Question 1 of 10

A 40-year-old with periodontitis has approximately 60% radiographic bone loss at the most affected tooth. Previous radiographs are unavailable, and the patient does not smoke and has no diabetes. Using the bone-loss-to-age ratio as indirect evidence of progression, which grade is most appropriate?

Grade C progression

Grade A progression

Grade B progression

Grade cannot be assigned

Question 2 of 10

Immediately after a posterior superior alveolar nerve block, a patient develops rapidly enlarging unilateral cheek swelling and bruising without urticaria, wheezing, or airway symptoms. What is the most appropriate immediate local management?

Apply firm pressure and a cold compress

Give intramuscular epinephrine and continue monitoring

Massage the swelling firmly to disperse blood

Incise and drain the swelling immediately

Question 3 of 10

A patient is missing the mandibular left first and second molars. Natural teeth remain anterior and posterior to the bounded edentulous space, and there are no other missing teeth. Which Kennedy classification applies?

Kennedy Class II partially edentulous arch

Kennedy Class III partially edentulous arch

Kennedy Class I partially edentulous arch

Kennedy Class IV partially edentulous arch

Question 4 of 10

A 44-year-old has interdental clinical attachment loss of 3-4 mm at several nonadjacent teeth, radiographic bone loss confined to the coronal third at approximately 20%, probing depths no greater than 5 mm, and no teeth lost because of periodontitis. Which stage best describes the periodontitis?

Stage I periodontitis

Stage III periodontitis

Stage II periodontitis

Stage IV periodontitis

Question 5 of 10

A maxillary molar has poorly localized aching pain, but cold testing gives similar brief responses in all posterior teeth and percussion is negative. No definite lesion is visible radiographically. What is the most appropriate diagnostic approach before irreversible treatment?

Reassess until the source is localized

Prescribe antibiotics before further testing

Treat the most suspicious tooth endodontically

Extract the most heavily restored tooth

Question 6 of 10

Panoramic radiograph of a child showing erupted permanent teeth, retained primary teeth, and multiple developing unerupted permanent successors.

A healthy 9-year-old attends for routine assessment. The panoramic radiograph shown was obtained for a justified clinical indication. Which description best matches the developmental stage visible?

Normal mixed dentition for this age

Premature loss of all primary teeth

Delayed eruption of all permanent teeth

Complete permanent dentition for this age

Question 7 of 10

Frontal intraoral photograph demonstrating keratinized and nonkeratinized gingival tissues with a localized area of gingival recession.

A 39-year-old reports localized root sensitivity at a maxillary anterior tooth. Probing depths are 2 to 3 mm, and there is no interproximal clinical attachment loss. The buccal soft-tissue relationship is shown. According to the Cairo recession classification, how should this defect be classified?

Cairo RT2 recession defect

Unclassified gingival recession defect

Cairo RT3 recession defect

Cairo RT1 recession defect

Question 8 of 10

A 57-year-old has a persistent, well-demarcated velvety red patch on the floor of the mouth. It has no identifiable traumatic or inflammatory cause and remains unchanged after two weeks. What is the most appropriate next step?

Continue routine observation for months

Begin empirical antifungal therapy first

Review after another three months

Arrange prompt biopsy or referral

Question 9 of 10

A 74-year-old with high caries risk requires restoration of a non-load-bearing cervical root-surface lesion. The gingival margin is difficult to isolate completely from moisture, and esthetics are of moderate importance. Which direct restorative material is most appropriate?

Use indirect ceramic inlay restorative material

Use resin-modified glass-ionomer restorative material

Use conventional microhybrid resin-composite restorative material

Use high-copper dental amalgam restorative material

Question 10 of 10

During obturation of a properly prepared root canal, what is the principal role of endodontic sealer used together with a solid core material?

Reinforce the root enough to avoid coronal restoration

Sterilize residual infected tissue left after inadequate preparation

Fill minor discrepancies between the core and canal walls

Replace the solid core as the entire canal filling
