A plastic tube technique for direct vision of endodontic procedures

A technique for the direct visualization of endodontic procedures utilizing clear plastic tubes machined to simulate root canals is described. The visualization of endodontic procedures allows for their evaluation by the clinician as well as their use as an adjunct to didactic courses in endodontics. During mechanical instrumentation it is evident that a concerted effort must be made to debride all of the walls of a canal. Hydraulic forces are seen to play a major role in irrigation and in applying root canal cement. The technique also reveals voids in the completed root canal filling when verticle condensation is used to obturate the canals.
