Bruxism, Pelvic Pain, Erectile Dysfunction, and Anxiety in Young Adult Men

Bruxism has been linked with stress, anxiety, autonomic nervous system dysregulation, and central sensitization processes. These mechanisms may also play a role in the development and maintenance of chronic pain conditions beyond the orofacial region.

Pelvic pain and sexual dysfunction in men, including erectile dysfunction, are complex conditions with multifactorial etiologies involving musculoskeletal, neurological, vascular, and psychosocial factors. Increasing evidence suggests that pelvic floor muscle overactivity, stress-related autonomic responses, and psychological distress may contribute to pelvic pain syndromes and sexual dysfunction. Anxiety, in particular, has been identified as an important factor influencing both pelvic floor muscle tension and erectile function.

Given that bruxism is associated with muscle hyperactivity, stress responses, and psychological factors, it is plausible that individuals with bruxism may also experience symptoms related to pelvic floor dysfunction. However, the potential relationship between bruxism and male pelvic health outcomes, such as pelvic pain and erectile dysfunction, has not been sufficiently investigated in the literature. Understanding whether bruxism is associated with pelvic symptoms may provide insight into shared neuromuscular or biopsychosocial mechanisms.

The primary aim of this cross-sectional study is to investigate the association between bruxism and pelvic pain in young adult men. Secondary aims include examining the relationship between bruxism and erectile dysfunction as well as anxiety levels. Participants will be young adult men recruited from the general population. Bruxism status will be assessed using validated self-report measures consistent with current international consensus definitions of probable bruxism. Pelvic pain symptoms, erectile function, and anxiety levels will be evaluated using validated questionnaires.

Statistical analyses will be conducted to examine the relationships between bruxism and pelvic pain, erectile dysfunction, and anxiety. Correlation and group comparison analyses will be used to explore potential associations between these variables. The findings of this study may contribute to a broader understanding of the relationship between orofacial parafunctional activities and pelvic health outcomes. Identifying potential links between bruxism and pelvic floor-related symptoms may help support a multidisciplinary perspective in the assessment and management of men presenting with pelvic pain or sexual dysfunction.
