Abstract:
Objective To investigate the clinical performance of fiber post restorations in elderly patients with residual root and crown and to analyze the factors affecting the clinical success rate.Methods A total of 66 elderly patients requiring post restoration were selected.They were randomly divided into two groups:the observation group (n=33,restored with fiber post-resin cores) and the control group (n=33,restored with cast metal post-cores).All patients were rechecked 1 year and 2years after the restoration.The clinical efficacy and the failure types were recorded.The differences in clinical performance between the 2 groups were compared by using Fisher's exact test.Results The differences in the gingival index and periodontal index in the 2 groups between the experimental teeth and the control teeth were zero.There were no significant differences in dental morphology,root canal treatment failure,tooth color matching and marginal coloration between the 2 groups (all P＞0.05).1 case with post debonding and 1 case with fiber post fracture were found in the observation group and 1 case with marginal coloration was found in control group.There was no significant difference in clinical success rate between the 2 groups (93.94％ vs.96.97％,P＞0.05).Conclusions The clinical success rate in fiber post-resin core restoration is the same as in cast metal post-cores restoration in elderly patients.
