Abstract

Background: When there is a failure of primary root canal treatment there is a need for retreatment. This retreatment mainly aims at the disinfection of the canal space and in attaining hermetic seal of the canals.
Aim: To determine the time taken by three different file systems in retrieval of Gutta Percha from the root canal space.
Materials and Method: 60 freshly extracted single rooted teeth were divided primarily into three groups (n=20) Group A- Neo Endo Retreatment Files, Group B- Solite RS3 and Group C- ProTaper Retreatment Files (PTUR). These were further subdivided into 2 groups with and without magnification. The files were used as specified by the manufacturer.
Results: Neo Endo Retreatment file system was significantly slower in removal of Gutta Percha when compared to PTUR and Solite RS3 with and without Magnification (p=0.000). In the group without magnification there was no significant difference in time required for GP retrieval between Solite RS3 and ProTaper Universal retreatment file system (p= 0.985). With magnification using DOM the ProTaper Universal retreatment file system was significantly faster in removal of Gutta Percha than Solite RS3 (p=0.001).
Conclusion: ProTaper retreatment files and Solite RS3 were significantly faster than Neo Endo Retreatment files when used with and without Magnification. Without magnification both PTUR and Solite RS3 performed similarly but with magnification PTUR was significantly better than other two systems.
