Free DDS Doctor of Dental Surgery Trivia Questions and Answers — Questions and Answers
Question 1: Which of the following should you do before taking out tooth 24?
- Warfarin (Coumadin®) should be discontinued the morning before procedure.
- Clarithromycin (Biaxin®) 500 milligrams should be taken 30 minutes to 60 minutes before procedure.
- No antibiotic administration is required.
- Amoxicillin 2 grams should be taken 30 minutes to 60 minutes before procedure. (Correct answer)
Correct answer: Amoxicillin 2 grams should be taken 30 minutes to 60 minutes before procedure.
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?
- Panoramic (Correct answer)
- Bitewing
- Periapical
- Bitewing
Correct answer: Panoramic
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?
- Wrap in a wet napkin
- Put in a cup of milk
- Place back into the sockets (Correct answer)
- Place under the tongue
Correct answer: Place back into the sockets
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?
- Make hepatitis C vaccinations available. (Correct answer)
- Provide personal protective equipment.
- Implement the use of standard precautions.
- Establish an exposure control plan.
Correct answer: Make hepatitis C vaccinations available.
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?
- Copolymer
- Calcium hydroxide
- Zinc oxide eugenol (Correct answer)
- Glass ionomer
Correct answer: Zinc oxide eugenol
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.
Question 6: After a 40-pack-year smoking history, a patient expresses a wish to quit. Except for one, all of the following would be proper actions. Which of these is an EXCEPTION?
- Recommend hypnosis
- Prescribe a nicotine (NicoDerm-CQ®) patch
- Recommend use of a smokeless tobacco (Correct answer)
- Recommend nicotine (Nicorette®) chewing gum
Correct answer: Recommend use of a smokeless tobacco
Recommending smokeless tobacco is not a proper action for a patient wishing to quit smoking. While smokeless tobacco eliminates some risks associated with combustion, it still contains nicotine and numerous carcinogens, posing significant health risks including oral cancer, periodontal disease, and nicotine addiction. The goal of tobacco cessation counseling is complete abstinence from all tobacco products.
Question 7: Which sort of study gives the strongest evidence for making judgments about patient treatment?
- Systematic review (Correct answer)
- Evidence summary
- Cohort
- Case control
Correct answer: Systematic review
In the hierarchy of evidence, systematic reviews and meta-analyses provide the strongest evidence for clinical decision-making. They synthesize findings from multiple high-quality primary studies (like randomized controlled trials) on a specific topic, reducing bias and increasing the reliability and generalizability of the conclusions. This comprehensive approach offers the most robust basis for judgments about patient treatment.
