Root Canal Irrigant

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.

Aim: The aim of this study was to compare the antimicrobial efficacy of Triple antibiotic paste (TAP), Calcium hydroxide and Acacia nilotica (A. nilotica) (Babbula) against Enterococcus faecalis (E. faecalis), Streptococcus mutans (S. mutans) and Candida albicans (C. albicans) as intracanal medicaments. Materials and methods: The triple antibiotic paste mixture of (metronidazole, ciprofloxacin and minocycline), calcium hydroxide, Acacia nilotica (Babbula) were weighed and mixed with polyethylene glycol and agar well diffusion method was employed to study the antimicrobial efficiency against Enterococcus faecalis, Streptococcus mutans and Candida albicans Results: All the intracanal medicaments showed zone of inhibition against Enterococcus faecalis, Streptococcus mutans and Candida albicans. Among all intracanal medicaments used in the study Triple antibiotic paste produced maximum zone of inhibition followed by Babbula and least by Calcium hydroxide. Conclusions: Triple antibiotic paste showed the best antimicrobial efficacy followed by Babbula and least by Calcium hydroxide against Enterococcus faecalis, Streptococcus mutans and Candida albicans. More phytochemical studies need to be done. Further evaluation of concentrated extracts of Acacia nilotica (Babbula) could yield better results.

Microorganisms, usually from the dental caries, are the main sources of diseases in dental pulp (root canals) and periapical region. Facultative bacteria and fungi have been identified in therapy resistant persistent endodontic infection. The objectives of this study was to evaluate the antimicrobial efficacy of Mineral Tri Oxide Aggregate (MTA) against therapy resistant endodontic microorganisms. The efficacy of MTA was also compared with that of calcium hydroxide. Six standard bacterial stains were used: Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, bacillus subtilis, Candida albicans and Enterococcus faecalis. The agar diffusion method on Muller- Hilton media was employed. The plates containing media were inoculated with the specified bacterial suspensions. Two standard holes were prepared on each microorganism inoculated plate with a copper puncher and one hole was completely filled with MTA & the other with Ca (OH)2 . The plates were then kept at environmental temperature for one hour to ensure prediffusion and then incubated at 370C for 24 hours. After 24 hours, the diameters of inhibition zones were measured. Tests were replicated for thirty times for each sample and mean values were taken. Zone of inhibition as measured for MTA and Ca (OH)2 were statistically analyzed with Student’s t-Test and Post Hoc Games Howell Test and were presented as mean ± SD to compare of efficacy of MTA and calcium hydroxide on different microorganisms. Both MTA and Ca(OH)2 were found to produce zone of inhibition against Staphylococcus aureus (ATCC 25923), Pseudomonas aeruginosa (ATCC 27853), , Bacillus subtilis (BTCC 17 ), and Candida albicans (BTCC 493). MTA showed highest activity against S. aureus and lowest activity against P. aeruginosa which was similar to the activity range of Ca (OH)2 against the mentioned organisms. But both of them failed to produce any activity against E. coli and. E. faecalis. MTA was found to produce a lower efficacy than Ca (OH)2 while comparing the zone of inhibition between them and statistically it was significant. Mineral Tri Oxide Aggregate (MTA) showed antimicrobial efficacy against some therapy resistant microorganisms but it did not show antimicrobial efficacy against Escherichia coli and Enterococcus faecalis. MTA was found to produce a lower antimicrobial efficacy than Ca (OH)2.J Bangladesh Coll Phys Surg 2015; 33(3): 140-145

INTRODUCTION: The technically demanding endodontic treatment sometimes faces failures because of various polymicrobial infections. Common organisms isolated from such infections are Enterococcus faecalis and Candida albicans. Several researches were made with various materials to eradicate such organisms. The study material used here is Lyophilized platelet rich plasma (L-PRP), which has been recently used in dentistry and other medical fields to promote hard and soft tissue regeneration.AIM: The aim of this in vitro study was to evaluate the antimicrobial efficacy of lyophilized platelet lysate (LPL) against microorganisms like Enterococcus Faecalis, Bacillus Subtilis and Candida Albicans.MATERIALS AND METHOD: Discarded blood samples were obtained from blood banks after centrifugation, sterility check and activation. After this, lyophilization of the platelets was carried out. The antimicrobial activity of this freeze dried powder was evaluated by the minimum inhibitory concentration method and then by the Agar disk diffusion method.RESULTS: Lyophilized platelet lysate (LPL) inhibited the growth of Enterococcus faecalis, Bacillus subtilis and Candida albicans which is commonly associated with failed root canal treatment.CONCLUSION: LPL has the potential to be effective against the organisms which causes failure of root canal treatment. This can be of a valuable property in tissue engineering.

Introduction: Candida albicans and Enterococcus faecalis are the most predominant microorganisms found in the canals of failed root canal treated teeth. Thorough debridement of an infected root canal and complete elimination of microorganisms are objectives of effective endodontic therapy. For thousands of years, humans have used herbs as the primary means to sort out health issues and illnesses. Not all herbs have shown to provide scientific evidence as medicine to illness. Neem is a Botanical herb that is truly remarkable with its scientific value, a tropical evergreen native to India. Although different agents have been suggested as root canal irrigants, sodium hypochlorite and EDTA are the most popularly used. Aim: To compare the antimicrobial efficacy of commercially available irrigants, 17% EDTA and a herbal product, neem leaf extract compared with 3% sodium hypochlorite as a control against Enterococcus faecalis and Candida albicans. Materials and Methods: The antimicrobial activity was determined using the agar well diffusion method. Freshly prepared neem leaf extracts, 17% EDTA, 3% Sodium hypochloriteStandard strain of E. Faecalis and C. Albicans were used in this study. These isolates were subcultured on to Brain heart infusion agar (BHI agar) and HI-chrome candidal differential media respectively. The agar well diffusion test was performed in brain heart infusion media and broth. The plates were incubated at 37°C for 24 hours and the zone of inhibition was recorded and analyzed statistically. Results: Zones of inhibition were present with Neem leaf extract suggestive of antimicrobial properties. Zones of inhibition were greater with Neem extract than 17% EDTA. Hence, further research should be directed towards the use of this herbal extract as an irrigant clinically with endodontic therapy. Conclusion: Within the limitation of this study, it was found that neem leaf extract had a significant antimicrobial effect against E. Faecalis and C. Albicans compared to EDTA and Sodium Hypochlorite. Since the study is a qualitative analysis, further testing needs to be done to final quantitative analysis of the antimicrobial activity of neem leaf extract.
