Numb Chin Sign and the Role of Radiology.

The numb chin sign is an important clinical sign that compels dentists to consider a serious disease that could be both local or distant. In addition to the clinical examination and history taking, appropriate radiology is required. Although today cone-beam computed tomography (CBCT), due to its widespread availability, as a valuable modality in dental practice, it still rests on appropriate lower-radiation-dose conventional radiography. The choice of the appropriate reconstruction of the CBCT dataset enhances the quality of the interpretation without adding further to the radiation dose, as illustrated in this rare case report.
