The statistical population consisted of patients attending private dental clinics in Ramsar in 2025. A total of 60 individuals, including 30 patients with dental anxiety and 30 patients without dental anxiety, were selected through purposive sampling. Data collection instruments included the Dental Anxiety Inventory (DAI; Stouthard et al., 1993), Patient Health Questionnaire-15 (PHQ-15; Kroenke et al., 2002), Somatoform Dissociation Questionnaire-20 (SDQ-20; Nijenhuis et al., 1996), Anxiety Sensitivity Index (ASI; Taylor &amp; Cox, 1998), Orbach &amp; Mikulincer Mental Pain Questionnaire (OMMP; Orbach et al., 2003), and Self-Care Questionnaire (SCQ; Lowe &amp; Owen, 1996). Data were analyzed using multivariate analysis of variance (MANOVA) with SPSS-24 software.</p> <p><strong>Findings: </strong>The results of multivariate analysis of variance demonstrated significant differences between patients with and without dental anxiety in somatization, somatoform dissociation, anxiety sensitivity, psychological pain, and self-care behaviors (P &lt; 0.001). Patients with dental anxiety showed significantly higher levels of somatization, somatoform dissociation, anxiety sensitivity, fear of cardiovascular-gastrointestinal symptoms, fear of respiratory symptoms, fear of publicly observable anxiety reactions, fear of cognitive dyscontrol, and psychological pain compared to patients without dental anxiety. In contrast, self-care behaviors were significantly lower among patients with dental anxiety.</p> <p><strong>Conclusion: </strong>The findings suggest that dental anxiety is associated with heightened bodily symptom expression, dissociative bodily experiences, fear of anxiety-related sensations, and increased psychological pain, while simultaneously reducing adaptive self-care behaviors.</p> https://www.maherpub.com/index.php/jndd/article/download/789/618
