Abstract:
Objective To compare the clinical effects of fiber post‐retained and metal post‐retained restorations .Methods Two hundred teeth after root canal therapy from 176 patients were divided into 2 groups randomly and each group consisted of 100 teeth .In the experimental group ,teeth were restored with fiber post‐resin core and porcelain crown ,where cast metal‐core and porcelain crown were used in the control group .The teeth were clinically examined regularly for 2 years .The data were analyzed with Chi‐square method .Results At the end of the 2‐year follow‐up ,6 fiber posts dislocated and 2 teeth showed gingival inflammation in the experimental group ,with a clinical success rate of 92% ,the loss rate of 6% .5 gingival inflammation cases ,2 periapical inflammation cases and 7 cases of root fracture occurred in the metal post group ,and the clinical success rate was 85% ,root discount rate of 7% .There was statistical significance between the two groups (P< 0 .05) .Conclusion The loss rate ogf fiber post‐retained restoration is higher than the metal post‐retained restorations ,but the root discount rate is low ,incidence of periodontal and periapical tissue similar in the two groups can be routinely used clinically instead of metal post‐retained restoration .
