Orofacial 2 Final Questions and Correct Answers
(100% COMPLETE ANSWERS) ALREADY GRADED A+
*The posterior superior alveolar artery and its branches supply the
A. maxillary posterior teeth and periodontium
B. mandibular posterior teeth and periodontium
C. sternocleidomastoid muscle and thyroid gland
D. temporalis muscle and parotid salivary gland
maxillary posterior teeth and periodontium
*Which of the following descriptions concerning the pterygoid plexus of veins is
CORRECT?
A. Located around the infrahyoid muscles Protects the superficial temporal
artery
C. Drains the maxillary and mandibular dental arches
D. Can be pierced resulting in xerostomia
Drains the maxillary and mandibular dental arches
Which structures should the dental profession AVOID inadvertently injecting?
a. Major blood vessels only
b. Glandular tissue only
c. Major blood vessels and muscular tissue
d. Glandular tissue and muscular tissue
e. Major blood vessels and glandular tissue
,Major blood vessels and glandular tissue;
the dental professional must know the location of certain adjacent soft tissue
structures, such as major blood vessels and glandular tissue, so as to avoid
inadvertently injecting them.
The skull bones involved in local anesthetic administration by dental
professional prior to effective dental care are the maxilla, mandible, and
a. zygomatic bone.
b. palatine bones.
c. frontal bone.
d. ethmoid bone.
e. sphenoid bone.
palatine bones
the skull bones involved in local anesthetic administration by dental professional
prior to effective dental care are the maxilla, palatine bone, and mandible.
Which of the following is NEVER anesthetized during an administration of the
greater palatine block?
a. Pulpal anesthesia
b. Lingual gingival tissue
c. Hard palate tissue
d. Soft palate tissue
e. Hard and soft palate tissue
Pulpal anesthesia
because the greater palatine block does not provide pulpal anesthesia of the area
teeth, the use of other blocks may be indicated
Which nerve branches are anesthetized before MOST dental procedures?
a. Trigeminal nerve
b. Facial nerve
,c. Ophthalmic nerve
d. Glossopharyngeal nerve
e. Hypoglossal nerve
Trigeminal nerve;
branches of the trigeminal nerve are anesthetized before most dental procedures
Which of the following are NOT considerations that need to be followed when
working with a patient with an oral infection?
a. Will need less amounts of local anesthetic agent
b. Never inject directly through an abscess, cellulitis, or osteomyelitis
c. Wait for local anesthetic agent to take effect
d. Effectiveness of local anesthetic agent is reduced
e. Inject from posterior to anterior within a quadrant
Will need less amounts of local anesthetic agent;
the effectiveness of local anesthetic agents is greatly reduced when administered
adjacent to areas of infection, so additional amounts of local anesthetic agent
may be needed keeping the maximal recommended dosage always in mind for
each patient.
What structure can be punctured if the dental professional does NOT keep the
needle in contact with the bone at the roof of the infraorbital foramen to
prevent overinsertion when administering an injection in that area?
a. Maxillary sinus
b. Pterygoid plexus of veins
c. Maxillary artery
d. Orbit
e. Frontal sinus
Orbit;
keeping the needle in contact during an infraorbital block with the bone at the
, roof of the infraorbital foramen prevents overinsertion and possible puncture of
the orbit.
Which of the following local anesthetic blocks if INCORRECTLY administered can
cause transient facial paralysis?
a. Anterior superior alveolar block
b. Mental block
c. Infraorbital block
d. Inferior alveolar block
e. Posterior superior alveolar block
Inferior alveolar block
transient facial paralysis can occur due to injection into the parotid salivary gland
during an incorrectly administered inferior alveolar block due to presence of facial
nerve or seventh cranial nerve within the gland.
What is the junction that occurs between two neurons or between a neuron and
an effector organ, where neural impulses are transmitted?
a. Synapse
b. Ganglion
c. Neuron
d. Nerve
e. Anastomosis
Synapse
a synapse is the junction between two neurons or between a neuron and an
effector organ, where neural impulses are transmitted.
In which of the following conditions does the patient feel excruciating short-
term pain when facial trigger zones are touched or even when speaking or
masticating, setting off associated brief muscle spasms or tics the area?
a. Facial paralysis
b. Bell palsy
