Abstract：Objective:To observe the Th17 cytokines changes in gingival crevicular fluid of different kinds porcelain tooth after restoration.Method:96 cases with single-crown repair mandibular molar were divided into co-cr alloy group,galvanized forming group and zirconium dioxide group,the Th17 cytokines level in gingival crevicular fluid after respectively repair 1,3 months were detected.Result:IL-17 and IL-21 level in gingival crevicular fluid of co-cr alloy group after restoration 1,3 months were significantly higher than those before restoration(P<0.01 or P<0.05).IL-17 level in gingival crevicular fluid of galvanized forming group after restoration 1,3 months were higher than those before restoration(P<0.05),IL-21 level in gingival crevicular fluid after restoration 1,3 months were as same as before restoration(P>0.05).IL-17 and IL-21 level in gingival crevicular fluid of zirconium dioxide group after restoration 1,3 months were as same as before restoration(P>0.05).IL-17 and IL-21 level in gingival crevicular fluid of co-cr alloy group after restoration 1,3 months were higher than those of galvanized forming group and zirconium dioxide group(P<0.05).IL-17 level in Gingival crevicular fluid of galvanized forming group after restoration 1,3 months were higher than those of zirconium dioxide group(P<0.05).Conclusion:Galvanized forming and zirconium dioxide all porcelain crown are ideal restoration material,both are better than co-cr alloy.
