Objectives. The aim of this study is to evaluate electrolyzed saline, produced from a custom-made chair side apparatus for its cleaning effect on root canal walls.Methods. A chair side apparatus has been designed to produce and dispense electrolytically activated solutions (Electrolyzed saline) for the purpose of root canal irrigation. Two different solutions, one, which is oxidizing in nature, consisting primarily of Chlorine derivatives and another, reducing in nature, consisting primarily of sodium hydroxide, are obtained. A combination of these two solutions was used for root canal irrigation in extracted teeth. Root canals were split and the samples were subjected to Scanning electron microscopic evaluation.Results. Under the conditions of this study, electrolyzed saline significantly cleaned the root canal surfaces well, opening the dentinal tubules and removing the smear layer.Significance. There has been a constant search for the ideal root canal irrigant. Sodium hypochlorite has been vastly used but its toxicity and storage risks are of concern. Electrolyzed saline has been produced from saline and the apparatus prepares and dispenses the solution chair side, obviating storage needs.

Objective: Sodium hypochlorite is shown to be a gold standard intracanal irrigant which has shown to have adequate antimicrobial properties and tissue dissolving properties. The toxicity of these irrigants are seen to be high towards various cells. Natural irrigants provide an alternative to show adequate antimicrobial activity and lesser cytotoxicity potential. The current study proposes a novel intracanal irrigant made from coconut and bromelain extract. Material and Methods: 10grams of sodium hydroxide was dissolved in deionized water followed by which 60ml of coconut oil was added to the warm water bath (40C). The final product was left to dry and crushed manually to powder. This powder was then taken in measured quantity to make a final product containing 20% of coconut and 4% of bromelain. The obtained irrigant was then evaluated against Enterococcus faecalis using Agar well diffusion method. Results: For the natural irrigant, the maximum zone of inhibition was seen highest at 22mm against Enterococcus faecalis and 25mm against Candida Albicans. For 3% sodium hypochlorite when compared against Enterococcus faecalis and Candida Albicans showed a maximum zone of inhibition at 33mm against Enterococcus faecalis and 35mm against Candida Albicans. Conclusion: The study shows that the novel irrigant derived from coconut and bromelain extract has a good antimicrobial efficacy against Enterococcus faecalis and Candida albicans. It can be concluded that it has a potential application as a root canal irrigant for root canal disinfection.

Root Canal Irrigant

During endodontic treatment, eliminating microorganisms from the root canals should be considered with utmost importance. Before filling the canal, every effort should be made to ensure optimal shaping and adequate disinfection of the root canal system. This systematic review aimed to compare the efficacy of herbal agents with sodium hypochlorite (NaOCl) in reducing the microbial load while used as a root canal irrigant. The research question in the present study was to assess “Is there a significant difference in reducing microbial load comparing sodium hypochlorite (NaOCl) and herbal agents.” Electronic databases (PubMed, Scopus, and Web of Science) were searched from their start dates to November 2020 using strict inclusion and exclusion criteria and reviewed following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Only in vitro studies comparing herbal agents with NaOCl regarding antimicrobial efficiency were included. Two reviewers independently assessed the included article. 825 articles were obtained from an electronic database. Twenty papers were included for review of the full text. Eleven papers were excluded because they did not meet the inclusion criteria. Finally, nine articles were included in the systematic review. The present systematic review was at the in vitro level; therefore, the result cannot translate the exact clinical conditions. This systematic review concludes that herbal agents cannot be used as a main irrigant for canal disinfection.

Aim: The aim of this systematic review was to investigate the in vitro antibacterial effect of sodium hypochlorite gel on Enterococcus faecalis during root canal treatment. Methods: An electronic databases (PubMed, ScienceDirect, Google Scholar, CENTRAL, Health Advance) was performed (last updated was 1st April 2019). The reference lists of the included studies were hand-searched. Randomized in vitro studies that compared sodium hypochlorite gel to solution as a root canal irrigant were included. No limitation on publication date. Results: Out of 20741 articles, only two studies with 116 human teeth were included in this review. The studies showed 50% high risk of bias, and 50% medium risk of bias for the included studies. Both sodium hypochlorite gel and solution had some bacterial growth inhibition over E. faecalis. The heterogeneity in methodology of the included studies and the lack of high evidence led to contradictory results. However, sodium hypochlorite solution was better in enhancing the antibacterial effect according to the robust study. Conclusion: There is insufficient reliable evidence about the antibacterial effect of sodium hypochlorite gel on enterococcus faecalis. Although the robust study included in this review revealed that sodium hypochlorite gel is less efficient than the solution as a root canal irrigant, further studies are needed to consider the most effective type, concentration, duration and treatment protocols in enhancing the antibacterial effect of sodium hypochlorite.

Ex Vivo Study

The purpose of this ex vivo study was to determine, in "open" and "closed" systems, whether the design has an influence on the penetration length of sodium hypochlorite mixed with a radiopaque contrast medium, measured in millimeters, when delivered using positive pressure (PP) and using sonic (SI) or passive ultrasonic (PUI) activation. Sixty single-rooted teeth were divided into two groups: open and closed systems (n=30). Root canal shaping was performed to a working length of 17 mm. The samples were divided into three sub-groups (n=10) according to irrigant delivery and activation: PP, and SI or PUI activation. By using radiographs, penetration length was measured, and vapor lock was assessed. For the closed group, the penetration distance means were: PP 15.715 (±0.898) mm, SI 16.299 (±0.738) mm and PUI 16.813 (±0.465) mm, with vapor lock occurring in 53.3% of the specimens. In the open group, penetration to 17 mm occurred in 97.6% of the samples, and no vapor lock occurred. Irrigant penetration and distribution evaluation using open and closed systems provide significantly different results. For closed systems, PUI is the most effective in delivering the irrigant to working length, followed by SI.

Root Canal Irrigant

Objectives: Biopure MTAD™, a new root canal irrigant has shown promising results against the most common resistant microorganism, E. faecalis, in permanent teeth. However, there is lack of studies comparing its antimicrobial effectiveness with NaOCl in primary teeth. The purpose of this study was to compare the in vivo antimicrobial efficacy of NaOCl 2.5% and Biopure MTAD™ against E. faecalis in primary teeth. Study design: Forty non vital single rooted primary maxillary anterior teeth of children aged 4-8 years, were irrigated either with NaOCl 2.5% (n=15), Biopure MTAD™ (n=15) and 0.9% Saline (n=10, control group). Paper point samples were collected at baseline (S1) and after chemomechanical preparation (S2) during the pulpectomy procedure. The presence of E. faecalis in S1 & S2 was evaluated using Real time Polymerase Chain Reaction. Results: Statistical significant difference was found in the antimicrobial efficacy of NaOCl 2.5 % and BioPure MTAD™ when compared to saline (p>0.05). However, no statistical significant difference was found between the efficacies of both the irrigants. Conclusions: NaOCl 2.5% and BioPure MTAD™, both irrigants are equally efficient against E. faecalis in necrotic primary anterior teeth. MTAD is a promising irrigant, however clinical studies are required to establish it as ideal root canal irrigant in clinical practice.
