“…This came in agreement with Surakanti et al (2014) (10) , who stated that the same design "offset" with different kinematics "rotation, reciprocation" may lead to different outcomes. While these findings were in disagree with Çiçek et al (2016) (36) and Costa et al (2018) (37) who reported more extruded debris associated with the PTN when 1068 compared to the reciprocating single file systems. These inconsistent previous findings could be due to differences design of the instrument, and teeth used.…”

To evaluate the amount of apically extruded debris produced byWaveOne Gold (WOG) and ProTaper Next (PTN) after using mechanical or manual glide path techniques. Methodology: Forty freshly extracted human permanent mandibular first molars were collected and randomly assigned into one of the two main groups (I&II) (n=20 for each group) according to the instrumentation techniques used using either the WOG or the PTN, then each group was randomly subdivided into two subgroups (A&B) (n=10 for each subgroup) according to the type of instrument used to create the glide path using either the PathFiles (PF) or the K-Files (KF). During instrumentation, the apically extruded debris (AED) was collected into pre-weighed Eppendorf tubes. Then tubes were incubated at 70° C for 5 days. The net weight of the apically extruded debris was calculated in gram by subtracting the pre-weight of the empty tubes from the post-weight. The data were statistically analyzed. Results: Using the WOG/KF was statistically significantly associated with the highest amount of the AED followed by the PTN/KF and WOG/PF with no significant difference between them while the PTN/PF was statistically significantly associated with lowest amount of the AED. Conclusions: Although all systems caused apical extrusion of debris, using the multi-file continuous rotary system with mechanical glide path files could be considered as a promising and reliable approach to prepare the root canal with less amount of debris extruded apically.

“…Reciproc instruments are characterized by an extra space between the canal walls and the instrument, which allows more debris collection and facilitates easier removal capabil ity (14) . In accordance with our results Cicek et al (15) found no significant difference between Twisted File and ProTaper. In contrary Burkelin et al (16) reported that Reciproc extruded more debris than ProTaper, the difference may be related to the type of motion used during instrumentation.…”

Aim:This study was conducted to evaluate and compare the amount of apically extruded debris and canal wall cleanliness using different Ni-Ti instruments (ProTaper file F2, Twisted File 25 and Reciproc R 25) used in continuous rotation and reciprocating motion, in round and oval root canals. Materials and Methods: One hundred twenty extracted single rooted teeth were divided into two groups according to the cross section; 60 round and 60 oval cross section. Each group was subdivided into three subgroups according to the file system (20 ProTaper, 20 Twisted File and 20 Reciproc). Each subgroup was further divided into two divisions according to the motion used (10 rotation and 10 reciprocation). Teeth were mounted in glass vials through holes in the rubber stoppers. The glass vials were weighed before instrumentation. Root canal preparation was performed according to its assigned system according to the manufacturer's instructions, and sterile water was used as root canal irrigant. After instrumentation, the amount of apically extruded debris was evaluated by weighing the samples on the microbalance. Thereafter, roots were longitudinally divided for evaluation of smear layer by Scanning Electron Microscope (SEM). The data were tabulated and subjected to statistical analysis. Results: Reciprocating motion extruded more debris than continuous rotation motion. SEM examination revealed greater amount of smear layer in the oval cross section canal than round cross section canal. Conclusion: All instrumentation techniques and motions were associated with extruded debris. All instrumentation techniques and motions were not capable of completely preparing oval canals.Root canal preparation using either manual or rotary instruments always causes the formation of pulpal debris, smear layer and smear plugs which cover the whole root canal surface. One of the challenges

“…Irrespective of the system used, all promote extrusion of microorganisms, contaminated dentin, irrigant solutions, and remaining pulp tissue beyond the apical foramen, causing postoperative complications, such as periapical inflammation and pain . However, studies have pointed out that there are differences in the amount of debris extruded, depending on the system used for root canal preparation …”

Aim: The aim of the present study was to evaluate the effect of large instrument use on the shaping ability and apical debris extrusion of rotary and reciprocating systems in oval-shaped root canals.Methods: Forty-five mandibular premolars, with an 18-mm long, oval-shaped single canal, and apical diameter ranging from 300 to 350 μm, were separated into three groups (n=15), according to the system used: ProTaper Universal group, F5 (0.50/0.05);ProTaper Next (PTN group), X5 (0.50/0.06); and Reciproc (RC group), R50 (0.50/0.05). Cone-beam computed tomography was performed before and after preparation toanalyze apical transportation (AT), centering ability (CA), and change in root canal diameter (CRCD). For evaluating apical debris extrusion, the roots were coupled to preweighed glass receptacles to collect the extruded debris during preparation.Results: All systems promoted AT and apical debris extrusion; the latter was higher for the PTN group (P<.05). No system presented perfect CA. The RC group demonstrated the largest CRCD (P<.05). Conclusions:As consequences of their use, the large instruments promoted undesirable AT and debris extrusion, irrespective of the system used to perform root canal preparation. Moreover, no system was able to remain perfectly centralized within the root canal. K E Y W O R D Sendodontic, large instrument, mandibular premolar, root canal preparation, tomography
