Associations Between Mental Health and Oral Health in Saudi Arabia: An Online Survey-Based Cross-Sectional Study.

Abstract

Background Mental disorders cause psychological stress and lead to poor lifestyle behaviors and an increased risk of poor oral health. This study aims to explore the potential association between mental illnesses with oral health and personal oral care in the Saudi population. Methodology Saudi Arabians aged ≥18 years were eligible to participate in this cross-sectional study. The study questionnaire had the following five sections: demographics, a brief depression severity measure (Patient Health Questionnaire-9), a brief generalized anxiety disorder measurement tool (Generalized Anxiety Disorder-7), an oral health measurement tool, and personal oral health care. The data were analyzed using SPSS software version 26 (IBM Corp., Armonk, NY, USA). The results were presented as numbers and (percentages) or mean and standard deviations (SD). Results This study included a total of 522 participants. The mean scorefor dental health and care was 4 (SD = 1.9) and 13.6 (SD = 1.9), respectively, reflecting a moderate level of dental health and positive dental care. Males had better oral health, whereas females had better dental care. A college degree or higher was linked to better dental care, and chronic diseases were linked to lower dental health scores. Minimal depression had a significantly higher dental care score than mild-to-severe depression. Depression and anxiety did not affect dental health. Conclusions This study showed that minimal depression was associated with a higher dental care score than mild-to-severe depression. However, the degree of depression was not associated with dental health. Furthermore, anxiety had no association with dental health or care.
