Association Between Severe Periodontitis and Obesity Degree: A Preliminary Study
Purpose:
To evaluate the association of severe periodontitis with overweight and obesity.
Material And Methods:
Full-mouth periodontal examination was performed on a random sample of 80 obese, 69 overweight and 87 normal-weight individuals (≥ 18 years). Severe periodontitis was defined using the Centers for Disease Control and Prevention - American Academy of Periodontology (CDC-AAP) case classification. Weight (kg) and height (m) were measured by a single examiner, body mass index (BMI) was calculated, and the subjects were classified as normal range, overweight and obese according to World Health Organization definitions. Interviews using a structured questionnaire were performed to collect data on demographics as well as socioeconomic and health status. Chi-squared and logistic regression tests were used to assess the association between severe periodontitis and obesity (p ≤ 0.05).
Results:
Although severe periodontitis was significantly associated with obesity (OR = 3.25, 95% CI = 1.27-8.31, p = 0.01), it was not associated with overweight (p = 0.59).
Conclusions:
In the present study, severe periodontitis was associated with obesity but not with overweight. Patients diagnosed with obesity should be referred for periodontal evaluation.

For example, suppose there are three unknown numbers whose mean is 10; although we can freely assign values to the first and second numbers, the value of the last number can not be arbitrarily assigned.

The degree of unsaturation for hydrocarbons is U = (2C + 2 − H) / 2, where C is the number of carbon atoms and H is the number of hydrogen atoms.
