[Semeiologic meaning of dilatation of the dental canal]

The authors report two cases of dilatation of the dental canal due to metastases. They review the clinical picture of dilatations of the dental canal which, other than being related to metastases, may be secondary to a haemangioma or a neurofibroma. They express the desire that measurements may be helpful in considering cases at the limit of normal, as for the internal auditory meatus and the optic canals.
