“…The study also reveals a statistically significant reduction in the time taken for obturation for both rotary groups, i.e., pediatric and reciprocating file systems. This was consistent as per the study by Babaji et al 24 where the mean obturation time of rotary files (1.4 minutes) was found to be less than hand-files (2.6 minutes). A significant time reduction was seen for obturation of mandibular molars vs maxillary molars.…”

A bstract Background A pulpectomy is regarded as the choice modality of treatment for necrotic teeth. The use of hand files, though popular traditionally as a gold standard, may be challenging due to increased chairside time. Postoperative pain is one of the most common complications of pulpectomy and may be unpleasant for a child/pedodontist. Rotary files were found to reduce instrumentation time, reduce apical extrusion, and in turn reduce pain but there is a lack of studies in primary teeth particularly for pediatric and reciprocating file systems. The increased number of options available today makes it a dilemma for the operator to choose a suitable file system. Aim and objective The study aimed to evaluate and compare the instrumentation time, postoperative pain, and effect on child's behavior among three groups, i.e., hand K-flex files (group I), pediatric rotary files (group II), and reciprocating files (group III). Materials and methods A total of 75 primary molar teeth after meeting inclusion criteria were randomly allocated into three groups. During the procedure, step-wise instrumentation time was recorded using a stopwatch. The child's behavior pre- and postoperatively was assessed by an evaluator. The postoperative pain (up to 1 week) was assessed by a questionnaire. Results The mean age of children taken for the study was 6.03 ± 1.2 years with 46 males and 29 females. The mean biomechanical preparation time was observed to be significantly shorter in the pediatric rotary and reciprocating file groups vs hand K-flex files ( p < 0.001**). The postoperative pain after 6 hours had a mean value of 0.88 + 0.9 for the hand K-flex file group which was significantly higher than both rotary file groups ( p < 0.05*). The pre- and postoperative behavior revealed no significant difference. Conclusion The clinical performance of pediatric and reciprocating files was superior, but the choice of file system did not significantly alter behavior.

Background: Ideal pulpectomy for primary dentition demands fast, simple procedures, with short treatment times and minimal appointments. Recently, exclusive pediatric rotary files are available for use in primary teeth. There is a paucity of literature on the clinical efficacy of pediatric rotary files. Hence, this study was planned to evaluate and compare pediatric rotary files and K-files. Aim: The aim of this study was to evaluate and compare instrumentation time, obturation time, and radiographic quality of obturation using rotary systems (Kedo-S; Pro-AF Baby GOLD files) and manual (K-files) technique in primary molar pulpectomies. Materials and Methods: Forty-five primary mandibular molars from 42 children aged 5–9 were selected. Single-visit pulpectomy was performed after dividing selected teeth into three equal groups: (i) K-files, (ii) Kedo-S files, (iii) Pro-AF Baby GOLD files. Instrumentation and obturation times were recorded during the procedure. Immediate postoperative radiographs were taken and evaluated later for obturation quality by two independent evaluators blinded to the instrumentation technique. The results were then statistically analyzed. Results: Kedo-S (Group II) files required the least instrumentation time followed by Pro-AF (Group III) and K-files (Group I). The superior quality of obturation in lesser time was achieved using Pro-AF files (Group III) followed by Kedo-S (Group II) and K-files (Group I). Conclusion: Pediatric rotary files are efficient alternatives to hand instrumentation and can be considered as the standard of care in pulpectomies of primary teeth.

“…This result is consistent with the findings of prior studies that reported superior obturation quality with the use of a rotary file system in primary teeth, irrespective of the type of rotary file system used. 17,21,[32][33][34] Rotary files debride the uneven walls of primary root canals more effectively and provide dense obturation relative to manual files. 1,2 The HERO Shaper rotary file system produced a slightly higher percentage of optimally filled root canals relative to Kedo-S pediatric rotary file system.…”

Aim: To evaluate and compare the instrumentation time, obturation time, quality of obturation, and clinical and radiological success of pulpectomized teethfollowing root canal preparation of primary molars with rotary and manual file system. Methods: A total of 150 primary molars requiring pulpectomy were selected from children aged four to seven years. These teeth were divided into three groups of 50 teeth each. In Groups 1, 2, and 3, cleaning and shaping were carried out with Kedo-S pediatric rotaryfiles, HERO Shaper rotary files, and manual NiTi K-files, respectively. Obturation was carried out with zinc oxide eugenol cement and an engine-driven Lentulo spiral. The instrumentation and obturation times were recorded. A radiographic assessment of thequality of the root filling was carried out immediately after obturation. Finally, the pulpectomized teeth were clinically and radiographically evaluated over a two-year period. Results: The mean instrumentation times for Groups 1, 2, and 3 were 14.56 ± 2.89 min, 17.93 ± 3.51 min, and 29.00 ± 2.08 min, respectively. The mean obturation times for Groups 1, 2, and 3 were 8.11 ± 1.7 min, 7.93 ± 1.3 min, and 9.64 ± 17.61 min, respectively. The mean difference in the quality of obturation was not statistically significant in primary molars instrumented with Kedo-S pediatricand HERO Shaper rotary file systems (p = 0.16). However, this mean difference was significant when compared between primary molar instrumented with rotary file systems and manual NiTi files (p = <0.001). At two years, the clinical success rate was 100% and the radiological success rates were 95.3%, 97.9%, and 89.5% in Groups 1, 2, and 3, respectively. Conclusions: The rotary file systems took significantly less instrumentation and obturation time than the manual NiTi files. There were no significant differences in obturation quality or success rates after two years.
