Free DMD Restorative Procedures & Prosthodontics Questions and Answers

Question 1

What is the purpose of a dental filling?

Accepted Answer

To restore a decayed tooth

Answer

The primary purpose of a dental filling is to restore a tooth that has been damaged by decay (a cavity). After the decayed portion is removed, the filling material is used to fill the void, restoring the tooth's original shape, function, and integrity. This prevents further decay and protects the tooth from sensitivity or fracture.

Question 2

Which material is commonly used for aesthetic anterior restorations?

Accepted Answer

Composite resin

Answer

Composite resin is the material of choice for aesthetic anterior restorations due to its tooth-colored appearance and ability to bond directly to the tooth structure. It can be matched to the natural shade of the patient's teeth, making it virtually invisible, and is ideal for repairing chips, cracks, or cavities in the front teeth where aesthetics are paramount.

Question 3

What is the main function of a dental crown?

Accepted Answer

To cover and protect a weakened tooth

Answer

A dental crown, often referred to as a "cap," is a custom-made restoration that completely covers the entire visible portion of a tooth above the gum line. Its main function is to restore a severely damaged, fractured, or weakened tooth, providing strength, protection, and restoring its original shape, size, and function. This prevents further breakdown and extends the tooth's lifespan.

Question 4

What is a bridge used for in prosthodontics?

Accepted Answer

To replace missing teeth

Answer

A dental bridge is a fixed prosthetic device used to replace one or more missing teeth by "bridging" the gap between existing teeth or implants. It consists of artificial teeth (pontics) held in place by crowns cemented onto the natural teeth or implants adjacent to the gap. This restores chewing function, maintains alignment, and improves aesthetics.

Question 5

Which condition is most likely to require full-mouth reconstruction?

Accepted Answer

Advanced tooth wear

Answer

Full-mouth reconstruction is a comprehensive treatment involving multiple dental procedures to restore the entire mouth. It is typically required for patients with extensive dental problems, such as advanced tooth wear (due to grinding or acid erosion), multiple missing teeth, severe decay, or bite problems. Mild conditions like discoloration or gingivitis would not necessitate such extensive treatment.
