“…However, there was no statistically significant difference in bacterial reduction efficacy between the ProTaper Next and WaveOne Gold rotary file systems in this study. This result supports the idea that taper does not affect the shaping and cleaning efficiency of root canals [29]. The WaveOne Gold file system creates higher amounts of debris, constricting the debris laterally in the isthmus and protrusions of the canal walls, resulting in an inability to remove intracanal bacteria [30].…”

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.

“…Results revealed no significant difference between the “K flex” file group (group I) and the rotary systems - Kedo-S (group II) and Pro AF (group III). Results on similar lines were noted by Makarem et al 30 and Gomes et al 31 On the contrary, notable differences between the rotary and manual instrumentation were noted by Ochao-Romero et al 2011, 15 Tyagi et al, 29 Babaji et al, 22 and Shah et al 28 where the obturation time was less with rotary instrumentation.…”

“…Fewer studies have been conducted evaluating the T BMP of hand NiTi “K-Flex” files. A study was conducted by Tyagi et al 29 which compared NiTi “K-Flex” file, “Pro AF” Baby Gold files, and wave one gold reciprocating file. Results showed that the mean T BMP for hand NiTi “K-Flex” files were significantly higher than the other two groups.…”

A bstract Background Single-visit pulpectomy (SVP) protocol with rotary files is highly recommended for the treatment of teeth with irreversible pulpitis. Various rotary endodontic files specially designed for use in the pediatric population are available. The aim is to clinically assess the parameters related to the time required for biomechanical preparation (T BMP ) and quality of filling using a single file system vs a sequential multi-file system in infected primary mandibular molars. Materials and methods A total of 45 infected primary molars were allocated to three groups (two experimental groups ( n = 15) and a control group. The first experimental group was instrumented using NiTi K-Flex files, the second group with a single file rotary system with variably variable (VV) taper, and the third with a sequential multi-file system with constant taper. Biomechanical preparation time was recorded and standardized digital radiograph (RVG) were taken pre- and postinstrumentation. The data recorded was sent for statistical analysis. Conclusion There is a substantial reduction of T BMP in primary molars using single file VV taper and multi-sequential file constant taper. Obturation time for all three file systems was comparable and there were no differences between the three file systems used ( p > 0.05). Multi-sequential file constant taper files showed a higher probability of optimal obturations and minimal voids followed by NiTi “K-Flex” files and single file system but the difference was nonsignificant ( p > 0.05). However, using a rotary in primary teeth results in better canal shape, and less T BMP leading to a better quality of treatment in less 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.
