Question 1

Fine abrasives are called powders or flours and are graded F, FF, and FFF for increasing fineness; these characteristics best describe which of the following abrasives?

Accepted Answer

A

Question 2

Which of the following are likely to stain the teeth during the use of the rubber cup polishing?

Accepted Answer

Black cups are likely to contain abrasive particles that can stain teeth during rubber cup polishing. Natural and synthetic rubber cups are typically made of softer materials and are less likely to cause staining.

Question 3

Various prophy brush types are used during coronal polishing such as ____________.

Accepted Answer

All of the above options are commonly used prophy brush types during coronal polishing, and the choice of which one to use will depend on the specific needs of the patient and the individual hygienist's preference. Screw-on style brushes are typically used for difficult-to-reach areas, tapered style brushes are useful for interproximal and subgingival cleaning, and flat style brushes are good for larger surface areas.

Question 4

When polishing with dental tape, you start at the oblique angle and use what type of motion?

Accepted Answer

The correct motion when using dental tape is a back and forth motion to effectively clean between the teeth.

Question 5

The rubber cup should be soft and flexible enough to adapt to the contours of the teeth.

Accepted Answer

The statement correctly describes the ideal qualities of a rubber cup used for polishing teeth. It should be soft and flexible in order to easily conform to the shape of the teeth and promote a smooth, even polish.

Question 6

The coronal polish procedure involves removing ____________.

Accepted Answer

Coronal polishing is a cosmetic dental procedure in which plaque, extrinsic stains, and soft deposits are removed from the enamel surfaces of the tooth. It does not involve the removal of intrinsic stains or calculus.

Question 7

Some contradictions or modifications for a coronal polish are:
1) if the patient is hard to control
2) the presence of orthodontic appliances
3) minor oral irritations
4) hypersensitive teeth

Accepted Answer

Coronary polish should not be performed on patients with orthodontic appliances as the polishing paste can damage the appliances. Minor oral irritations such as canker sores or cuts in the mouth can be further irritated by coronal polish. Patients with hypersensitive teeth may experience discomfort during or after the procedure. If a patient is hard to control, it is best to reconsider performing any procedure that requires cooperation. Therefore, options A and D are incorrect, while option B is too limited. Option C is the best choice as it includes all the contradictions or modifications for a coronal polish.

Question 8

After a coronal polish, a fluoride treatment is indicated.

Accepted Answer

After a coronal polish, the tooth surfaces are smooth and free of plaque or stains, which can make it easier for fluoride to penetrate and strengthen the enamel. Therefore, a fluoride treatment is usually recommended to help protect the teeth against decay.

Question 9

When dental floss is being used during a polishing procedure, the motion demonstrated is

Accepted Answer

The correct motion for using dental floss, especially during a polishing procedure, is up and down. This motion helps to effectively clean between the teeth and under the gumline without causing harm to the gums.

Question 10

Chlorhexidine stain is a permanent stain and cannot be removed with toothbrushing.

Accepted Answer

Chlorhexidine stain is not permanent and can often be removed with professional dental cleaning, though regular toothbrushing might not be effective in removing it completely.

Question 11

Which of the following stains are only exogenous in origin?

Accepted Answer

Extrinsic stains are only caused by external sources, such as food, drink, or smoking. Intrinsic stains, on the other hand, are caused by internal factors such as medication or genetics. Endogenous stains can be caused by both internal and external factors. Therefore, option B is the correct answer.

Question 12

Twelve to eighteen inches of dental tape are used as part of the tooth polishing procedure.

Accepted Answer

The question states that "Twelve to eighteen inches of dental tape are used as part of the tooth polishing procedure." This means that dental tape is used in the tooth polishing procedure, which is true.

Question 13

Examples(s) of extrinsic stains are ____________.

Accepted Answer

All three options (green stains, black-line stains, and tobacco stains) are examples of extrinsic stains, which are caused by external factors such as food, drinks, and habits like smoking.

Question 14

The rubber cup is applied to the tooth and flexed ____ mm into the sulcus.

Accepted Answer

The rubber cup is applied to the tooth and flexed 1 to 2 mm into the sulcus for effective cleaning while minimizing damage to the surrounding gum tissue.

Question 15

When the patient has a lot of stain, a more coarse abrasive is used.

Accepted Answer

A more coarse abrasive is used to effectively remove heavy stains.

Question 16

Example(s) of intrinsic stains are ____________.

Accepted Answer

Intrinsic stains occur within the tooth structure and are not removable by external cleaning methods. Nonvital tooth stains, tetracycline stains, and dental fluorosis are all examples of intrinsic stains. Therefore, the correct answer is D.

Question 17

Most commercial preparations of abrasives contain which of the following?

Accepted Answer

Most commercial preparations of abrasives contain water, a binder, and color to ensure the abrasive material is effective, cohesive, and visually appealing.

Question 18

The process of removing deposits and polishing the teeth is a ____________.

Accepted Answer

Prophylaxis is the procedure of removing deposits and polishing the teeth, typically done during a routine dental cleaning. Root planing is a deeper cleaning procedure for removing calculus and plaque from below the gum line. Gingival curettage is a surgical procedure for removing diseased gum tissue. Therefore, A is the correct answer.

Question 19

The coronal polish is the polishing of the ____________.

Accepted Answer

The coronal polish refers specifically to the polishing of the clinical crown, which is the part of the tooth that is visible above the gum line.

Question 20

When polishing, to prevent any enamel from being removed during the procedure, ____________.

Accepted Answer

Small amounts of enamel are always removed during a polish, regardless of the precautions taken. This is an inherent part of the polishing process, as it involves the removal of surface stains and plaque, which inevitably leads to the removal of a minimal amount of enamel.
