DARK ROOT APEX
This marker is similar to notching. A dark root apex may indicate intimate nerve contact for older patients. The dark apex may also indicate an open apex for young patients whose third molar roots are still developing. It is seen on a radiograph as a radiolucent third molar apex and loss of the top white line as the canal passes over the root. This radiographic marker increases the possibility of IAN paresthesia.
