ABSTRACT:
Aim: The goal of the current study is to compare the amount of remaining debris on the walls of the root canal of primary anterior teeth following instrumentation with a single NiTi rotary file system (Kedo-S-Square) and manual Stainless-steel files.
Methodology: This study was carried out as an in-vitro study, on twenty extracted primary anterior teeth. Teeth were divided into two groups randomly; Group I: Manual H-files, Group II: Kedo-S Square rotary files. After preparation of the root canal, longitudinal grooves were prepared on the roots and teeth were sectioned into two halves then processed to be evaluated at cervical, middle and apical thirds under SEM. Scores were given based on the amount of debris and data were collected and analyzed statistically.
Results: In terms of cleaning efficiency, the debris originating at the apical third using the rotary file system was slightly higher than manual technique; however, the result wasn't statistically significant (P> 0.05).
Conclusion: Single pediatric rotary file Kedo-S-square can be utilized as an efficient and faster replacement to manual H-Files in primary anterior teeth.
