4. NOTE TRANSPORTATION AND LEDGING OF APEX, RESULTING IN AN INADEQUATE SEAL, WHICH WILL MOST LIKELY LEAD TO FAILURE OF THE ENDODNTIC THERAPY

5. Goals of Cleaning and Shaping • Biologic “rid” the root canal system of its pulp, necrotic tissue, bacteria and endotoxins, creating an environment condusive to healing and patient comfort • Mechanical create a continuously tapering preparation that can be obturated in three dimensions
