Question 9

BUCCAL INFILTRATION

Answer 9

• Numbs = pulp + buccal soft-t + bone
• Landmark = mucobuccal fold, parallel apex
• Inject = parallel long axis, at/above apex
• Dose = 1/2 cartridge

Question 10

NASOPALATINE BLOCK = max

Answer 10

• Numbs = anterior hard palate (3-3, hard+soft-t)
• Landmark = incisive foramen
• Inject = 1cm palatal to central incisors
• Dose = blanch t

Question 11

GREATER PALATINE BLOCK = max

Answer 11

• Numbs = posterior hard palate (hard+soft-t)
• Landmark = greater palatine foramen
• Inject = U7d
• Dose = 1/2

Question 12

MENTAL BLOCK = mand

Answer 12

• Numbs = 1-4, ≃5 (lower lip + chin)
• Landmark = mental foramen
• Inject = mucobuccal fold anterior to foramen
• Dose = 2/3

Question 13

LONG BUCCAL BLOCK = mand

Answer 13

• Numbs = soft-t + periosteum buccal to molars
