One of the main competencies of the future doctor is developed stress resistance. High level of stress is characteristic of student’s life, but at the same time, it is favourable for opportunities related to the development of viable strategies and attitudes of the individual. It necessitates the study of stress factors of students and ways of its development. Objective. The objective of the article is theoretical and experimental study of psychological factors of stress resistance in medical and dental faculties’ students when forming their professional readiness. The sample included 104 people aged 18 to 20 years, who were 2 to 4 course students of medical and dental faculties of Poltava State Medical University. Methods and materials. The following methods were used in the empirical study: «S. Muddy's stress test», adapted by DA Leontiev and EI Rasskazova, «Test of meaningful life orientations (MLO)» by D. Leontiev and «Boston stress test». The study was conducted in November 2021 remotely, using Google questionnaires. Statistical processing of research results was carried out using Microsoft Excel Office 2010. The statistical significance of difference between groups was determined using the Student's t-test. Results. As a result of the study, some differences in the features of stress resistance between students of dental and medical faculties were revealed. Students of the medical faculty had a higher level of stress resistance. They were more focused on mastering the profession and professional activity and had higher risk-taking rates than dental faculty students. There were also differences in the value-semantic sphere: existential attitudes were more common among medical students and utilitarian attitudes ­– among dentists. Based on the obtained results, we conducted training on stress resistance in order to increase the level of stress resistance, which should be considered a way to respond to stressful situations.

Резюме. В основі генералізованого пародонтиту лежить запально-дистрофічний процес, який виникає в організмі під впливом патогенних факторів. Організм людини перебуває під постійним впливом різноманітних чинників зовнішньої та внутрішньої природи, які взаємодіють між собою, а реакція організму на їх вплив може бути різноманітна. Визначається вона рядом моментів, у тому числі й природою патогенного фактора. Мета дослідження – оцінити вплив патогенних факторів на стан тканин пародонта у пацієнтів із генералізованим пародонтитом. Матеріали і методи. Для досягнення поставленої мети проведено обстеження 230 осіб віком від 25 до 65 років, 204 з яких мали клінічні симптоми хронічного генералізованого пародонтиту (ХГП) (три дослідні групи із I, II, III ступенями тяжкості), 26 – здоровий пародонт (контрольна група). Результати досліджень та їх обговорення. Для оцінки впливу ряду патогенних факторів на розвиток генералізованого пародонтиту ми провели аналіз зв’язків впливу можливих хвороботворних чинників на тканини пародонта. Виконане всебічне обстеження пацієнтів із генералізованим пародонтитом та здоровими яснами дозволило систематизувати наслідки дії та вплив місцевих і загальних патогенних чинників, які  залежно від стану адаптаційних можливостей організму можуть призвести до розвитку та обтяження патологічного процесу в тканинах пародонта. Висновки. Результати проведеного місцевого обстеження (щелепно-лицевої ділянки) пацієнтів із ХГП та осіб із здоровими тканинами пародонта свідчать про наявність зв’язків дії місцевих хвороботворних факторів на розвиток хронічного генералізованого пародонтиту. Для ефективного лікування пацієнтів із ХГП та досягнення ремісії і довготривалої стабілізації запально-дистрофічного процесу в тканинах пародонта важливим є персоналізований підхід із урахуванням як місцевих, так і загальних хвороботворних факторів та індивідуальних особливостей організму.

Connection of the publication with planned research works.The study is a fragment of the research work of the Department of Therapeutic Dentistry of the Poltava State Medical University, «Development of pathogenetic prevention of pathological changes in the oral cavity of people with internal diseases»; state registration number 0121U108263.Introduction.According to WHO (2019), periodontal disease is diagnosed in 65-98% of patients aged 35 to 44. The multifactorial etiopathogenetic model of inflammatory and inflammatory-dystrophic lesions of periodontal tissues explains the complex approach to their treatment, which involves prescribing a significant number of pharmacotherapeutic drugs [1].The source of antimicrobial agents in treating periodontal diseases can be extracted from medicinal plants. Their peculiarity is that their biologically active substances are in a particular ratio, contributing to the optimal effect on the human body. Some constituent components of herbal preparations are similar to physiologically active substances of the body (hormones, vitamins, enzymes, etc.). Due to this, they are more actively involved in the biochemical processes of the human body than synthetic ones. Unlike traditional antibacterial drugs, most antibiotics of plant origin, in addition to antimicrobial action, have a pronounced positive effect on the microorganism [2].The main advantage of herbal remedies is the optimal composition due to the content of various biologically active substances, alkaloids, flavonoids, glycycoumarin, lycocoumarin, etc. [3,4].Among the advantages of plant-based drugs are the absence of adverse reactions, the possibility of longterm use, compatibility with other medications, as well as with each other; it is possible to use it at home, without the presence of special equipment, trust in the part

Local injectable anesthesia is widely used in modern dentistry. First of all, the purpose of anesthesia in the practice of the doctor is to relieve the patient’s emotional stress and eliminate pain during the procedure. According to the classical position of N. E. Vvedensky, local anesthetics affect the functional state of the nerve, changing its conductivity and excitability. With the help of questionnaires we conducted a survey of 65 patients aged 18 to 75 years who sought medical help at the regional dental center in Poltava. The results of a questionnaire of doctors on the use of local anesthetics in dental practice were also analyzed. With the help of laboratory methods of examination of oral fluid, a decrease in the rate of salivation, saliva pH, leukocyte migration rate was determined. The purpose of the survey was to identify the frequency of manifestations of various allergic reactions to drugs in patients. All patients were systematized by age and comorbidities, which further affected their distribution. The distribution of patients by risk groups (allergy history) allowed to assess the prevalence of allergic diseases depending on age and sex. Particular attention was paid to elderly and senile patients, as their condition is characterized by a decrease in compensatory and adaptive capabilities. Patients with somatic pathology and persons with multiple foci of chronic odontogenic infection should be classified as at risk for the development of allergic reactions to local anesthetics, which should be taken into account when performing local injection anesthesia on an outpatient basis. It should be remembered that concomitant pathology affects the choice of anesthetic and can determine the development of toxic reactions during local injection anesthesia in the head and neck. This category of patients requires dentists to take a more responsible approach to collecting medical history and taking preventive measures to prevent the development of allergic and toxic reactions to local anesthetics.
