Objective: The aim of this study was to evaluate the serum levels of lipids in patients with normal weight (NW) or obesity with or without chronic periodontitis (ChP).
Materials And Methods: One hundred and sixty non-smoking patients without history of diabetes and/or cardiovascular events were allocated into one of the following groups: NW patients with periodontal health (NWH; n = 40), NW patients with ChP (NWChP; n = 40), obese patients with periodontal health (ObH; n = 40), and obese patients with ChP (ObChP; n = 40). Serum levels of total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL), and triglycerides (TRG) were estimated.
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.
Aim: This study evaluated the effects of scaling and root planing (SRP) on gingival crevicular fluid (GCF) and serum levels of adipokines in patients with chronic periodontitis (CP) with or without obesity.
Methods: Twenty patients with obesity and 20 patients without obesity, all with CP, received SRP. Serum and GCF levels of resistin, adiponectin, leptin, tumour necrosis factor [TNF]-α and interleukin [IL]-6 were evaluated by enzyme-linked immunosorbent assay at baseline, 3, 6 and 12 months post-therapy.
Background: Despite several investigations suggesting that obesity is a risk indicator for periodontitis, little is known about the effect of obesity on periodontal treatment response. The aim of this study is to evaluate the effects of scaling and root planing (SRP) on clinical parameters and circulating levels of leptin and adiponectin in patients with obesity with chronic periodontitis (CP).
Methods: Twenty-four patients with obesity and CP and 24 patients without obesity with CP were submitted to SRP.
Background: We have recently developed a periodontal diagnostic tool that was validated in non-smokers with periodontitis. Tobacco smoking is a recognized risk factor for periodontal diseases that can mask gingival bleeding and lead to a false negative diagnosis. Therefore, the purpose of current study is to further validate this instrument in smokers with periodontal diseases.

Materials And Methods: Wistar and SHR were assigned to one of the following groups: normotensive rats (NTR) (n = 15), untreated SHR (n = 15), and lercanidipine-treated SHR (n = 15). The latter group was treated daily with lercanidipine for 6 weeks.
Background: The aim of this study is to evaluate the local and circulating levels of adipocytokines (resistin, adiponectin, leptin, tumor necrosis factor [TNF]-α, and interleukin [IL]-6) in individuals who are obese and individuals who are normal weight (NW) with chronic periodontitis (CP).
Methods: Periodontal and anthropometric examinations were performed. Based on these measurements, the individuals were divided into one of the following groups: NW non-periodontitis (NP) (NWNP; n = 20); NWCP (n = 20); obese NP (ONP; n = 18); and obese CP (OCP; n = 20).
Background: The aim of this study is to evaluate the gene expression of immune-inflammatory markers in gingival biopsies of patients with type 2 diabetes with chronic periodontitis (CP).
Methods: Gingival biopsies were harvested from systemically and periodontally healthy patients (SPH), systemically healthy patients with CP (SHCP), and patients with better-controlled and poorly controlled diabetes and CP. The levels of mRNA of interleukin (IL)-17, IL-6, IL-23, IL-10, IL-4, interferon-γ, toll-like receptor (TLR)-2, TLR-4, osteoprotegerin, receptor activator of nuclear factor-kappa B ligand (RANKL), tumor necrosis factor-α, transforming growth factor-β, transcription factor forkhead box p3, transcription factor orphan nuclear receptor C2 (RORC2), and receptor of advanced glycation end products (RAGE) were evaluated by quantitative real-time polymerase chain reaction.

Background: The aim of this study is to evaluate the levels of osteoclastogenesis-related factors (soluble receptor activator of nuclear factor-kappa B ligand [sRANKL] and osteoprotegerin [OPG]) in gingival crevicular fluid (GCF) from subjects with poorly and well-controlled type 2 diabetes and chronic periodontitis before and after periodontal therapy.
Methods: Eighteen subjects with well-controlled diabetes (glycated hemoglobin [HbA1c] levels ≤ 8%) and 20 subjects with poorly controlled diabetes (HbA1c levels >8%) were enrolled in this study. All subjects were submitted to non-surgical periodontal therapy.
Background: This study evaluates the ligature-induced bone loss (BL) and quality of tooth-supporting alveolar bone in spontaneously hypertensive rats (SHRs) by histometric, histochemical, and immunohistochemical analyses and assesses the effects of lercanidipine on these parameters.
Methods: Wistar rats and SHRs were assigned to one of the following groups: normotensive rats (n = 15), untreated SHRs (n = 15), and treated SHRs (n = 15). The latter group was treated daily with lercanidipine for 45 days.
