Question 1

Which radiographic technique is most appropriate for detecting proximal caries in posterior teeth?

Accepted Answer

Bitewing radiograph

Answer

Bitewing radiographs provide a clear image of the proximal surfaces of posterior teeth from the amelocemental junction to the alveolar crest, making them optimal for proximal caries detection.

Question 2

An electric pulp tester (EPT) primarily tests:

Accepted Answer

Pulp neural integrity

Answer

The EPT tests the integrity of A-delta nerve fibres within the pulp by applying an electrical stimulus; a response indicates neural function but does not assess pulp vitality (vascularity).

Question 3

The ideal occlusal scheme for a full arch implant-retained prosthesis is:

Accepted Answer

Mutually protected occlusion

Answer

Mutually protected occlusion (anterior guidance protects posteriors in excursions; posteriors protect anteriors in ICP load) is the preferred scheme for implant-supported prostheses to minimise lateral forces on implants.

Question 4

Under the GDC Standards for the Dental Team, which duty is defined as 'putting patients' interests first'?

Accepted Answer

Patient-centred care

Answer

GDC Standard 1 'Put patients' interests first' encompasses the concept of patient-centred care, ensuring decisions are made with the patient's wellbeing as the primary consideration.

Question 5

In restorative dentistry, the 'biologic width' refers to:

Accepted Answer

The combined dimension of junctional epithelium and connective tissue attachment

Answer

Biologic width (approximately 2 mm) is the combined height of junctional epithelium (~1 mm) and supracrestal connective tissue (~1 mm); violation by restorative margins causes inflammation and bone loss.
