Refining the Access
Ultrasonics makes access faster and less invasive.
The access is the first phase of endodontic treatment. It permits entry to the pulp chamber through the removal of its roof as well as dentin, facilitating the access to the canal orifices. A well designed and well executed access is paramount to achieving proper cleaning, shaping, and obturation of the root canal system.
1st Law of canal location
The root canal access is always located in the wall-floor junction.
2nd law of canal location
The root canal access is always located in a vertex.
Step-by-Step Access Refining
1 – Choose a round shaped ultrasonic insert (E3D, E6D or E7D)
2 – Place the insert inside the pulp chamber. Do not turn on the vibration (footswitch) until the ultrasonic tip is touching the dentin.
3 – Wear out any interferences and materials that may be blocking the access to the root canals.
1. Access with pulp chamber roof remaining.
2. Place insert inside the pulp chamber, contact the dentin, and then activate ultrasonic action.
3. Remove all interferences obstructing access to canals.
