Obesity and periodontitis: A clinical study

J Indian Soc Periodontol. 2011 Jul;15(3):240-4. doi: 10.4103/0972-124X.85667.


Background: The aim of the study was to evaluate the relationship between obesity and periodontitis.

Materials and methods: A total of 300 subjects aged 20 years and above suffering from generalized periodontitis were recruited from Department of Periodontics, Pacific Dental College and Hospital, Udaipur. Periodontal status of the subjects was recorded. Body mass index and waist circumference were used as measure to assess obesity. Other variables like age, gender, oral hygiene index were also recorded.

Results: When evaluation was done for prevalence of periodontal disease according to BMI in obese and non-obese, the prevalence of periodontal disease was significantly (P=0.03) more in obese (88%) than in non-obese (74.4%) individuals. [OR=-20.4 and 95% confidence interval (CI) 1.3-1.3].

Conclusion: The prevalence of periodontal disease is higher among obese subjects. Obesity could be a potential risk factor for periodontal disease in all age groups.

Keywords: Body mass index; obesity; periodontal disease; waist circumference.
