Methods: 197 TMD pain patients were clinically examined and responded to DC\/TMD OBC (Oral Behaviour Checklist) and Axis II comprehensive instruments. Patients were divided into Pain Drawing (PD) profile subgroups: PD-1 = head\/face pain\u037e PD-2 = head and neck\/shoulder regional pain\u037e PD-3 = widespread pain. Using the Graded Chronic Pain Scale 2.0 assessing pain-related intensity\/interference, the patients were classified into TMD subtypes 1\u20133. Associations of frequent sleep bruxism (4\u20137 times per week) and daytime clenching (most\/all of the time) with explanatory variables were evaluated with Independent Samples Kruskal-Wallis and chi-square tests and pairwise comparisons were made with Mann-Whitney U-test with Bonferroni correction. Results: Frequent sleep bruxism was reported by 46.2% and daytime clenching by 67.5% of the participants. Sleep bruxism and daytime clenching associated significantly with muscle-related TMD diagnoses. Sleep bruxism and daytime clenching were significantly associated with anxiety (GAD-7, General Anxiety Disorder-7) subgroups, the highest prevalence being in the most severe subgroups. Frequent sleep bruxism was reported more by participants in TMD subtype 2 as well as those in PD-2 and PD-3 profile subgroups, with significant differences between PD-1 vs. PD-2 and between PD-1 vs. PD-3. Conclusions: Oral parafunctions are associated with muscle-related TMD diagnoses, anxiety symptoms and wider body pain, which should be considered in the assessment, treatment planning and personalized care of TMD pain patients.<\/jats:p>","DOI":"10.22514\/jofph.2025.074","type":"journal-article","created":{"date-parts":[[2025,12,12]],"date-time":"2025-12-12T08:30:58Z","timestamp":1765528258000},"page":"173","source":"Crossref","is-referenced-by-count":1,"title":["Association between parafunctional behaviors, clinical diagnoses, psychosocial factors and pain widespreadness in Finnish TMD pain patients in tertiary care"],"prefix":"10.22514","author":[{"given":"Arvid","family":"Iljin","sequence":"first","affiliation":[{"name":"Research Unit of Population Health, University of Oulu, 90570 Oulu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"26027","published-online":{"date-parts":[[2025,12,12]]},"container-title":["Journal of Oral &amp; Facial Pain and Headache"],"original-title":[],"deposited":{"date-parts":[[2025,12,12]],"date-time":"2025-12-12T08:30:59Z","timestamp":1765528259000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.jofph.com\/articles\/10.22514\/jofph.2025.074"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,12,12]]},"references-count":0,"URL":"https:\/\/doi.org\/10.22514\/jofph.2025.074","relation":{},"ISSN":["2333-0384","2333-0376"],"issn-type":[{"value":"2333-0384","type":"print"},{"value":"2333-0376","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,12,12]]}}}
