Abstract
A mandibular first molar with more than four canals is an interesting example of anatomic
variations, especially when four of these canals are located in distal roots. This
report describes a case of a mandibular first molar with six canals (two mesial and
four distal canals in two distal roots). The canals were equipped with a K-file and
irrigated with NaOCl (5.25%) and normal saline as the final irrigant. The canals were
filled laterally with gutta percha and AH26 sealer (De Trey, Dentsply, Switzerland).
This case shows a rare anatomic configuration and points out the importance of looking
for additional canals.
