[The expression and clinical significance of IL-35 in periodontitis and oral lichen planus].

PURPOSE: To investigate the influence of IL-35 in the pathogenesis of periodontitis and oral lichen planus, and the correlation between periodontitis and oral lichen planus patients.

METHODS: The gingival crevicular fluid（GCF） and serum were collected from patients with oral lichen planus (n=20), periodontitis (n=20), periodontitis and oral lichen planus (n=20) and healthy controls (n=12). The patients' basic information, probing depth, clinical attachment loss, gingival index, sulcus bleeding index were measured and collected. The expression of IL-35 in GCF and serum was detected by ELISA. SPSS19.0 software package was used for statistical analysis.

RESULTS: The concentration of IL-35 in patients with periodontitis and oral lichen planus was significantly higher than that of other groups(P<0.05). There was significantly positive correlation between IL-35 level and periodontal clinical parameters.

CONCLUSIONS: Periodontitis and oral lichen planus may increase the concentration of IL-35 both in serum and GCF. The expression of IL-35 was positively correlated with periodontitis and oral lichen planus.
