Which term refers to the material used to seal the cleaned root canal?

The term that refers to the material used to seal the cleaned root canal is the root canal sealer. This material is essential in the endodontic procedure as it fills any voids within the canal and helps to create a hermetic seal, preventing bacteria from re-entering the canal system after treatment. The root canal sealer works in conjunction with a core filling material, such as gutta percha, which fills the main portion of the canal.

While gutta percha is a common and effective material for the obturation of the root canal space, it is often used together with a root canal sealer to ensure complete sealing and enhance the effectiveness of the treatment. Other options like the endo measuring device are tools used during the procedure, and cavit is a temporary restorative material, but they do not serve the purpose of sealing the cleaned root canal. Therefore, the correct terminology for the sealing material is root canal sealer, as it directly addresses the need for sealing and protecting the cleansed canal space.
