Abstract: The present study evaluated the amount of apically extruded debris after chemo-mechanical preparation (CMP) associated with passive ultrasonic irrigation (PUI) using four different root canal irrigants, namely, 6% sodium hypochlorite (NaOCl), 2% chlorhexidine gel + saline solution (2% CHXg+SS), 2% chlorhexidine solution (2% CHXs) and SS alone. Sixty mandibular premolars with single straight root canals were selected and randomly assigned into 4 groups (n=15) according to the root canal irrigant used as follows: G1 (PUI + NaOCl), G2 (PUI + CHXg+SS), G3 (PUI+CHXs) and G4 (PUI+SS). Reciproc® R25 files (25/.08) were used during CMP and the debris extruded from each tooth were collected in pre-weighted Eppendorf tubes and dried. The average weight of debris was assessed by using an analytical microbalance. Data were statistically analysed by using ANOVA and post-hoc Tukey’s test (a=0.05). Debris extrusion was observed in all groups, irrespective of the root canal irrigating, with 2% CHXg + SS being associated with lower debris extrusion compared to other irrigants (p<0.05). No significant differences were observed between 6% NaOCl, 2% CHXs and SS. In conclusion, passive ultrasonic irrigation did not completely prevent apically extrusion of debris. PUI performed with 2% chlorhexidine gel + saline solution significantly minimized debris extrusion compared to 6% sodium hypochlorite, chlorhexidine solution and saline solution

Sessenta pré-molares inferiores com canais radiculares únicos e retos foram selecionados e aleatoriamente distribuídos em 4 grupos (n=15) de acordo com o irrigante utilizado: G1 (IUP + NaOCl), G2 (IUP + CLXg + SS), G3 (IUP + CLXs) e G4 (IUP + SS). Limas Reciproc® R25 (25/.08) foram utilizadas durante o PQM e os debris extruídos de cada dente foram coletados em tubos Eppendorf pré-pesados e secos. O peso médio de debris foi avaliado através de microbalança analítica, e os dados foram analisados estatisticamente utilizando ANOVA e teste de Tukey post hoc (a=0.05). Extrusão de debris foi observada em todos os grupos, independente do irrigante. CHXg 2% + SS foram associados a menor extrusão de debris comparado aos demais irrigantes (p<0.05). Não foram observadas diferenças estatisticamente significativas entre NaOCl 6%, CLXs 2% e SS. Concluindo, irrigação ultrassônica passiva não preveniu completamente a extrusão apical de debris, entretanto, IUP realizada com CLXg 2% + SS minimiza significativamente a extrusão de debris comparado ao NaOCl 6%, CLXs 2% e SS
