Question

Which of the following is used to enlarge canal opening?

• A. K-file
• B. Reamer
• C. Gates Glidden drill
• D. Path finder

Hint:

The Gates Glidden drill is essential for enlarging the canal orifice, making it easier to access and clean the root canal.

Answer 1

The Correct Option is C

The Gates Glidden drill is a rotary cutting instrument that is commonly used in endodontics to enlarge the access cavity and shape the coronal portion of the root canal. It is specifically designed to enlarge the orifice (opening) of the canal in order to provide better access to the canal for cleaning and shaping. 
The Gates Glidden drill is a cylindrical bur that is available in various sizes and lengths, and it is designed to fit into a slow-speed handpiece. The drill is used to remove the roof of the pulp chamber and to smooth and shape the walls of the access cavity. It is often used in conjunction with hand files and reamers to prepare the root canal for filling. 
K-files and reamers are manual endodontic instruments that are used to clean and shape the root canal. K-files are flexible, tapered instruments that are used to remove debris and shape the canal, while reamers are rigid, tapered instruments that are used to remove dentin and debris from the canal walls. 
These instruments are used after the canal has been accessed and the Gates Glidden drill has been used to enlarge the orifice. A pathfinder is a type of endodontic instrument that is used to locate the root canal orifices. It is a thin, flexible wire that is inserted into the canal to help guide the placement of other instruments.
