# Which of the following accounts for why endodontically treated posterior teeth are more susceptible to fracture than untreated ones?
A. Loss of moisture
B. Damaged coronal structure
C. Plastic deformation of the dentin
D. Loss of pulpal vitality
The correct answer is B. DAMAGED CORONAL STRUCTURE
Endodontically treated teeth have a decreased amount of coronal dentin due to the access preparation necessary for root canal treatment.
Loss of coronal dentin alters the internal architecture of the tooth, changing the dispersement of forces in the tooth.
The change to the internal architecture put the tooth at higher risk for fracture.

Dental treatment - Endodontic perforation
# Which of the following locations would a perforation demonstrate the BEST prognosis?
A. Floor of pulp chamber
B. Coronal 1/3 of root
C. Middle 1/3 of root
D. Apical 1/3 of root
The correct answer is D. Apical third of root.
Apical perforations occur through the apical foramen or the body of the root to form a new canal.
The more apical the perforation, the more favorable the prognosis for the tooth. (except for the coronal perforations)
A. Floor of pulp chamber
B. Coronal 1/3 of root

Least reliable sign of pulpal disease in primary teeth:
Q. Which of the following is the least reliable sign of pulpal disease in primary teeth?
A. Electronic pulp test
B. Spontaneous pain
C. Internal resorption
D. Furcal radiolucency
E. Swelling
The correct Answer is A. Electronic pulp test
Electronic pulp testing is very unreliable in primary teeth because the A fibers that are more easily stimulated by electricity appear late in pulpal maturity.
The accuracy of the pulp testing may also be affected by the patient's ability to describe their response to the stimuli, to which, pediatric patients are typically not as able to describe their experiences in a clinically relevant way.

Local anesthetic technique for Hemophilics:
# Which of the following is the preferred local anesthetic technique for hemophilics?
A. Nerve block
B. Supraperiosteal
C. Intraligamentary
D. Field block
The correct answer is C. Intraligamentary
In hemophilics, to avoid complications, Intraligamentary (an intraosseous technique) method of local infiltration technique is preferred. In this technique, the solution is deposited in depth of gingival sulcus. The needle should be inserted apically into the bone until resistance is met.
Local anesthetic with longest duration of action:
# In peripheral nerve block, which of the following local anesthetics has the longest duration of action?
A. Bupivacaine
B. Cocaine
C. Lignocaine
D. Prilocaine
A. Bupivacaine
B. Cocaine
C. Lignocaine
D. Prilocaine
The correct answer is A. BUPIVACAINE
Etidocaine (200 mins) followed by Bupivacaine (180 mins) are long acting anesthetics and this is due to their increased protein binding property.
