Investigating the Potential Association between Functional Dyspepsia and Oro-Dental Health

Objectives: The aim of this study is to assess the relationship between dyspepsia and orodental status in patients diagnosed with functional dyspepsia (FD) and uninvestigated dyspepsia (UD). Materials and Methods: A cross-sectional study was conducted from February to July 2018, involving orodental examinations of 199 participants. The participants were divided into three groups: FD, UD, and a control group. FD diagnosis was made based on the Rome III criteria. The Glasgow Dyspepsia Severity Score was applied to patients with FD. The orodental examination included the assessment of missing, decayed, and filled teeth, tooth mobility, erosion, and mucosal inflammation. Statistical analysis was performed using multivariate logistic regression. Results: No significant association was observed between orodental health and FD or the control group. However, subgroup analysis revealed a significant association between decayed teeth, eating within 20 minutes, and oral mucosal inflammation with UD. Additionally, a statistically significant relationship was found between low educational level and functional dyspepsia. No significant relationship was identified between the Glasgow Dyspepsia Severity Score, demographic data, and orodental health. Conclusion: This study identified a positive association between low educational status and FD, as well as a correlation between decayed teeth, oral mucosal inflammation, and eating habits (specifically eating faster than 20 minutes) with UD.
