A sonic vibratory device with the shape, size and weight of a dental handpiece has been developed for the instrumentation of root canals. Specially designed K‐type files are used with the handpiece, which is air‐driven and may be attached to the high‐speed air line of a dental unit. A clinical study was performed using conventional hand instruments and the sonic system in the instrumentation of root canals. Also studied was the use of continuous irrigation of the root canal with EDTA and filtered tap water with the sonic device. Instrumentation time, procedural and clinical complications, as well as overall suitability of the new device were evaluated. The results indicated that the sonic vibratory system was well‐suited for root canal instrumentation. The vibratory files appeared safe and complications were well within acceptable limits. Irrigation with a continuous flow of EDTA was not acceptable, mainly because of crystallization and clogging of tubes and handpieces. Filtered tap water was well‐tolerated and its cleaning effect was good. The sonic device could be used with ease and resulted in decreased operator fatigue when compared with hand instrumentation.
