increases the risk for pneumonia and respiratory infections

Question 27

Is there an association between gum disease and rheumatoid arthritis?

Answer 27

YES

Question 28

How does malnourishment in children affect the oral cavity?

Answer 28

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

Question 29

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

Answer 29

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

Question 30

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

Answer 30

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.

Question 31

What macronutrient plays a vital role in tooth mineralization?

Answer 31

Protein

Question 32

How can cancer treatment affect nutrient intake?

Answer 32

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.
