Restorative Dentistry Flashcards

What is the purpose of a diagnostic wax-up before complex restorative treatment?

Answer: To plan and communicate the intended outcome before tooth preparation

A diagnostic wax-up allows the clinician and patient to visualise, plan, and communicate the intended restorative outcome, guiding preparation and temporary fabrication.

According to GDC Standards, how often should patient records be updated in a dental practice?

Answer: At every appointment

GDC Standards require dental professionals to update records at every clinical contact to ensure accurate, contemporaneous documentation of care.

Which condition is most likely if a patient reports their crown 'feels high' immediately after cementation?

Answer: Premature occlusal contact on the restoration

A 'high' bite sensation after crown cementation indicates a premature occlusal contact that needs articulating paper assessment and selective adjustment.

What is the recommended minimum thickness of porcelain for adequate strength in a posterior all-ceramic crown?

Answer: 1.5 mm

A minimum of 1.5 mm of ceramic is required posteriorly to provide adequate fracture resistance under occlusal loading forces.

Which radiographic technique minimises geometric distortion in periapical views?

Answer: Paralleling technique

The paralleling technique, where the film/sensor is parallel to the tooth and the beam is perpendicular to both, minimises geometric distortion and foreshortening.

What is the most appropriate management of a cracked tooth with reversible pulpitis and no periodontal involvement?

Answer: Cuspal coverage restoration (e.g., onlay or crown)

Cuspal coverage protects the tooth from further crack propagation, and if pulpitis remains reversible, endodontic treatment may be avoided.
