What is an Endodontic Reamer and How Does it Work?

Endodontic reamers are precision instruments used in dentistry to create smooth surfaces in root canals and facilitate channel negotiation. They are made of quality stainless steel and superior manufacturing methods, and have fewer coils than K files, generally a triangular cross section, and are used in rotation. These factors make the reamers a flexible and efficient rotating cutting instrument. Manual files are still essential for endodontic practice, and offer design and application options such as files with a variable or accented cone, a nickel-titanium construction, and tips with secure tips. The choice between the two types of instruments depends largely on the doctor's preference. Endodontic reamers are used to prepare the root canal for filling.

The reaming movement is associated with less transport through the channel than a clockwise movement used by K files. This helps to ensure that the root canal is properly shaped for filling. The reamer is inserted into the root canal and rotated in a clockwise direction. As it rotates, it cuts away at the walls of the root canal, creating a smooth surface that is ready for filling. The reamer should be removed from the root canal after each rotation to prevent over-reaming. Endodontic reamers are an important tool in endodontic practice, as they help to ensure that the root canal is properly prepared for filling.

They are also an efficient way to achieve channel negotiation and create gliding routes.
