Oral health is a critical component of overall well-being, and it is highly influenced by psychological factors. While mental health disorders are often associated with poor oral health, the impact of obsessive-compulsive 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. A cross-sectional survey was conducted among 384 biomedical students aged 18-30 years. Participants completed the Hiroshima University Dental Behavior Inventory (HU-DBI) to assess oral health behaviors and the Five Factor Obsessive-Compulsive Inventory-Short 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. The higher OCPD tendencies group was older ( = 0.003), with predominantly female students ( = 0.005), and with higher academic grades ( < 0.001). These participants exhibited significantly better HU-DBI total scores compared to the group with the lower tendencies (8.0 (7.0-8.0) vs. 7.0 (6.0-8.0); < 0.001). Traits such as perfectionism, fastidiousness, and punctiliousness were significantly associated with better oral hygiene practices ( < 0.001). 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.
口腔健康是整体健康的关键组成部分，并且受到心理因素的极大影响。虽然心理健康障碍常常与口腔健康不佳相关，但强迫型人格障碍（OCPD）倾向对口腔卫生行为的影响仍未得到充分研究。本研究旨在调查生物医学专业学生中OCPD倾向与口腔健康行为之间的关系。对384名年龄在18至30岁之间的生物医学专业学生进行了横断面调查。参与者完成了广岛大学牙科行为量表（HU-DBI）以评估口腔健康行为，并完成了五因素强迫量表简版（FFOCI-SF）以评估OCPD倾向，然后将他们分为高倾向组和低倾向组。还收集了社会人口统计学数据。使用适用于Windows的MedCalc计算机软件对所有收集的数据进行统计分析。OCPD倾向较高的组年龄较大（= 0.003），以女生为主（= 0.005），且学业成绩较高（< 0.001）。与倾向较低的组相比，这些参与者的HU-DBI总分显著更高（8.0（7.0 - 8.0）对7.0（6.0 - 8.0）；< 0.001）。完美主义、挑剔和一丝不苟等特质与更好的口腔卫生习惯显著相关（< 0.001）。我们的结果表明，生物医学专业学生中的OCPD倾向通过完美主义和注重细节等特质对口腔健康行为产生积极影响，不过过度僵化可能带来诸如刷牙过度等风险。然而，未来需要进行纵向大规模研究来验证这些发现。
