Background: Pediatric rotary file systems were developed to solve manual file limitations. With many systems available, it may be tricky to select the most appropriate one.
Aim: to assess & compare Kedo-S Square, Fanta-AF™-Baby rotary files with manual K-file concerning removed dentin amount, canal transportation, centric ability & root canal taper using CBCT in primary anterior teeth.
Design: Extracted Seventy-five upper primary anterior teeth with intact 2/3 root length were collected and divided into three groups based on root canal instrumentation, group-I: prepared using K-file, group-II: prepared using Kedo-S Square, and group-III: prepared using Fanta AF™ Baby file. The teeth were imaged with CBCT before & following canal instrumentation. Then, the removed dentin amount was calculated at each root-canal level. The Kruskal-Wallis test was utilized to statistically analyze study data.
Result: The difference among the three groups was highly statistically significant at cervical & apical thirds concerning dentin thickness changes on both mesial & distal sides following canal preparation with the least removed dentin in the Kedo-S Square group(P < 0.0001). Regarding transportation & centering ability, a non-significant difference between the three groups was found. 80% of the Fanta AF™ Baby group had good-tapered preparation compared to the Kedo-S Square (72%) and K-file (40%) groups(P < 0.05).
Conclusion: Kedo-S Square was preferable to Fanta-AF-Baby & manual K-files in primary root canal preparation.

A 4.5-year-old female child presented to the Department of Pediatric Dentistry with the chief complaints of sharp, localized pain in her lower left and right back teeth persisting for a week, indicative of irreversible pulpitis in teeth 74, 75, and 85. A single-visit pulpectomy was planned for all affected teeth, followed by full coronal restoration in two separate visits.

Introduction: The success of primary teeth pulpectomy is strongly reliant on instrumentation techniques and their impact on obturation quality & postoperative pain. Recently, pediatric rotary file systems have been implemented.
Aim: to compare two pediatric rotary file systems (Kedo-S-Square & Fanta AF™ Baby) with manual K-files concerning obturation quality, instrumentation time, and postoperative pain in root canal preparation of primary molars using cone beam computed tomography (CBCT).

Purpose: To evaluate and compare the clinical and radiographic success of Kedo-S pediatric rotary files vs manual K-Files for pulpectomy in primary mandibular molars.
Materials And Methods: A sample of 30 primary mandibular molars with irreversible pulpitis was taken per group. The groups were divided as below mentioned-group I ( = 30) was treated using the Kedo-S file system.

Background: The complex root canal anatomy of primary root canals is considered to be most challenging. The quality of the root canal preparation plays a significant role in the success of endodontic treatment. Now, there are very few root canal instruments that are capable of cleaning the canal three dimensionally.
