Objective: This transversal study aimed to evaluate and relate bone mineral density (BMD), body composition and periodontal disease among men.

Study Design: The sample consisted of 22 patients, aged 22 and 48 years, obese with BMI ≥ 40kg/m², candidates for bariatric surgery. Evaluations of dual energy X-ray absorptiometry (DXA), anthropometric and oral evaluation, gingivitis and periodontitis were performed. Pearson's correlation index was adopted (p < 0.05).

Results: The average weight was 148 kg (122-198); Average BMI of 48.8 kg/m2 (40.5-62.5); BMC (bone mineral content), on average, of 3.31kg (2.7-4.1); Mean total body BMD of 1.3 g/cm2 (1.1-1.5); and an average Z-score of 1.2 (0.0-2.9). The mean total body fat was 43.3% (37.4-52.1), and the percentage of total mas of fat free was 56.6 (47.9-82.3). The average FMI (fat mass index) was 20.6 (14.4-27.0), The A (android)/G (ginoid) ratio of 1.2 (1.0-1.6) and the average trunk weight, 85.8kg (68.3-116.2). 29% of patients had periodontal disease. There was a difference of less than 4.5 kg (1.0 to 7.8) in the weight of DXA compared to the anthropometric weight, which corresponds to an average difference of 3.06% (0.05-5.27). In the correlation analysis of the dental evaluation vs the DXA result, only significant correlation was obtained with gingival bleeding and the FMI (p = 0.031, R = -0.525).

Conclusion: It can be concluded that with the increase of fat mass there is a decrease in gingivitis, possibly due to the evolution of periodontal disease. Future studies should be conducted to clarify these preliminary findings.
