Background and Objective: Oxidative modification of low‐density lipoprotein (LDL) occurs in various diseased tissues and sites of local inflammation. For example, an increased plasma oxidized low‐density lipoprotein (OxLDL) level is a well‐known risk marker for cardiovascular diseases. Gingival crevicular fluid, the exudate from gingival tissues into the sulci, can be easily collected in a non‐invasive manner. However, the possible presence of OxLDL in gingival crevicular fluid has not been studied. In this study, we established a procedure to measure OxLDL in human gingival crevicular fluid.
Material and Methods: Human gingival crevicular fluid was sampled with paper points or paper strips. The gingival crevicular fluid samples from healthy gingival sulci (pocket depth |

Background and Objective: Oxidative modification of low‐density lipoprotein (LDL) occurs in various diseased tissues and sites of local inflammation. For example, an increased plasma oxidized low‐density lipoprotein (OxLDL) level is a well‐known risk marker for cardiovascular diseases. Gingival crevicular fluid, the exudate from gingival tissues into the sulci, can be easily collected in a non‐invasive manner. However, the possible presence of OxLDL in gingival crevicular fluid has not been studied. In this study, we established a procedure to measure OxLDL in human gingival crevicular fluid.
Material and Methods: Human gingival crevicular fluid was sampled with paper points or paper strips. The gingival crevicular fluid samples from healthy gingival sulci (pocket depth < 4 mm, n = 14) were subjected to western blot and/or sandwich ELISA. The amounts of OxLDL and LDL were measured by sandwich ELISA using an anti‐oxidized phosphatidylcholine monoclonal antibody and two anti‐apolipoprotein B antibodies. Venous blood samples were analyzed biochemically.
Results: We tested two methods of gingival crevicular fluid collection, namely paper points and paper strips. Gingival crevicular fluid could be collected very safely with paper points and they showed good recovery of LDL and OxLDL throughout the analysis. Apolipoprotein B, the major protein component in LDL, was detected in gingival crevicular fluid by western blot, and OxLDL was found to be present in gingival crevicular fluid by ELISA. The OxLDL/LDL ratio in gingival crevicular fluid was 17.0 times higher than that in plasma.
Conclusion: This is the first report to show the presence of apolipoprotein B and apolipoprotein B– oxidized phosphatidylcholine complex, which correspond to LDL and OxLDL, respectively, in gingival crevicular fluid.</description><identifier>ISSN: 0022-3484</identifier><identifier>EISSN: 1600-0765</identifier><identifier>DOI: 10.1111/j.1600-0765.2009.01226.x</identifier><identifier>PMID: 19778326</identifier><language>eng</language><publisher>Oxford, UK: Blackwell Publishing Ltd</publisher><subject>Apolipoproteins B - analysis ; Apolipoproteins B - blood ; Biological and medical sciences ; Blotting, Western ; Cholesterol - analysis ; Cholesterol - blood ; Cholesterol, HDL - analysis ; Cholesterol, HDL - blood ; Cholesterol, LDL - analysis ; Cholesterol, LDL - blood ; Dentistry ; Enzyme-Linked Immunosorbent Assay ; Female ; Gingiva - metabolism ; gingival crevicular fluid ; Gingival Crevicular Fluid - chemistry ; Gingival Pocket - metabolism ; Humans ; Lipoproteins, LDL - analysis ; Lipoproteins, LDL - blood ; low-density lipoprotein ; Male ; Medical sciences ; Middle Aged ; Otorhinolaryngology.
