Abstract:
Objective:To detect the effects of porcelain-fused-to-metal(PFM)crown on the periodontal tissue of the restored teeth,and the relationship between the levels of intedeukin(IL)-1β,aspartate transaminase(AST)and alkaline phosphatase(ALP)in gingival crevicular fluid(GCF)and the health condition of periodontal tissue.Methods:Among 28 patients,34 maxillary incisors with PFM crowns were selected for the study.There were 19 Ni-Cr PFM crowns and 15 Au-Pt PFM crowns.The contralateral homonymy natural teeth were healthy and treated as control teeth.The patients were followed up 6 to 8 months after restoring crowns.The values of IL-1β,AST and ALP in GCF were analysed.Results:The concentrations of IL1β and ALP were significantly higher in GCF of Ni-Cr PFM compared with those of control,whereas no significant difference in Au-Pt PFM group compared with that of control.The level of GCF-AST was higher in Ni-Cr PFM and Au-Pt PFM group than that of healthy control.Conclusion:Ni-Cr PFM crowns have negative influence on periodontal tissue,but Au-Pt PFM have little influence on periodontal tissue of the restored teeth.The activity of IL-1β,AST and ALP of GCF are sensitive to reflect the effect of PFM crowns of different materials on periodontal tissue.
