During root canal treatment, there are two important steps that are crucial for the success of the procedure: access opening and deroofing. These steps are performed to ensure proper cleaning and shaping of the root canal system, as well as effective removal of any infected or inflamed tissue.
Access Opening
Involves creating a small opening in the tooth to gain access to the pulp chamber and root canals. This is typically done using a dental drill and other specialized instruments. The access opening allows the dentist to remove the decayed or damaged tooth structure and provides a pathway to the root canal system.
Deroofing
Refers to the removal of the roof of the pulp chamber, which is the top portion of the chamber that covers the root canals.
This step is important because it allows the dentist to fully visualize and access the root canals, ensuring thorough cleaning and disinfection.
During deroofing, the dentist carefully removes the roof of the pulp chamber using small instruments such as files or ultrasonic tips.
This allows them to see the entire length of the root canals and identify any additional canals or complex anatomy that may need to be addressed during the treatment.
Pulp Extirpation
After creating the access opening, the dentist will use specialized instruments to remove the infected pulp from the pulp chamber and root canals. This process is known as pulp extirpation.
The dentist will carefully navigate through the intricate network of root canals to ensure that all the infected tissue is completely removed. This is crucial for the success of the root canal treatment, as any remaining infected tissue can lead to reinfection and failure of the procedure.
Once the pulp chamber and root canals have been thoroughly cleaned, the dentist will then shape the canals using files of various sizes. This is done to create a smooth and tapered pathway for the filling material that will be placed later.
The shaping of the canals is essential for proper sealing and to prevent any residual bacteria from remaining in the tooth.
After shaping the canals, the dentist will irrigate them with a disinfecting solution to remove any debris or bacteria that may still be present

Overview
Furthermore, access opening and deroofing enable the dentist to accurately assess the anatomy of the root canals. Each tooth can have a complex network of canals, and without proper access and visibility, it can be challenging to identify and treat all the canals.
By creating an access opening and deroofing the pulp chamber, the dentist can ensure that no canals are missed, reducing the risk of leaving infected tissue behind.
Access opening and deroofing are also important for the proper placement of the filling material. When the root canals are properly shaped and cleaned, it allows for a more precise and thorough filling, ensuring that the entire canal space is sealed off from further infection. This is crucial for preventing reinfection and promoting the long-term success of the root canal treatment.
In conclusion, access opening and deroofing are critical steps in root canal treatment. They allow for the effective removal of infected pulp, thorough cleaning and shaping of the root canals, and precise placement of the filling material. By ensuring proper access and visibility, these steps contribute to the success and longevity of the treatment, reducing the risk of reinfection and promoting the healing of the tooth.
