OBJECTIVE To determine the level of leptin in gingival crevicular fluid (GCF) of patients with aggressive periodontitis (AgP) and to analyze the relationship between leptin and periodontal cilinical parameters. METHODS Fifty-four patients with AgP and 30 healthy controls were recruited. Detailed clinical examinations were conducted, and clinical parameters such as bleeding index (BI), probing depth (PD), attachment loss (AL) were recorded. Two teeth were selected as test teeth in each subject, one from posterior area and the other from anterior region. The level of GCF leptin was measured by enzyme linked immunosorbent assay. RESULTS The level of GCF leptin in AgP patients was significantly lower than that of control subjects [(16.5±4.6) ng vs.(26.0±6.0) ng, P < 0.05]. The level of GCF leptin was negatively related to BI (-0.306, P < 0.01), PD (-0.346, P < 0.01) and AL (-0.250, P < 0.01). CONCLUSIONS AgP patients have significantly decreased level of GCF leptin and the level of leptin was negatively related to BI, PD and AL.

D010512 Periodontal Index A numerical rating scale for classifying the periodontal status of a person or population with a single figure which takes into consideration prevalence as well as severity of the condition. It is based upon probe measurement of periodontal pockets and on gingival tissue status.

D010520 Aggressive Periodontitis Inflammation and loss of PERIODONTIUM that is characterized by rapid attachment loss and bone destruction in the presence of little local factors such as DENTAL PLAQUE and DENTAL CALCULUS. This highly destructive form of periodontitis often occurs in young people and was called early-onset periodontitis, but this disease also appears in old people.

D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D005883 Gingival Crevicular Fluid A fluid occurring in minute amounts in the gingival crevice, believed by some authorities to be an inflammatory exudate and by others to cleanse material from the crevice, containing sticky plasma proteins which improve adhesions of the epithelial attachment, have antimicrobial properties, and exert antibody activity.

D016022 Case-Control Studies Comparisons that start with the identification of persons with the disease or outcome of interest and a control (comparison, referent) group without the disease or outcome of interest. The relationship of an attribute is examined by comparing both groups with regard to the frequency or levels of outcome over time.
