Materials and Methods
This study was conducted following the requirements of the Ethic Committee of the National Institute of Science and Technology regarding research involving human tissues. Written informed consent was obtained from each of the patients participating in the study.
Samples for this study were obtained from 30 first and/or second vital mandibular molars with root canal treatment indication, with 2 separate and completely developed roots, without radiographic evidence of periapical pathology and root
Results
Longest distances between WL and maximum irrigant penetration were observed in the Monoject group, with a mean distance of 1.51 ± 0.43 mm, followed by the EndoVac group with a mean distance of 0.42 ± 0.30 mm. Shortest distances were observed in the PUI group with a mean distance of 0.21 ± 0.25 mm (Fig. 3).
Analysis of variance test showed statistically significant differences between groups (P < .001). Tukey honestly significant post hoc tests showed significant statistical differences between
Discussion
The purpose of this study was to compare in vivo the efficacy of the conventional endodontic irrigation syringe, PUI, and a negative pressure system for irrigant delivery to WL of mesial canals of mandibular molars. These canals were selected because of their anatomic characteristics, because most of them are narrow and curved, with a high incidence of isthmuses between them (18).
Sodium hypochlorite was used during the whole preparation procedure to allow the hydrolysis of organic tissue

Previous studies reported that ANP has better irrigant penetration in the main canal in comparison with PUI, SI, and MDA (de Gregorio et al., 2012, 2010; Munoz and Camacho-Cuadra, 2012; S et al., 2019; Spoorthy et al., 2013). It aids in the removal of pulp debris (Nielsen et al., 2007) and ensures adequate disinfection in the apical third (Cohenca et al., 2010).
