Relationship between pain, quality of sleep, sleep bruxism and patients' personality among individuals with reported orofacial pain.

The study aimed to determine the relationship between personality traits, orofacial pain (OFP), and headache. Eligible patients underwent one-night videopolysomnography and completed a series of validated questionnaires assessing sleep quality (ISS- Insomnia Severity Scale, PSQI- Pittsburgh Sleep Quality Index, ESS- Epworth Sleepiness Scale), pain intensity (McGill Pain questionnaire, GCPS- Graded Chronic Pain Scale, HIT-6- Headache Impact Test-6, MIDAS- Migraine Disability Assessment, TMD pain screener- Temporomandibular Disorder pain screener), psychoemotional state (KPS- Sense of Stress Questionnaire, PHQ-9 - Patient Health Questionnaire-9, BDI- Beck Depression Inventory, BAI- Beck Anxiety Index, PSS-10- Perceived Stress Scale-10, GAD-7- Generalized Anxiety Disorder-7), personality traits (IPIP-BFM-20 -International Personality Item Pool- Big Five Markers- 20). Patients who exhibited nervousness and hypersensitivity reported higher perceived pain and greater negative impacts on work and daily activities (p = 0,000). Furthermore, a statistically significant relationship was found between subjective sleep quality and emotional stability scales (p = 0,001 for PSQI, p = 0,000 for ISI, p = 0,001 for ESS). However, no such relationship was observed for objective sleep quality, as measured by polysomnography (p > 0,05). The correlation between the emotional stability scale and each of the questionnaires used to examine anxiety, depression, and stress was very strong and corresponded to p = 0.000.
