Abstract

Background: Magnesium oxide (MgO) nanoparticles due to their antimicrobial properties and ability to survive under harsh conditions have become an area of interest in the field of biomedical sciences. The aim of the study was to evaluate antimicrobial efficacy of Nano-MgO in the elimination of endodontic pathogen .
Materials and Methods: Minimum inhibitory concentration (MIC) of Nano-MgO and sodium hypochlorite against was calculated using broth dilution method. The antibacterial efficacy of Nano-MgO in elimination of the pathogens was seen using an ex-vivo model of decoronated teeth which were experimentally infected. The antibiofilm activity of the tested antimicrobial agents on biofilms was determined quantitatively by counting the colonies on Mueller-Hinton agar plates and by evaluation under scanning electron microscopy (SEM). The data analysis was done using one way ANOVA and the intergroup comparison by student –t test.
Results: MIC concentration of Nano-MgO was observed at 10mg/ml for . Mean values of colony forming unit (CFU) count was maximum for normal saline, followed by Nano-MgO and sodium hypochlorite with a significant difference between all the three groups.
Conclusion: The results of the study reveal that Nano-MgO has the potential to be used as an alternative irrigating solution in endodontic therapy.
