“…This observation was similar to the study completed by Topçuo glu [30], Vivekanandhan et al [48], and Ehsani et al [55]. This result contradicts previously published studies that showed the number of instruments used does not have a direct effect on the debris output [21,50].…”

“…Moreover, the patented variably variable taper design would still allow some amount of debris suspension in the canal space that would eventually be pushed coronally. This is contradicting the results of Uygun et al who concluded that taper design did not influence the debris output [50]. Another reason could be the use of martensitic alloy for the manufacture of these rotary files which allows less debris extrusion compared to conventional austenitic alloy [38].…”

Successful outcome of pulp therapy depends on good chemomechanical preparation of the canals. This is completed with the help of various upcoming rotary and hand files. However, during this preparation, there might be an apical extrusion of the debris which may result in postoperative complications. The aim of this study was to evaluate and compare the number of debris apically extruded during canal preparation using two different pediatric rotary file systems and conventional hand file systems in primary teeth. 60 primary maxillary central incisors that were extracted due to trauma or untreated dental caries with no signs of resorption were taken. Canal preparation was executed using three different file systems: Group A: Group A hand K file system, Group B Kedo S Plus, Group C Kedo SG Blue. For each of these files using the Myers and Montgomery model, the pre- and post-weight of the eppendorf tube was assessed to quantify the number of apical debris. The maximum extrusion of apical debris was noticed with the Hand K-file system. The least debris was noticed in the Kedo S Plus file system. Statistical analysis revealed that there were highly significant differences in apical extrusion and debris when comparing hand files and rotary files and also between the two rotary files used. Apical debris collection is an unavoidable outcome of canal instrumentation. Among the file systems compared, rotary files had lesser extrusion when compared to hand files. Among the rotary files, Kedo S plus showed normal extrusion compared to SG Blue.

Background: Apically extruded debris can be affected by some features of the file systems such as kinematics or metallurgic properties. Aims: This in vitro study aimed to evaluate the effect of movement kinematics (reciprocation or rotation) and heat-treated alloys (C.Wire) on the amount of debris extrusion. Methods: Seventy-two mesiobuccal root canals were assigned into three experimental groups related to the single-file system used (n = 24): two rotational; One Shape (Conventional Ni-Ti), One Curve (C.Wire), and one reciprocating; and One Reci (C.Wire). The file systems were used according to the advisable speed and torque according to the manufacturers’ suggestion. The weight of debris was calculated by subtracting the preweights from postweights of Eppendorf tubes. Kruskall–Wallis and Mann–Whitney U tests were used to analyze the data (P = 0.05). Results: One Shape produced the greatest amount of extruded debris compared with One Curve (P < 0.001) and One Reci (P < 0.001), respectively. No statistical difference was found between One Curve and One Reci concerning amount of apical debris extrusion (P = 0.489). Conclusion: Metallurgical properties of files may affect apical debris extrusion. Alloy type is an important factor in the amount of debris extrusion. File kinematics does not affect apical debris extrusion.
