Dependence of bruxism manifestations on human temperament

Aim – to quantify the influence of neurodynamic features of temperament (according to Eysenck) on clinical and electromyographic markers of bruxism. Material and methods. This study was conducted in two stages. At the first stage, a questionnaire based on the theory of Hans Eysenck was made to determine temperament. 200 people aged from 18 to 60 years took part in the survey and, depending on the test results, were further categorized into 4 groups: cholerics, sanguines, phlegmatics and melancholics. At the second stage we evaluated the manifestations of bruxism in patients in the formed groups. The following methods were used to diagnose bruxism: questioning of participants about the presence of bruxism symptoms; objective assessment of the dento-mandibular system using dental examination and electromyography of temporal and masseter muscles. Results. The results of the study showed that the manifestations of bruxism vary depending on the type of temperament. In the choleric group, 72% of participants suffering from bruxism were identified, in the sanguine group, 54%, phlegmatic, 38%, and melancholic, 60%, and the percentage of complications in these groups was 40%, 20%, 10% and 25%, respectively. Conclusion. Understanding individual patient characteristics can help orthopedic dentists develop more effective strategies for the treatment and prevention of this condition.
