1. A 24-year-old patient presents with a severely impacted
mandibular third molar. Panoramic imaging demonstrates the roots
are closely associated with the inferior alveolar canal. Which
complication is most specifically associated with surgical removal of
this tooth?
A. Greater palatine nerve injury
B. Inferior alveolar nerve injury
C. Infraorbital nerve injury
D. Mental nerve injury
Answer: B. Inferior alveolar nerve injury
Rationale: The mandibular third molar roots frequently have an
intimate anatomical relationship with the inferior alveolar canal.
Surgical manipulation, root displacement, or excessive bone removal
in this region can injure the inferior alveolar nerve, producing altered
sensation of the lower lip, chin, and mandibular teeth. Lingual nerve
injury is another important complication of mandibular third-molar
surgery, but the radiographic relationship described specifically raises
concern for inferior alveolar nerve injury.
1
,2. A patient develops persistent numbness of the lower lip and chin
immediately after mandibular third-molar extraction. Which nerve
was most likely injured?
A. Lingual nerve
B. Long buccal nerve
C. Inferior alveolar nerve
D. Mental nerve proximal to the mandibular foramen
Answer: C. Inferior alveolar nerve
Rationale: The inferior alveolar nerve supplies sensation to the
mandibular teeth and, through its mental branch, the lower lip and
chin. Injury proximal to the mental foramen can therefore produce
anesthesia or paresthesia involving both the lower lip and chin.
Lingual nerve injury primarily affects sensation of the anterior two-
thirds of the tongue and lingual gingiva.
3. During extraction of a mandibular third molar, the surgeon is
particularly concerned about injury to a nerve located lingual to the
mandibular third-molar region. Which nerve is this?
A. Facial nerve
B. Lingual nerve
C. Infraorbital nerve
D. Buccal branch of the facial nerve
Answer: B. Lingual nerve
Rationale: The lingual nerve courses close to the lingual cortical plate
in the mandibular third-molar region and can therefore be injured
during flap elevation, bone removal, or instrumentation. Injury can
cause altered taste and sensation involving the anterior two-thirds of
the tongue as well as sensory changes of the lingual gingiva.
2
,4. A patient presents with a mandibular third molar that is partially
erupted, surrounded by inflamed soft tissue, and associated with
pain and foul taste. What is the most likely diagnosis?
A. Dry socket
B. Pericoronitis
C. Osteomyelitis
D. Acute apical periodontitis
Answer: B. Pericoronitis
Rationale: Pericoronitis is inflammation of the soft tissues
surrounding a partially erupted tooth, particularly mandibular third
molars. Food debris and bacteria can accumulate beneath the
operculum, producing pain, swelling, halitosis, and sometimes trismus
or systemic symptoms.
5. Which finding most strongly suggests progression of odontogenic
infection into a potentially life-threatening deep fascial space
infection?
A. Mild localized gingival erythema
B. Small vestibular abscess without systemic symptoms
C. Floor-of-mouth elevation with dysphagia and respiratory difficulty
D. Mild postoperative tenderness
Answer: C. Floor-of-mouth elevation with dysphagia and
respiratory difficulty
Rationale: Floor-of-mouth elevation, dysphagia, drooling, tongue
elevation, and respiratory compromise suggest involvement of the
submandibular, sublingual, and/or submental spaces, as occurs in
Ludwig angina. Airway compromise is the immediate priority. Such
patients require urgent airway assessment and management together
with appropriate treatment of the infection.
3
, 6. Ludwig angina classically involves which combination of spaces?
A. Buccal and canine spaces
B. Sublingual, submandibular, and submental spaces
C. Pterygomandibular and temporal spaces only
D. Infraorbital and canine spaces only
Answer: B. Sublingual, submandibular, and submental spaces
Rationale: Ludwig angina is a rapidly progressive cellulitis involving
the bilateral submandibular, sublingual, and submental spaces.
Because swelling can elevate and posteriorly displace the tongue,
airway obstruction is a major concern.
7. A patient with an odontogenic infection develops fever,
tachycardia, malaise, progressive facial swelling, and difficulty
swallowing. What should be the surgeon's immediate priority?
A. Schedule routine extraction one week later
B. Obtain cosmetic facial photographs
C. Assess and secure the airway while initiating appropriate infection
management
D. Prescribe analgesics alone
Answer: C. Assess and secure the airway while initiating
appropriate infection management
Rationale: In severe odontogenic infections, airway compromise can
progress rapidly. Airway assessment and stabilization take priority
over definitive dental treatment. Drainage and elimination of the
odontogenic source are also essential, with antimicrobial therapy used
when clinically indicated.
