The aim of this study was to evaluate and compare the antibacterial effect of 0.5% metronidazole, 2% chlorhexidine, and normal saline irrigant solutions against Enterococcus faecalis bacteria in the treatment of root canals of primary anterior teeth. Materials and methods: This study was carried out on sixty nonvital primary anterior teeth of Egyptian children diagnosed with ECC. These teeth were classified equally into three groups according to irrigation materials. A fresh sample was collected from each root canal after access opening before and 3 days after irrigation with the help of a paper point. The number of organisms (E. faecalis) before and after irrigation was compared for each group. Results: The bacterial count of E. faecalis was decreased in all groups however, these differences were statistically insignificant where (p <0.05). Conclusion: Both 0.5% metronidazole and 2.0% chlorhexidine appeared to be superior against E. faecalis bacteria as endodontic irrigants in pulpectomy anterior primary teeth with higher antibacterial efficacy compared to saline. Clinical significance: The success of endodontic treatment depends on the removal of microbes, from the root canals and avoidance of reinfection thus; this study provides an insight on the effects of different irrigant solutions to further help dental practitioners in the endodontic management of primary dentition.
