Endodontic Files and Reamers
Endodontic files and reamers (pronunciation: en-doh-DON-tik files and REE-mers) are dental instruments used in endodontics, the branch of dentistry that deals with diseases of the tooth root, dental pulp, and surrounding tissue.
Etymology
The term "endodontic" is derived from the Greek words "endo" meaning inside and "odont" meaning tooth. "File" and "reamer" are English words, with "file" originally referring to a tool for shaping or smoothing rough surfaces and "reamer" referring to a tool for enlarging or finishing a hole.
Description
Endodontic files and reamers are used to clean and shape the root canal during a root canal treatment. They are typically made of stainless steel or nickel-titanium and come in various sizes and tapers to accommodate different root canal shapes and sizes.
Endodontic files are used to enlarge the canal and remove debris and bacteria. They have a twisted design which allows for aggressive cutting of the dentin.
Endodontic reamers, on the other hand, have fewer twists in their design, making them more flexible and less aggressive. They are used for initial exploration of the canal and for removing loose debris.
