Transportation and Centering Ability of Kedo-S Pediatric and Mtwo Instruments in Primary Teeth: A Cone-beam Computed Tomography Study

Abstract

BackgroundCleaning and debriding the canals and preserving the shape of the canal without deformation is the primary goals of pulpectomy. Transportation is a critical endodontic iatrogenic fault that could cause a catastrophe. This study evaluated the canal centering ability and canal transportation caused by Kedo-S pediatric and Mtwo instruments, using a cone-beam computed tomography (CBCT).Materials and methodsThis in vitro study was performed on distal roots of 50 primary mandibular first molars. The teeth were scanned using CBCT and randomly divided into two groups. The canals were then prepared using either Kedo-S or Mtwo files (n = 25). The instrumented canals were rescanned. The scanned volumes were sectioned at 2, 4, and 6 mm from cementoenamel junction (CEJ). Canal transportation (CT) and instrument centering ability were estimated and compared in both groups.ResultsThe mean values for two study groups were compared. T -test was used to determine theP value. The Levene's test was used to test the significance between two groups. The two groups showed similar results in terms of transportation and centering ability (P > 0.05).ConclusionKedo-S pediatric and Mtwo instruments demonstrated similar canal centering ability and CTs.How to cite this articleHaridoss S, Rakkesh KM, Swaminathan K.
