Abstract

Background and objective

Plasma leptin is associated in patients with inflammatory diseases. A high concentration of leptin is associated with healthy gingival tissue. The purpose of this study was to assess the concentration of human leptin in gingival crevicular fluid (GCF) and serum within healthy and diseased gingiva, further to explore the possibility of using the levels of leptin in GCF and serum as a biochemical marker of periodontal disease progression.

Materials and methods

Ninety subjects were selected with age (30-39 years) and sex (15 males and 15 females) matched, to eliminate age and sex as confounders. The subjects were divided into three groups consisting of 30 subjects in each group based on the clinical and radiological parameters; healthy (group I), gingivitis (group II), periodontitis (group III), from whom the GCF samples were collected with Periopaper GCF collection strips (Proflow, Amityville, NY, USA) for 30 seconds and blood samples with 20-gauge needle syringe respectively. Leptin concentration was determined from individual GCF and serum samples by enzyme-linked immunosorbent assay (ELISA).

Results

The highest mean leptin concentration in GCF was observed in group I (2,664.30 pg/ml ± 324.73) and least mean leptin concentration was obtained in group III (1,309.43 pg/ml ± 202.45). The mean concentration of group II (1,639.43 pg/ml ± 344.46) was intermediate between the highest and lowest values. In contrast, the highest mean leptin concentration in serum was obtained for group III (12,086.57 pg/ml ± 1,698.23) and least mean leptin concentration was obtained for group I (8,715.09 pg/ml ± 1,649.19). The mean concentration of the group II (10,694.01 pg/ml ± 1,777.72) were intermediate between the highest and lowest values.

Conclusion

The results indicated a statistically significant decrease in the GCF leptin concentration and increase in serum leptin concentration as the periodontal disease progressed.
