“…Although there are no studies in the literature analyzing the efficiency of Easy Clean in the removal of root canal dressing, Duque et al () demonstrated the greater capacity of this instrument in removing debris from the area of isthmus than conventional irrigation, irrespective of the third analyzed, corroborating the findings of this study. Moreover, studies have shown similar results between Easy Clean and PUI relative to the capacity for taking the irrigant solution into areas of difficult access (Duque et al, ; Andrade‐Junior, Batista, Marceliano‐Alves, Alves, & Silva, ), as could be observed in the present study. Conversely, Kato et al () obtained significantly better results for Easy Clean in comparison with PUI in removing debris from the apical third.…”

“…This more efficient action of both methods that agitate the irrigant solution compared with that of conventional irrigation occurs by their capacity to produce a high flow of irrigant solution, thus allowing it to penetrate more deeply, also in anatomically complex regions such as the flattened type (Duque et al, ; Capar et al, ).…”

“…Passive ultrasonic irrigation (PUI) has been widely used for optimizing the cleaning and asepsis of root canal systems. Various studies have demonstrated that its use promoted significant improvement in cleaning complex anatomic areas, reducing the remnants of pulp tissue and debris arising from instrumentation (Duque et al, ; Justo et al, ; Vivan et al, ). Moreover, some authors have demonstrated good results when it has been use for removing calcium hydroxide paste (Yücel, Gürel, Güler, & Karabucak, ; Capar, Ozcan, Arslan, Ertas, & Aydinbelge, ).…”

The aim of this study was to evaluate the capacity of conventional irrigation, passive ultrasonic irrigation (PUI), and Easy Clean for removing calcium hydroxide‐based root canal dressing from oval root canals. Thirty mandibular uniradicular incisors with oval canals were used, and subjected to chemical–mechanical preparation with Reciproc R40 instruments. The main canal was filled with a paste based on Ca(OH)2 P.A., iodoform and propylene glycol in the ratio of 3:1:1. The teeth were stored in 100% humidity at a temperature of 37°C for 14 days. Afterwards, the teeth were divided into three groups (n = 10) according to the method of irrigation used (conventional irrigation, PUI, and Easy Clean). The specimens were analyzed by computed microtomography at three time intervals: before placing the root canal dressing, with the root canal dressing in place, and after application of the irrigation methods for removing it. The data were submitted to Kruskal–Wallis and Dunn tests for analyzing the canal as a whole, and Friedman and Dunn for analyzing the root thirds. The results showed that conventional irrigation was less efficient for removing the root canal dressing in comparison with the methods that agitated the irrigant solution (p < .05). When the root canal was analyzed as a whole, Easy Clean, and PUI were similar (p > .05). In analysis of the thirds, Easy Clean was more efficient than conventional irrigation in all the thirds, while PUI showed this behavior only in the cervical third (p < .05). The authors concluded that in oval canals, none of the irrigation methods were capable of removing all the root canal dressing, however, the methods that agitated the irrigant solution were more efficient than conventional irrigation.

Efficacy of sonically, ultrasonically and laser‐activated irrigation in removing a biofilm‐mimicking hydrogel from an isthmus model

Aim To evaluate the efficacy of sonically, ultrasonically and laser‐activated irrigation (LAI) in removing a biofilm‐mimicking hydrogel from the isthmus in a root canal model. Methodology Transparent resin blocks containing two standardized root canals (apical diameter of 0.3 mm, 6% taper, 16 mm long, with a coronal reservoir) connected by an isthmus (0.15 mm wide, 2 mm high) were used as the test model. The isthmus was filled with a hydrogel‐containing dentine debris. The canals were filled with irrigant, and the models were randomly assigned to the following activation groups (n = 20): EndoActivator (EA), Eddy, ultrasonically activated irrigation (UAI) with an Irrisafe 25 mm length, size 25 file and LAI with a 2940 nm Er:YAG‐laser (20 Hz, 50 μs, 20 mJ, PIPS tip at the canal entrance). All protocols were executed for 3 × 20 s. Needle irrigation (NI) with a 27G needle served as the control. Standardized images of the isthmus were taken before and after irrigation, and the amount of removed hydrogel was determined using image analysis software and compared across groups using Welch anova (P ≤ 0.05). Results Hydrogel removal was greatest in the LAI group (90.2%) and was significantly greater than that with UAI, EA and NI (P ≤ 0.014), but not significantly different from Eddy (P = 0.498). Hydrogel removal with Eddy (85.9%) was significantly greater than that with NI and EA (P < 0.05), but not significantly different from UAI (P = 0.07). There was no significant difference between the NI and EA groups (P = 1). Conclusions Laser‐activated irrigation and Eddy resulted in the greatest hydrogel removal and performed better than EA and UAI. The effect of LAI was also not dependent on deep intracanal tip placement.
