Removal Efficiency and Effectiveness of Four Different Fiber Posts Using Five Different Drill Systems in Multirooted...

Area of Science:

• Dental Materials Science
• Endodontics
• Prosthodontics

Background:

• Fiber posts (FPs) are widely used in endodontically treated teeth.
• Effective and efficient removal of FPs is crucial for retreatment and managing complications.

Purpose of the Study:

• To compare the effectiveness and efficiency of different post removal systems.
• To evaluate the performance of various drill systems on different types of fiber posts.

Main Methods:

• 200 maxillary first molars were root canal treated and prepared for posts.
• Four types of fiber posts (Radix FP, Reforpost Glass Fiber, Hi-Rem Endodontic Post, D.T. Light-Post Illusion X-RO) were used.
• Five post removal drill systems (PD-25-1.1 Drill, GC FP Drill, EasyPost Precision Drill, Reaccess Carbide Double Taper Kit, H-Endodontic Drill) were tested.

Main Results:

• Significant differences in efficiency and effectiveness were found among fiber post types and drill systems (p=0.00).
• The Re-access Carbide Double Taper Kit and PD-25-1.1 Drill showed the shortest mean removal times.
• The Reforpost Glass Fiber with GC FP Drill achieved the highest effectiveness score, while Hi-Rem post with Re-access Carbide Double Taper Kit had the lowest.

Conclusions:

• The Re-access Carbide Double Taper Kit exhibited superior effectiveness and efficiency in fiber post removal.
• Hi-Rem posts demonstrated the best retrieval results among the tested fiber posts.
• Knowledge of optimal tools and techniques can minimize complications during post removal.
