Rare Root Canal Configuration of Mandibular Second Premolar Using Cone-beam Computed Tomographic Scanning
The aim of this case report was to demonstrate how the use of cone-beam computed tomographic (CBCT) imagery is beneficial when treating a tooth with an unusual anatomic variation. A 43-year-old female patient presented to our private practice after a referral from her general dentist. Endodontic therapy was previously initiated and unable to be completed because of suspicious anatomic anatomy. CBCT imagery confirmed the presence of a C-shaped root configuration and 3 canals within the tooth. Root canal treatment was completed successfully without complications. The use of CBCT imaging was valuable in determining the root morphology and rare canal anatomy to enhance treatment and success.
