Abstract

Purpose: To evaluate and compare the antibacterial effect of 0.5%Metronidazole, 2%Chlorhexidin e, and Normal saline irrigant solutions against Enterococcus Faecalis bacteria in treatment of root canals of primary anterior teeth. Materials and methods: This in-vivo study was carried out on Sixty, anterior, primary teeth of children ranging from three to five years of age. The teeth were equally divided into three groups (20 teeth each), based on the irrigant used during chemo mechanical preparation of the root canals. Result: There was no significance difference between the action of 2.0% Chlorhexidine and 0.5% Metronidazole against Enterococcus faecalis while there was a significant difference when they were compared with the action of normal saline. Conclusion: Both 0.5%Metronidazole and 2.0%Chlorhexidine appeared to be superior as final endodontic irrigants with higher antibacterial efficacy compared to saline.
