“…In addition, studies using the SAF system at different working times are available in the literature. These studies are about the amount of deformation of the SAF instrument and the reduction of the number of microorganisms in the root canal (30,31). However, there are no studies in the literature about the effects of various SAF working times on the According to the findings of this study, no significant difference was observed among the groups in the apical thirds (p>0.05).…”

Objective: The aim of this study was to investigate the effects of two different self-adjusting file (SAF) working times and three different chelating agents on the push-out bond strength of root canal fillings in oval root canals. Materials and Methods: Eighty mandibular premolars were selected and distributed into 8 groups (n=10): 4 min SAF (G1), 4 min SAF + 17% ethylenediaminetetraacetic acid (EDTA) (G2), 4 min SAF + 10% citric acid (CA) (G3), 4 min SAF + 1% peracetic acid (PAA) (G4), 6 min SAF (G5), 6 min SAF + 17% EDTA (G6), 6 min SAF + 10% CA (G7), and 6 min SAF + 1% PAA (G8). The root canals were filled using guttapercha and AH Plus root canal sealer, and the teeth were prepared for the push-out assessments using 1.0 mm thick root slices. Loading was performed with a universal testing machine at a speed of 0.5 mm/min; and then, collected data were analyzed statistically (α=0.05). Results: While the different chelating agents significantly affected the push-out bond strength of the root canal filling (p<0.05), the different SAF working times did not (p>0.05). There were no significant differences among the groups in the apical and middle thirds of the roots (p>0.05). In the coronal thirds, G6 and G8 indicated significantly greater bond strength values than G1 and G5 (p<0.05). Conclusion: According to the results, the 4 and 6 min SAF working times did not affect the bond strength of the root canal filling. PAA and EDTA can be recommended for root canal irrigation after SAF usage.

“…According to a recent report by Akçay et al . (), the deformation of the SAF in simulated curved metallic root canals never resulted in complete fracture of the file and never left a part of it inside the canal. This last finding was also confirmed in the present study, despite the difference in the experimental design.…”

“…This finding is in apparent disagreement with the findings of Akçay et al . () who reported that the coronal part of the SAF was deforming more frequently. Such controversy can be attributed to the differences in the design of the two studies.…”

“…On the other hand, in the Akçay et al . () study, the file was operated in a curved metal canal, the dimensions of which were larger than those of the relaxed SAF. In such conditions, the SAF was likely to rotate in the curved canal as the clutch mechanism in the RDT3 handpiece head would not be activated to stop the rotation.…”
