Objectives:
The
aim of this study was to evaluate dentin crack incidence after root canal instrumentation
using ProTaper Next (PT Next; Dentsply Maillefer, Ballaigues, Switzerland) and
Twisted File Adaptive (TF Adaptive; Sybron Endo, Orange, California, USA) at
different kinematics.

Methods: Sixty
human extracted premolar teeth were selected and divided into 4 main groups.
Group 1: PT Next with continuous rotation (n = 15); Group 2: PT Next with
adaptive motion (n = 15); Group 3: TF Adaptive with continuous rotation (n = 15);
Group 4: TF Adaptive with adaptive motion (n = 15). Fifteen unprepared teeth
were used as control group. Crowns of the teeth were removed and roots were
sectioned at 3, 6, and 9 mm from the apex using a diamond saw. Finally root
dentin pieces were evaluated under stereomicroscope at x25 magnification.
Digital images were evaluated by 2 researchers.

Results: No
cracks were observed in the control group. In groups 2 and 4 no fracture was
observed at the level of 9 mm and similarly in group 4 at 6 mm level. Group 3
showed a significantly higher dentin crack formation followed by Group 1, 2, 4
and control group respectively (
p <
0.039). There was no significant difference between groups at 6 mm and 9 mm
levels (
p = 0.497) except for only 3 mm
level (
p < 0.035).







Conclusions: It
was concluded, both adaptive motion and continuous rotationpromoted dentinal
defect. Adaptive motion produced less dentinal defects all dentin levels but
there was no significant difference.
