Unusual maxillary second premolar morphology: a case report.
This case report presents the relatively uncommon occurrence of a maxillary second premolar with 3 root canals. The possibility of additional root canals should be considered even in teeth with a low frequency of abnormal root canal anatomy. Sound knowledge of root canal anatomy, critical interpretation of radiographs, and high-magnification examination are essential elements of success in complicated root canal therapy.
