Comparative Evaluation of Cleaning Capacity and Efficiency of Kedo-S Pediatric Rotary Files, Rotary ProTaper, and Hand K Files in Primary Molar Pulpectomy.

Aim And Objective: To assess and compare the cleaning efficacy and instrumentation time of K files, ProTaper, and Kedo-S rotary files in primary molars.

Materials And Methods: India ink was injected into 120 root canals of selected primary molars. The root canals were randomly and equally divided into three groups based on instrumentation technique: group I-K files, group II-ProTaper, and group III-Kedo-S. After instrumentation with respective method, the canals were cleared and observed under a stereomicroscope, the instrumentation time for each root canal was also measured with a stopwatch. Statistical analysis was done with one-way analysis of variance (ANOVA) and Bonferroni.

Result: Kedo-S rotary files performed significantly better cleaning of the canals in the coronal and middle third than ProTaper and K files ( = 0.0001). In the apical third, the difference between the two rotary systems was not significant. The time taken for instrumentation was lowest with Kedo-S followed by ProTaper and K files.

Conclusion: Kedo-S pediatric rotary system showed significantly better cleaning than ProTaper rotary system and K files in cleaning primary molar root canals.

Clinical Relevance: The anatomy and morphology of primary teeth demand a specialized file system that will overcome the shortcomings of conventional biomechanical preparation. Kedo-S files, being exclusive pediatric rotary files, might prove to be a boon in primary canal preparation.
