Question 1

Ludwig's angina is an aggressive cellulitis involving which of the following?

A) Mandible
B) Submandibular, sublingual, and submental spaces
C) Cavernous sinus
D) Masticator space
E) Orbit

Answer 1

B
Submandibular, sublingual, and submental spaces. Ludwig's angina is an aggressive cellulitis involving the bilateral sublingual, submandibular, and submental spaces that can spread down into the neck via the parapharyngeal spaces.

Question 2

The injection site for the _________ block is in the infratemporal region below the insertion of the lateral pterygoid muscle at the anterior aspect of the condylar neck.

A) palatine
B) greater palatine
C) standard inferior alveolar
D) Gow-Gates mandibular nerve
E) Akinosi mandibular nerve

Answer 2

D
Gow-Gates mandibular nerve. The injection site for the Gow-Gates mandibular nerve block is higher than that of the standard inferior alveolar block. In the Gow-Gates block, the needle tip is placed in the infratemporal region below the insertion of the lateral pterygoid muscle at the anterior aspect of the condylar neck.

Question 3

What kind of radiograph is used to detect occlusal caries, interproximal caries, overhanging restoration margins, and loss of alveolar bone height?

A) Occlusal radiograph
B) Panoramic radiograph
C) Periapical radiograph
D) Arthrography
E) Bitewing radiograph

Answer 3

E
Bitewing radiograph. Bitewing radiographs are useful in the detection of occlusal caries, interproximal caries, recurrent caries under old restorations, overhanging restoration margins, and loss of alveolar bone height.

Question 4

LeFort fractures fall into one of three basic patterns and involve _____________________.

A) the nasal septum
B) the mandible
C) several bones of the mid and upper face
D) the orbit
E) the skull

Question 5

A ________ fracture is a break in the bone that does not involve the skin externally or mucous membrane internally.

A) compound
B) complex
C) facial
D) simple
E) mandibular

Question 6

If an infection of alveolar bone is not treated, the infection may spread to tertiary sites, including _________________________.

A) soft tissues
B) external skin
C) superficial fascia
D) submandibular region
E) all of the above

Question 7

The site of an injection for a nasopalatine block is _____________.

A) A point midway between the gingival crest of the tooth and the midline palatal raphe
B) The mouth of the infraorbital canal
C) The mouth of the greater palatine canal
D) The mouth of the incisive canal immediately posterior to the central incisor teeth
E) The point where the posterior superior alveolar nerve enters the foramen on the infratemporal surface of the maxilla

Question 8

What kind of radiograph provides a view of crowns, roots, alveolar bone, and surrounding bony structures and may enable detection of periodontal disease, foreign bodies, and impacted third molars?

A) Bitewing radiograph
B) Periapical radiograph
C) Occlusal radiograph
D) Fluoroscope
E) Conventional tomograph

Question 9

Generally, mandibular dentition in an adult is anesthetized with ________________.

A) a nerve block
B) local infiltration
C) topical anesthetic
D) intraorbital injection
E) posterior superior alveolar block

Question 10

Anesthesia that blocks a main nerve and numbs several teeth is called ________________.

A) local infiltration
B) topical
C) nerve block
D) general anesthesia
E) infraorbital block
