Abstract :
Background: Periodontitis is a public health concern since it is a major factor in tooth loss
worldwide and has association with many systemic diseases. Sleep is a complex and essentially
biological process and a critical factor for maintaining mental and physical health. Since inflammation
is characteristic of both chronic periodontitis and sleep deprivation, few studies in recent years
present the contradictory results regarding this potential association. The objective of the present
study was to investigate the association between quality of sleep and chronic periodontitis.
Materials and Methods: A total of 200 individuals participated in this study. All participants
underwent a comprehensive clinical periodontal examination. Case–control were identified using
the Centers for Disease Control and Prevention/American Academy of Periodontology case
definitions for periodontal disease. The quality of sleep was assessed by Pittsburgh Sleep Quality
Index. The univariate and multivariate logistic regression analysis was used to test the influence of
variables (quality of sleep, age, sex, ethnicity, education, and socioeconomic status), in the occurrence
of periodontitis. Odds ratio (OR) and respective confidence intervals (CIs) were calculated and
reported. P ≤0.05 was considered statistically significant.
Results: The prevalence of poor quality of sleep was 56.75% in cases (periodontitis group) and
43.24% in control group. There was positive association between quality of sleep and chronic
periodontitis (OR = 3.04; 95% CI = 1.42–6.5; P = 0.004). In multivariate logistic regression analysis,
only the age was significantly related to the periodontitis (OR = 1.11; 95% CI = 1.07–1.41; P < 0.001),
other variables failed to reach the significant level.
Conclusion: Poor quality of sleep was significantly associated with chronic periodontitis. Only the
age was significantly related to periodontitis among the other covariable measured.
