Description
Summary:Aims: To explore pathophysiological and psychosomatic mechanisms of sleep bruxism (SB) and its impact on sleep, quality of life (QoL), mental health and somatic functioning. Methods: 71 young individuals with sleep bruxism and no other important medical conditions underwent sleep evaluation including full overnight video-polysomnography (video-PSG), dental examination, laboratory tests and filled a battery of questionnaires assessing sleep quality, mental state, stress exposure, quality of life and somatic symptoms. Results: The enrolled patients were 35 years old (SD 11). In PSG evaluation we confirmed moderate SB in 24 (33,8%) and severe SB in 31 (43,7%) participants. In the SB group, 14 (25,5%) met criteria of Obstructive Sleep Apnea (OSA); RR of OSA development in SB group was 1,45. In the SB group, 20 (36,4%) reported possible insomnia, 29 (52,7%) excessive daytime sleepiness, 16 (29%) had positive score in Beck Depression Inventory, 40 (72,7%) reported poor sleep quality and 28 (50,9%) scored positively in Perceived Stress Scale 10. Severe SB was related to higher urine concentration of 17-hydroxycorticosteroids (p=0,033), higher oxygen desaturation index (ODI) (p=0,042), longer Nl and REM sleep (p=0,034 and p=0,007, respectively), shorter N3 sleep (p=0,015), lower minimal blood oxygen saturation (p=0,04) and more arousals (p=0,0001). Lower subjective QoL in somatic and psychological domains was related mostly to poor sleep quality (p
