Abstract

The major causes for persistent intracanal infection are unfilled canals and incomplete obturation resulting in endodontic failure. A thorough knowledge of the root canal anatomy and accurate interpretation of preoperative radiographs are essential aspects of endodontic therapy. Quite often the third root or canal is missed as it is not visible under normal vision. Three rooted maxillary premolars have similar root canal morphology as that of maxillary molars and are described as ‘Radiculous’. According to Vertucci, the incidence of three canals in maxillary second premolar is 0.3 to 2%. This case report describes the clinical diagnosis and endodontic retreatment of radiculous maxillary second premolar, drawing particular attention to access refinements aided by ultrasonics and dental operating microscope.
