Endodontic Access: Proper Access for Maxillary Molars
THE NEXT DDS
Learning Objectives:
After watching this video, the viewer should:
- Understand
how to properly access the mandibular molars in endodontic procedures
- Know
the sequence of instrumentation and steps associated with mandibular molar
access
When initiating access on a maxillary molar it is essential
to have proper straight-line access in order to ensure successful endodontic
treatment. Using a high speed rotary instrument, remove the roof of the
chamber. When the roof of the chamber is removed, change to a slow speed rotary
instrument, preferably #6 or a #8 round bur, in order to remove tissue and
debris from the chamber. A diamond bur can also be used at this stage to remove
overhangs and refine straight line access.
