Question 1

Which of the following should you do before taking out tooth 24?

Accepted Answer

Amoxicillin 2 grams should be taken 30 minutes to 60 minutes before procedure.

Answer

Tooth 24 is a mandibular incisor. Antibiotic prophylaxis is indicated for patients at high risk of infective endocarditis undergoing dental procedures that involve manipulation of gingival tissue or the periapical region of teeth. Amoxicillin 2 grams orally 30-60 minutes before the procedure is the standard prophylactic regimen for such patients, according to American Heart Association guidelines.

Question 2

Which of the following screening radiographs would be most useful in determining a fracture of the mandible?

Accepted Answer

Panoramic

Answer

A panoramic radiograph provides a broad, comprehensive view of the entire mandible, maxilla, and associated structures. This wide field of view makes it an excellent screening tool for detecting mandibular fractures, as it can show the extent and location of breaks that might be missed on smaller, localized films like periapicals or bitewings.

Question 3

Reimplantation is preferred. After avulsion, how can permanent teeth be effectively shielded?

Accepted Answer

Place back into the sockets

Answer

For an avulsed permanent tooth, the most effective way to preserve its viability and maximize the chances of successful reimplantation is to immediately place it back into its socket. This maintains the periodontal ligament cells in their natural environment, which is critical for healing. If immediate replantation isn't possible, storage in milk or saline is recommended as a temporary measure.

Question 4

OSHA's bloodborne pathogen standard mandates healthcare. EXCEPT for one, employers must perform all of the following. Which is it? WHAT IS THE EXCEPTION?

Accepted Answer

Make hepatitis C vaccinations available.

Answer

OSHA's Bloodborne Pathogens Standard mandates employers to provide hepatitis B vaccinations to employees at risk of occupational exposure. However, there is currently no vaccine available for hepatitis C, so employers cannot be mandated to make it available. The other options (providing personal protective equipment, implementing standard precautions, and establishing an exposure control plan) are all required by the standard.

Question 5

Which base or liner could hinder a resin composite restoration from polymerizing?

Accepted Answer

Zinc oxide eugenol

Answer

Zinc oxide eugenol (ZOE) contains eugenol, which is known to inhibit the polymerization of resin-based materials. Eugenol can interfere with the free radical polymerization process of composite resins, leading to incomplete curing, reduced bond strength, and compromised restoration integrity. Therefore, ZOE should be avoided as a base or liner under composite restorations.
