The Relationship Between Dental Anxiety and Oral Health-Related Quality of Life in Patients with Periodontitis

Objectives: This study aimed to (1) investigate whether dental anxiety (DA) and oral health-related quality of life (OHRQoL) differed between patients diagnosed with periodontitis and individuals with periodontal health, (2) examine associations and correlations between these patient-reported measures, and (3) analyze demographic and clinical parameters. Methods: Ninety-six patients diagnosed with periodontitis and age- and sex-matched periodontally healthy controls were included. Participants’ demographic characteristics, smoking status, current dental pain, dental pain during the last month, the Modified Corah’s Scale (MDAS), and the Oral Health Impact Profile (OHIP-14) were determined. Results: The mean age of participants was 48.51 years ± 11.41. Patients with periodontitis experienced higher pain in the last month compared to controls (p = 0.003). Patients with periodontitis exhibited significantly higher MDAS total and sub-scores (p < 0.001). Compared to controls, the periodontitis group indicated extreme DA (1.04% vs. 7.79%, p = 0.034). Patients with periodontitis feared having a foreign object in the mouth compared to controls (p = 0.004). The periodontitis group exhibited worse OHIP-14 global and sub-scores (all Ps < 0.001). Positive associations and correlations of MDAS total and sub-scores with OHIP-14 global and domain scores were found for the periodontitis group, but not for controls. Patients with periodontitis who reported “moderate and extreme anxiety” had poorer OHRQoL compared to controls (p = 0.001). The minimal importance difference for this finding indicates a large effect size and a moderate standardized response mean between groups. Conclusions: Patients with periodontitis had higher levels of DA and worse OHRQoL compared to controls. Our study highlights the importance of providing a comprehensive approach, including psychosocial well-being, when diagnosing and treating periodontal disease.
