Abstract:
This study compared the cleaning efficiency of Mtwo, Race and Medin nickel-titanium rotary instruments on 60 mesial roots of mandibular molars.The amount of debris and smear layer in three parts of the root canal walls was evaluated using SEM. The results for remaining debris in the coronal part of root canals were similar, whereas in the middle third, Mtwo instruments achieved significantly better results compared to Race and Medin instruments. In the apical third of the root canals more debris was found by using Race instrument. In general Mtwo instruments had greater success in producing clean canals
