Abstract

ABSTRACT
Background: Although root canal therapy has a high degree of success, it doesn’t always lead to the desired response, and failure may occur.
Aim of the work: Our study was conducted to evaluate the efficiency of ProTaper Retreatment files (PTUR) and Endostar Re retreatment (ERE)system in removal of different root canal filling materials (TotalFill bioceramic sealer and ADseal resin sealer) regarding remaining obturating material on canal walls.
Materials and Methods: The total number of samples was 60 freshly extracted single rooted canines and were randomly divided into into two main groups (I and II) (20 each) according to the type of material used in obturation. Group I: obturated with gutta-percha and total fill sealer, Group II: obturated with gutta-percha and ADseal sealer. Each One of them was categorized into two subgroups: subgroup A and B based on the system use (10 each), Subgroup A: using PTUR and Subgroup B: using ERE. The residual obturating material was evaluated using the digital microscope.
Results: ERE has higher efficiency in removal of obturating material than PTUR system with statistically significant difference. Bioceramic sealer had a significantly higher remaining filling material than resin sealer
Conclusion: Under the circumstances of this study, it can be concluded that : PTUR was fast in retreatment but removed less filling material. ERE was efficient in root canal retreatment. TotalFill sealer was hard to be removed.
Keywords: Different Rotary Ni-Ti Instruments, bioceramic sealer , Root Canal Retreatment.
