Abstract

Background: Among the measures involved in the control of endodontic infection, irrigation is an important factor in the elimination of microorganisms present in the open root canal. It is known that mechanical debridement alone does not result in a complete or permanent reduction of bacteria, therefore antimicrobial agents are used as an aid to mechanical cleaning to completely kill or reduce the number of microorganisms.


Aim:  To investigate the antimicrobial activity of 2.5%, 5.25% sodium hypochlorite and 2.0% chlorhexidine liquid and as the first new study of 60 mg/L silver nanoparticles as an endodontic-irrigating substances against single-species biofilms.


Methods: Biofilms of Enterococcus faecalis, Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans oral sources were produced on a cellulose nitrate membrane placed on agar medium. Membrane filters were transferred to tubes containing 2 mL of fresh broth medium plus neutralizers. Microorganisms were suspended using a vortex, and the inoculum was serially diluted 10-fold. Aliquots of the dilutions were placed on 5% blood agar medium and incubated under appropriate gaseous conditions. Colony forming units were calculated.


Results:  The antimicrobial agents in liquid presentation, especially 5.25% NaOCl, 2% chlorhexidine, and 2% nano-silver liquid killed the tested microorganisms more rapidly with mean rank equal to 1.4, 1.9, and 1.6, respectively. Saline did not inhibit the growth of any of the tested microorganisms, as it was statistically (p < 0.05) different for NaOCl, Nano-silver and chlorhexidine.


Conclusions:  Preferring agents in liquid supply to get rid of biofilm microorganisms, especially 5.25% NaOCl and 60mg/L nanosilver liquid.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
