The aim of the current study was to evaluate the prevalence of psychopathological symptoms in patients who self-reported different forms of bruxism by means of clinical and anamnestic diagnostic criteria. Eighty-five participants were divided into four groups as sleep bruxers (12), awake bruxers (24), sleep-awake bruxers (33), and non-bruxers (16). A self-report symptom inventory questionnaire (Symptom Checklist-90-Revised (SCL-90-R)) was filled out by all groups to determine their psychopathological symptoms. As regards mean psychopathological scores, patients with sleep-awake bruxism endorsed the highest scores. In addition, patients with awake bruxism showed higher scores than patients with sleep bruxism and non-bruxism in most SCL-90-R subscales. Kruskal-Wallis test revealed significant differences between groups in any of the SCL-90-R subscales, except for the psychoticism subscale. Mann-Whitney test followed by Bonferroni's test correction between non-bruxer and sleep-awake bruxer groups revealed significant differences in depression, anxiety, hostility, phobic anxiety, paranoid ideation, global severity index, positive symptom distress index, and positive symptom total in all SCL-90-R subscales. Statistical analysis of our study showed that differences between groups were significant in all SCL-90-R subscales except for the psychoticism subscale. Better distinction of bruxism forms may help to develop new treatment strategies for bruxism disorder.
