Context:
Pulpectomy preserves primary teeth for function, esthetics, and permanent dentition space maintenance. Root canal preparation risks errors like canal transportation (CT); cone-beam computed tomography (CBCT) offers precise shaping assessment to optimize pediatric endodontic outcomes.
Aims:
The aim of this study was to compare CT and centering ability of five pediatric rotary file systems in primary molars using CBCT.
Settings And Design:
In vitro study of 90 primary molar root canals, randomized into five groups.
Subjects And Methods:
Systems evaluated Kedo SG Blue, Kedo S Plus, Pro AF Baby Gold, Kedo Nano, and Pedo Flex. Pre- and postinstrumentation CBCT measured canal dimensions at coronal, middle, and apical levels.
Statistical Analysis:
One-way analysis of variance with Tukey's honestly significant difference post hoc test ( P ≤ 0.05).
Results:
Kedo Nano exhibited minimal transportation and superior centering ability across all levels.
Conclusions:
Kedo Nano provides optimal shaping in primary molars, ideal for precise pulpectomy.
