Abstract:
Objective:To investigate the level of gingival crevicular fluid and serum gingival sulcus fluid Dickkopf-1 (DKK-1), macrophage inflammatory protein-1α (MIP-1α) and interleukin (IL)-17 in patients with chronic periodontitis and their clinical significance.Methods:80 patients with chronic periodontitis (observation group) and 40 healthy periodontal subjects (control group) were prospectively selected. The gingival index (GI), bleeding index (BI), probe depth (PD), loss of attachment (AL) levels were compared between the two groups. The IL-6, IL-8, tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), DKK1, MIP-1α and IL-17 levels in the gingival sulcus fluid and serum of the two groups were compared, and the correlation of DKK-1, MIP-1α and IL-17 levels with periodontal indexes and inflammatory factors in the observation group were analyzed. The DKK-1, MIP-1α and IL-17 levels in the gingival crevicular fluid and serum before and after treatment were compared among the patients with different disease degrees.Results:The levels of GI, BI, PD and AL in the observation group [(2.11±0.36)points, (3.76±0.65)points, (4.56±0.78)mm, (4.06±0.49)mm, respectively] were higher than those of the control group [(0.53±0.08)points, (1.61±0.33)points, (2.13±0.29)mm, 0 mm, respectively] (all P<0.05). The levels of IL-6, IL-8, TNF-α, DKK-1, MIP-1α and IL-17 in gingival crevicular fluid of the observation group [(65.23±9.30)ng/L, (310.19±42.95)ng/L, (40.46±9.70)ng/L, (13.70±3.62)μg/L, (19.67±8.14)μg/L, (315.84±53.76)pg/μl] were higher than those of the control group [(36.81±5.61)ng/L, (178.21±25.73)ng/L, (26.43±5.76)ng/L, (7.41±2.02)μg/L, (6.23±1.99)μg/L, (266.64±46.27)pg/μl, respectively] (all P<0.05). The serum levels of IL-8, TNF-α, DKK-1, MIP-1α and IL-17 in the observation group were also higher than those in the control group (all P<0.05). In the observation group, the levels of DKK-1, MIP-1α and IL-17 in gingival crevicular fluid and serum were positively correlated with eriodontal indexes (GI, BI, PD, AL) and the IL-8 and TNF-α levels (all P<0.05). In the observation group, the levels of DKK-1, MIP-1α and IL-17 in gingival crevicular fluid and serum of mild patients were lower than those of moderate to severe patients, and the levels of DKK-1, MIP-1α and IL-17 in mild and moderate to severe patients after treatment were also lower than those before treatment, with statistically significant difference (all P<0.05). Conclusions:The levels of DKK-1, MIP-1α and IL-17 in gingival crevicular fluid and serum of patients with chronic periodontitis are increased, which are closely related to the occurrence and development of chronic periodontitis. Detection of these indicators has certain significance for the diagnosis and treatment of the disease.
