RT Journal Article SR Electronic T1 Plasma and salivary total antioxidant capacity in healthy controls compared with aggressive and chronic periodontitis patients JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 856 OP 861 DO 10.15537/smj.2015.7.11954 VO 36 IS 7 A1 Ulku Baser A1 Hikmet Gamsiz-Isik A1 Emine Cifcibasi A1 Evin Ademoglu A1 Funda Yalcin YR 2015 UL http://smj.org.sa/content/36/7/856.abstract AB 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). Clinical periodontal measurements were recorded, and plasma and saliva samples were collected. The TAOC of the plasma and saliva samples were determined using a commercially available colorimetric kit.Results: The plasma TAOC of both AgP and CP patients was significantly lower for C1 and C2. The salivary TAOC of CP patients was significantly lower for C2, but there was no significant difference between AgP patients and C1.Conclusion: Our results demonstrate that severe periodontitis may be associated with a lower plasma antioxidant capacity. The reduced antioxidant capacity in patients with severe periodontitis, especially with aggressive forms may be an important contributing factor to severe tissue destruction.
