Abstract:
Background
Mandibular premolars generally have single root
and single root canal. The frequency of mandibular
premolars with two roots and three canals is extremely
rare.
Objective
To present the management of a mandibular second
premolar with two roots and three canals which was
identified by cone-beam computed tomography
(CBCT)
Case Description
13 years old male patient having pain in the right
mandibular second premolar was referred for the
endodontic treatment. The preoperative periapical
radiograph showed the presence of two roots. After
identification of three canals by CBCT two in the
distal root and one in the mesial root, the endodontic
treatment was performed. Radiographic follow-up of
the case revealed no signs of periapical inflamation
after one year.
Conclusion
Dental anatomical variations are important and must
be identified preoperatively for a successful treatment
outcome in endodontics. CBCT can be used for the
preoperative diagnosis of complex root canal anatomy
