[Effect of oral implant restoration on dentition defect patients and its impact on TNF-α and IL-6 levels in gingival crevicular fluid].

ABSTRACT

PURPOSE: To investigate the clinical effects of oral implant restoration in patients with dentition defects and the its impact on tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) levels in gingival crevicular fluid. METHODS: Eighty-four patients with dentition defects from May 2017 to August 1919 in People's Hospital of Shanghai Pudong District were enrolled and randomly divided into control group (n=42) and experimental group (n=42). Patients in the control group were repaired by routine methods,while those in the experimental group were treated with oral implant restoration. The effect of restoration was evaluated 6 months after treatment. The levels of TNF-α, IL-6 in the gingival crevicular fluid and dental function were compared between the 2 groups. The data were analyzed using SPSS 18.0 software package. RESULTS: The levels of TNF-α and IL-6 in the experimental group and the control group after treatment were significantly higher than those before treatment (P<0.05). The levels of TNF-α and IL-6 in the experimental group were significantly lower than those in the control group 6 months after treatment (P<0.05). The scores of dental function in the experimental group and the control group were significantly higher than those before treatment (P<0.05). The scores of retention, speech, chewing and aesthetics of the experimental group 6 months after treatment were significantly higher than the control group (P<0.05). The incidence of infection, pricking, post and core loosing and teeth missing in the experimental group was significantly lower than that of the control group (P<0.05). CONCLUSIONS: In the treatment of patients with dentition defects, implant restoration has little effect on the levels of TNF-α and IL-6 in gingival crevicular fluid, which is helpful to improve dental function and reduce the incidence of postoperative complications. Therefore, it is worthwhile to be popularized in clinical application.
