Comparison of Periodontal Inflammatory Parameters and Whole Salivary Cytokine Profile Among Saudi Patients with Different Obesity Levels

The aim of the present study was to compare clinical periodontal parameters and salivary interleukin (IL)-1 beta and IL-6 levels in patients with different obesity levels. A total of 419 individuals with class I, II, and III obesity and nonobese with chronic periodontitis were included. Clinical periodontal parameters were recorded, and whole salivary IL-1 beta and IL-6 were quantified using enzyme-linked immunosorbent assay. Clinical parameters and salivary cytokine concentrations were analyzed using one-way analysis of variance. For multiple comparisons, Bonferroni post hoc adjustment test was used. Clinical periodontal parameters and salivary IL-1 beta and IL-6 levels were statistically significant in class II and class III obese as compared to class I obese patients (P < .01) but were comparable between class II and class III obese individuals. These findings should be interpreted with caution due to the inclusion of hyperglycemic patients.
