Various rotary endodontic instruments were used and studied for the root canal preparation of the primary teeth. Recently, a new venture evolved in the field of pediatric endodontic, which was Kedo S rotary files. These are the files designed exclusively for root canal preparation of the primary teeth.The study aimed to comparatively evaluate the dentin removal and taper of root canal preparation of Hand K files, Rotary Prosper files, and Rotary Kedo S files using cone-beam computed tomography (CBCT) and instrumentation time using stopwatch in primary molars.Sixty-three root canals of maxillary and mandibular primary molars were included in the study. The root canals were randomly assigned to Hand K file (group I), Rotary ProTaper file (group II), and Rotary Kedo S file (group III). Dentin removal and taper of the root canal preparations were evaluated by using CBCT.All the three file systems do not show any statistical significant differences at middle third and apical third but at coronal third, Kedo S removed significantly less amount of dentin as compared to the Hand K file. Taper of the preparations did not show significant differences, even though the rotary files showed good taper in maximum number of root canals.Although not much statistical significant differences were observed in our study, the rotary file system performed slightly better in root canal preparations in primary molars.Seema T, Ahammed H, Parul S, et al.
