Cone beam computed tomography (CBCT) is a popular and often indispensable imaging modality used for the dento-alveolar tissues and immediate surrounding structures. It can be used across several dental disciplines including endodontics, implant planning, oral surgery and orthodontics. Furthermore, it is also commonly used in the medical specialities of oral and maxillofacial surgery (OMFS) and ear, nose and throat (ENT) surgery. In many of the images taken, there will often be findings/presentations that may not be expected, or familiar, to the reporting clinician. CPD/Clinical Relevance: Many incidental findings are innocuous, yet their recognition and documentation are essential because some will warrant medical or surgical intervention.

The Gubernacular Canal is an anatomical structure that can be seen on Cone Beam Computed Tomography, connecting the dental lamina of an unerupted tooth the overlying gingivae at the site of normal eruption. We

Cone beam computed tomography (CBCT) is a popular and often indispensable imaging modality used for the dento-alveolar tissues and immediate surrounding structures. It can be used across several dental disciplines including endodontics, implant planning, oral surgery and orthodontics. Furthermore, it is commonly used in the medical specialties of oral and maxillofacial surgery (OMFS) and ear, nose and throat (ENT) surgery. In part 1 of this series, we described some of the common incidental findings found in the dento-alveolar complex and immediate neighbouring structures. Part 2 looks further afield and depicts some common and important incidental findings and anatomical variants that can be found on larger fields of view. CPD/Clinical Relevance: Many incidental findings are innocuous, yet their recognition and documentation are essential because some will warrant medical or surgical intervention.
