Revolutionary Canal Preparation Technology

The Root ZX II Low Speed Handpiece with OTR technology prepares root canals while displaying precise and accurate measurements.

During file rotation, the torque is automatically measured. If the torque is less than the set value, the file rotation continues, but if the torque has reached the set value, the file reverses rotation by 90° and then continues in the cutting direction once again. OTR reduces file fatigue, as well as the possibility of file breakage. 

Lightweight, the handpiece is ergonomically designed to minimize fatigue and fingertip stress and is ideal for endodontic access. It offers 3 speed settings of 100, 300 & 500 rpm and 3 programmable memory modes.



  • Safely & efficiently clean & enlarge canals with OTR technology
  • Reduces the possibility of file breakage
  • Standard Ni-Ti file can be used – no need for special files
  • New contra head has internal file electrode
  • OTR Module can be connected to any Root ZX II


+ Advantages:

OTR Technology  

When the torque setting is reached, the file auto reverses 90° then continues again in the cutting direction. OTR reduces file fatigue, as well as the possibility of file breakage.




Auto Motor Start/Stop 

No foot switch required. Motor starts when file is inserted into the canal and stops when it is withdrawn. 

Auto Torque Reverse

Reduced file breakage. File stops and reverses if the torque goes over the set torque limit. There are 11 torque settings.

Auto Torque Slow Down

Reduced file breakage. File slows down as the torque approaches the set torque limit.

Auto Apical Reverse

File stops and reverses when it reaches the end of the set working length.

Auto Apical Slow Down

File slows down as it approaches the end of the set working length, ensuring safe and accurate preparations.
