What is the main purpose of barbed broaches?
To engage and remove soft tissue from the canal
Which group of instruments primarily uses reciprocating motion?
Group V: Engine-driven reciprocating instruments
What is the primary function of a Hedström file in endodontic treatment?
To remove dentin and debris with its cutting action
What is the distinguishing feature of a K-type file compared to a Hedström file?
It adapts three-dimensionally to the shape of the root canal
What is the role of a Uni-file in endodontic treatment?
To efficiently remove dentin and debris with its rhomboidal cross-section

To reach areas that are not possible with rigid instruments
How does a Nickel Titanium (NiTi) file differ from a Hedström file?
It uses a reciprocating motion for cleaning and shaping the canal
Study Notes
Endodontic Instruments
- Gates-Glidden (GG) burs and Peeso reamers are types of endodontic instruments.
Adaptability in Root Canals
- Instruments that can safely operate in and adapt to curved root canals are engine-driven instruments.
Three-Dimensional Adaptation
- Instruments that adapt themselves three-dimensionally to the shape of the root canal are NiTi files.
Barbed Broaches
- The main purpose of barbed broaches is to remove pulp tissue and remaining debris from the root canal.
Reciprocating Motion
- Reciprocating motion is primarily used by hand files and reamers.
Hedström File Function
- The primary function of a Hedström file in endodontic treatment is to shape and clean the root canal.
K-Type File vs. Hedström File
- The distinguishing feature of a K-type file compared to a Hedström file is its triangular cross-section.
Uni-File Role
- The role of a Uni-file in endodontic treatment is to shape and clean the root canal in a single file system.
Importance of Flexibility
- Flexibility is important in endodontic instruments because it enables them to navigate curved canals without breakage.
NiTi File vs. Hedström File
- A Nickel Titanium (NiTi) file differs from a Hedström file in its superelastic properties, allowing it to be more flexible and resistant to breakage.
Test your knowledge of intracanal instruments by identifying and categorizing them into six groups based on their operational methods and specific instrument types.
