AbstractRoot canal preparation may be the most technique-sensitive and labor-intensive procedure in endodontic therapy. Many automated handpieces and machine-driven devices have been marketed to expedite this procedure. Excalibur is one such handpiece. The purpose of this study was to compare the Excalibur handpiece with traditional K-files for their effectiveness in shaping curved root canals. A total of 24 standardized canals in extracted human mandibular molars were randomly divided into two groups. They were instrumented either with Excalibur according to the manufacturer's instructions or manually using the step-down technique. The cross-sectional shapes of the root canal at the apical, midroot, and coronal levels were digitized before and after instrumentation. Image analyzer software was used to compare the images. The results showed that the methods removed similar amount of dentin at all three levels. Although the Excalibur handpiece had a slight tendency to straighten the canal more than hand instrumentation, the difference was not significant. Strip-perforation occurred in three specimens in the Excalibur group, but none in the manual group. There was no separation of instrument throughout the experiment.
