Sleep disorders can affect on different organs and increase the risk of cardiovascular disease, diabetes, depression, immunity disorders and decrease the bone density. Periodontitis includes inflammation of periodontium because of increased or decreased response of the host immunity to predisposing factors (it can be in presence of systemic diseases). The aim of this study was to evaluate the relationship between sleep disorders and periodontal diseases.

In this analytic-cross sectional study, 60 individuals clinically healthy that referring to Department of Periodontology of Isfahan Dental School at year 2018-19 categorized into 2 groups: with or without dyssomnias (with PSQI questionnaire). In this study, Sillness and Loe plaque index, Loe and Sillness gingival index and calculus index were investigated. Similarly assessed demographic factors, personal health behaviors and relation between the severity of periodontitis and dyssomnia and were assessed. Data analyzed by SPSS statistics 16 software using independent T-test, Mann-Whitney, Pearson and multinominal regression.

Severity of periodontitis had a significant relationship with age, BMI (Body Mass Index), calculus index, frequency of flossing and brushing as well as score of PSQI questionnaire (p<0.5). By controlling age, gender, mass and plaque index, there was a significant relationship between dyssomnias and severity of periodontal disease in the patients with moderate periodontitis (P>0.001) and severe periodontitis (P=0.006), but in the case of mild periodontitis, the relationship was close to the significant level (p=0.087).

It seems that dyssomnias is in relation to severity of periodontitis; therefore sleep hygiene may help controlling periodontal diseases. However more studies are needed in this field.
