Q: An example of a natural tooth-supported fixed partial denture is:
- bilateral: supported by one or more natural teeth at each end
- cantilever: a pontic supported by one or more teeth at one end only
- Maryland bridge: resin-bonded retainer attached to etched enamel with little or no removal of tooth structure
- both A and C
- all of the above
A: all of the above

Q: A nonabrasive dentifrice is indicated to prevent the possibility of abrasion of the prosthesis surfaces and when areas of root exposure are on abutment teeth. A fluoride-containing dentifrice is important for protection of remaining tooth surfaces, particularly exposed cementum; acidulated fluoride preparations are contraindicated for porcelain and composite restorations.
- Both statements are true
- Both statements are false
- The first statement is true and the second statement is false
- The first statement is false and the second statement is true
A: Both statements are true

Q: Margins of restorations may provide slight irregular areas for retaining biofilm and require daily attention. The gingival surfaces of the pontics and beneath the connectors are particularly prone to biofilm retention.
- Both statements are true
- Both statements are false
- The first statement is true and the second statement is false
- The first statement is false and the second statement is true
A: Both statements are true

Q: The components of a complete denture are:
- denture base
- three surfaces: impression, polished, and occlusal
- acrylic resin, composite resin, or porcelain teeth
- both A and C
- A, B, and C
A: A, B, and C

Q: Denture biofilm is composed predominantly of Gram-positive cocci, rods, and filamentous forms of bacteria in an intermicrobial substance. Biofilm serves as a matrix for calculus formation and stain accumulation when the denture is not cleaned.
- Both statements are true
- Both statements are false
- The first statement is true and the second statement is false
- The first statement is false and the second statement is true
A: Both statements are true

Q: A hypochlorite solution (household bleach) can be used as a chemical solution for denture immersion. Which of the following is true regarding this solution?
- Active ingredient is a dilute sodium hypochlorite with bleaching properties
- Mode of action is to loosen stains and deposits
- Solution can corrode metal parts
- All of the above
A: All of the above

Q: What is the purpose of a complete overdenture?
- Helps to preserve bone, improving retention of a denture
- Allows the remaining teeth to bear occlusal pressures, thereby reducing the pressure placed on edentulous areas
- Improves stability and retention of the denture
- Improves the patient's tactile and proprioceptive senses by having the periodontal ligament present
- All of the above
A: All of the above

Q: Which is true of denture pastes, powders, and toothpastes?
- Calcium carbonate is the active ingredient
- Mode of action is mechanical removal of biofilm and stains
- Can abrade the plastic resin denture base and acrylic teeth
- A and B
- A, B, and C
A: A, B, and C

Q: Which of the following is true with regard to performing an intraoral examination on a patient with dentures?
- Soft tissue examination and oral cancer screening are recommended at least yearly for all patients
- Refer any concerns with appliance for evaluation
- Record oral changes that may be indicative of systemic disease and refer for evaluation
- Inform patient to seek care when experiencing any oral changes or concerns with a prosthesis
- All of the above
A: All of the above

Q: Your patient Mr. Jones wants all of his teeth extracted and a denture made. Mr. Jones does not want you to clean his remaining teeth because they are already “dead” due to root canals. You respond to his suggestion by saying that:
- you will cancel his recare appointment because there is no need to do a cleaning
- you will clean his remaining teeth because a tooth with a root canal can be saved and used for the overdenture
- you will clean his remaining teeth because saving any teeth will improve retention of the denture
- both B and C
- none of the above
A: both B and C

Q: Your patient Mrs. Johnstone has a full upper maxillary denture and a mandibular partial. Mrs. Johnstone informs you at her recare appointment that she never removes her denture or partial because she doesn't want anyone to see her without it. You respond:
- keeping the denture and partial in will help to prevent tissue irritation
- keeping the denture and partial in will increase irritation to the mucosa
- the denture and partial should be kept out to dry to help decrease the accumulation of bacteria for at least 6 to 8 hours each day
- rinsing the denture and partial each day with water will remove biofilm accumulation
A: keeping the denture and partial in will increase irritation to the mucosa

Q: Your patient Mr. Thompson has an upper and lower partial. You notice that Mr. Thompson has a lot of plaque and deposit on the partials. Mr. Thompson explains that he rinses off the partials each night after removing them, so he is surprised that there is a lot of plaque and deposit on the partials. What OHI would help Mr. Thompson?
- Mr. Thompson should use his toothbrush to clean the partials
- Mr. Thompson should soak the partials in hot water to remove the plaque
- Mr. Thompson should use an electric toothbrush to remove the plaque
- Mr. Thompson should use a clasp brush to clean the partials
A: Mr. Thompson should use a clasp brush to clean the partials

Q: Your patient Mrs. Olson has three posterior molars that have full gold crowns, and she is missing her premolars and has an upper and lower partial denture. During the assessment you notice quite a bit of recession along the gingival margin and plaque accumulation. What preventative measure would you recommend?
- Better gingival brushing but no topical fluoride since the molars have crowns
- Better gingival brushing and a topical fluoride
- Better gingival brushing and soaking the partial in a light bleach cleaning solution
- None of the above
A: Better gingival brushing and a topical fluoride

Q: Mr. Kennedy has come into the office for his 6-month recare appointment. He informs you that he is tired of wearing his partials and he would like to just have the DDS extract the rest of the teeth and make a denture. Upon looking at his radiographs you see that the bone and support is excellent in the remaining teeth. What would you say to Mr. Kennedy in response to his request?
- A full denture requires more patient care than natural teeth
- Full dentures have excellent retention
- Full dentures are just as good as natural teeth
- Full dentures require fewer dental visits
- Natural teeth should be retained for as long as possible
A: Natural teeth should be retained for as long as possible

Q: Which of the following has been associated with biofilm on dentures?
- Yeast
- Candida albicans
- Gram-positive cocci
- Filamentous forms of bacteria
- All of the above
A: All of the above
