Abstract
Aims: This clinical case shows the importance of computed tomography as a complementary exam for the surgical planning and treatment of impacted third molar extraction surgery when it is in close contact with the inferior alveolar nerve.
Presentation of the Case: This study reports a clinical case where an impacted lower third molar indicated for extraction had its roots in intimate contact with the inferior alveolar nerve, requiring a cone beam computed tomography for the planning and execution of the surgery.
Discussion: Although the CBCT scan subjects the patient to a higher dose of radiation compared to panoramic radiography, it offers a 3D view of the local anatomy, preventing possible accidents and complications related to the surgical procedure.
Conclusion: Computed tomography showed to be of great importance when the panoramic radiography does not allow a correct visualization of the relation of the inferior alveolar nerve with the tooth to be extracted.
Keywords: Third lower impacted molar, inferior alveolar nerve, cone beam computed tomography
