Question 1 of 10

A patient presents with a transverse maxillary deficiency, bilateral posterior crossbite, and difficulty chewing. Which referral pathway is most appropriate when the discrepancy appears skeletal rather than dental?

Refer for coordinated orthodontic and maxillofacial evaluation

Widen posterior crowns restoratively because increased crown width corrects the maxillary skeletal deficiency

Perform selective occlusal adjustment because removing cusp contacts expands the underlying maxillary arch

Extract posterior teeth before specialist evaluation because transverse discrepancies require space reduction

Question 2 of 10

A smoker with previously treated periodontitis requests implant placement. Current examination shows recurrent bleeding pockets and poor plaque control around several teeth. What should occur before elective implant placement?

Extract all periodontally involved teeth first

Stabilize periodontal disease and improve plaque control

Proceed with implant placement as planned

Prescribe prophylactic antibiotics before placement

Question 3 of 10

A root-treated premolar develops an isolated narrow 9-mm periodontal pocket and pain on biting. The coronal restoration is intact, and no generalized periodontal disease is present. Which condition should be suspected?

Recurrent coronal caries

Generalized periodontitis

Vertical root fracture

Isolated occlusal trauma

Question 4 of 10

A 32-year-old develops progressive chin deviation, a new unilateral posterior open bite, and worsening facial asymmetry over one year. Previous photographs show a previously symmetrical face. What is the most appropriate next step?

Refer for structural pathology assessment

Begin orthodontic alignment immediately

Observe without further investigation

Perform restorative equilibration immediately

Question 5 of 10

An adult has a long-standing facial asymmetry, unilateral posterior crossbite, and mandibular dental midline deviation that remains present when the mandible is guided into centric relation. What is the most appropriate next step?

Refer for combined skeletal assessment

Perform selective occlusal adjustment only

Observe without further assessment

Reshape crowns to mask asymmetry

Question 6 of 10

Intraoral photograph showing irregular white pseudomembranous plaques involving the posterior oral cavity.

A patient using an inhaled corticosteroid develops oral burning and altered taste. The intraoral appearance is shown. The visible material can be gently wiped away. Which diagnosis is most likely?

Reticular oral lichen planus

Oral hairy leukoplakia

Pseudomembranous oral candidiasis

Homogeneous oral leukoplakia

Question 7 of 10

During crown preparation, a dentist inadvertently removes enamel from the adjacent healthy tooth. The defect is minor and immediately repairable. What is the most appropriate professional response?

Disclose the incident, document it, and explain follow-up

Observe the tooth, disclose only if symptoms develop

Tell the assistant, document it, and continue treatment

Repair the area, document it, and avoid disclosure

Question 8 of 10

A manufacturer offers a dentist a substantial commission for recommending a particular home-care device to every patient. Comparable alternatives are available. What is the most appropriate ethical approach?

Conceal the commission because financial arrangements are unrelated to patient decisions

Charge higher fees for alternative products to encourage the commissioned recommendation

Base recommendations on patient need and disclose relevant financial incentives

Recommend the product routinely because receiving a commission does not affect advice

Question 9 of 10

A 3-year-old completely avulses a maxillary primary central incisor during a fall. The socket is empty and there are no other serious injuries. What is the appropriate management of the avulsed primary tooth?

Do not replant the tooth

Store in milk temporarily

Replant with rigid splinting

Replant and splint immediately

Question 10 of 10

During in-office bleaching, a patient suddenly reports intense burning of the gingiva adjacent to one tooth. What is the most appropriate immediate response?

Continue treatment and shorten the remaining exposure

Stop treatment and inspect the protective barrier

Increase peroxide concentration to finish more quickly

Administer local anesthetic and continue bleaching
