ADC Written Exam Practice Questions - ADC Written Examination (Dentists) Exam - ADC Written Exam Practice Questions

Question 1

A 28-year-old presents with a small occlusal carious lesion on tooth 36 that is confined to enamel and dentine but has not yet cavitated radiographically on the proximal surface. The patient has good oral hygiene and a low caries risk. According to contemporary minimal-intervention principles taught in Australian dental programs, what is the most appropriate management of this early occlusal lesion?

Place a preventive resin restoration or seal the affected fissure after minimal caries removal Prepare a full-coverage stainless steel crown to prevent further breakdown Remove the entire occlusal surface and place an amalgam restoration Extract the tooth to eliminate the caries risk

Correct Answer:

Place a preventive resin restoration or seal the affected fissure after minimal caries removal

Question 2

When placing a posterior resin composite restoration, a candidate notes that the deepest portion of the proximal box lies more than 4 mm below the cavosurface margin. Which incremental placement strategy best limits polymerisation shrinkage stress and ensures adequate cure at the gingival floor?

Bulk-fill the entire cavity with a conventional microhybrid composite in one increment Fill the box with flowable composite to the cavosurface margin in a single application Place oblique increments no thicker than 2 mm and cure each separately, or use a validated bulk-fill material to the depth specified by the manufacturer Leave the gingival floor unfilled and restore only the occlusal portion

Correct Answer:

Place oblique increments no thicker than 2 mm and cure each separately, or use a validated bulk-fill material to the depth specified by the manufacturer

Question 3

A patient has a deep carious lesion on tooth 46 with no spontaneous pain; the tooth responds normally to cold and there are no periapical changes radiographically. During excavation you reach a point where further removal would likely expose the pulp. What is the most evidence-based approach in line with current vital pulp therapy concepts?

Complete the cavity by fully removing all stained dentine regardless of pulp exposure risk Place a temporary dressing and review in 12 months before any restoration Initiate root canal treatment immediately as the pulp is certainly necrotic Perform selective (partial) caries removal over the pulpal area, leaving firm affected dentine, then seal with a biocompatible liner and definitive restoration

Correct Answer:

Perform selective (partial) caries removal over the pulpal area, leaving firm affected dentine, then seal with a biocompatible liner and definitive restoration

Question 4

Which property of glass-ionomer cement makes it particularly useful for restoring cervical lesions in a patient with high caries risk and poor moisture control?

It bonds only through micromechanical etch-and-rinse adhesion It chemically bonds to tooth structure and releases fluoride, with relative tolerance of moisture during placement It has the highest wear resistance of all direct restorative materials It is radiolucent, allowing easy detection of recurrent caries

Correct Answer:

It chemically bonds to tooth structure and releases fluoride, with relative tolerance of moisture during placement

Question 5

A 55-year-old needs a full-coverage crown on a heavily restored, root-filled premolar 14 with limited remaining coronal tooth structure. To improve retention and protect the remaining structure, which feature is most important to incorporate into the restorative plan?

Maximum taper of the preparation walls to ease seating A wide, flat shoulder margin extending well subgingivally on all surfaces A 1.5-2 mm ferrule of sound tooth structure encircled by the crown margin Removal of all remaining dentine to seat a post as deeply as possible

Correct Answer:

A 1.5-2 mm ferrule of sound tooth structure encircled by the crown margin
