Shaping properties and outcomes of nickel-titanium rotary and reciprocation systems using micro-computed tomography: a systematic review

Conclusions: The use of the same system in rotary or reciprocation motions and reciprocating single file systems have comparable transportation and centering ability. No difference was observed between rotary and reciprocation systems/motions in surface area and volume of the canal changes. Untouched canal walls and accumulation of debris remained controversial. No relationship was found between kinematics of instrumentation and the formation of dentinal cracks.
