p3 anesthesiology intraoral inejctions (max & mand)

true

true or false: Injections should not be performed in areas of infection or inflammation

mandible

this is the strognest and largest facial bone

1. lingual plate

2. buccal plate

in the mandible, it is composed of two pieces of thick coritcal bone, name two

horseshoe-shaped body

in the mandible, the teeth are contained in what shaped body?

coronoid notch

in the mandible, this is the concavity on the anterior portion of the ramus used to estimate the height of the mandibular foramen, which also is located at the height of the occlusal plane

1. buccal nerve

2. inferior alveolar nerve

3. lingual nerve

bil

what are the three associated nerves of the mandible?

inferior alveolar nerve

in the mandible, which nerve enters the mandible at the mandibular foramen

lingual nerve

in the mandible, which nerve enters the oral cavity passing against the lingual tuberosity

buccal nerve

in the mandible, which nerve lies on the buccal shelf

thickness of the cortical bone

in the inferior alveolar nerve block overview, Clinically acceptable mandibular anesthesia is more difficult to achieve than maxillary anesthesia because of the

1. ingerior alveolar nerve

2. lingual nerve

inferior alveolar nerve block anesthetizes two nerves

pterogomandibualr space

in the ian block, Requires anesthetic deposition in the __________________ at the region of the mandibular foramen lateral to the sphenomandibular ligament

1. all mandibular teeth (inferior alveolar nerve)

2. Epithelium of the anterior 2/3rds of the tongue (lingual nerve)

3. All lingual gingiva and lingual mucosa (lingual nerve)

4. All buccal gingiva and mucosa from the premolars to the midline (mental nerve)

5. Skin of the lower lip (mental nerve)

in ian nverve block, lsit the 5 areas to be anesthesized

children

in ian considerations, the mandibular foramen is located closer to the posterior border of the mandible until

more bone is added with age, this is in?

edentulous patients

in ian consideration the alveolar bone is lost; thus, the deepest part of the coronoid notch is

lower than normal, which could lead the clinician to aim the needle too low, this is in?

class ii malocclusion

in ian consideration, when the mandible is hypoplastic, the mandibular foramen is typically

located more inferior than the clinician may think, this is in?

​

class iii malocclusion

in ian consideration, when the mandible is hyperplastic, the mandibular foramen is typically

located more superior than the clinician may think, this is in?

​

Bell's Palsy

this condition happens if the needle is placed too far posteriorly in the

parotid bed and anesthetic is introduced close to the facial nerve

long buccal nerve block

this nerve block is:

-A branch of the mandibular division of the trigeminal nerve, the long buccal nerve is not

anesthetized in an inferior alveolar injection

- This block anesthetizes all buccal gingiva opposite the mandibular molars, including the retromolar

trigone

​

hemotoma

this condition is rare wti this block but it must be considered in the long buccal nerve block

2mm

in the long buccal nerve block, how much mm should the needle be inserted into the mucosa posterior to the last molar in the mandibular arch on buccal side

mental nerve block

this nerve block is:

-A Branch of the inferior alveolar nerve within the mandibular canal

areas anesthesized:

● All buccal gingiva and mucosa from the premolars to the midline (mental nerve)

● Skin of the lower lip (mental nerve)

​

1. long buccal nerve block

2. mental nerve block

two mandibular injections that are seldom to fail

GOW - GATES BLOCK

this mandibualr injection is a variation of the inferior alveolar nerve block, it anesthetizes the following nerves:

● Inferior alveolar nerve (and its branches, the mental and incisive nerves)

● Mylohyoid nerve

● Lingual nerve

● Long buccal nerve (often)

● Auriculotemporal nerve (often)

intertragic notch

in gow-gates block, what part of the mandible is used extraoral landmark to help reach the neck of the

mandibular condyle

akinosi block

this nerve block A closed-mouth approach for the mandibular nerve block, it anesthetizes the following nerves:

● Inferior alveolar nerve (and its branches, the mental and incisive nerves)

