Question 1 of 10

A 6-year-old has premature loss of a primary mandibular first molar. The adjacent primary second molar and canine are intact, and the permanent first molar has erupted. Which appliance is commonly appropriate when space maintenance is indicated?

Band-and-loop space maintainer

Lower lingual holding arch

Nance palatal holding appliance

Distal-shoe space maintainer

Question 2 of 10

A primary molar has deep caries and clinical signs of irreversible pulpitis but no swelling, sinus tract, furcation radiolucency, or pathologic resorption. Which contemporary treatment option may be considered in selected cases?

Complete pulpotomy with an appropriate vital pulp protocol

Pulpectomy automatically in every vital tooth displaying irreversible pulpitis symptoms

Indirect pulp treatment despite established signs of irreversible pulpal inflammation

Extraction automatically despite favorable restorability and absence of infection

Question 3 of 10

An 8-year-old has a persistent digit-sucking habit, increased overjet, and an anterior open bite. The child is motivated to stop. What is the most appropriate initial management principle?

Extract permanent incisors to reduce the overjet

Ignore the habit until permanent dentition is complete

Begin positive habit counseling and behavioral cessation support

Refer immediately for surgical correction of the open bite

Question 4 of 10

During root canal irrigation, the clinician feels resistance while advancing the irrigation needle toward working length. Which technique best reduces the risk of irrigant extrusion?

Wedge the needle tightly before delivering irrigant under positive pressure

Inject rapidly because higher pressure improves apical irrigant penetration

Extend the needle beyond the apex to disinfect periapical tissues

Keep the needle loose and deliver irrigant gently

Question 5 of 10

A patient completes vital tooth whitening and wants two anterior composite veneers replaced immediately because their shade no longer matches. When is final shade matching most appropriately performed?

By increasing composite opacity without waiting for the bleached enamel shade to stabilize

Immediately after bleaching while natural tooth color is still undergoing post-treatment stabilization

After post-whitening color stabilization before definitive replacement

By replacing the composites with full crowns before evaluating the final stabilized tooth shade

Question 6 of 10

An adult presents with a severe anterior open bite extending from canine to canine and reports difficulty incising food. There is substantial vertical skeletal discrepancy on facial examination. What is the most appropriate general-dentist action?

Perform selective occlusal grinding to eliminate the vertical jaw discrepancy

Arrange orthodontic and maxillofacial assessment of the skeletal deformity

Observe without referral because open bite treatment is primarily cosmetic

Lengthen the anterior teeth restoratively to close the entire skeletal open bite

Question 7 of 10

During treatment, a patient with known epilepsy develops a generalized tonic-clonic seizure. The convulsions continue beyond five minutes without recovery of consciousness. What is the most appropriate response?

Restrain the patient's limbs firmly until all generalized motor activity stops completely

Protect the patient, support airway and oxygenation, and activate emergency services

Place an object between the teeth to prevent tongue injury during convulsions

Continue dental treatment once movement lessens without arranging urgent medical assessment

Question 8 of 10

A 6-year-old receives a stainless steel crown on a primary molar after extensive multisurface caries. Which feature is a principal reason for selecting this restoration?

It provides durable full-coronal coverage for extensively damaged primary teeth

It permanently eliminates future caries risk without additional preventive management

It requires pulpotomy in every tooth before full-coronal restoration can be placed

It provides superior tooth-colored esthetics for visible anterior primary teeth

Question 9 of 10

A mandibular incisor has increasing mobility because of severe periodontal attachment loss. There is no fremitus or excessive occlusal contact. Which factor should primarily determine whether the tooth can be retained?

Permanent splinting alone because stabilization eliminates the need for periodontal disease control

Mobility grade alone because any progressive mobility makes periodontal treatment futile

Occlusal adjustment alone because reducing contact predictably regenerates lost periodontal attachment

Remaining periodontal support, disease control, function, and maintainability

Question 10 of 10

A patient with otherwise uncomplicated Stage II periodontitis asks for antibiotics instead of subgingival instrumentation. There is no acute spreading infection or systemic illness. What is the most appropriate response?

Extract affected teeth without therapy

Use mechanical therapy without routine antibiotics

Delay treatment until symptoms develop

Use systemic antibiotics without instrumentation
