1. Anesthesia of mandibular teeth in adults by the infiltration
method would be achieved best by the use of:
A. 1.8 mL of Prilocaine 4% + epinephrine 1:100,000.
B. 1.8 mL of Bupivacaine 0.5% + epinephrine 1:200,000.
C. 1.8 mL of Mepivacaine 2% + levonordefrin 1:20,000.
D. 1.8 mL of Articaine 4% + epinephrine 1:100,000.
correct answer : (D) 1.8 mL of Articaine 4% + epinephrine
1:100,000.
Articaine 4% with 1:100,000 epi was introduced in June 2000. Four
well designed studies showed articaine to be more successful in
achieving adequate anesthesia than lidocaine in mandibular teeth.
One theory is that articaine is more effective due to it's higher
concentration. The second theory is that articaine has a thiophene
ring that enables it to diffuse more effectively than the other local
anesthetics that have a benzene ring.

mepivicaine, and bupivicaine in pregnancy riskcategory of _______.

The US Food & DrugAdministration has classified lidocaine &
prilocaine in pregnancy risk category B
and articaine, mepivicaine &bupivicaine in category C
C. Category A: adequate & well-controlled studies have failed to
show a risk to the fetus inthe first trimester of pregnancy (and
there is no evidence of risk in later trimesters).
Category B: Either (1)adequate & well-controlled studies have failed
to show a risk to fetus in the first trimester of pregnancy, and
thereis no evidence of risk in later trimesters, but animal studies
have shown an adverse effect on the fetus; or (2)human studies are
lacking, but animal studies have failed to show a risk to the fetus.

Category C: No adequate &well-controlled studies have been
performed in pregnant women, but animal reproduction studies
are lacking orhave shown an adverse effect on the fetus. Potential
benefit may warrant use of the drug in pregnant womendespite
potential risk.
Pain control of the entire primary dentition can be achieved with
approximately two cartridges of local anesthetic.The most
recommended drug in this case is:
A. 3% mepivicaine.
B. 2% lidocaine + epinephrine.
C. 2% mepivicaine + levonordephrine.
D. 4% articaine + epinephrine.
correct answer : (B)2% lidocaine + epinephrine.
Pain control for the entire primary dentition can be achieved with
approximately two cartridges of local anesthetic.In the smaller child
patient, there is rarely a compelling need to administer a 1.8 ml
volume of local anesthetic inany one injection. As a rule, the
pediatric dentist administers anesthetic without vasoconstrictor
only whentreatment is limited to one quadrant. If treatment
extends to two or more quadrants in one visit, a vasopressor-

containing local anesthetic is selected. In many instances, death
resulted when a total of 5, 6, or 7 cartridges ofanesthetic without
vasoconstrictor had been administered.
The maximum recommended dose by the FDA oflidocaine with or
without epinephrine is 3.2 mg/lb or 7.0 mg/kg of body weight for
the adult and pediatric patient.
All of the following local anesthetics can be used with a patient
taking tricylic antidepressants except one. Which is the exception?
A. Lidocaine with 1:100,000 epinephrine
B. Mepivicaine with 1:20,000 levonordefrin
C. Bupivicaine with 1:200,000 epinephrine
D. Prilocaine with 1:200,000 epinephrine
correct answer : (B)Mepivicaine with 1:20,000 levonordefrinT
Tricyclic Antidepressants (TCAs) may enhance the cardiovascular
actions of exogenously administeredvasopressors. This
enhancement is approximately fivefold to tenfold with
levonordefrin and noreprinephrine, but isonly twofold with
epinephrine and phenylephrine. Administration of noreprinephrine
