Abstract:
Objective To investigate the clinical effect of porcelain fused for metal crown restoration after root canal therapy.Methods Totally 90 patients with pulpitis or periapical periodontitis from December 2013 to December 2015 had their clinical data analyzed,who underwent root canal therapy and were divided equally into an observation group and a control group.The observation group took porcelain endocrowns repair and the control group applied ceramic crown.The two groups were compared on the restoration integrity,edge sealing,residual rate,gum,food impaction and color 3 months,6 months and 1 a after treatment.Results The observation group behaved significantly better than the control group in the edge sealing and restoration integrity (P＜0.05).There were significant differences between the residual rates,gum and food impaction in the two groups (P＜0.05).Conclusion Porcelain endocrowns repair gains advantages over ceramic crown repair in edge sealing,integrity,gum,food impaction and color after root canal therapy,though its long-term effect needs further investigation.
