Title	A High BMI is Associated with Periodontal Disease; However, it Remains Unclear as to the Exact Extent of the Magnitude of the Association
Clinical Question	Are patients with periodontitis who have elevated BMI at greater risk of disease progression as compared to patients with normal BMI?
Clinical Bottom Line	A high BMI is associated with periodontal disease; however, it remains unclear as to the exact extent since BMI alone is not an adequate indicator of obesity. The BMI measurement needs to be followed up by other body fat index qualifications in order to understand the exact magnitude of the association. The evidence strongly supports this conclusion as it is based on a systemic review and meta-analysis.

PubMed ID Author / Year Patient Group Study type (level of evidence) 21348914 Suvan/2011 Several thousand adult subjects were from 12 countries in Asia, Europe, and North America. Systemic Review Key results Meta-analysis indicated statistically significant associations between periodontitis and body mass index (BMI) category obese OR 1.81 (1.42, 2.30), overweight OR 1.27 (1.06, 1.51) and obese and overweight combined OR 2.13 (1.40, 3.26).

Comments on The Evidence	This is a systemic review investigating the correlation between overweight/obesity and periodontal disease. RCTs, cohort, case-control and cross-sectional study designs were used along with meta-analysis. Out of 526 titles and abstracts, 61 full text articles and abstracts were selected for further screening; 33 were selected. Nineteen studies were used in meta-analysis.
Applicability	The systemic review included an overview of the characteristic of the articles that were used. This study is helpful in our clinical setting.
