Correct answer: The branch of dentistry dealing with the dental pulp and tissues surrounding the root — commonly root canal therapy
Endodontics focuses on the interior of the tooth (pulp) and root structures. Root canal treatment, the most common procedure, removes infected pulp tissue.
Question 2: What is the difference between a dental filling and an inlay?
- There is no difference
- A filling is placed directly; an inlay is fabricated in a lab and then cemented into the prepared cavity (Correct answer)
- Inlays are only temporary
- Fillings are made of gold only
Correct answer: A filling is placed directly; an inlay is fabricated in a lab and then cemented into the prepared cavity
Direct fillings are placed and shaped in the mouth. Inlays are custom-made in a lab from impressions and then bonded into the prepared cavity for a precise fit.
Question 3: What is a dental bridge?
- A tool used during exams
- A prosthetic that replaces one or more missing teeth by anchoring to adjacent natural teeth or implants (Correct answer)

Correct answer: A prosthetic that replaces one or more missing teeth by anchoring to adjacent natural teeth or implants
A dental bridge literally bridges the gap left by missing teeth, with pontics (artificial teeth) supported by crowns on the neighboring teeth (abutments).

Correct answer: To coat the chewing surfaces of back teeth with a protective barrier that prevents decay
Sealants are thin plastic coatings applied to the grooves of premolars and molars, preventing bacteria and food particles from settling in these decay-prone areas.
