Introduction. Timely and reasonable provision of combined orthodontic and orthognathic care to persons with combined dental anomalies determines the effectiveness of treatment and the quality of life of this category of patients. The treatment of patients depends on social, economic and demographic factors. Objective: to determine the specifics of seeking orthodontic care for people with combined dental anomalies, taking into account the socio-demographic factors of this contingent. Material and methods. An in-person survey was conducted of 159 patients with combined dental anomalies who are being treated in the Department of Maxillofacial and plastic surgery of the Russian University of Medicine. The average age of the surveyed patients was 27.2±5.44 years [18;39]. Among the surveyed males, n=85, 53.5%, and residents of Moscow, n=73, 45.9%. The questionnaire was compiled by the authors of the article, adjusted by expert assessment and validated in a pilot survey of 19 patients with combined dentoalveolar anomaly. The questionnaire contained questions about socio-demographic characteristics and the timing and results of the first and subsequent requests for orthodontic care, the reasons for rejecting orthodontic treatment. The SPSS program evaluates the normality of the age distribution, frequency analysis of all variables in general and in selected socio-demographic groups; calculation of the Mann-Whitney and Kraskel-Walliss U criterion for comparing averages in two or more groups; calculation of χ2 in the conjugacy tables comparing the frequency of a trait in groups; Spearman's correlation analysis of the respondent's age and the age of the first appeal. In all calculations, the threshold value of the error level (p) is 0.05. Results: 134 (84.3%) respondents with combined dental anomalies had previously sought orthodontic care. The average age of the first treatment is 14.4±2.59 years [10;24]. The age of the first appeal of persons of different sexes (p=0.220) living in Moscow and the regions (0.179), different activity on social networks (p= 0.417) is the same. The difference in the age of the first treatment between the three age groups of 18-24 years (13.1±1.64 years), 25-31 years (14.4±2.16 years), 32-39 years (16.6±3.20 years) was significant (р≤0,001). 101 respondents (75.4%) refused the treatment recommended at the first treatment: 35 (26.1%) due to lack of financial resources, 22 (16.4%) waiting time for help, 37 (26.7%) unavailability of assistance at the place of residence, 7 (5.2%) fear. The proportion of those who refused the recommended treatment at the first treatment is significantly (p=0.028) higher among residents of the regions (83.1%) than among Muscovites (66.7%). Patients who are active users of social networks (30.8%) were more likely (p=0.047) to refuse recommended orthodontic treatment due to the length of waiting than non-active users (21.3%) or patients who do not have a social media account (4.8%). Discussion. The vast majority of adult patients with dental anomalies are not the first to seek orthodontic care. The first treatment of such patients occurs in adolescence, while there is a relationship between the age of the first treatment and the age of the patients. Earlier referrals may be influenced by the increasing awareness of orthodontic care among each younger generation of patients and their parents. The rejuvenation of requests for orthodontic care is not associated with an improvement in its accessibility, as one third of patients refused treatment due to lack of personal financial resources, another third - due to the unavailability of recommended medical care at their place of residence, and one in five – due to a long wait for free care. Conclusions: The age of first seeking orthodontic care for people with dental anomalies decreases in each subsequent generation. The proportion of refusals from orthodontic care at the first treatment is extremely high. The main reasons for rejecting orthodontic care at the first request are the unavailability of assistance at the place of residence and lack of funds. The availability of orthodontic care for people with dental anomalies is lower in non-Moscow regions.
