of the doctor and dental technician in the calculations of the required funding early orthodontic treatment used more information about the structure and prevalence of orthodontic pathology in children in the period of the mixed occlusion. It was found that the complexity of modern orthodontic treatment during the period of replacement bite varies from 5.55 hours (spacer with a ring in case of premature loss of a temporary tooth) to 10.73 hours in the treatment of distal bite with the twin-block device. The cost of orthodontic treatment during the period of replacement bite ranges from 12.6 thousand rubles (spacer with a ring in case of premature loss of a temporary tooth) to 33.4 thousand rubles in the treatment of mesial bite using a dilyar mask in combination with an expanding apparatus. Taking into account the prevalence of dentoalveolar anomalies in children during the period of replacement bite, the necessary financial costs for orthodontic treatment per one examined child and per child with a dentoalveolar anomaly reach 30 and 40 thousand rubles, respectively.
