Classification of Intracanal Instruments

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.
