Root canal therapy is a procedure some dental practices offer, and the way in which it is done has advanced significantly over the past two decades. This is partly a result of the changes in methodology, but can also be attributed to the latest technological discoveries. Equipment used in root canal procedures includes the endo handpiece, which allows the dentist to use an automatic motor instead of a manual approach.
The Development of the Endo Handpiece
Endodontic equipment has developed dramatically since nickel-titanium (NiTi) rotary files were introduced in the 1990s. These files enabled better tracking around curved canals and much faster canal preparation, as well as extruding less debris than hand files and leaving a smoother finish. In 1995 endo handpieces ran at 150 rpm maximum, but current handpieces can deliver speeds of up to 900 rpm; which improves the efficiency of dentin removal in a canal.
Using the Endo Handpiece
When using a handpiece for a root canal procedure, the dentist places the NiTi file in the handpiece and uses it to remove gutta percha material previously positioned in the treated tooth. The dentist typically begins with a smaller diameter file, and works up to a larger file until the canal is clear. This is opposite of the old “crown down” technique, in which the use of rotary files progressed from larger to smaller files.
Advancements in NiTi Files
We now have a greater understanding of the effects of torsional stress and cyclic fatigue on rotary file separation, which has enabled file manufacturers to design equipment with different NiTi composition through heat and chemical treatments. Add to this the new changes in file design, and we can understand that the new rotary files are better able to withstand separation and to perform better in a clinical environment.
The Traus Cordless endo handpiece is an engineering masterpiece, which has a simple interface aimed at giving the user easy control during operations. It’s ergonomic and compact, suitable for use with most major brand NiTi files. With five memory functions that enable the user to set the gear ratio, torque, RPM and direction mode, it also automatically runs in reverse rotation once the load is released. Its on-off foot switch and chargeable battery make it versatile and simple to use, and after 4 minutes of no operation it automatically powers itself off.
