Endodontic Instrumentation of the Maxillary Fourth Premolar in Dogs and Our Clinical Perspective on a Micro-CT Study

This lecture will review the findings of a micro-CT study1 of the pulp cavity anatomy of Maxillary fourth premolar teeth in dogs. Some of the relevant observation for root canal treatment were the variations in the number and shape of pulp horns, the variations in the localization of root canal orifices, and the 150° curve in the palatal canal under the protocone. With regards to those findings, tricks, opinions or further questions will be discussed and will cover coronal access localization and angulation, instrumentation of the pulp chamber and of the pulp canals.
