In this video an actual endodontic access procedure is shown as seen through the microscope:

1. Initial penetration of the crown lingual to the MB cusp tip 2. The first bur extension from the initial penetration point toward the palatal 3. The second bur extension sweeping toward the distobuccal 4. Removal of the pulp chamber ceiling 5. Identification of orifices and grooves 6. Strategic Extension (characteristic of the "SEE" access) 7. Orifice widening
