Where does the mandibular nerve pass through in the skull? - ANS Foramen Ovale
What is the maxillary division of the trigeminal nerve? - ANS Sensory
Which nerve is NOT associated with the mandibular nerve branch? - ANS Infraorbital nerve
Which teeth does the PSA injection innervate? - ANS 1st, 2nd, and 3rd maxillary molars
* Does not innervate the mesiobuccal cusp of the maxillary 1st molar
Which injection is needed to anesthetize linguals of maxillary anteriors? - ANS Nasopalatine
Which injections are needed to anesthetize the entire palate on one side? - ANS Greater
Palatine & Nasopalatine
How far do you insert the needle on an IANB? - ANS 20-25 mm or 3/4 the length of the
needle
What happens during depolarization? - ANS - Sodium comes in
- Potassium goes out

,When do you aspirate? - ANS Right before anesthetic is deposited
* This makes sure you do not insert the needle into a blood vessel
Which type of local anesthetic is metabolized by pseudocholinesterase (PABA)? - ANS Esters
What kind of tissue is topical anesthetic least effective on? - ANS Keratinized tissues
What is true about topical anesthetics? - ANS There are no systemic problems with them
Which Ester has the highest occurrence of allergic reactions? - ANS Ester option; Benzocaine
* Only applied topically
What is the significance of giving an amide anesthetic to a patient with Cirrhosis? - ANS The
amide anesthetic is metabolized by the liver
What is the landmark for the IANB injection? - ANS Coronoid notch
Psychogenic pain - ANS No organic base for the pain
What is the maximum epinephrine dose for cardiac & normal patients? - ANS Cardiac- .04mg
Normal- .2mg
What is trismus? - ANS Limited opening of mouth
Management of hematoma - ANS Cold compression & pressure to bleeding site

, Management of trismus - ANS - Heat therapy
- Saline rinses
- Asprin
- Jaw exercises
Hematoma can occur if needle penetrates into the pterygoid plexus of veins during which
injection? - ANS PSA
What needle should be used for infiltration? - ANS 27 short
What is the solution volume of a single cartridge of LA? - ANS 1.7-1.8 ml
Which antioxidant prevents biodegration of LA by stoping oxidation of a vasopressor? -
ANS Sodium bisulfite
What do vasopressors do? - ANS - Increases duration of LA
- Hemostasis (stops blood flow)
- Reduces chance of toxicity
What would cause a dry cornea? - ANS Anesthetizing the facial nerve (VII)
- The facial nerve can be anesthetized if bone is not contacted during an IANB injection and
anesthetic is deposited into the parotid gland causing bell's palsy
- Temporary bell's palsy will not allow the patients eyelid to blink or close, causing a dry cornea
