On each half, a defect simulating an internal resorption was fabricated on the middle root canal third using a round bur. One week after insertion of calcium hydroxide paste, the teeth were divided into three groups according to the technique employed: G1-Conventional irrigation; G2-XP Clean and G3-Easy Clean. Each instrument was used in three cycles of 20 seconds, followed by renewal with 2 ml of irrigant. Thereafter, the specimens were analyzed on a stereoscopic magnifying glass to analyze the removal of dressing material.</p> <p><strong>Results:</strong> Similar performance was observed for both methods employed, even though the rates of absence of removal were higher for the group Easy Clean compared to the group XP Clean.</p> <p><strong>Conclusions:</strong> The XP Clean presented better results in removing the calcium hydroxide paste compared to Easy Clean, with statistically significant difference.</p>}, number={2}, journal={Giornale Italiano di Endodonzia}, author={Brunini, Sérgio Henrique Staut and Yamashita, Mariana Suemi and Babolin, Mayara de Oliveira and Tomazinho, Luiz Fernando}, year={2020}, month={Oct.} }
