Background: Irrigants were required to eliminate the microbes and debris from the intraradicular space and must have direct contact with the entire root canal wall. Therefore, different irrigation methods have been proposed to deliver the irrigant as close as possible to the remote areas of the root canal. Aim: The aim of the present study is to evaluate the cleaning efficacy of single-beveled needle, side-vented needle, endovac, and endo-irrigator plus in the removal of debris from apical third of root canal by Scanning Electron Microscope. Materials and Methods: Forty single-rooted freshly extracted human permanent mandibular premolars were collected. Root canals were cleaned and instrumented till X2 (25/06) with rotary Protaper Next at working length 1 mm short of the apex. Teeth were randomly divided into four equal groups: Group 1 ( n = 10): Endovac, Group 2 ( n = 10): Endo irrigator plus, Group 3 ( n = 10): Side-vented needle, and Group 4 ( n = 10): Single-beveled needle. Irrigation was done with 5.25% NaOCl, followed by 17% ethylenediaminetetraacetic acid. Samples were sectioned and examined under SEM at apical levels. Statistical Analysis: Analysis of variance followed by Tukey's post hoc test was performed. Results: The level of debris removal efficacy is as follows: Endovac > Endo-irrigator plus > Side-vented needle ~ Single-beveled needle. Conclusion: Endovac showed the maximum number of debris removal and has better cleaning efficacy in the apical areas of the root canal, followed by Endo irrigator plus, Side-vented needle and Single-beveled needle.

A BSTRACT Aim: The aim of this study was to compare the decrease in bacterial population in the root canals with 2.5% sodium hypochlorite (NaOCl) and three irrigation systems: Conventional Needle Irrigation, Passive Ultrasonic Irrigation, and EndoVac Apical Negative Pressure Irrigation system Materials and Methods: Access open was carried out in 48 extracted single-rooted maxillary and mandibular human premolar teeth. The canals were instrumented 1 mm short of apical foramen up to No. 50 size file; irrigated and apical foramen was sealed with cyanoacrylate. The teeth were mounted in plaster and autoclaved for 20 min at 121°C. The plaster blocks containing the teeth were inoculated with Enterococcus faecalis and incubated at 37°C for 24 h. The specimens divided randomly into four groups ( n = 12) depending on the type of irrigation system used: Group 1: Conventional Irrigation Needle, Group 2: Ultrasonic system, Group 3: EndoVac Negative Pressure Irrigation system used with 2.5% NaOCl, and Group 4: Control group, normal saline irrigation. The normal saline is used as control. The samples were collected using 45 size sterile paper points and quantitative bacterial assessment was carried out by seeding each dilution on plates containing brain heart infusion broth. Then, incubated at 37°C for 7 days and colony-forming units were counted. Data obtained were statistically analyzed. Results: Statistically, EndoVac irrigation systems were more effective in reducing the number of bacteria than the other irrigation systems. Conclusion: EndoVac irrigation system was more effective in reducing bacterial numbers in infected root canals than the other two irrigation systems.

“…On the other hand, microleakage of the root canal systems is a complex subject because many variables may influence it, such as root filling techniques, the physical and chemical properties of the sealers used and the smear layer [13]. Success of the smear layer removal depends on the instrumentation techniques employed and irrigation solvents used [14,15]. Sodium hypochlorite solution has been the commonly used irrigant, especially due to its effective antibacterial properties and its excellent action as an organic material solvent [16].…”

Aim: The aim of this ex vivo study, with SEM, was to determine the effects of the smear layer on the root canal systems after different instrumentation technique and irrigation protocol, obturated with carrier based gutta-percha (Soft Core) and AH26 sealer. Materials & Methods: Forty freshly extracted human teeth were used for this study. The teeth were divided into two major groups according to instrumentation technique (Manual and ProFile) and then each major group into four subgroups according to irrigation protocol (Saline solution, 17% EDTA, 5.25% NaOCl). All of the samples were obturated with AH26 and Soft Core Heating Gutta-percha. The evaluation of the objectives was performed using a Scanning Electron Microscope. Result: ProFile instrumentation followed with irrigation of 17% EDTA and 5.25% NaOCl, selaed with AH26 Soft Core Heating Guttapercha provided maximal contact at the S/D interface. The S/D interface had a serrated appearance due to effective penetration of the sealer into the patent dentin tubules. Conclusions: The adhezion of the respective sealer is more successful in cases when smear layer was removed completely.
