Introduction: Sodium Hypochlorite (NaOCl) remains gold standard as a result of its antimicrobial effect and tissue dissolution properties, but it has no effect on inorganic portion of smear layer. Thus the combination of NaOCl and EDTA has been proven to have the perfect ability in removal of both organic and inorganic debris. These irrigants when used with conventional syringe irrigation were unable to penetrate the apical portion of the root canal, so new activation devices have come in the market which claims to be effective in delivering the irrigant to the working length. Objective/Aim: This study evaluated and compared the efficacy of recently introduced irrigation activation devices EndoActivator, Passive ultrasonic irrigation and Laser on removal of smear layer from the apical third of instrumented root canal using Scanning electron microscope. Methods: Forty three single rooted teeth were prepared with the help of protaper files and divided into four groups. Group I: EDTA only, Group II: Endoactivator, Group III: Laser, Group IV: Passive Ultrasonic Irrigation (PUI). Three specimens were not treated with any smear layer removal protocol and were immediately sectioned and sent for SEM examination. The remaining 40 samples from 4 groups after treatment with different activation system were also sectioned and sent for SEM examination. The data obtained were statistically analysed using Friedman’s test. Results: All the four groups removed smear layer and the laser showed best smear layer removing capability compared to other groups but was significant only with respect to control and group I (EDTA group without any activation) (p<0.05). Conclusions: Within the limitations of the study, all the activation systems were able to remove the smear layer from the apical third of the root canal with laser showing the best result followed by Endoactivator and then PUI.

Complete removal of infection, rendering root canal free of an organism is the prime aim of endodontic treatment. It cannot be achieved alone by biomechanical preparation due to the complexity of root canal treatment. Therefore the use of intracanal medicament is a must. The antibiotic paste is frequently used intracanal medicament, usually in regenerative cases. Hence the aim of the is to compare different irrigation technique for removal of double antibiotic paste from root canal through a stereomicroscope. 36 single-rooted were standardized to root length of 12mm then instrumented by Protaper rotary file up to size F4. Irrigation was done using sodium hypochlorite in between instrument change. The root canal was dried using paper point and filled by DAP and then randomly allocated to 3 groups(n=12) according to irrigation system used: conventional syringe irrigation (CSI), Passive ultrasonic irrigation(PUI), EndoVac (EV). Roots were then longitudinally sectioned using the diamond disk and studied under a stereomicroscope using a scoring scale. Data were evaluated using one way ANOVA and Tukey test. Among all experimental group CSI was least efficient. PUI and EV showed greater efficiency but no significant difference between PUI and EV, but a significant difference between CSI and PUI, EV (p&lt; 0.05). Use of irrigation activation system results in efficient removal of DAP compared to CSI.

ABSTRACT Aim The aim is to compare the extent of irrigant penetration into root canals up to the working length and in simulated lateral canals after passive ultrasonic irrigation (PUI) and manual dynamic agitation (MDA). Materials and methods Root canals of 36 single-rooted extracted teeth were shaped using rotary files. Irrigation was done with 5.25% sodium hypochlorite and 17% ethylenediaminetetraaceticacid. Teeth were decalcified in 5% nitric acid. Lateral canals were created by inserting 10 K-files and then, the teeth were cleared using methyl salicylate. Samples were randomly divided into three groups of 12 teeth each: Group I — Control, group II — PUI, and group III — MDA. A contrast solution was delivered to the root canals during final irrigation and activation. Specimens were photographed using dental operating microscope, and the mean length of dye penetration was measured. Results Data were analyzed using analysis of variance (ANOVA), Tukey test, and repeated measures ANOVA. Passive ultrasonic irrigation group showed the highest penetration of the irrigant upto the working length followed by MDA. Manual dynamic agitation and PUI groups had equivocal results in lateral canal irrigation. Conclusion Passive ultrasonic irrigation technique is the most effective in delivering the irrigants up to the working length. The effectiveness of PUI and MDA is equivocal in lateral canal irrigation, and hence, MDA can be considered an alternative to PUI, in the case of nonavailability of PUI. Clinical significance The clinician can consider the use of MDA technique for irrigant agitation in root canals as an alternative to PUI, based on the extent of irrigant penetration.
