The aim of this study is to evaluate the incidence of crack formation while using R eciproc, W ave O ne and T wisted F ile A daptive with and without ethylenediaminetetraacetic acid ( EDTA ) gel. Seventy extracted mandibular premolars were included. The teeth were decoronated until roots of 16 mm were obtained. Samples were distributed into seven groups: group 1, no canal preparation (control); other groups were instrumented so; group 2, Reciproc; group 3, Reciproc + EDTA ; group 4, WaveOne; group 5, WaveOne + EDTA ; group 6, Twisted File Adaptive; group 7, T wisted F ile A daptive + EDTA . Roots were horizontally sectioned from 3, 6 and 9 mm from apex and observed under stereomicroscope. The number and the incidence of cracks were recorded and statistically analysed with chi‐squared and K ruskal– W allis tests. Control group did not reveal any cracks. Crack formation with three novel N i‐ T i instruments was similar. Using EDTA gel did not reduce crack occurrence.
