Correlation between bruxism and socio-demographic factors in Lithuania, quality of sleep and symptoms of anxiety and depressive

Relevance of the problem and aim of the work. Students from the university can experience too much stress because of unsatisfactory academic results, personal emotional problems as well as the permanent academic activity can cause irregular sleep / wake patterns and might have the effect for poor quality of sleep. Emotional factors such as anxiety and depression cause and anchor the gnashing of the teeth resulting in increased muscle tension. Bruxism is defined as the repetitive activity of jaw muscles as well as clench and friction of the teeth. Usually the night bruxism affects around 13% of adults. Aim of the work is to find out the relationship between socio-demographic factors, anxiety, depressive symptoms, sleep quality and bruxism. Material and methods. The study was performed in Kaunas, Lithuanian University of Health Sciences Faculties of Medicine and Dentistry. There were interviewed Ist and Vth year students from Faculty of Dentistry as well as the Ist and VIth year students from the Faculty of Medicine. Subjects received four different self-reported questionnaires. Statistical analysis was performed with data collection and analysis program SPSS 17.0 (Statistical Package for Social Science for Windows 13). Results. The results showed that the Pittsburgh sleep quality index and incidence of bruxism is statistically significant, direct, low-strength connection r = 0.176, p = 0.001. Among the severity of the symptoms of anxiety and depression and worsening incidence of bruxism is statistically weak bond strength as well as Ist and VIth year medical students experience anxiety. Anxiety and depression symptom score difference in these groups is 2,043. This difference is statistically significant (p = 0.041). Conclusion. The relationship between socio-demographic factors and the incidence of bruxism is statistically significantly associated with the study program, course, age and income per month. Fifth-year dental students more often suffer from bruxism (43.8 %) compared with the Ist and VIth year medical students and first-year dental students. Students whose income is 300 euros and more, is suffering from bruxism - 35.8 % those whose revenues — 100 - 299 euros - 25.2 % and 17.6 % up to euros 100. A statistically significant association between anxiety, depressive symptoms and bruxism is established between Ist and VIth year medical students (p = 0.041). The connection between sleep quality and bruxism is statistically significant only between Ist and VIth year medical students
