Comparative Assessment of Efficiency and Obturation Quality of Kedo-S Plus and Kedo-SH Files During Pulpectomy in Primary Mandibular Molars: An Observational Study

Abstract

Aim: This research aims to evaluate and compare the efficiency and obturation quality of Kedo-S plus and Kedo-SH files

during pulpectomy in deciduous molars.

Materials and Methods: The study involved children aged 4–8 years who required pulpectomy for thirty deciduous lower

molars. They were randomly divided into two groups: Group I used Kedo-SH files, and Group II used Kedo-S Plus files. A

stopwatch recorded the instrumentation time, while Coll and Sadrian criteria assessed the obturation quality. Statistical

analysis was performed with the independent t-test and Chi-square test.

Results: The mean instrumentation time for Group I was 190.1 seconds, significantly longer than Group II's 110.1 seconds,

with a p-value of < 0.0001. However, no statistically significant differences were found in obturation quality between the

two groups.

Conclusion: The Kedo-S Plus group demonstrated reduced instrumentation time compared to the Kedo-SH group while

maintaining comparable obturation quality.
