Background: The ability to remove an existing post depends on the type of material that it is fabricated from. The present study was conducted to assess effectiveness of fiber post removal using 3 techniques i.e., with Parapost Fiber removal drill kit, D.T. light removal kit and combination of diamond bur/Peeso reamer. Materials & Methods: A total of 80 extracted non carious, single rooted human teeth with complete root development, mature apex, visible canal space and patent apical foramen were selected for the study. Teeth were randomly divided into groups. Group I: Teeth receiving DT light Fiber Post no 1. Group II: Teeth receiving Parapost Fiber Post no 5. Teeth were then randomly assigned to Subgroup A1: Posts were removed with DT light post removal kit. Subgroup A2: Posts were removed using 1/2 round bur, no. 850 coarse diamond burs and no. 3 and no. 4 Peeso Reamer bur. Subgroup B1: Posts were removed using Parapost Fiber Removal Drill Kit. Subgroup B2: Posts were removed using 1/2 round bur, no. 850 coarse diamond burs and no. 3 and no.4 Peeso Reamer bur. Results: The mean removal time in subgroup A1 was 28.4, in A2 was 28.1, in subgroup B1 was 28.5 and subgroup B2 was 27.4. The difference was significant (P< 0.05). The removal time at cervical third in A1 was 2.3, at A2 was 1.3, at B1 was 2.06 and at B2 was 1.42, at middle third in A1 was 2.14, at A2 was 1.74, at B1 was 2.14 and at B2 was 1.41. At apical third, in A1 was 2.21, in A2 was 1.75, in B1 was 2.14 and in B2 was 1.48. The difference was significant (P< 0.05). Conclusion: Diamond bur/Peeso reamer removal system effectively removed the fiber post. The removal of fiber posts can be achieved in a shorter time and in a more conservative way.
