Does Obstructive Sleep Apnea Increase the Risk for Periodontal Disease? A Case-Control Study.

Background: A possible association between periodontitis and obstructive sleep apnea (OSA) has been suggested. The aim of this study is to compare periodontitis prevalence between controls and patients with OSA by assessing clinical periodontal parameters and gingival crevicular fluid (GCF) levels of interleukin (IL)-1β, tumor necrosis factor (TNF)-α, and high-sensitive C-reactive protein (hs-CRP); serum hs-CRP was also sampled.

Methods: A case-control study was performed that included 163 individuals: 83 individuals (18 females and 65 males) with OSA and 80 non-OSA individuals (23 females and 57 males) as controls.

Plasma and salivary total antioxidant capacity in healthy controls compared with aggressive and chronic periodontitis patients.

Objectives: To evaluate the plasma and salivary total antioxidant capacity (TAOC) in patients with generalized chronic periodontitis (CP), generalized aggressive periodontitis (AgP), and periodontally healthy controls.

Methods: This cross-sectional study includes of 88 individuals seeking dental treatment at the Faculty of Dentistry, Istanbul University, Istanbul, Turkey between January 2011 and March 2012. Fifteen AgP patients were compared with 21 healthy controls (C1), while 36 CP patients were compared with 16 healthy controls (C2).
