Efficiency of a Guiding Device for Inferior Alveolar Nerve Block, EZ-Block®, Compared to a Conventional Freehand Administration.

"Once the anesthesia is performed by the Anesthesia practitioner either with the EZ-Block® device or by the conventional freehand technique, the surgical procedure will be performed in the same way in both arms, and for each tooth, by the Surgery practitioner:~* The Surgery practitioner takes charge of the patient after a post-anesthesia time of 10 minutes and performs a new antisepsis then completes the anesthesia by anesthetizing the buccal and lingual nerve with a carpule of 1.8ml of articaine + adrenaline at 1/200000.~* The Surgery practitioner starts the surgical procedure.~* In the absence of pain, the practitioner Surgery carries out the surgical act in its totality (situation of success for the principal criterion of the study) then records the EVA at the end of the intervention."
