Anatomical variations should be kept in mind in clinical and carefully looked for in radiographic evaluation during endodontic treatment of maxillary premolars. These teeth have highly variable root canal morphology. Although three separate roots in the maxillary first premolars have been reported, it is a rarity to find both the first and second premolars possessing three separate roots. This case report describes the diagnosis and endodontic management of maxillary first and second premolars with three canals and three separate roots...

The practice of endodontics, while not as common as today, was performed during the WWII era. Some of the materials used to fill canals during this time period include gutta-percha, calcium hydroxide, gold foil, and silver points. In this case study, fissures and fractures were present on the exposed root surfaces of the dental remains. Radiographs of the dental remains revealed canal systems similar to those obturated with a paste or semi-solid material. The root surface defects appear to be the access point for the radiopaque material...

The success of endodontic therapy is based on having sufficient endodontic access, correct cleaning and shaping, and adequate root canal obturation. However, endodontic treatment is also dependent on having a sound knowledge of the internal anatomy of human teeth, especially when anatomic variations are present. Reporting these alterations is important for improving the understanding and expertise of endodontists. The aim of this case report is to describe a unique case of maxillary first molar with 2 palatal canals within a single root, as confirmed by cone-beam computed tomography (CBCT) scans...
