The mylohyoid nerve and mandibular anesthesia.

Voluntary dental students received 1 injection of 1,8 ml 3% Prilocain-fenylpressin. The injection was directed beneath the mylohyoid muscle immediately behind the distal root of the first molar in order to achieve anesthesia of the mylohyoid nerve. A partial anesthesia was achieved in 21% of the subjects. In those cases, the mylohyoid nerve is, in addition to its motor innervation, also sensory to first mandibular molar.
