Nutrition and Periodontal Disease Flashcards
Why is nutrition important?
- Nutrition moderates the immune response
- The rapid turnover of the PDL is dependent on vitamin A,C iron, folic acid
- Nutrigenomics
Give some nutrients that are needed for rapid turnover of the PDL to occur
- Vitamin a
- Vitamin C
- Protein
- Folic acid
- Iron
What Is Nutrigenomics?
Nutriton modifying gene expression
Study of the genetic basis for variable responses to diet
Give examples of major nutrients
Protein
Carbohydrates
Lipids
Give examples of minor nutrients
Vitamins
Minerals
What are vitamins?
Organic substances present in small quantities in food
Why are vitamins important?
They are requires to maintain metabolic reactions
Give examples of fat soluble vitamins
Vitamins A, D, E and K
Give examples of water soluble vitamins
Vitamins C,B
Why is vitamin A important?
It is essential for:
- Night vision
- Maturation of epithelial tissues
What can excess vitamin A lead to
Can cause:
- Gingival erosions
- Bleeding
- Loss of keratinisation
- Headache
- Dry mouth
- Loss of hair
Why is vitamin D important?
Essential in minting blood calcium levels and metabolism of osseous tissues
Where do we get vitamin D from?
Sunlight
Give some dietary sources of vitamin D
- Oily fish
- Cod liver oil
- Egg yolk
- Meat
- Milk
- margarine,
- some breakfast cereals and yoghurts
What can the active metabolite of Active metabolite of 25-hydroxyvitamin D, 1,25 dihydroxyvitamin D, inhibit?
Can inhibit cytokine production and cell proliferation
What is a lack of vitamin D associated with
periodontal diseases
What is vitamin C made by?
All plants and most animals
Can humans make vitamin C?
NO
Why is vitamin C important ?
It is required for collagen maturation (Hydroxylation of lysine and proline)
What can vitaminC deficiency lead to?
Scurvy
What can vitamin C deficient lead to ?
Muscle weakness, swollen, painful joints, tissue bleeding Marked gingivitis
How can a low vitamin C diet affect your oral cavity
can increase gingival inflammation and bleeding but not attachment loss
What is the recommended amount of vitaminC we would have?
500mg 3X daily for 4 weeks
Which habit can decrease your vitamin C levels?
Smoking
Why is vitamin B important?
- To get energy from carbohydrates and fats
- Important in red cell formation
- In proteins and amino acid metabolism
What has one study said vitamin B does?
It can improve periodontal wound healing
Why is calcium important?
It is required for Normal bone metabolism
What is calcium homeostasis controlled by?
Controlled by parathyroid hormone and calcitonin
What has a low calcium diet been linked with?
Low dietary calcium links with severe periodontal disease
What is the link between dairy products and periodontitis?
Low dietary calcium results in more severe periodontal disease
What has magnesium deficiency been associated with
Increased periodontal disease
How does fibre link with periodontitis?
Increased fibre in diet is associated with less perio disease
Why might increased fibre reduce the risk of periodontitis disease?
May be due to less dental plaque accumulation
May have nutritional benefits on periodontal tissues
How does alcohol affect periodontal disease?
Alcohol consumption may b associated with increased severity of clinical attachment loss in a dose dependent fashion
How do vegetables affect periodontal disease?
Increased intake of vegetables negatively correlates with periodontal disease
Define obesity
defined sa sienne having a body mass index of greater than 30kg.m^2
How many people in the UK are being classified as obese
29% adults
20% 11 year olds
What is obesity a risk factor for?
1. Hypertension 2 Type 2 diabetes 3. Cornoary heat disease 4. Stroke 5. gallbladder disease, 6. osteoarthritis 7. sleep apnea 8. respiratory problems 9. some types of cancer
Give some oral coansitons that are affected by obesity
- Xerostomia
- Caries
- Periodontisis
Give examples of fat substances that may modulate periodontitis and how hey do this
Adipose tissues and adipose macrophages are a source of inflammatory cytokines called adipokines or adipocytokines, which may modulate periodontitis.
Why does increasing body fat increase likelihood of periodontitis ?
As Adipose tissues and adipose macrophages are a source of inflammatory cytokines called adipokines or adipocytokines, which may modulate periodontitis.
How much more likely are you to have periodontal disease if you are obese?
8.6 times more likely
Aside from BMI what else is important to consider in obesities patients?
Their total body fat
Their waste circumference
The location where fat is accumulating
In relation to diet and exercise what advice would you give o patients to help reduce their risk of developing periodontal disease
- Lower calorie intake is associated with decreased periodontal disease
- Weight loss and exercise has shown periodontal benefits
- Increased physical activity is associated with lower periodontal disease
What are the benefits of fish oils?
Fish oils have anti inflammatory actions which could benefit periodontal health
