Fifteen years of engine‐driven nickel–titanium reciprocating instruments, what do we know so far? An umbrella review

Australian Endodontic Journal, Volume 50, Issue 2, Page 409-463, August 2024.
Abstract Numerous systematic reviews (SRs) have produced conflicting findings on engine‐driven nickel–titanium reciprocating instruments (reciprocating instruments) since Yared's seminal study 15 years ago. This umbrella review analysed SRs examining the clinical and laboratory evidence regarding reciprocating instruments for root canal treatment.
