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

A bstract

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 post hoc Bonferroni.

Result

Kedo-S rotary files performed significantly better cleaning of the canals in the coronal and middle third than ProTaper and K files ( p = 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.
