Single file reciprocation: A literature review

Root canal preparation with only one nickel-titanium instrument used in reciprocation has been recently introduced. New endodontic systems using this concept, such as Reciproc and WaveOne, have also been developed. The purpose of this review was to identify publications regarding the evaluation, to present comprehensive and critical summaries of current knowledge, and to provide an update of the single file reciprocating concept. Parole chiave: reciprocation, single file, Reciproc, WaveOne
