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

Instrumentation can be accomplished by: • Mechanical means -hand instruments such as SS files, broaches, ultrasonics -rotary instruments such as GG, NiTi • Chemical means -irrigants such as NaOCl, EDTA, alcohol, RC Prep, CHX
