ABSTRACT
Background Recurrent aphthous stomatitis (RAS) is a chronic oral ulcerative condition with an elusive etiology that is associated with excruciating pain. Psychological factors have been suspected as a possible risk factor in its onset and development. Depression, anxiety, and stress play pivotal roles in how people experience pain. Hence, we aimed to explore the relationship between depression, anxiety, stress, and the severity of pain perceived due to recurrent ulcers in RAS patients. Materials and methods A cross-sectional comparative study was conducted on 248 patients, comprising 124 diagnosed with RAS and 124 healthy subjects without this oral condition. Patients from both of these groups were matched with regard to age and sex and recruited over a period of one year from a dental hospital in Bengaluru, India. Patients with any other oral lesions, painful oral conditions, or systemic and psychological illnesses were excluded. Depression, anxiety, and stress were assessed in these patients using the Depression Anxiety Stress Scale 21 (DASS-21). Utilizing a Visual Analog Scale, ulcer-related pain was assessed in patients with RAS. The data were analyzed using the chi-square test and Pearson's correlation test in IBM SPSS Statistics for Windows, Version 26.0 (released 2019, IBM Corp., Armonk, NY). Results The chi-square analysis showed that participants with RAS showed a statistically significant higher prevalence of extreme stress (n = 39, 31.5%), extreme anxiety (n = 82, 66.1%), and depression (n = 38, 30.6%) as opposed to those without this oral condition. A moderately positive correlation was observed in the Pearson's test between the severity of pain experienced and stress and anxiety (r = 0.65 and 0.60, respectively, p < 0.05), while a mild positive correlation was observed between the severity of pain and depression (r = 0.35, p < 0.05). Conclusion Depression, anxiety, and stress influenced the severity of pain in these lesions, dictating the need for a holistic approach that integrates psychological interventions in the management of such chronic oral conditions with psychological links.
