HOSA Dental Terminology Practice

Which of the following describes the function of reamers?

1. To fill amalgam

2. To shape and clean canals

3. To measure root length

4. To seal dentin

The correct answer is: To shape and clean canals

Reamers are specifically designed instruments used primarily in endodontics, the branch of dentistry that deals with the treatment of dental pulp and root canal procedures. Their main function is to shape and clean the canals within the tooth during root canal treatment. The unique design of reamers, which typically features twisted or helical grooves, allows them to remove debris and dentin efficiently while also enlarging and tapering the canal to prepare it for filling materials. This distinction in function is crucial, as it directly relates to the success of root canal therapy. Proper shaping and cleaning of the canal help to eliminate infected tissue and prepare it for sealing, significantly reducing the risk of reinfection. The other options, while relevant to dental procedures, do not accurately describe the specific role of reamers in the context of endodontic treatment. Hence, the choice that states reamers are used to shape and clean canals is indeed the correct answer.
