What are Rotary Files

Endodontic procedure rotary files have only come into existence only a decade and half ago. The introduction of the rotary files is regarded in the dentistry circle has a grand rip towards an advanced technological advancement dentistry. This is however the imminent minimization of a rotary file. A definition of a rotary file should be given to answer the question; what are rotary files. Rotary files are tools or better yet instruments that are used by doctors to perform root canal treatment. The instruments are particularly used to clean as well as shape the root canal.

The files are primarily made from metal; in particular steel or an alloy of nickel plus titanium. A proper endodontic file enables the endodontic treatment to be a success. Click the link to know what are protaper files and how can they be used.



Clinically endodontic usually fracture and as a result jeopardizing the results of the endodontic procedure being carried out. For professional handling of the rotary, a dentist needs to be specially trained. In addition there is a user manual that any dentist can go through with ease to grasp the needed tips on how to handle the file.
Below are tips on how to minimize the separation of rotary files.


• Comprehending the torque and cyclic fatigue
The main widespread aspects that result in file separation may perhaps include: extreme force, also known as torque, and the accumulation of cyclic weariness; also commonly referred to as metal fatigue. A Torque comes up as a result of the twisting motion akin to slanting a pencil in reverse directions. If this occurs the instrument should be discarded.

On the other hand, a cyclic fatigue is not easily noticed. Cyclic fatigue gathers to the extent of separating the instrument altogether. To prevent a cyclic fatigue, the instrument should be discarded immediately after the procedure is done.

Conventionally rotary files that separate in 1 to 3 mm are more often than not as a result of excessive torque. Files that separate in a higher level for instance 5 to 6 mm are characteristically as a result of cyclic fatigue.

• Landed and non-landed rotary files
By design rotary files are either landed or non-landed instruments. However, each comprises its own benefits as well as limitations in regards to separation.

By definition, Landed rotary files chafe alongside the inner canal wall to increase lateral resistance. As a result a noteworthy boost to the amount of torque is realized. On the other hand, non-landed rotary files comprise of less torque requirements in comparison to landed files. Non-landed rotary files are capable in cutting and shaping groundwork.

Each and every dentist must exercise due diligence to get acquitted to both the probable risks as well as the benefits of the rotary file system that they use.

• keep a file moving at all times
Upon presentation of a rotary file a dentist should test how it can be broken. Rotary files that are used improperly are susceptible to being separated.

Further inquest of understanding what a rotary file, a user should understand the various aspects of the file. This will make easy the use, maintenance as well as the independent decision to repair or discard the file when it is regarded out of order.
