Aim & Objectives: To compare the shaping ability, Canal Transportation and preparation time of four single file systems in J shaped simulated canals.
Introduction: Shaping the root canal is a critical step in endodontic therapy, requiring precise instrumentation and technique. Rotary and reciprocating single-file systems have revolutionized endodontics, offering enhanced efficiency, precision, and reduced procedural errors.
Materials and Methods: 40 J shaped simulated canals were selected for the study. Before canal preparation, the canals were stained with black ink and were photographed using a digital camera (Pre-Operative image) at a fixed position. The groups were randomly distributed into four groups (n=10).Group 1: Hyflex EDM file (HEDM), Group 2: One Shape file (OS) Group 3: WaveOne GOLD file (WOG) and Group 4 One RECI file (OR). After canal preparation with the above mentioned files, the canals were stained with red ink and were photographed (Post-Operative Image) from a fixed position. Pre-operative (pre op) and post-operative (post op) images were superimposed using Adobe Photoshop CC imaging software.
Results: In this study, HEDM file revealed a significantly higher canal width at Apical, Middle and Coronal 1/3rd as evaluated against other endodontic file systems (p <0> OS file recorded the least amount of time required for canal preparation which was statistically significant at p <0>
Conclusion: Group 1 (HEDM) resulted in maximum Shaping ability followed by Group 3, Group 2 and Group 4 which was statistically significant at p<0> All files showed a marked tendency to straighten shaped canal. Group 4 (OR) in reciprocating motion showed the minimum canal transportation at Apical one third which was statistically significant at p<0> Group 2 (OS) resulted in least preparation time as compared to Group 4, Group 1 and Group 3 which was statistically significant at p<0>
