Question 7

A branch of the anterior division of V3 and consequently is not anesthetized during IANB. Nor anesthesia of the ___ nerve is necessary for most restorative dental procedures

Answer 7

Buccal nerve block

Question 8

Nerve anesthesized of buccal nerve block

Answer 8

Buccal nerve

Question 9

Area anesthetized of buccal nerve

Answer 9

Soft tissues and periosteum buccal to the mandibular molar teeth

Question 10

Target area of buccal nerve block

Answer 10

Buccal nerve as it passes over the anterior border of the ramus

Question 11

Landmarks of buccal never block

Answer 11

Mandibular molars, mucobuccal fold

Question 12

The true mandibular nerve blockbecause it provides sensory anesthesia of virtually the entire distribution of V3

Inferior alveolar, lingual, mylohyoid, mental, incisive, auriculotemporal and buccal nerve are blocked by the technique

Answer 12

Mandibular nerve block: The Gow-Gates technique

Question 13

Nerves anesthesized of the gow gates technique

Answer 13

Inferior alveolar nerve
Mental nerve
Incisive nerve
Lingual nerve
Mylohyoid nerve
Auriculotemporal nerve
Buccal nerve (75% in patients)

Question 14

Areas anesthetized by gow gates injection

Answer 14

Mandibular teeth to the midline
Buccal periosteum and mucous membrane on the side of injection
Anterior 2/3 of the tongue and floor of the oral cavity
Lingual soft tissue and periosteum
Body of the mandibe, inferior portion of the ramus
Skin over the zygoma, posterior portion of the cheek, and temporal regions

Question 15

Target area of gow gates

Answer 15

Lateral side of the condylar neck, just below the insertion of the lateral pterygoid muscle

Question 16

Gow gates landmark

Answer 16

Extraoral
-the intertragic notch (lower border of the tragus). The correct landmark is the center of the external auditory meatus, which is concealed by the tragus

Intraoral
- height of injection established by placement of the needle tip just below the mesiolingual cusp of the maxillary second molar
- penetration of soft tissues just distal to the maxillary second molar at the height established in the preceding step

Question 17

A closed mouth mandibular block technique that can be used in situations where limited mandibular opening precludes the use of other mandibular injections
