Objective: To investigate the effective way to restore the flat root canal by comparing the clinical success rates of the plastic fiber post and the prefibroblasts pile fiber post. Methods: One hundred and one premolars with the single root canal,which have been completely treated with RCT,were treated with post-core crown restoration. The prefibroblasts pile fiber post was used in 52 cases( Group A),and the Ever Stick plastic fiber post was applied in the remaining 49 cases( Group B). The clinical effects of two groups were compared with 6,12,24 months follow-up. Results: The success rates of the Group A were 98. 08% after 6 months treatment,88% after 12 months,and 73. 33% after 24 months,respectively. There was statistical difference between the success rates after 6 months treatment and after 2 years( P 0. 001). Furthermore,the success rate after 12 months treatment showed no significant differences with other monitoring time intervals. The success rates of Group B were 100% after 6 months treatment,95. 8% after 12 months,90. 91% after 24 months,respectively. The success rates showed no significant differences in the three monitoring time intervals. However,the success rate of Group B was significantly higher than Group A after 24 months treatment( P 0. 05). Conclusion: Ever Stick plastic fiber post showed bettereffect in 24 months.
