Basic Research—TechnologyComparison of the Efficiency and Effectiveness of Various Techniques for Removal of Fiber Posts

Materials and Methods
Eighty extracted single-rooted mandibular premolars with similar lengths and widths were used in this study. A diamond disc model trimmer was used to remove the clinical crown 1 mm above the CEJ, perpendicular to the long axis of the root. The prepared teeth were stored in a 0.2% sodium azide solution until used.
The root canals were prepared with .04 ProFile rotary endodontic files (Dentsply/Tulsa Dental Products, Tulsa, OK) and a 2.5% sodium hypochlorite solution. The filling procedures
Results
The means and SEMs for the removal and effectiveness are presented in Fig. 1. Two way ANOVA found a significant interaction, at p ≤ 0.05, for the type of method employed for extraction of each fiber post type for both time and effectiveness. The post hoc Tukey tests indicated that the removal kits required significantly less removal time for each post type (p ≤ 0.05). However, only the group 1 removal kit was significantly more effective in eliminating residual material from the canal walls.
Discussion
It has been suggested that one of the advantages of fiber posts is their ease of retrieval. This investigation determined that removal kits are necessary in order for the clinician to maintain efficiency; however, removal effectiveness results may be better achieved through ultrasonics and diamond burs.
The ParaPost XH was included as a control to determine whether fiber post removal was easier and more effective than removing conventional metal or titanium posts. If diamonds and ultrasonics

2021, Journal of EndodonticsCitation Excerpt :The endodontist’s experience in removing posts from root canal–treated teeth may have contributed to this result. Previous studies investigated the risk of mishaps, including perforation during fiber post removal using different techniques2–5,29,30. In particular, Capar et al30 revealed that fiber post removal with drills does not significantly impact crack propagation, further supporting no occurrence of root fractures found in this study.
