Background: Irrigating solutions used during root canal treatment act through direct contact with the bacteria targeted and offer long term antibacterial effect. The present study was conducted to assessed antibacterial efficiency of Qmix in root canal disinfection. Materials & Methods: 30 recently extracted mandibular teeth were randomly divided into 3 groups of 10 each. In group I, no irrigation was done. In groups II, teeth were treated with sodium hypochlorite and in group III with Qmix irrigating solutions. After irrigation the teeth were placed in vials, which contained 2 mL of the nutrient broth. Results: Group I yielded 76%, group II 20% and group III 4% colonies of E. Faecalis. The difference was significant (P< 0.05). Conclusion: QMix found to be highly effective in removing smear layer and decreasing level of E. Faecalis as compared to sodium hypochlorite.
