Abstract
Introduction: Irrigants also play a crucial role in removing debris and smear layer from the root canal walls, in addition to antimicrobial activity which allows for better adhesion and penetration of root canal sealers and obturation materials (1). The most commonly used irrigants in endodontic treatment include sodium hypochlorite, chlorhexidine, and ethylenediaminetetraacetic acid (EDTA) [6]. However, each of these irrigants has its own limitations and potential side effects, such as cytotoxicity, allergic reactions, and dentin erosion (2). Therefore, the search for alternative irrigants that possess better antimicrobial activity and fewer side effects is ongoing in the field of endodontics.
Materials and Methods: The antimicrobial activity of the synthesised nano chitosan with chlorhexidine and Plain Chitosan with Chlorhexidine was evaluated using the agar well diffusion technique. Mueller Hinton agar plates were prepared and sterilised using an autoclave at 121°C for 15- 20 minutes. After sterilisation, the medium was poured on to the surface of sterile Petri plates and allowed to cool to room temperature. The bacterial suspension (E.faecalis) was spread evenly onto the agar plates using sterile cotton swabs. The wells were then filled with different concentrations of nanoparticles and plain chitosan solution. An antibiotic (e.g., Bacteria-Amoxyrite) was used as a standard. The plates were incubated at 37°C for 24 hours and 48 hours for bacterial cultures.
Results: Nanochitosan with chlorhexidine shows higher antimicrobial activity when compared to plain chitosan .Its activity increases with increase in dosage.10μl shows maximum antimicrobial efficacy. Increase in the time period showed increased antimicrobial efficacy. Antimicrobial efficacy at 10μl is comparable to positive control (sodium hypochlorite)
Conclusion: The irrigant nanochitosan with chlorhexidine showed better antibacterial efficacy than sodium hypochlorite and it can be used as an irrigant in endodontics. The several known advantages of this irrigant such as naturally available, non cytotoxic, biocompatible and low cost make it a good replacement of sodium hypochlorite as an irrigant.
