Aim: To evaluate the foraminal transportation during foraminal enlargement after manual
instrumentation with stainless steel files, preparation with the Mtwo system and Reciproc R25 file.
Methods: Thirty roots were selected, divided in three groups and prepared in accordance with
the different instrumentation systems: Hand Files (HF); Mtwo system (MS); and Reciproc system
(RS). All groups were prepared with the instrumentation level 1 mm beyond the apex.
Photomicrographs were performed using scanning electron microscopy, to record the foraminal
anatomy before and after instrumentation. Data were analyzed using ANOVA followed by Tukey’s
test with a significance level of 5%. Results: The group instrumented with hand files showed
higher foraminal transportation when compared to the Mtwo and Reciproc groups (p<0.05).
Reciproc group showed lower transportation when compared to the Mtwo group (p<0.05).
Conclusions: The stainless steel files caused significant foraminal transportation, while Reciproc
system showed safe apical preparation, with little transportation.
