Microflora reduction or elimination, during root canal treatment can be achieved by both chemomechanical preparation and intra-canal dressings.1 Although it seems unreasonable to place particular emphasis on any endodontic procedure, chemomechanical preparation may be considered an essential step in root canal disinfection.2 The removal of irritants from the root canal is conducted by means of the mechanical action of instruments and the flow and backflow of the irrigating solution.3 In addition, antibacterial irrigants may significantly help to eliminate bacterial cells from the root canal system.4 With the aim of improving the root dentin cleanness and disinfection, Torabinejad et al developed a new solution, the so-called…show more content…

Zone of inhibition against B.fragilis was shown maximum by Metronidazole, followed by Aztreonam, then by Biopure MTAD and minimum for Normal saline. RESULT- Metronidazole > Aztreonam > Biopure MTAD > Normal Saline.
