Analysis of working time of the reciprocating single file instrumentation: WaveOne and Reciproc. Rev. Assoc. Paul. Cir. Dent. [online]. 2012, vol.66, n.2, pp. 120-125. ISSN 0004-5276.

The aim of this study was to analyze the working time for endodontic instrumentation using the reciprocating single file system: WaveOne and Reciproc. Twenty curved simulated resin root canals were used, where 10 samples were shaped using WaveOne system and 10 samples using Reciproc. The working time with and without irrigation and exploration time was recorded. The thirds were also individually considered. The data were analyzed by Mann-Whitney, Kuskal-Wallis and Student-Newman-Kels tests (p=0.05). The results showed signifficant difference between the groups on both situations (with and without irrigation and exploration time), where time needed for instrumentation of medium and apical thirds was shorter for Reciproc group than for WaveOne group. It can conclude that both systems are fast on the endodontic instrumentation, but the Reciproc system is faster than the WaveOne system.
