Background: The Wave One NiTi File System and Mtwoare a new generation of NiTi rotary instruments. The present study was conducted to compare efficacy of wave one and Mtwo in removing endotoxins and cultivable bacteria from infected root canals. Materials & Methods: The present study was conducted on 72 patients of both genders. A 2-stage access cavity preparation was made in all teeth and teeth were divided into 2 groups of 36 each. IN group I, A size #25 Wave One file with a 0.08 taper (Dentsply Maillefer) was used in a reciprocating motion. In group II, the full length of the canals (single length technique) was prepared according to the manufacturer’s instructions in a gentle in-and-out motion. Results: In group I, endotoxins level was 102 EUs/mL and after treatment was 1.12 EUs/mL. In group II, it was 120 EUs/mL before treatment and 2.46 EUs/mL after treatment. The difference was significant (P< 0.05). In group I, cultivable bacteria (CFUs/mL) before treatment was 1.2X 105 and after treatment was 2.2 X 102. In group II, it was 1.1X 105 CFUs/mL and after treatment 3.21X 102 CFUs/mL.  The difference was significant (P< 0.05). Conclusion: Both systems found equally effective in removing bacteria and endotoxins from infected root canals.
Key words: cultivable bacteria, endotoxins, Wave One file.
