Effect of fiber post,nano composite resin combined with zirconia porcelain crown on the restoration of wedge-shaped defect of teeth and its influences on the level of inflammatory mediator in gingival crevicular fluid and aesthetic score
Objective To explore the effect of fiber post,nano composite resin combined with zirconia porcelain crown on the restoration of wedge-shaped defect of teeth and its influences on the levels of inflammatory mediator in gingival crevicular fluid(GCF)and aesthetic score.Methods A total of 96 patients with wedge-shaped defect of teeth admitted from April 2018 to June 2021 were selected as the research objects and divided into control group and observation group by random number table method,with 48 cases in each group.The control group received metal post-core combined with metal porcelain crown restoration,and the observation group received fiber post,nano composite resin combined with zirconia porcelain crown restoration.The repair effects of the two groups were compared.Results The detection rate of oral pathogenic bacteria of the observation group was lower than that of the control group,and the repair success rate was higher than that of the control group(P＜0.05).After repair,the levels of neurokinin A(NKA),tissue inhibitors of metalloproteinases-1(TIMP-1),matrix metaloproteinase-9(MMP-9)and interleukin-8(IL-8)in GCF of the observation group were lower than those of the control group(P＜0.05).After repair,the scores of Pink Esthetic Score(PES)and White Esthetics Score(WES)in the observation group were higher than those in the control group(P＜0.05).After repair,the amount of GCF and levels of alkaline phosphatase(ALP)and aspartate aminotransferase(AST)in the observation group were lower than those in the control group(P＜0.05).Conclusion The restoration of wedge-shaped defect of teeth with fiber post,nano composite resin combined with zirconia porcelain crown can ameliorate the amount of GCF and the expression of inflammatory mediators,ALP and AST in GCF,and improve the success rate of restoration and aesthetic scores.
