Background: Working environment has a huge impact on both general and oral health. Coal mining is one of the age-old industries throughout the world and in India. Occupational stress is high among coal mine workers. Stress contributes to periodontal disease severity and progression. In literature, there is hardly any information available regarding the estimation of stress among coal mine workers. Thus, the purpose of the study was to estimate stress in terms of salivary cortisol levels and to correlate the same with periodontal disease severity among coal mine workers in Tamil Nadu. Methods: Forty systemically healthy coal mine workers above 18 years of age were enrolled in the study. Information regarding socioeconomic status and habits, followed by clinical examination including periodontal parameters such as probing pocket depth (PPD), clinical attachment level (CAL), number of missing teeth, and Periodontal Screening and Recording (PSR) Index were recorded using a standard pro forma. Unstimulated saliva was collected, and cortisol levels were measured using enzyme-linked immunosorbent assay. Pearson's correlation was done to correlate the salivary cortisol level and periodontal parameters. Results: The salivary cortisol level was assessed for 40 participants. Out of 40 participants, 80% of them were either user of smoking or smokeless forms or both. Only 20% were nonusers. The mean salivary cortisol levels were found to be higher among the past smokers and current users of smokeless tobacco (9.31 ± 0). There was a positive correlation between CAL, PPD, PSR, and missing teeth and salivary cortisol levels ( r = 0.801, 0.800, 0.581, and 0.473, respectively) and were statistically significant. Conclusion: Our results suggest that there was a high correlation between salivary cortisol and periodontal disease severity among coal mine workers and the results were statistically significant.
