Evaluation of association between potential stress markers and periodontal health in medical and dental students: A questionnaire-based study

AIMS AND OBJECTIVES: Psychological conditions, particularly psychosocial stress, have been implicated as risk indicators for periodontal disease. The aim of the present study was to explore the role of psychosocial stress on periodontium through questionnaire and serum cortisol level. SUBJECTS AND METHODS: Two hundred medical and dental undergraduates were recruited for the study. Case group included 82 examination going and control group had 79 nonexam going students. Their stress level was evaluated using a standard questionnaire (perceived stress scale). Gingival index, periodontal disease index, bleeding on probing index, serum cortisol level, and serum alpha-amylase level were also measured. STATISTICAL ANALYSIS USED: Bivariate correlations and multiple regression tests were done. RESULTS: A positive correlation was found among stress scores, salivary cortisol, alpha-amylase, and periodontal disease measures. CONCLUSION: Periodontitis can be related to immunologic changes related to psychological states
