Objective: The purpose of this study was to compare the precision of the working length of Root ZX mini, Proper Pixi, Woodpex III and Raypex 6 using VDW C-Pilot No. 15 with Maillefer nickel titanium No. 15 and stainless steel files in mesiovestibular ducts of first lower molars. Materialsand methods: This was an experimental in vitro study, including 35 mesiobuccal canals of lower first molars. The real length of 4 electronic apical locators, Root ZX mini, Proper Pixi, Woodpex III and Raypex6, was determined with a digital Vernier caliper, and electronic measurementswere recorded using stainless steel and nickel titanium files. Results: There were no statistically significant differences between the real and the electronic lengths of the different tools studied (p <0.05). Conclusions: Statistically significant differences were obtained when comparing theprecision of Root ZX mini, Proper Pixi, Woodpex III and Raypex 6 with stainless steel files, while the precision of nickel titanium files was not affected.
