Abstract: Root end preparation was performed in the apical third of 20 endodontically treated extracted human teeth using high speed, low speed, straight surgical low speed handpieces and ultrasonic machine. The surface properties of the cut root surface was evaluated using a scanning electron microscope (SEM). In addition, the degree of superficial debris and those retained in the cavity of the retropreparation was also examined. Results showed that the smoothest cut surface with minimal debris was produced by #169 plain tapered fissure bur on both high and low speed handpieces. The ultrasonic tip disturbs the gutta-percha filling. Frequent and continuous irrigation is better used during the cutting procedure to remove a greater amount of debris.
