Association of Stress, Serum Cortisol Level, and Periodontal Status in Coal Mine Workers: A Clinico-Biochemical Study

Background: Occupational stress is a prevalent health concern among coal mine workers due to physically demanding and hazardous work conditions. Chronic stress can dysregulate the hypothalamic-pituitary-adrenal axis, leading to elevated serum cortisol levels, which may contribute to systemic and oral health disturbances. Periodontal disease, a chronic inflammatory condition of the supporting structures of the teeth, has been linked to both psychological stress and altered immune responses. Aim: This clinico-biochemical study evaluated the association between perceived stress, serum cortisol levels, and periodontal status among coal mine workers. Methodology: A cross-sectional study of 40 healthy coal mine workers was included in the study. The examiner measured the serum cortisol levels, clinical indices (Gingival Index, Plaque Index, probing pocket depth [PPD], etc.), and stress levels using perceived stress scale. Results: The data were analyzed and a correlation between cortisol and Periodontal Disease Index, cortisol and stress scale, and stress and PPD was observed to be statistically significant. Conclusion: The study suggests a strong link between occupational stress, serum cortisol levels, and periodontal health in coal mine workers, highlighting the need for stress management and oral health interventions in this population.
