Abstract. Due to the presence of war in Ukraine, children have an increased level of anxiety. Оn the other hand it is a difficult stage in life of young people who lose the ability to communicate offline, especially during distance learning. It is difficult for children to adapt to the constant stay at home, to communicate with classmates and friends online, to adapt to the new rhythm of life and the dynamics of learning.. The modern educational system has changed so much in the last two years that the student must constantly adapt to new learning platforms and innovations. And the inability to clearly see and do laboratory classes in many subjects, self-study, even physical education classes leads to chronic stress.
 The study of the problem of anxiety and social emotional chronic stress on the formation of disorders on the part of the maxillofacial system is relevant. Stress is becoming an increasingly global problem, especially among children, because it negatively affects their lives and health, the progression of bad habits, and in turn, disorders of the dental system. Therefore, it is important to study the problem of social emotional chronic stress in the educational activities of students in terms of distance learning and its impact on the formation of disorders of the dental system.
 To reduce the impact of stressors, children use oral habits: sucking fingers, biting nails, pencils or pens, sitting in front of a monitor with his mouth open, despite a positive breath test, in the same position resting his head on his hands, causing chronic injury in this area. According to many studies, this may be the result of a person's adaptation to existing chronic stress.
 The article is based on a quantitative study conducted among school-aged patients with oral by means of a secret questionnaire. The level of anxiety was determined using the STAI (State-TrateAnxiety-Inventory) scale. We determined personal and situational anxiety. High levels of anxiety turn into stress, which is becoming a more global problem, especially among children. It has a negative impact on their life and health, on the progression of oral habits and, in turn, on the appearance of acquired dental and maxillomandibular anomalies. Therefore, it is relevant to study the problem of anxiety in children, social emotional chronic stress on the appearance of oral habits and, as a result, on the development of maxillomandibular anomalies.
 The article presents the results of an anonymous survey of 120 patients with existing maxillomandibular anomalies, which includes the periods of anxiety, various stress factors, the progression of chronic oral habits, and their influence on the development of maxillomandibular anomalies. Our results of a secret survey indicate the state of chronic stress of students, their being in a state of social stress due to new living conditions in the war period in Ukrine; frequent changes between periods of live communication and distance learning; psychological problems in the family; emotional relief during the habit. Due to the fact that children live in conditions of chronic stress, they lose motivation to learn. They do not get pleasure from it, but in turn seek help in habits that, according to our patients, help reduce the impact of stress on quality of life and their own emotional state. The results of the study explain the formation of adaptive responses of the body to the stress and confirm the relationship between chronic oral habits in children under influence of anxiety and social stress.
