oral health and mineral

  1. 1. By Dentist janvier habumugisha 1
  2. 2. 2  Minerals play important role in our life especially in bone and tooth formation  Calcium which is more abundant at 99% in bone and teeth  Phosphorus occupy 80-90% in bone and tooth and magnesium 60% in bone and teeth, other mineral such as fluoride, zinc,copper,iron are also available in bone and teeth as well as in other tissues  And they have different sources
  3. 3.  Important minerals that provide benefits to your oral health are: 1.Calcium—Your teeth and jaw are mostly made out of calcium so consuming calcium on a regular basis helps keep your teeth enamel and jaw strong and healthy.  Sources of Calcium: Milk, yogurt, cheese, beans and kale
  4. 4. 2.Iron—Consuming too little of iron can cause tongue inflammation or mouth sores. The main role of iron is to transport oxygen throughout your body so a lack of iron can also contribute to infections and bacteria build up in the mouth due to lack of oxygen flow in your body.  Sources of Iron: Liver and red meat
  5. 5. 3.Zinc—Zinc helps to prevent the growth of bacteria and the build-up of plaque along your gum line.  Sources of Zinc: Wheat, cereal, wild rice, cheese, and beef 4.Magnesium—Magnesium helps to build strong enamel for your teeth and helps prevent the formation of cavities.  Sources of Magnesium: Spinach, kale, dark chocolate
  6. 6. MINERAL ROLE SOURCE Calcium Needed for tooth Milk, cheese, yogurt, Phosphorous Magnesium development, prevents loss of jaw bone and teeth, rebuilds hard surface of the teeth (enamel) seafood, dark green leafy vegetables Fluoride Prevents tooth decay, helps repair enamel Fluoridated water, black tea, sardines Zinc Needed for digestion, healing cold and canker sores Liver, various meats, eggs, seafood, whole-grain cereals Iodine Needed for tooth development Iodized salt, seafood, kelp, saltwater fish Copper Absorbs iron. Helps produce blood and nerve fibers Liver, kidney, seafood, nuts, seeds, tap water Iron Protects against oral cancer and helps the immune system Liver, eggs, fish, seafood, various other meats, enriched breads & cereals, green leafy vegetables Potassium Needed for nerve function and muscle contractions Vegetables, legumes, fruits, milk, cheese, various meats, whole grains
  7. 7. Mineral deficiencies 7  iron.,zinc and copper play the following roles:  Aid in collagen formation  Wound healing  Regulate inflammation  Iron deficiency can lead to anemia, decreased immunity, angular chelitis, glossitis ,pallor of lip and mucosa  Zinc deficiency cause loss of taste and smell,xerostomia,candidiasis,Periodontal diseases,caries
  8. 8. 8  Calcium deficiency lead to osteopenia, osteoporosis, succeptibility to dental caries,increased tooth mobility, convulsion  Phosphorus w/c favour vit D absorption and bone &teeth formation,acid base balance  Phosphorus deficiency cause bone demineralization, calcium loss,succeptibility to caries  Copper deficiencies may lead to:osteoporosis, arthritits, lesion with connective tissues
  9. 9. Fluoride 9  Fluoride is the ionic form of the element fluorine.  Fluoride is a mineral found throughout the earth's crust and widely distributed in nature.  Found in soils rich in fluorspar,cryolite,and other minerals.
  10. 10. Sources 10 Small amounts:fruits,vegetables,cereals. Rich amounts:sea foods and tea leaves.
  11. 11. Chief Source of Flouride. 11  Water  Topical agents (toothpaste). According to WHO  Flouridated Salt / Milk
  12. 12. Distribution of Flourides. 12  Teeth and skeleton have the highest concentrations of fluoride. --Due to the affinity of fluoride to calcium.  Fluoride content of teeth increases rapidly during early mineralization periods and continues to increase with age,but at as lower rate.
  13. 13. Prevention of cavities by Flouride. Two different ways:  Fluoride concentrates in the growing bones and developing teeth of children, helping to harden the enamel on baby and adult teeth before they emerge.  Fluoride helps to harden the enamel on adult teeth that have already emerged.  APPLICATIONS  Topically (On the surface).  Systematically (Throughout the body). 13
  14. 14. Topical Flouride Sources. 14  Toothpaste.  Mouthrinses.  Professionally applied gels, foams, rinses.  Our own saliva.
  15. 15. Topical Applications. 15 Helps to Prevent.  Cavities by strengthening the surface of the teeth (the enamel).  Reducing the ability of bacteria contained in dental plaque to produce acid.  Re-mineralizing existing dental cavities. Fluoride can actually heal small cavities in some cases, and prevent the need for dental fillings.
  16. 16. Systemically Flouride Sources. 16  Water and other beverages.  Foods  Drops  Tablets  Etc.
  17. 17. Application of Systemically Flouride.17  Strengthening of developing teeth from infancy to adolescence.  Strengthens teeth by the formation of harder enamel by converting HYDROXYAPATITE CRYSTALS to FLUORAPATITE.  Flourapatite is less vulnerable to damage from plaque acids
  18. 18. Dental fluorosis?  Dental fluorosis is a developmental disturbance of dental enamel caused by excessive exposure to high concentrations of fluoride during tooth development.  Due to Inappropriate use of fluoride-containing dental products. 18
  19. 19. Types of Dental Flourosis.  Mild Dental Flourosis (common).  Sever Dental Flourosis. 19
  20. 20. Mild Dental Flourosis  Unnoticeable, tiny white streaks or specks in the enamel of the tooth. 20
  21. 21. Sever Dental Flourosis. 21  Tooth appearance is marred by discoloration or brown markings.  Pitted Enamel, Rough and Hard to Clean. The spots and stains left by fluorosis are permanent and may darken over time.
  22. 22. Severe Dental Flourosis. (Case 1) 22
  23. 23. Severe Dental Flourosis. (Case 2) 23
  24. 24. Water Fluoridation. 24  Addition of Flouride to Public water Supply.  Community water fluoridation is safe and effective in preventing dental caries in both children and adults.  Water fluoridation benefits all residents served by community water supplies regardless of their social or economic status. Fluoridation does not affect the appearance, taste or smell of drinking water.
  25. 25. REFERENCE  - See more at: http://oralhealth.deltadental.com/22,HD8#sthash.YllvRdD8.dpuf  Bohn T, et al. Phytic acid added to white-wheat bread inhibits fractional apparent magnesium absorption in humans. American Journal of Clinical Nutrition. 2004 79:418 –23.
