Features of higher nervous activity in young people with different states of periodontium
Summary. The issue of the influence of individual psychophysiological characteristics of a person on the periodontal tissues condition remains open to this day. In particular, the relationships between the features of higher nervous activity and the development of periodontal pathology in young people have been little studied.
The aim of the study – to learn the individual features of sensory and motor response when performing tasks of varying degrees of complexity and basic properties of nerve processes in young people with a different state of periodontal tissues.
Materials and Methods. The study groups included 109 students of the I and II years of study (18–23 years old) of I. Horbachevsky Ternopil National Medical University. 61 people with the presence of inflammatory periodontal diseases were selected to the main group, and 48 persons without this pathology – to the control group. Assessment of the higher nervous activity features was conducted by M. V. Makarenko express methods using the device and computer system «Diagnost-1M», developed by M. V. Makarenko in co-authoring with V. S. Lyzohub. The work was carried out in two stages: the study of individual differences in sensory and motor response in solving problems of varying degrees of complexity and the study of the basic properties of nerve processes (functional mobility and strength).
Results and Discussion. Significantly lower values of latent periods of simple visual and motor reactions were revealed in subjects with inflammatory periodontal diseases, compared with the control group. ((262.128±73.496) ms against (308.527±101.443) ms, p=0.0067). Also, there were significantly lower latent periods of the complex visual and motor reaction with two of three signals choice in the surveyed of the main group than those of the periodontologically healthy students ((418.876±60.973) ms and (449.709±65.962) ms, respectively, p=0,0139).
Conclusions. Consequently, students with inflammatory lesions of periodontium have a higher level of excitability of the central nervous system.
