“…On the other hand, a systematic review investigated remaining dentine thickness (RDT) after pulpectomy in primary molars and compared the hand and rotary instrumentation. Authors concluded that in rotary instrumentation more RDT remains than manual root canal preparation systems according to the majority of studies 30 . Moreover, studies have demonstrated no differences regarding the cleaning efficacy of either system 31–33 .…”

Key Clinical MessageFormulating an effective root canal treatment plan necessitates clinician awareness of the complexities of the root canal system and possible anatomic challenges. The C‐shaped canal variation accompanying the radicular lingual groove makes the lingual dentinal wall so thin that cleaning and shaping of canals require accurate management. This report presents endodontic treatment of a C‐shaped mandibular second molar diagnosed with pulpal necrosis and asymptomatic apical periodontitis, that initial radiographic assessment revealed extremely thin (0.3 mm) width of the lingual wall of the canals prone to perforation. Mechanical preparation was performed through the anti‐curvature technique and basically by chemical irrigation rather than mechanical instrumentation. The C‐shaped isthmus was prepared up to 25/02 rotary system without dentinal defect while maintaining adequate dentin thickness so as to not significantly reduce the strength of the root. Follow‐up radiographs showed normal periodontal ligament and lamina dura indicating significant healing of the periapical lesion.

“…Among the studies that did involve exclusive paediatric rotary files are the ones performed by Nabeeh et al 25 and Mohamed et al 26 Their studies included the Kedo-S file system and concluded that by using rotary Kedo-S files, tooth structure was better preserved, tapering was made more effectively, and instrumentation time was reduced. A systematic review was performed by Nisar et al 27 to compare the residual dentine thickness (RDT) after pulpectomy in primary molars using manual and rotary endodontic files and inferred that rotary instrumentation resulted in greater RDT leading to superior conservation of tooth structure.…”

BackgroundPaediatric rotary file systems have recently been developed for primary teeth use.AimTo study the cleaning efficacies of two paediatric rotary endodontic files, the Prime PedoTM, and the Kedo‐SG BlueTM against the standard H files.DesignThis in vitro study included 54 freshly extracted primary molars, which were randomised into three groups (n = 18 each) and were prepared using either Kedo‐SG BlueTM, Prime PedoTM or hand H files after injecting methylene blue dye into the canals. Pre‐ and post‐operative cone beam computerised tomography (CBCT) was performed to assess change in root canal volumes. Methylene blue dye removal from canals was assessed using stereomicroscopy, and canal cleanliness was examined by scanning electron microscopy (SEM).ResultsBoth Prime PedoTM and Kedo‐SG BlueTM files reduced significantly less dentine when compared with conventional hand filing with Prime PedoTM removing the least amount of dentine. No significant difference was found in median SEM scores among the groups in the cervical, middle and apical thirds of the roots. Stereomicroscopic assessment of root canal cleanliness using dye removal technique shows a statistically significant difference existing between Kedo‐SG BlueTM and hand H files groups.ConclusionPrime PedoTM removed the least amount of dentine. Kedo‐SG BlueTM performed significantly better than conventional hand filing with H files when the root canal cleanliness was assessed.

Background: Postoperative pain is a common concern in root canal treatment, and the choice of instrumentation technique can significantly impact patient comfort. This study aimed to evaluate the impact of different instrumentation techniques on the incidence of postoperative pain in patients undergoing root canal treatment.Methods: A randomized controlled trial was conducted on 208 patients randomly assigned to four groups: step-back preparation, crown-down preparation, hybrid technique, and conventional instrumentation. Pain intensity was assessed using a verbal rating scale (VRS) at six, 12, 24, 48, and 72 hours postoperatively. Data were analyzed using appropriate statistical methods.Results: The mean pain scores and standard deviations (SDs) were calculated for each instrumentation technique at different time intervals. At six hours, the step-back preparation group reported a mean pain score of 2.3 (SD = 0.8), the crown-down preparation group had a score of 2.8 (SD = 0.9), the hybrid technique group had a score of 2.5 (SD = 0.7), and the conventional instrumentation group had a score of 3.1 (SD = 0.1). The differences in pain scores between the groups were statistically significant at all time intervals (p < 0.05). Conclusion:The choice of instrumentation technique significantly influenced the incidence of postoperative pain in root canal treatment. The step-back preparation technique was associated with lower pain intensity than the crown-down preparation, hybrid technique, and conventional instrumentation. These findings highlight the importance of considering the instrumentation technique to optimize patient comfort during and after root canal treatment.
