While mental health disorders are often associated with poor oral health, the impact of obsessive\u2013compulsive personality disorder (OCPD) tendencies on oral hygiene behaviors remains underexplored. This study aimed to investigate the relationship between OCPD tendencies and oral health behaviors among biomedical students. Materials and Methods: A cross-sectional survey was conducted among 384 biomedical students aged 18\u201330 years. Participants completed the Hiroshima University Dental Behavior Inventory (HU-DBI) to assess oral health behaviors and the Five Factor Obsessive\u2013Compulsive Inventory\u2014Short Form (FFOCI-SF) to evaluate OCPD tendencies, and they were divided into high and low tendencies groups. Sociodemographic data were also collected. Statistical analysis of all collected data was performed using the MedCalc computer software for Windows\u00ae. Results: The higher OCPD tendencies group was older (p = 0.003), with predominantly female students (p = 0.005), and with higher academic grades (p &lt; 0.001). These participants exhibited significantly better HU-DBI total scores compared to the group with the lower tendencies (8.0 (7.0\u20138.0) vs. 7.0 (6.0\u20138.0); p &lt; 0.001). Traits such as perfectionism, fastidiousness, and punctiliousness were significantly associated with better oral hygiene practices (p &lt; 0.001). Conclusions: Our results suggest that OCPD tendencies in biomedical students positively influence oral health behaviors through traits like perfectionism and attention to detail, though excessive rigidity may pose risks such as over-brushing. However, future longitudinal larger-scale studies need to address these findings.<\/jats:p>","DOI":"10.3390\/medicina61040593","type":"journal-article","created":{"date-parts":[[2025,3,26]],"date-time":"2025-03-26T04:17:14Z","timestamp":1742962634000},"page":"593","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Association Between Oral Health and the Tendencies to Obsessive\u2013Compulsive Behavior in Biomedical Students\u2014A Questionnaire Based Study"],"prefix":"10.3390","volume":"61","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2060-5130","authenticated-orcid":false,"given":"Dinko","family":"Martinovic","sequence":"first","affiliation":[{"name":"Department of Maxillofacial Surgery, University Hospital of Split, 21000 Split, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matea","family":"Cernak","sequence":"additional","affiliation":[{"name":"Study of Dental Medicine, University of Split School of Medicine, 21000 Split, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3341-7625","authenticated-orcid":false,"given":"Slaven","family":"Lasic","sequence":"additional","affiliation":[{"name":"Department of Neurology, University Hospital Dubrava, 10000 Zagreb, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ema","family":"Puizina","sequence":"additional","affiliation":[{"name":"Department of Maxillofacial Surgery, University Hospital of Split, 21000 Split, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1959-0760","authenticated-orcid":false,"given":"Antonella","family":"Lesin","sequence":"additional","affiliation":[{"name":"Department of Maxillofacial Surgery, University Hospital of Split, 21000 Split, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mihaela","family":"Rakusic","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, University Hospital of Split, 21000 Split, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marino","family":"Lupi-Ferandin","sequence":"additional","affiliation":[{"name":"Study of Dental Medicine, University of Split School of Medicine, 21000 Split, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Jurina","sequence":"additional","affiliation":[{"name":"Study of Dental Medicine, University of Split School of Medicine, 21000 Split, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ena","family":"Kulis","sequence":"additional","affiliation":[{"name":"Study of Dental Medicine, University of Split School of Medicine, 21000 Split, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1634-0635","authenticated-orcid":false,"given":"Josko","family":"Bozic","sequence":"additional","affiliation":[{"name":"Department of Pathophysiology, University of Split School of Medicine, 21000 Split, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"125","DOI":"10.1177\/0022034516682718","article-title":"A New Definition for Oral Health: Implications for Clinical Practice, Policy, and Research","volume":"96","author":"Lee","year":"2017","journal-title":"J.
