Maxillary Technique

Question 1

More commonly called local infilatration, is the most frequntly used technique for obtaining pulpal anestesia in maxillary teeth

Answer 1

Supraperisoteal injection

Question 2

Nerves anesthesized of supraperiosteal injection

Answer 2

Large terminal branch of dental plexus

Question 3

Areas anesthesized of supraperiosteal injection

Answer 3

Entire region innervated by the large terminal branch
Pulp and root area of the tooth
Buccal periosteum
Connective tissue
Mucous membane

Question 4

Target area of supraperisoteal injection

Answer 4

Apical region of the tooth to be anesthesized

Question 5

Landmarks of supraperiosteal injection

Answer 5

Mucobuccal fold
Crown of the tooth
Root contour of the tooth

Question 6

Commonly used dental nerve block , however, the mesiobuccal root of the maxillary first molar is not consistently innervated by the nerve lock

Answer 6

Posterior superior alveolar nerve block

Question 7

Nerve anesthesized by PSAN block

Answer 7

Posterior superior alveolar nerve and branches

Question 8

Areas anesthesized by posterior superior alveolar nerve

Answer 8

Pulps of the maxillary third, second, and first molars (72% success rate; mesiobuccal root of the maxillary first molar not anesthesized = 28% of PSA nerve blocks)

Buccal periodontium and bone overlying these teeth

Question 9

Target area of PSAN block

Answer 9

Posterior, superior and medal to the posterior border of the maxilla

Question 10

Landmarks of posterior superior alveolar nerve

Answer 10

Mucobuccal fold
Maxillary tuberosity
Zygomatic process of maxilla

Question 11

This nerve is present in about 28% of the population. When the ASA nerve block fails to provide pulpal anesthesia distal to the maxillary canine, this nerve block is indicated for procedures on premolars and the mesiobuccal root of the maxillary first molar.

Answer 11

Middle superior alveolar nerve `

Question 12

Nerves anesthesized of MSA

Answer 12

MSA nerve and terminal branches

Question 13

Area anesthesized of MSA

Answer 13

Pulps of the maxillary first and second premolars, mesiobuccal root of the maxillary first molar
Buccal periodontal tissues and bone over these same teeth

Question 14

Area of insertion of MSA

Answer 14

Height of the mucobuccal fold above the maxillary second premolar

Question 15

Target area of MSA nerve block

Answer 15

Maxillary bone above the apex of the maxillary second premolar

Question 16

Landmark of middle superior alveolar nerve

Answer 16

Mucobuccal fold above the maxillary second premolar

Question 17

This nerve block provides profound pulpal and buccal soft tissue anesthesia from the maxillary central incisor through the premolars (72% premolars)

Answer 17

Anterior superior alveolar nerve block (infraorbital block)

Question 18

Nerves anesthesized of ASA

Answer 18

Anterior superior alveolar nerve
MSA nerve
Infraorbital nerve
- inferior palpebral
- lateral nasal
- Superior labial

Question 19

Areas anesthesized of anterior superior alveolar nerve

Answer 19

Pulps of the maxillary central incisor through the canine on the injected side
In about 72% of patients, pulps of the maxillary premolars and mesiobuccal root of the first molar
Buccal periodontium and bone of these same teeth
Lower eyelid, lateral aspect of the nose, upper lip

Question 20

Target area of asa

Answer 20

Infraorbital foramen (below the infraorbtal notch)

Question 21

Landmark of ASA

Answer 21

Mucobuccal fold
Infraorbital notch
Intraorbital foramen

Question 22

Nerve block which provides anesthesia in the palatal soft tissues distal to the canine

Answer 22

Greater palatine nerve block or anterior palatine nerve block

Question 23

Nerves anesthesized of GPNB

Answer 23

Greater palatine never

Question 24

Areas anesthesized of GPnerve

Answer 24

Posterior portion of the hard palate and its overlying soft tissues, anteriorly as far as the first premolar and medially to the midline

Question 25

Target area of GP nerve

Answer 25

Greater palatine nerve as it passes anteriorly between soft tissues and bone of the hard palate

Question 26

Landmark of GP nerve

Answer 26

Greater palatine foramen and junction of the maxillary alveolar process and palatine bone

Question 27

An invaluable technique for palatal pain control in that, with administration of a minimum voltage of anesthetic solutin,a wide area of palatal soft tissue anesthesia is achieved, thereby minimizing the need for multiple palatal injection

Answer 27

Nasaopalatine nerve block

Question 28

Nerves anesthesized of nasopalatine

Answer 28

Nasopalatine nerves bilaterally

Question 29

Areas anesthesized of nasopalatine nerve block
