Introduction: In endodontics, the use of rotary file systems has made canal preparation easier and safer. There are numerous commercially availassble file systems that work with continuous and reciprocating motions.

Aim: Using "cone beam computed tomography (CBCT)," we examined the "Canal transportation (CT), Canal centering ability (CA), touched (TS), and untouched surfaces (UT)" of dentin after instrumentation in various file systems.

Materials and Procedures: With 100 removed human teeth, we launched an in vitro investigation. We compared continuous rotation ProTaper Gold (PG) and TruNatomy (TN) to reciprocating motion Reciproc blue (RB) and MicroMega One RECI (MR). These were sorted into four groups of equal size. The manufacturer's instructions were followed, and the teeth were prepared as directed. Before and after the preparations, CBCT imaging was performed on all of the teeth at lengths of "8 mm, 5 mm, and 2 mm" from the apex. For the CT, CA, TS, and US following instrumentation, we compared all of the groups pre and after operatively. Using the ANOVA statistical test, the obtained data was analysed for variation, with p0.05 being considered significant.

Results: The CT, CA, TS, and US showed a significant difference at all levels from the apex for all of the groups. We found substantial differences in the CT and CA at all three levels from apex. MR revealed the least amount of CT and CA compared to other methods. At all three levels, MR revealed the least US and the most TS surface. The PG noticed a higher CA.

Conclusion: PG exhibited better CA while MG showed lesser CT, and had better contact with the dentin surface which is essential for the removal of the infected canal surface. Hence it can be recommended for the clinical endodontic application.
