Comparative evaluation of centering ability of hand, rotary and reciprocating file systems using cone beam computed tomography: An in vitro study


Thamarai Manalan, Jayasree

It is important to develop a continuously tapered form and to maintain the Original shape and position of the apical foramen during instrumentation. The presence of curvatures may cause difficulty in root canal instrumentation. The ability to keep instruments centered is essential to provide a correct enlargement, without excessive weakening of the root structure. Several studies have shown that Ni-Ti instruments remain significantly more centered and demonstrated less canal transportation than stainless steel files. Considerable research has been undertaken to understand the several factors related to an instrument's canal-centering ability. The objective of this study was to evaluate and compare the centering ability of conventional Hand K files, Rotary Protaper next and Reciprocating Wave One gold systems using cone beam computed tomography.
