It is well known that mandibular second
molar root canal anatomy varies greatly.The present
case report describes the variation in second mandibular
molar .Variation may not always take the shape of
additional canals; it may also take the form of fewer or
smaller canals than what is typical. When the pulpal
floor was examined with an endodontic explorer, a single
round hole was visible in the floor of the pulp chamber.
To confirm the existence of an independent single canal,
many angulated radiographs were taken. Until F5,
ProtaperNiTi instruments (Maillefer, Dentsply) were
used for individual canal preparation. Obturation was
accomplished using the lateral condensation technique
and the sealapex sealer.
A successful root canal procedure depends on
knowing how many root canals are present in the tooth.
Some teeth may have more canals than usual, while
others may have less canals than usual. A solitary canal
in the second tooth on the mandible should be quickly
identified. By removing the necessity to remove
unnecessary tooth material in order to find additional
canals, single canal identification aids in the preservation
of tooth structure.
