Root canals and apical foramina of the buccal root of maxillary first premolars with longitudinal sulcus

Better prognoses in endodontic treatment can only be achieved if dentists have thorough knowledge of the internal anatomic configuration of teeth. Lack of knowledge of internal dental anatomy and anatomic variations may lead to errors in identification, instrumentation and obturation of root canals. Some classic studies on internal dental anatomy have provided important data for better understanding of Endodontics, thus contributing to the success of root canal therapy.




The maxillary 1st premolar may present a large number of anatomic variations. Root canal treatment of this tooth is difficult because of the direction and longitudinal depression of its roots, the different con figurations of the pulp chamber and the difficulty in visualizing the apex on radiographs.
