title: Exploring association between sleep deprivation and chronic periodontitis: A pilot study.
abstract: BACKGROUND
  Sleep deprivation has become a global phenomenon, and epidemiologic data indicate that short sleep duration adversely impacts human physical health. Underlying mechanisms involve modulation of immune-inflammatory mechanisms. These changes might contribute to potentiation of destructive periodontal disease. Therefore, the present study aimed to assess if there is an association of sleep deprivation with chronic periodontal diseases.
  
  
  METHODS
  Sixty subjects were categorized into 3 groups (n = 20 each) viz. clinically healthy, gingivitis and periodontitis. Periodontal status of subjects was assessed by gingival index and pocket probing depth. All the study subjects were administered Pittsburgh Sleep Quality Index (PSQI) questionnaire for the assessment of sleep deprivation.
  
  
  RESULTS
  Present investigation revealed that mean PSQI was highest in the periodontitis group as compared to other two groups and the difference among three groups was statistically significant.
  
  
  CONCLUSIONS
  The present study with preliminary results suggestive of the association of sleep deprivation with severity of periodontal disease, definitely calls on for future studies with larger samples.
