Introduction. The proportion of patients with jaw abnormalities is 35%-78% among the population. An analysis of the literature does not allow us to conclude about the influence of gender and age on the treatment of persons with combined jaw deformities for orthodontic care. Although epidemiological data on patients with combined jaw deformities are necessary to better understand the pathology and determine measures for timely orthodontic treatment. The aim of the study was to determine the influence of age and gender on providing of orthodontic treatment for persons with combined jaw deformities. Materials and methods. A retrospective analysis of 360 dental patient records was carried out. The base of the study was the State Medical Institution of the Moscow region "Balashikha Dental Clinic No. 1". The selection of patient’s cards was carried out according to the criterion of "presence of combined jaw deformity". The patient’s cards with anomalies and malocclusion deformities of a dental alveolar nature, cleft lip and (or) palate were excluded from the sample. Information about the age, gender of the patient, the primary or repeated treatment, the presence or absence of previously performed orthodontic treatment, and the type of orthodontic treatment were recorded from the cards. Static processing is performed in the SPSS program, version 23 (IBM). Frequency analysis, assessment of the normality of the distribution, determination of the median, median test, calculation of the Fisher criterion was performed. Results. In patients of different sexes with combined jaw deformity, the age of the first and follow-up visit for orthodontic treatment does not significantly differ, p= 0.951, respectively. The age of the first and follow-up visit for orthodontic treatment of persons with combined jaw deformity in men (Me=27.0 vs Me=21.0) and women (Me=27.0 vs Me=21.0) does not significantly differ, p≥0.05. The proportion of previously treated patients is the same among men and women (φemp=0.198). The proportion of return visits is higher among patients 18-24 years old than among 25-31 years old (φemp=7,394) and among people 32-39 years old (φemp=4,756). The proportion of previously treated patients is lower among patients aged 25-31 years than among patients aged 18-24 years (φemp=2,213) Discussion. Perhaps the reason for the lack of referral of a third of patients with combined jaw deformities to orthodontists by outpatients' clinic dentists is the insufficient level of qualification of the latter in the management of this category of patients. It is likely that patients with combined jaw deformities seek orthodontic care in our country earlier than in other countries. It is obvious that the higher medical activity of the younger generation is associated with an improvement in the availability of orthodontic care in recent years. Conclusions. Gender does not affect the timing of seeking orthodontic care for people with combined jaw deformity. Medical activity regarding orthodontic care is higher in the buzzer generation than in the millennial generation.
