Prevalence of Chronic Periodontitis and Chronic Stress in the South Indian Population.

Background Chronic stress is commonly thought to have a net negative effect on the efficacy of the immune response, leading to an imbalance between host and parasite and consequently resulting in a periodontal breakdown. Aim To identify the prevalence of chronic periodontitis and chronic stress as well as a comparative evaluation of clinical, demographic, and psychoanalytical parameters among the South Indian population. Materials and methods A total of 500 subjects between the ages of 30 and 60 were chosen from the Trivandrum district, Kerala, using multistage random sampling. Subjects were evaluated based on psychoanalytical parameters as well as periodontal examination. Psychoanalytical parameters were measured by the questionnaire method using the perceived stress scale. Periodontal parameters examined were the probing depth, clinical attachment loss, bleeding on probing, simplified oral hygiene index, and community periodontal index (loss of attachment). Statistical Analysis Categorical and quantitative variables were expressed as frequency (percentage) and mean ± SD respectively. Logistic regression analysis was used to analyze the association between the periodontal variables and psychoanalytical variables. All the statistical analysis was performed using IBM Statistical Package for Social Sciences (SPSS) Statistics for Windows (IBM Corp., USA). Results A total of 500 subjects, of whom 308 (61.6%) were female and 192 (38.1%) were male, participated in this study. The overall prevalence of periodontitis among all the subjects was found to be 42.4%, and the proportion of periodontitis among the stressed participants was found to be 46.2%, which is 10% higher compared to the non-stressed (36.1%) participants. Conclusion Our study showed an increased frequency of periodontitis among the stressed subjects as compared to the non-stressed subjects. These findings suggest that there is a positive association between chronic stress and chronic periodontitis, but further prospective studies are required to establish the extent of the effect chronic stress has on chronic periodontitis and vice versa.
