Abstract

Aim: To evaluate whether obesity affects the subgingival microbial composition of patients with periodontal health or chronic periodontitis (CP). Materials and Methods: Based on periodontal parameters, body mass index and waist-hip ratio, 166 patients were allocated into one of the following groups: Normal weight (NW) patients with periodontal health (n = 44), NW patients with CP (n = 40), obese patients with periodontal health (n = 40) and obese patients with CP (n = 42). Six subgingival biofilm samples per patient were analysed for their content of 40 bacterial species using checkerboard DNA-DNA hybridization. Results: Obese patients with CP harboured higher levels and/or higher proportions of several periodontal pathogens than those with NW and CP, including Aggregatibacter actinomycetemcomitans, Eubacterium nodatum, Fusobacterium nucleatum ss vincentii, Parvimonas micra, Prevotella intermedia, Tannerella forsythia, Prevotella melaninogenica and Treponema socranskii. The proportions of most of these pathogens, as well Campylobacter rectus and Eikenella corrodens, were more increased in the diseased sites of the obese patients than in those with NW. Furthermore, the healthy sites of the obese patients, presenting or not CP, also exhibited higher proportions of some of the pathogens than patients with NW. Conclusions: Obesity is associated with increased levels and proportions of periodontal pathogens, especially in patients with CP. (AU)
