Life quality is an integral part of an individual’s psychophysiological functioning in society. Its features include one’s individual health, psychological status, level of independence, social intercourse, personal beliefs formed by society and environment, as well as the individual’s capability to function in public settings in accordance with their status and to derive satisfaction from life. Subject. When rendering high-technology dental services, dental practitioners conducting a clinical examination of a patient most commonly do not consider the patient’s psychological readiness for long-term stomatological treatment and neglect their psychological constitution. Relevance. The relevance of this research stems from immaturity of medical and psychological issues of diagnosing a patient’s life quality level and correcting emotional reactions patients tend to have in the process of receiving complex dental care. The necessity of this research arose as well from clinical needs of dental practitioners. Objective. The research objective is to study life quality parameters and a patient’s attitude to dental treatment in the context of complex surgical interference. Methodology. The study employed methods of observation, questionnaire survey, and introspection of a number of the patient’s mental and psychophysiological functions during complex stomatological interference. Results. Our research showed that medical staff directly interacting with patients should have soft skills, anticipate potential risks resulting in patients’ life quality reduction, analyze such risks in a certain way, and have the opportunity and methods to solve arising questions to mutual benefit. Conclusions. For the purpose of forming life quality criteria in a patient, a dental practitioner should use not only specialized medical skills and technologies, but also skills of communicating and overcoming negative views on occurring situations in the process of conducting extensive, complex dental interference.
