D uring Dr Sonntag’s re- cent presentation in March at the University of Warwick, he began by describ- ing the Mtwo endodontic file manufactured by VDW in Ger- many. The file is NiTi in nature and is supplied in sizes: 10/04, 15/05, 20/06, 25/06, 30/05, 35/04, 40/04, 25/07. The file is manufactured from an “S”-shaped blank and has therefore two cutting edges al- lowing it to be very flexible. It is intended for use at 280rpm. The first file and each subsequent file are intended to go to full length. If greater coronal taper is need- ed, then the 25/07 is the file to achieve the greater taper. The 10/04 and 15/05 are very useful in shaping the api- cal third. The files can have a “working part” of either 16mm or 21mm. The latter can be use- ful in the “long canal” scenario – working on canines. The files can be supplied in 25mm and 31mm lengths. Perfecting techniques Dr Sonntag described the tech- niques he has perfected in us- ing these files and the results were impressive. He demon- strated the re-treating of an up- per right first molar which had a discharging extra-oral sinus, prominently situated in the right cheek. The VDW torque control drive system was used to pre- pare the canal with the appro- priate torque setting and speed control. The VDW ultrasonic was also available for trough- ing the pulpal floor, especially for the isthmus between MB1 and MB2. The afternoon was spent discussing the obturation of the canals that had been prepared by the students. The VDW “Bee Fill” gutta percha extruder was demonstrated, which is on par with the other gutta percha ex- trusion systems on the market at present. To summarise, this was a very refreshing course on the VDW endodontic spectrum of root canal armamentaria. A word of thanks Praise goes to Dr David Sonntag for the tuition; QED for supply- ing the full range of VDW in- struments and files; DP Medical for supplying the Global micro- scopes and to Dr Liviu Steier as course co-ordinator.
