“…Reciprocating files works by back and forth motion that reduces the number of endodontic mishaps through instrument separation, thereby improving the safety of the shaping procedures [20]. Prabhakar et al, stated that the reciprocating single file system were faster and safer for canal preparation as the reciprocating motion does not over engage the dentin and reaches the working length faster than rotational motion [21].…”

Objective: Pulpectomy is the conservative treatment approach that retains and preserves the primary tooth in the dental arch in its normal function and non-pathologic state until its exfoliation. Over the years, pulpectomy has been performed using various instrumentation techniques. The aim of this study was to compare the quality of root filing and instrumentation time using Kedo-S files, Reciprocating files and K-files in primary teeth. Material And Methods: A randomized clinical trial was performed on 45 primary molars equally distributed for instrumentation with Kedo-S files, reciprocating files and K-Files. Immediate post-operative digital radiographs were taken to evaluate the quality of root filing and root canal instrumentation time was also recorded. Results: Mean instrumentation time with Kedo-S was 75.6 seconds, reciprocating file was 190.6 seconds and K-file was 95.4 seconds. Highest optimal fill was obtained with Kedo-S file group, highest overfill was obtained with Kedo-S group and highest under fill was obtained with reciprocating file group. Conclusion: Kedo-S rotary system provides better quality of root canal filling in minimum instrumentation time.KEYWORDS Pulpectomy; Primary teeth; Root canal filling; Rotary files.

“…Only one study reported longer times for instrumentation with rotary systems compared to the manual, in which he considered it as a matter of operator's experience .

“…9 Regarding the risk of canal transportation, less effect was found using a reciprocating system compared to a continuous rotary system in primary teeth. 29 Regarding anatomic features, root canals of primary maxillary central incisors are flat, ribbon-shaped, whereas the rotary instruments have a spherical shape with a taper descending to the apex. Therefore, a percentage of noninstrumented areas will always be expected when using these instruments, as verified for permanent root canals.…”

Summary Background Efficient endodontic instrumentation of primary teeth is a challenge for paediatric dentists. Aim To evaluate biomechanical outcomes of endodontic instrumentation with a reciprocating system in a polymer‐prototyped primary maxillary central incisor. Design The specimen was systematically instrumented and micro‐CT scanned before and after each file. The amount of debris, percentage of non‐instrumented areas, removed dentin volume, and lower dentin thickness at specific points along the root canal were analyzed. Results A 10% increase in removed dentin volume was observed when R40 was compared to R25 (14.5% vs 4.2%). When comparing R50 with R40, this increase was only 3.4% (17.9% vs 14.5%). In the root cervical third, there was substantial reduction in dentin thickness with R50 (48.8%), followed by R40 (39.5%) and R25 (18.6%). There was no difference between R25 and R40 in the removal of dentin at the apical third (15.8%), while R50 resulted in 39.8% reduction in dentin thickness. Percentage of non‐instrumented areas were the same for all files. Accumulated debris with R40 and R50 was the same (0.19 mm³) while for R25 was 0.11 mm³. Conclusions The Reciproc® system was effective for instrumentation of a prototyped primary maxillary central incisor. The most suitable file for apical preparation was R40.

“…However, the physics behind reciprocating motion is based on the “law of action and reaction,” which results in a balanced force during canal instrumentation, as theorized by Prabhakar et al . [ 4 ] The first study experimenting with an alternating movement was that of Yared in 2008, which used the ProTaper F2 instrument (Dentsply/Maillefer) in a reciprocating movement. [ 13 ] The reciprocating movement minimizes torsional and flexural stresses, increases the canal centering ability, and reduces the taper lock of the instrument within the canal.…”

Aim and Objective:The aim of this study is to evaluate and compare the effect of one shape, Neolix rotary single-file systems and WaveOne, Reciproc reciprocating single-file systems on pericervical dentin (PCD) using cone-beam computed tomography (CBCT).Materials and Methods:A total of 40 freshly extracted mandibular premolars were collected and divided into two groups, namely, Group A – Rotary: A1 – Neolix and A2 – OneShape and Group B – Reciprocating: B1 – WaveOne and B2 – Reciproc. Preoperative scans of each were taken followed by conventional access cavity preparation and working length determination with 10-k file. Instrumentation of the canal was done according to the respective file system, and postinstrumentation CBCT scans of teeth were obtained. 90 μm thick slices were obtained 4 mm apical and coronal to the cementoenamel junction. The PCD thickness was calculated as the shortest distance from the canal outline to the closest adjacent root surface, which was measured in four surfaces, i.e., facial, lingual, mesial, and distal for all the groups in the two obtained scans.Results:There was no significant difference found between rotary single-file systems and reciprocating single-file systems in their effect on PCD, but in Group B2, there was most significant loss of tooth structure in the mesial, lingual, and distal surface (P < 0.05).Conclusion:Reciproc single-file system removes more PCD as compared to other experimental groups, whereas Neolix single file system had the least effect on PCD.
