Exploring the associations of sleep bruxism and obstructive sleep apnea with migraine among patients with temporomandibular disorder: A polysomnographic study

Sleep bruxism may not be associated with migraine among patients with TMD; however, mixed bruxism episodes were more frequent in the migraine group. The increased duration of SB episodes in patients with migraine may suggest the common background of these conditions. OSA is also not associated with migraine; however, MwoA might increase the odds of OSA. There is a need to further explore sleep disturbances and migraine, especially in groups with their increased prevalence, such as patients with TMD.
