Evaluation Time and Efficacy of Root Canal Rotary Preparation in Primary Teeth: An In-Vitro Study.

Purpose The objective of this study was to evaluate the efficacy, apical debris extrusion, and time of rotary preparation of Baby Fanta files (Fanta Dental, (Shanghai, China) in root canals of primary molars. Materials and methods The study sample consisted of 30 upper secondary molars that were randomly divided into two groups (Baby Fanta - K file, Shanghai, China), each group comprising 15 palatal roots that were prepared, the necessary preparation time was calculated, the apical debris was collected, and they underwent a clearing technique to evaluate the cleaning effectiveness of the files used in this study. Results The results showed that Baby Fanta files were superior to K-file in time of preparation (P-value=0.000) while there were no statistical differences in the effectiveness of cleaning (P-value=0.188) or apical debris extrusion (P-value=0.451). Conclusion Baby Fanta files can be used effectively for the rotary preparation of root canals in primary teeth.
