Deck 26: Nutrition for Oral and Dental Health

Question 1

Along with tooth susceptibility, bacterial presence in the plaque, and sufficient exposure to promote acid production, what other factor is necessary for the development of dental caries?

A)An anaerobic environment
B)An available substrate for bacterial metabolism
C)Adequate saliva
D)Alkaline pH

Answer 1

B
Oral bacteria require fermentable carbohydrate as a substrate for the production of the acids that contribute to tooth decay.Because the oral and nasal cavities expose these bacteria to oxygen, the bacteria do not function anaerobically.Adequate saliva production and alkaline pH reduce the likelihood of dental caries.

Question 2

Which of the following is a significant food source of fluoride?

A)Brewed tea
B)Beef
C)Coffee
D)Spinach

Answer 2

A
Most foods, unless prepared with fluoridated water, contain minimal amounts of fluoride, except for brewed tea.

Question 3

What is the appropriate dietary management for a patient with Sjögren's syndrome?

A)Provide foods that are pureed in form.
B)Provide oral liquid supplements.
C)Provide moist, soft, nonspicy food.
D)Begin fluid restriction.

Answer 3

C
Sjögren's syndrome results in salivary gland dysfunction, which could cause xerostomia.Providing moist, soft, nonspicy foods and increasing fluid consumption make it easier for the patient to eat without experiencing pain.Pureed foods are more commonly used in situations in which the patient has either chewing or swallowing difficulties.Oral liquid supplements may be necessary when oral intake is severely impaired, such as when stomatitis or ulceration of the mouth occurs.

Question 4

Why are foods that require a lot of chewing effective in promoting good dental health?

A)They cleanse the tooth surface.
B)They promote saliva flow.
C)They lower the acidity level of the mouth.
D)They decrease the fermentation of carbohydrate.

Question 5

Cheese is considered to be anticariogenic because it

A)induces an alkaline saliva.
B)induces an acidic saliva.
C)induces a neutral saliva.
D)decreases saliva production.

Question 6

Which can reduce the cariogenicity of a meal when it follows the meal?

A)Eating dessert
B)Eating a snack of pretzels
C)Chewing sugar-free gum
D)Eating fruit

Question 7

Which of the following may result from oral candidiasis?

A)Tooth loss
B)Dry mouth
C)Ulcer formation
D)Odynophagia

Question 8

To limit the chances of developing early childhood caries, which of the following should never be provided in a bottle?

A)Formula
B)Milk
C)Juice
D)All of the above

Question 9

Under which conditions should an infant receive fluoride supplementation?

A)At 6 months if breastfed in a fluoridated community
B)At 6 months if breastfed and given water in a fluoridated community
C)At 3 months if breastfed in a fluoridated community
D)At 3 months if breastfed and given water in a fluoridated community

Question 10

Which of these is NOT a recommendation for people with xerostomia?

A)Drink water with lemon.
B)Chew xylitol-containing gum.
C)Add peanut butter when eating crackers.
D)Eat moist foods.

Question 11

Which of the following are characteristics of foods having a low cariogenic potential?

A)High content of protein, calcium, and phosphorus
B)Low content of protein, calcium, and phosphorus
C)Low content of phosphorus and protein
D)High content of magnesium and fat

Question 12

What role do nuts play in regard to the development of dental caries?

A)They are cariogenic.
B)They are cariostatic.
C)They are anticariogenic.
D)They are cariogenic when eaten with fruit.

Question 13

Which of the following foods would be identified to a patient as being potentially cariogenic?

A)Raw carrots and apples
B)Cheddar cheese
C)Butter
D)Crackers and pretzels

Question 14

The ingestion of which of the following is most likely to promote bacterial activity that promotes dental caries?

A)Sucrose, glucose, and fructose
B)Xylitol, mannitol, and lactose
C)Aspartame, saccharin, and cyclamate
D)Xylitol, saccharin, and galactose

Question 15

The caries process begins when the pH drops below what level?

A)7
B)6.5
C)5.5
D)5

Question 16

The optimal level of water fluoridation to protect against dental caries is _____ ppm.

A)0.1 to 0.6
B)0.7 to 1.2
C)1.2 to 1.4
D)1.4 to 2.0

Question 17

Maternal deficiency of vitamin A could result in what effect in relation to fetal or infant tooth development?

A)Decreased tooth size
B)Salivary gland dysfunction
C)Decreased mineral content
D)Mottled enamel

Question 18

Which of the following can commonly occur after a patient develops gingival recession?

A)Root caries
B)Lingual caries
C)Increased salivation
D)Increased enamel production

When and for how long does tooth mineralization occur?

A)From 2 months' gestation through 5 years of age
B)From 4 months' gestation through the preteen years
C)From 2 months' gestation through the preteen years
D)From 4 months' gestation through 5 years of age

Question 20

When a patient is identified as wearing full dentures, what else should be included in the nutrition assessment of the patient?

A)Recent changes in the patient's weight
B)The patient's regular daily fluid intake
C)When the patient last had her own teeth
D)The patient's daily intake of cariogenic foods
