“…The results demonstrated that all groups resulted in apically extruded debris during root canal preparation (p<00.001). This finding is consistent with previous studies on apical extrusion and confirms that chemo-mechanical preparation of the root canal system always leads to the extrusion of debris ( 26 , 29 ). Similar to previous research, manual K files showed the highest percentage of apically extruded debris, although the difference was not statistically significant according to the results of this study ( 18 , 19 , 29 ).…”

“…Therefore, the objective of our research was to compare the amount of apically extruded debris and working time among different primary rotary file systems ( 20 ). Among several methods available for measuring apical debris, we employed the method described by Myers and Montgomery, which is widely used in dental literature ( 23 , 26 ). In this study, distilled water was used as a solution to prevent potential crystallization of sodium hypochlorite.…”

Purpose: The objective of this study is to evaluate the amount of apically extruded debris and working time during root canal treatment with three different primary teeth rotary instrument systems. Materials and methods: A total of 80 extracted primary second molar teeth were randomly divided into four groups (n=20) stratified by the instruments used: AF Baby Rotary, Easyinsmile Baby Rotary, Endoart Pedo Gold, and hand files. The apical extrusion of debris was collected then dried in Eppendorf tubes that were pre-weighed with 10–4 precision micro-balance. The incubation period was set as 14 days at 37°C. The dry weight was procured by deducting the preoperative weight from the postoperative weight. The systems’ working time was calculated by chronometer. Mann Whitney U test with Bonferroni correction was used for pairwise comparison following the variance analysis with Kruskal Wallis test. Wilcoxon test was used for intragroup comparison. Results: Although all instruments caused apically extruded debris (p<0.001), there was no statistically significant difference between the groups in debris extrusion. However, the longest working time was found in the manual K files, the Endoart Pedo Gold system had the shortest working time (p<0.001). Conclusion: Our results demonstrate that all instrument systems caused apical extrusion of debris. Furthermore, the rotary instrument systems designed for primary teeth exhibited significantly shorter working time.

Aim: This in-vitro study aimed to evaluate the shaping ability of hand K files, Kedo S, Hyflex, and the Race evo rotary files when used in the biomechanical preparation of primary molars by using CBCT. Materials and methods:One hundred forty extracted human primary mandibular second molars were randomly allocated into 4 groups of 35 each. Group A: Prepared with stainless steel hand files (MANI, Inc.; Tochigi, Japan), group B: Prepared with Kedo S plus pediatric rotary files (Chennai, Tamil Nadu, India), group C: Prepared with Hyflex cm (Colten-Whaledent) rotary files and group D: Prepared with Race Evo (FKG Dentaire SA, La Chaux de Fonds, Switzerland) rotary files. Before starting any procedure, all the samples were scanned using cone-beam CT (Gendex -GXDP-800, Kavo, Dental Charlotte United States). Pre-operative measurements were performed at 3 points at the middle one third of the distal root canals of the primary molars. Postoperative scans were obtained similar to a preoperative manner. The root canal thickness measurements were made at the same level of the preoperative readings.Results: Comparisons were made between the study groups' means. Data were compared using One Way ANOVA test followed by Tukey's Post Hoc test. The findings revealed no significant difference between any of the groups. Conclusion:No differences were noted concerning the shaping ability of the rotary systems used. Thus, all these systems could be used in instrumentation of primary molars.

“…These files working in rotational motions are shorter than rotary file systems manufactured for permanent teeth and have a triangular cross-section. The limited research on pediatric rotary file systems published thus far has reported its use in the shaping and dentin removal of dentin, the taper of preparation, and apical debris extrusion [9][10][11].…”

This study aimed to evaluate the efficacy of intracanal Enterococcus faecalis reduction using pediatric rotary (EndoArt Pedo Kit Blue, EasyInSmile X-Baby and Denco Kids), rotary (ProTaper Next) and reciprocating (WaveOne Gold) file systems through microbiological analyses in primary molars. Seventy-five mandibular primary second molars were selected and divided into five instrumentation groups and a negative control group. After incubation, five roots were used to confirm biofilm formation on the root canals. Before and after instrumentation, bacterial samples were collected. The bacterial load reduction was statistically analyzed by using Kruskall-Wallis and Dunn post hoc tests at a significance level of 0.05. Denco Kids and EndoArt Pedo Kit Blue promoted higher bacterial reduction than EasyInSmile X-Baby systems. There was no difference in bacterial reduction between ProTaper Next rotary file systems and other groups. Among the single-file techniques, instrumentation with the Denco Kids rotary system showed a more significant bacterial load reduction than WaveOne Gold (p < 0.05). All systems used in the study reduced bacterial counts from root canals in primary teeth. Further studies are required to generate more information about the use of pediatric rotary file systems in clinics.
