Purpose: To evaluate the time needed to remove a glass reinforced fiber post versus a titanium post. Methods: 40 extracted anterior teeth were mounted in acrylic blocks then treated endodontically. They were randomly assigned to three groups. The teeth were sectioned horizontally, with the coronal portion removed. The fiber posts were cemented with resin cement and the titanium posts were cemented with glass ionomer or resin cement. The fiber posts were removed by coring them out internally. The titanium posts were removed by creating a trough around the post then vibrating with ultrasonic energy. The teeth were examined visually and radiographically to ensure complete removal of the post and cement. Removal time included the time to make radiographs necessary to ensure complete removal. Results: Post-cement combination significantly affected the median rank of the removal time (Kruskal-Wallis test; H= 12.709; P= 0.002). The mean rank removal time of titanium posts cemented with resin cement were significantly higher than the mean rank of the other two post-cement combinations (Dunn's multiple comparison test; P< 0.05). There was no significant difference between the other two combinations.
