RESUMO
Correct diagnosis of root canal anatomy is very important to ensure successful root canal treatment. Mandibular first premolars with three separate root canals are very rare. Consequently, they often require specific shaping and obturating techniques. This report describes the diagnosis and non-surgical treatment(s) of bilateral mandibular first premolars with three separate root canals.
RESUMO
Variations in the number of roots and canals have been extensively reported in endodontic literature. One rare variation is presence of two separate root canals in maxillary lateral incisors. This study reports a maxillary lateral incisor with two canals. Although rare, knowledge about this anatomical variation can help in successful endodontic treatment of such teeth.
