- 24 to 48 hours
- It will not begin if an oral irrigation system is used
A: 24 to 48 hours

Q: Your patient Mrs. Johnson came in for her 6-month recare appointment. She is surprised when you tell her that she has calculus on many of her teeth. Mrs. Johnson tells you that she never used to get as much calculus when she was younger. She asks you why this is happening because her home care is still the same—she brushes and flosses every day—and you respond:
- age has nothing to do with calculus formation
- maybe she should floss harder
- maybe she should brush harder
- incidence of calculus formation increases with age
A: incidence of calculus formation increases with age

Q: Your patient Mr. Jones wants to know what you think about the new bleaching toothpaste that has just come into the stores. He wants to buy some but he wants to know if it will be good for him or possibly harm his teeth. He asks you what he should do and you advise him:
- give the toothpaste a try and if there is any discomfort discontinue usage
- ask family and friends if they have had any problems with the product's usage
- buy the product and use just a small amount at first until you are used to it
- buy only products that contain the ADA seal of approval on the package
A: buy only products that contain the ADA seal of approval on the package

Q: Calculus occurs most frequently on:
- lingual surfaces of maxillary molars
- facial surfaces of maxillary molars
- lingual surfaces of maxillary incisors
- none of the above
A: facial surfaces of maxillary molars

Q: Which one of the following is an inorganic component of calculus?
- Desquamated epithelial cells
- Mucin from saliva
- Leukocytes
- Calcium
A: Calcium

Q: One of the main objectives in nonsurgical periodontal therapy is:
- to remove deposits and have biologically acceptable smooth surfaces
- to remove all deposits and pellicle formation
- to remove all biofilm and pellicle formation
- none of the above
A: to remove deposits and have biologically acceptable smooth surfaces

Q: Your patient James Olsen is in for his 6-month recare appointment. He informs you that he has been unable to remove the plaque from his upper and lower central incisors no matter how hard he tries. His health history states that he has areas of fluorosis and suspect caries on posterior molars. Which one of the following could make Mr. Olsen more susceptible to calculus formation?
- Pitted enamel
- Carious defects
- Both A and B
- None of the above
A: Both A and B

Q: Your patient Kathy is in for her recare appointment; she recently purchased some tartar-control toothpaste, and it seems to be working for her. She asks you, “How does it prevent tartar from forming?” You respond:
- it prevents the buildup of saliva
- it prevents pellicle formation
- it contains fluoride, which helps to prevent decalcification
- it contains pyrophosphate
A: it contains pyrophosphate

Q: Your patient Mrs. Jordan has come in for her 3-month recare appointment. You update her medical history, and she informs you that she has recently had another bout with kidney stones. After you access her dentition you inform her that you are finding a lot of new deposit and it is good that she came today. She is surprised because she brushes and flosses a lot more than her husband, and he seems to never have any calculus. Mrs. Jordan asks you why this is so. You reply:
- Mr. Jordan may brush better
- Mr. Jordan may floss better
- the fact that she has had kidney stones may make her more prone to calculus
- Mrs. Jordan needs to brush and floss better to prevent the formation of calculus
A: the fact that she has had kidney stones may make her more prone to calculus
