摘要：Objective: Cleaning and shaping of the root canal are important steps in endodontic treatment and may influence the final success of the treatment. The aim of this study was to compare the modeling of the reciprocal instruments Wave One Gold (WOG - Dentisply, Maillefer, Baillagues, Switzerland) and W-File (WF - Shenzlen superfine Technology Co, China) in simulated root canals. Materials and methods: 20 acrylic blocks were used, divided into two groups (n=10): group 1 - WOG; group 2 - WF. Before root canal preparation, the patency of the root canal was checked with a #10 K file. Pre- and postoperative photographic images were created in image processing software (Adobe Photoshop CS5.1) for later overlay and analysis. Statistical analysis was performed using the t-test and Mann Whitney test. Results: With the Wave One Gold instrument, more resin was removed from the outside of the curve at all points examined (p < 0.05). In terms of canal transport, there were significant differences in canal opening (p < 0.05). The Wave One Gold instrument had wider preparations. It was concluded that both the Wave One Gold Instrument and the W-File are safe for use in curved canals and promote good cleaning and shaping, with the WF achieving more conservative preparations.
