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.

Introduction: This randomized clinical trial compared arch dimensional changes, dentoskeletal changes, and the rate of overbite correction in deep bite adults treated with fixed appliances and either maxillary incisor bite turbos (IBT) or canine bite turbos (CBT).
Materials And Methods: Forty-six deep bite subjects treated with fixed appliances were randomized into IBT (n = 23) and CBT (n = 23) groups. Changes in intercanine width (ICW), arch height (AH), and Little's Irregularity Index (LII) were analyzed from before treatment (T) to 3 months after aligning with 0.

Obstructive sleep apnea (OSA) is characterized by intermittent cessation of breathing during sleep due to the collapse of oropharyngeal tissues. This review examines the role of craniofacial growth in OSA and evaluates the efficacy of orthodontic and orthognathic treatments. Maxillary expansion and orthognathic surgery have demonstrated significant reductions in sleep apneas and hypopneas, although they do not consistently achieve cure levels, particularly in the presence of obesity and connective tissue disorders.

Objective: The aim of the current study was to examine possible associations between gingival thickness and other parameters, such as crown length and width, papilla height and patient's age and gender.
Overview: This cross-sectional study included 238 consecutive white Caucasian consecutive patients in all stages of orthodontic treatment (before, in-course, and after orthodontic treatment). Measurements of gingival thickness were carried out at both central mandibular incisors, mid-facially on the buccal aspect of each tooth, and 2 mm apically to the free gingival margin, with an Ultrasound device.

The aim of this comparative observational study is to evaluate and compare the size and position of the condyle among male and female patients with different skeletal patterns in the anterior-posterior dimension using cone beam computed tomography (CBCT) images. CBCT images of 120 patients, all prepared for other treatment purposes under the same conditions, were included in the study. The patients were classified into three groups-class I, class II, and class III-based on ANB angles and Wits analysis.

Introduction: Dental implants are routinely used to replace missing teeth. Therefore, the primary aim of the present study was to assess the single-unit implant failure rate over a period of seven years from 2015 to 2021, with a minimum of two years post-implant follow-up. The secondary aim was to identify the risk factors associated with implant failure using machine learning decision tree regression and Kaplan-Meier survival analyses.
