Q

What is the definition of ORAL HEALTH?

A

improving quality of life through oral hygiene and healthy eating, which can reduce the risks of oral disease. There is a bidirectional relationship between diet and oral health. A healthy/ balanced diet is associated with good periodontal health and teeth, as well as good quality of saliva

Q

What are micronutrients?

A

water, vitamins (organic molecules), and minerals (inorganic molecules). They dont yield energy but support metabolic processes.

A

amount of nutrients per kcal

17

  1. adequacy : eating enough energy, nutrients, and fiber
  2. Balance:
  3. Kcal control
  4. nutrient density
  5. moderation
  6. variety
18
Q

What age group is canadas food guide intended for?

A

2 years and older

19
Q

What is a nutrient content claim in food labels?

A

characterizes the quantity of a nutrient in a food using words (not numbers), such as “low,zero, high”

20
Q

What are health claims in food labels?

A

describe a relationship between a nutrient/food and a disease or health related condition

21
Q

What are structure and function claims on food labels?

A

describes how a food/nutrient may affect a structure and/or function of the body.

22
Q

What are the 2 main roles for diet in oral health?

A
  1. food and its nutrients contribute to oral health

2. eating habits

23
Q

How does someone with poor teeth or lack of teeth altogether affect diet? Explain the cycle

A

Someone with eating impairment will affect food choices, often eating poor foods, which in turn causes malnutrition and leads to problems in teeth or oral soft tissues

24
Q

What is the proportion of the population that have gum disease?

A

80%

25
Q

What affect does gum disease have on the heart?

A

people with gum disease are 2x as likely to die from heart attack and 3x as likely to die from a stroke

26
Q

What effect does poor oral hygiene have on respiratory problems?

A

increases the risk for pneumonia and respiratory infections

27
Q

Is there an association between gum disease and rheumatoid arthritis?

A

YES

28
Q

How does malnourishment in children affect the oral cavity?

A

abnormal tooth development, delayed tooth eruption, compromised tooth structure, dental caries. also affects salivary flow and composition.

29
Q

What vitamins(organic) and minerals(inorganic) affect tooth development and maintenance?

A

vitamins A,C,D and minerals calcium, phosphorous, and fluoride

30
Q

Why is malnourishment so critical to avoid during child development? Cant the child just eat healthy later on?

A

Because there is little change to teeth once they are formed. No because there will be little change to the teeth after they have formed.

31
Q

What macronutrient plays a vital role in tooth mineralization?

A

Protein

32
Q

How can cancer treatment affect nutrient intake?

A

Chemo, radiation, and surgery can cause painful stomatitis (inflammation of oral tissues), and xerostomia, and fibrosis of chewing muscles, taste change, and tooth loss. This will most likely impair nutrient intake and damper the bodys ability to fight disease and heal.

33
Q

What are 3 eating disorders?

A
  1. anorexia nervosa
  2. bulimia nervosa
  3. binge eating
34
Q

What are 3 oral signs of eating disorders?

A
  1. erosive teeth wear
  2. low unstimulated salivary flow
  3. moderate - severe dental caries
35
Q

How can diabetes affect oral health?

A

diabetes is a chronic metabolic disease with oral health implications.

Can lead to dental caries, peri disease, decreased salivary flow/dry mouth, and risk of tooth loss (perio related)
