Where is the bevel of the needle always pointed?
-Always toward the bone
When you insert a short needle how much of the needle still needs to be visible?
-4 mm
How far do you insert a large needle?
1/2 its length
What nerve blocks do you find in the maxilla?
- PSA
- MSA
- ASA
- Greater palatine block
- Infraorbital block
- Nasopalatine
What nerve blocks do you find in the mandible?
- IA
- Buccal
- Mental
- Incisive
- Gow-Gates mandibular nerve block
If you are using multiple drugs what should they never exceed?
-The maximum of the lower total amount
If you have to inject into an abscess what type of anesthetic would you use?
-Carbicaine because of the acidic pH of the infection
T/F You should change needles if you have injected into an infection
True
What are category B drugs?
- Lidocaine
- Prilocaine
- Etidocaine
What is pulpal (supraperiosteal) anesthesia?
-Through anesthesia of each nerve’s dental branches as they extend into the pulp tissue
What block is recommended for maxillary molar teeth and associated buccal tissues in one quadrant?
-PSA
What block is recommended for maxillary premolars and associated buccal tissues?
-MSA block
What block is recommended for maxillary canine and the incisors in one quadrant?
-ASA
What block is recommended for palatal tissues distal to the maxillary canine in one quadrant?
-Greater palatine block (V2)
What block is recommended for palatal tissues between the right and left maxillary canines?
-Nasopalatine block
What block is used for the soft and hard tissues of the palatal periodontium (gingiva, PDL, alveolar bone)?
-Palatal blocks
What does a PSA nerve block?
-Pulpal maxillary 3rd, 2nd and 1st molars
What occurs if you go to deep with a PSA injection?
-Blanching of the cheek (damage of the pterygoid plexus and maxillary artery)
Where do you aim for on a PSA nerve block?
-Apex of the 2nd maxillary molar
When is an MSA block indicated?
-Maxillary pre-molars and mesiobuccal root of 1st molar
What is the target area of the MSA?
-Apex of 2nd premolar
T/F An ASA block can cross the midline to the opposite side?
-True
When doing an ASA block what is your target?
-Apex of the maxillary canine
