An observational study in Bruxism, sponsored by Ankara Yildirim Beyazıt University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-08-25.
Sponsored by Ankara Yildirim Beyazıt University · Observational
This observational case-control study aimed to compare biochemical factors related to calcium metabolism between adults with and without bruxism. Participants were classified into bruxism and control groups based on self-reported bruxism behaviors assessed using the BRUX Scale together with standardized clinical examination findings. Serum vitamin D, parathyroid hormone (PTH), calcium, albumin, and albumin-corrected calcium levels were evaluated and compared between the two groups. The study aimed to determine whether these biochemical parameters differ between individuals with and without bruxism and to provide further insight into their potential relationship with bruxism

The study population consisted of adults evaluated at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Ankara Yildirim Beyazit University. Eligible participants with suspected bruxism were assessed using self-reported bruxism behaviors and standardized clinical examination findings. Participants meeting the predefined criteria for bruxism constituted the bruxism group. Eligible participants without bruxism were selected as controls and matched to the bruxism group according to age and sex. Biochemical laboratory results available from the preceding 6 months were evaluated.
