GROOVING
The inferior alveolar canal develops before third molar roots. Grooving of the third molar root is caused by a third molar root developing in close proximity to the IAN. Thinning of the developing root is caused by contact with the inferior alveolar canal. This condition, known as grooving, is indicated on radiographs by a radiolucent band where the canal crosses over the third molar root. The canal’s radiographic white lines are not visible on the radiograph. Grooving increases the possibility of IAN paresthesia.
