Panoramic radiographic risk factors for inferior alveolar nerve injury after third molar extraction

Assessment of the relationship between mandibular molars and inferior alveolar nerve–diagnostic significance and accuracy of panoramic radiography

“…According to Bart F. Blaeser and coworkers, the presence of one or more of radiographic markers represent 40% or higher chance of injury of the inferior alveolar nerve during extraction of impacted molars (13).…”

“…In this case both structures are described as darker and more difficult to define zones ( Figure 2). Third marker represent disturbance in the top and the bottom border of the mandibular canal in the area of intersection with the root canal (11,12,13). …”

No plane is the best one—the volume is!

“…As most authors concur, only "high risk" cases require further imaging. [3][4][5] In fact, this is the reason why only "high risk" cases were evaluated in our study. Others are not of great interest and not available with 3D data.…”

Tooth multi-sectioning with the use of magnification, for extraction of a deeply impacted lower second molar with entrapment of the inferior alveolar nerve: Report of a case

“…Diversion of the inferior alveolar canal, interruption of the mandibular canal and darkening of the root of the impacted molar are the most striking radiological signs associated with possibility of IAN damage 7,8 . In these cases, a further radiological examination with cone beam computed tomography (CBCT) may be recommended to justify the relation of the roots of the impacted tooth to the IAN in 3-dimensional view 9 .…”
