Exploring the Complex Relationship Between Primary Headache Types and Bruxism: Patterns, Mechanisms, and Implications

Objective: The present study aims to explore the relationship between primary headache types and bruxism and determine how these two conditions may affect each other. Material and Methods: A total of 97 cases who applied to the Neurology Polyclinic of our hospital during 01.07.2023-01.08.2023 were included in the study. A comprehensive questionnaire was applied to the participants. The diagnosis of headache was established based on the International Classification of Headache Disorders criteria; the American Academy of Sleep Medicine criteria were used for the diagnosis of sleep bruxism and the Research Diagnostic Criteria for Temporomandibular Disorders were employed for the diagnosis of awake bruxism. Results: Nineteen (19.6%) of the participants were male and 78 (80.4%) were female. Tension-type headache (TTH) was reported by 22 participants (22.7%), 30 participants had migraine-type headache (30.9%), and 45 participants (46.4%) comprised the healthy control group. Sleep bruxism was observed in 29 patients (29.9%), while 11 patients (11.3%) were diagnosed with awake bruxism. Higher rates of sleep bruxism and awake bruxism were seen in patients in the TTH group compared to those in the migraine group and the healthy control group (p
