The article presents the data of a complex dental and neurophysiological examination of young people with parafunctional activity of the masticatory muscles (bruxism). The effectiveness of stress-protective lateral heterosuggestion technique in the etiological and pathogenetic correction of bruxism and the possibility of its use in dental practice have been proven.

Purpose of the study. To establish the relationship between neurophysiological status and the level of efficiency in young people with bruxism.Materials and methods. Two groups of 64 and 53 subjects (males and females) aged 20–35 years old with bruxism and non-bruxers were formed according to questionnaire results and physical examination. The level of efficiency was assessed by the results of sensorimotor tracking of a moving object (the ‘Smile’ model). Spectral analysis was performed for evaluation of the baseline electroencephalograms. Microsoft Excel and Statistica 10.0 programs were used for statistical data processing.Results. The level of efficiency was statistically significantly lower in the hardest test of Smile model among the individuals with bruxism (p < 0.05). The bruxers also demonstrated a significantly lower dominant frequency and maximum amplitude of alpha-rhythm (p < 0.05), and significantly higher dominant frequency of beta2 rhythm (p < 0.05). The dominant frequency and the maximum amplitude of the alpha-rhythm are parameters corresponding to significant coefficients of the regression analysis. A negative relationship was found between the degree of error during sensorimotor tracking and the frequency and amplitude of alpha-rhythm.Conclusion. Regression models present the relationship between the level of efficiency and the alpha-rhythm severity. The regression equations make it possible to determine the functional state of the subject using an electroencephalogram.

With the use of Cosinor method, a modeling of oral liquid average daily secretion rate was carried out. A definite temporary structure of oral liquid parameters modification in the range of circadian rhythm was detected.
The present study is devoted to biorhythmical organization of a human oral liquid parameter such as acid-base balance. A definite temporary structure of oral liquid pН changes in the range of circadian rhythm was detected with the use of Cosinor method.
