the needle. This should anesthetize the lingual nerve.
- Finish anesthesia of the area with a long buccal injection (see Figure 5-6). Insert the needle
in the mucobuccal fold at a point just anterior to the first molar. Gently pass the needle, held parallel
to the body of the mandible, with the bevel down, to a point as far back as the third molar, depositing
the solution slowly while advancing the needle through the tissue.
- After a 5-minute interval, evaluate the results of the injections by checking the following symptoms:
(a) Inferior alveolar nerve (supplies lower teeth, alveolar bone up to the midline).
(1) Swelling and numbness extending to the midline of the lower lip on the injected side
(2) Numbness of the facial gingival tissue extending to the midline on the injected side.
(b) Lingual nerve.
(1) Swelling and numbness extending to midline of the tongue.
(2) Numbness of the lingual gingival tissue extending to the midline.
(c) DO NOT ATTEMPT EXTRACTION UNTIL FINDINGTHE SIGNS DESCRIBED ABOVE.
