I have not had great success with nickel titanium rotary endo files. I have had problems with files breaking and getting lodged in canals. I also have had a lot of trouble using the right torques settings for the files. These systems are really complex. I would like to use a simple system. Are there any simple nickel titanium rotary systems where you do not have to spend so much time worrying about using the right settings for the torque engine?

Hi. I’ve had good success with the Detsly/ Tulsa GT System. In the 8 years I’ve been using it, I’ve never had 1 rotary file break! I only use the molar files 1x, then toss them. Single canal files I’ll use 2 or 3 times. I think this really helps to control breakage. I have used a J. Morita rotary handpiece in the past, which I was also happy with.
Several factors are involved with successful rotary instrumentation. There are numerous good systems and I currently find good control with Brasseler’s Endosequence files. More importantly, to prevent breakage, you MUST follow these techniques-
-Keep canal lubricated with some type of endo lubricant like Glyde at all times
-DO NOT GET AGRESSIVE with pressure on the files. Use a light touch letting the files progress down the canals. Work a crown-down technique with decreasing file sizes. When file resists, go to next smaller file. The larger filing coronally opens up the canal so there is less chance of binding the instrument and breaking it as you work smaller sizes apically.
-USE MAGNIFICATION and constantly wipe off and inspect the rotary intruments as you go. If you notice any deformity or “unwinding” appearance starting or hear the file starting to make a “clicking” sound, PITCH THE FILE and get a new one. Once you have strained a rotary file enough to see a change, your risk of breakage if continuing with it goes way up!-
-finally, as was stated before, a file set is used in no more than 4 canals before tossing it. If this seems costly to you, think about how you felt the last time a file snapped off deep in a canal and how much you would have been willing to spend at that moment to reverse the situation! I bet it would be a lot more than the cost a file set!
hi i have been using dentsply, protaper system very successfully for 7 years. you MUST keep canal lubricated with glyde, and also use copiously Na HYPOCHLORITE COPIOUSLY. aLWAYS CHECK YOUR FILES FOR EXHAUSTION AND never use pressure. I love doing endo now.
ProFile Vortex from Tulsa Dental is your solution
Please let me be completely open. While I am a practicing endodontist, I also developed the SafeSiders as an answer to the concerns of separated instruments. The substitution of rotary NiTi by 30ยบ reciprocating relieved reamers virtually eliminates separation while shaping even signficantly curved canals rapidly and without distortion. The learning curve is far easier than that of rotary NiTi and the reduced stress from reciprocation allows the reamers to be used several times before disposal dramatically reducing your overhead. It sounds to good to be true, but that is exactly the case.
I use the Endo I T torque control unit from vdw germany. Its easy to use and helps a lot. It has a program for every size and model of rotary file and it also has an auto reverse program, and if the file begins to get stuck it goes on reverse automatically and also makes a warning sound if too much pressure is put on the file.
Recently started using Dentsply protaper system. No hand fatigue, simple system. Don’t reuse files.
