Objectives: To compare the effectiveness of different solutions - Sodium Hypochlorite 3% (NaOCl), Ethylene Diamin TetraAcetic Acid 17% (EDTA) and Citric Acid 10% (CA) - in removal of Calcium Hydroxide powder mixed with 2% Chlorhexidine gel (CH/CHX) and detection of precipitate. Materials and Methods: 45 single root teeth, 3 groups (n = 15), inserted in a silicone base, were instrumented with ProTaper Universal® files (Dentsply Sirona, Switzerland) up to F3 and divided in halves with a microtome. Two standardized grooves (coronal and apical) were filled with CH/CHX and, for their removal, NaOCl or EDTA or CA activated with E1- Irrisonic Helse Ultrasonic® tip (Helse, São Paulo, Brazil) were used. The grooves were photographed before and after application of CH/CHX. The remaining CH/CHX was evaluated using a scoring system (4 levels). Data were statistically analyzed using the Kruskal-Wallis test and the U-Mann-Whitney test with Bonferroni correction (p AID - 857832
