Summary
Complete removal of filling material is essential for proper endodontic retreatment. The aim of this study was to compare, through digital radiography, the effectiveness of the ProTaper Retreatment (PRO), WaveOne Gold (WOG), and Reciproc Blue (REC) systems in removing filling material. Sixty extracted human mandibular premolars were treated and subsequently retreated. Initial endodontic treatment was performed with ProTaper Next system. After obturation, the specimens were retreated using the following systems (n=20): WOG, REC, and PRO. Then, the specimens were analyzed in the mesio-distal (MD) and bucco-lingual (BL) directions using the ImageJ software, considering the residual material as a percentage of the total area of initial obturation. Statistical analysis was performed using ANOVA and Tukey's tests. Although the percentage of residual material in the BL direction was higher than in the MD direction in all groups, there was no differences among groups (p>0.05). So, none of the systems completely removed the filling material, showing similar effectiveness among them.
