Evaluation of tumor necrosis factor-α (TNF-α) levels in plasma and their correlation with periodontal status in obese and non-obese subjects.

Khanna S, Mali AM - J Indian Soc Periodontol (2010)

Bottom Line: The BMI, TNF-α levels in plasma and Periodontal Disease Index (PDI) scores were assessed, compared and correlated.Significantly higher PDI scores and TNF-α levels were found in the obese group as compared to those in the non-obese group.Also, a significant and positive correlation was seen between BMI and TNF-α, TNF-α and PDI as well as BMI and PDI.

ABSTRACT

Background: Obesity is emerging as a significant health problem worldwide and is a risk factor for various systemic diseases. Periodontal disease is a multifactorial inflammatory disease. Recent evidence points to a link between obesity and periodontal disease, and a role for tumor necrosis factor-α (TNF-α) has been suggested.

Materials and method: FORTY NONDIABETIC SUBJECTS WERE DIVIDED INTO TWO GROUPS: group A (non-obese) included subjects with body mass index (BMI) of 18.5 to 27 kg/m2, and group B (obese) included subjects with BMI>27 kg/m2. The BMI, TNF-α levels in plasma and Periodontal Disease Index (PDI) scores were assessed, compared and correlated.

Results: Significantly higher PDI scores and TNF-α levels were found in the obese group as compared to those in the non-obese group. Also, a significant and positive correlation was seen between BMI and TNF-α, TNF-α and PDI as well as BMI and PDI.

Conclusion: Increase in the levels of tumor necrosis factor-a in plasma and an increase in the severity of periodontal disease may be seen in subjects with a higher body mass index (BMI). This indicates that obesity may be detrimental to the periodontal health of individuals.

Figure 3: Correlation between BMI and TNF-α among the subjects of the obese group

Mentions: Body mass index was correlated to (TNF-α) levels in plasma using Pearson's correlation coefficient.When allthe subjects (obese and non-obese) were considered together, the Pearson's correlation coefficient was 0.830 (P=.000). When only the obese group was considered, the Pearson's correlation coefficient was 0.902 (P=.000); and when only the non-obese group was considered, the Pearson's correlation coefficient was 0.573 (P=.008). Coefficients of correlation between BMI and TNF-α levels were statistically highly significant and also high, consistent and positive [Figures 3 and 4].