● Mylohyoid nerve

● Lingual nerve

akinosi block

this mandibular nerve block is Useful when mandibular depression (opening) is limited, such as with trismus

akinosi nerve block

what mandibular nerve block is considered a "blind" injection

akinosi nerve block

this mandibular injection is:

-Often used in patients with a limited ability to open the mouth and when intraoral landmarks for

a standard inferior alveolar nerve block are difficult to view

- Good for patients with a strong gag reflex or macroglossia

maxilla

this bone is:

-One of the largest facial bones

-Porous bone, which aids in achieving anesthesia of the maxillary teeth

1. anterior alveolar nerve

2. middle alveolar nerve

3. posterior alveolar nerve

in the maxilla, the maxillary teeth are supplied by 3 types of alveolar nerve

1. palatal process of the maxilla

2. horizontal plate of the palatine

in the maxilla, the hard palate is composed of two parts, name the two parts

1. nasopalatine nerve

2. greater palatine nerve

in the maxilla, the hard palate is supplied by two nerves

POSTERIOR SUPERIOR ALVEOLAR NERVE BLOCK

this is frequently used nerve block in the maxillary injections

ifnratemporal fossa

in the posterior superiro laveolar nerve block, the injection is in which fossa?

posterior superior alveolar nerve block

this maxillary injection:

-Areas anesthetized:

• All maxillary molars, with the possible exception of the mesiobuccal root of the 1st maxillary

molar

• Buccal gingiva opposite the teeth

short needles

in posterior superior alveolar nerve block, what type of needles are preferred, to reduce the risk to hematoma

nasopalatine nerve block

this maxillary injection is Considered the most painful of dental injections ( due to sensitivity of the area)

nasopalatine nerve block

this maxillary injection areas anesthesized:

-The area's palatal gingiva and mucosa from the maxillary canine on the right to the maxillary

canine on the left side of the maxilla

• Both the right and left nasopalatine nerves, because they exit onto the hard palate in close

proximity Oral mucosa in this region is tightly adhered to the hard palate; thus deposition of anesthetic

in the area has less space to diffuse

pressure anesthesia

in nasopalatine nerve block, what is beneficial to help lessen the pain

true

true or false: in nasopalatine nerveblock, Because the tissue is so dense and is attached to the bone, this block requires a slow injection

greater palatine nerve block

this maxillary injection is Another commonly used block to anesthetize areas of the hard palate Not as traumatic for the

patient as the nasopalatine nerve block

​

true

true or false: middle superior alveolar nerve is reported to be present in about 30% of all people

local infiltration

in the consideration of the middle superior alveolar nerve, what is a common substitute for this block?

infraorbital/ anterior superiro alveolar nerve block

this maxillary injection is Less frequently used because of the risk of the clinician injuring the patient's eye

INFRAORBITAL/ ANTERIOR SUPERIOR ALVEOLAR NERVE BLOCK

This block anesthetizes the following nerves:

• Anterior superior alveolar nerve

• Middle superior alveolar nerve

• Infraorbital nerve

Areas anesthetized:

• All maxillary teeth from the central incisor to the premolars, with the possible inclusion of

the mesiobuccal root of the 1st maxillary molar

• Buccal gingiva opposite these teeth

• Lateral aspect of nose, lower eyelid, and upper lip

MAXILLARY DIVISION BLOCK

this maxillary injection is:

-An excellent technique to achieve hemimaxillary anesthesia

-Anesthetizes all of the branches of the maxillary division of the trigeminal nerve Useful in extensive

quadrant procedures and surgery

MAXILLARY DIVISION BLOCK

the following nerves are anesthetized:

• Posterior superior alveolar nerve

• Middle superior alveolar nerve

• Anterior superior alveolar nerve

• Nasopalatine nerve

• Greater palatine nerve

• Infraorbital nerve

Areas anesthetized:

• All maxillary teeth

• All buccal gingiva

• All palatal gingiva and mucosa

• Lateral aspect of nose, lower eyelid, and upper lip
