Abstract：【Objective】To investigate the effects of porcelain fused to metal crown (PFM) of different materials on the levels of inflammatory factors in periodontal tissue and gingival sulcus. 【Methods】A total of 60 patients who underwent dental restoration were selected from January 2013 to June 2015 and divided according to the repairing materials into group A (nichrome procelain crowns), group B (nickel-chrome gold-plated porcelain fused-to-metal crowns) and group C (gold-deposited porcelain crowns), with 20 cases in each group. The amount of Gingival crevicular fluid (GCF), sulcus probing depth (GCD), gingival index (GI) and tumor necrosis factor (TNF-α) alpha in gingival crevicular fluid were measured before and 6 months after repair. Interleukin -1 beta (IL-1β), interleukin -6 (IL-6) and interleukin -8 (IL-8) level were measured. 【Results】Before restoration, A group, B group and C group showed no significant difference in GCF, GCD and GI indexes (P>0.05). Six months after repair, the GCF, GCD, and GI indexes of patients in the A group were significantly increased (P<0.05); they were significantly higher than those of B group and C group (P<0.05). Before restoration, differences in the levels of TNF-α, IL-1β, IL-6 and IL-8 in gingival crevicular fluid of patients in A group, B group and C group had no statistical significance (P>0.05); 6 months after repair, TNF-α, IL-1 beta and IL-8 levels in patients in the A group were significantly increased compared to before restoration (P<0.05) and were significantly higher than those of B group and C group (P<0.05). 【Conclusion】The impact of nichrome alloy PFM on periodontal tissue in patients is more pronounced with higher levels of inflammatory factors in GCF.
