[Odontologic and other etiologic factors in trigeminal neuralgia].

Trigeminal neuralgia may be due to many causes, being in this respect secondary. To a certain degree trigeminal neuralgia may be facilitated by an individual increase of reactivity in the trigeminal system to noxious factors. For this reason, in treating trigeminal neuralgia, it is necessary first of all to take into consideration the possible etiological factors including different diseases of the teeth, in the innervation of which an important role is played by the fibers of the trigeminal nerve.
