Stop and stare (at your xrays)

As dentists we tend to be problem focused and so have the problem in mind when we analyse a situation. Interpreting xrays is one problem that this attitude can lead us into strife. Since we are teeth focused, we tend to ignore non dental landmarks on a film such as an OPG but forget we are responsible for interpreting everything that is present on any particular radiograph. Similarly, in bitewings and periapical radiographs  we may be giving them a quick scan for obvious pathology and missing subtler aspects such as widening in PDL or bony lesions.

During endodontic treatment we may be so focused on the apex that we fail to notice things such as perforations in the coronal aspect or missed canals. Prior to extractions I would suggest that you have an OPG and zoom into the tooth in question and force yourself to stare at it for a good minute to notice the subtler aspects of the treatment to be performed. Often times what appears as conical roots from a distance may be masking an apical hook or an extra root. Take a more detailed periapical radiograph or CBCT (if required) if in doubt about the procedure plan.
