1_The role of diet and nutrition in the etiology and prevention of oral diseases.
  1. PERIODENTAL DISEASE
    1. progress more in Undernourished population
      1. increased production of reactive oxygen
        1. ascorbic acid, beta carotenes and alpha tocoferol
          1. protective role of antioxidants
            1. fruits, vegetables, grains and seeds.
      2. DISEASES OF THE ORAL MUCOSA
        1. diet is a preventable risk factor for oral cancer.
          1. hot foods and drinks, more risk for cancer
            1. decreases with vegetables and fruits
            2. HIV/AIDS
              1. Poor nutritional status
                1. more rapidly development of oral symptoms.
                  1. ulceration, candidiasis,drug induced xerostomia and neoplasms.
              2. DEVELOPMENTAL DEFECTS ON THE ENAMEL
                1. Nutritional status affects the teeth pre-eruptively.
                  1. deficiency of vtamin A and D
                    1. Enamel hypopllasia
                      1. increased suceptibilty to dental caries.
                      2. salivary gland atrophy
                  2. DENTAL EROSION
                    1. irreversible loss of dental hard tissue
                      1. associated with acidic foods and drinks
                        1. fruit juices, soft drinks, vinegar, citrus fruits and berries
                      2. age- related
                      3. DENTAL CARIES
                        1. had increased because of dietary sugars.
                          1. deamination of enamel and dentine
                            1. diet high in sugars increased caries.
                              1. dietary factors
                                1. cow´s milk, wholegrain foods, peanuts, hard cheeses, and chewing gum
                                  1. breastfeeding associated with low levels of caries
                                2. FREQUENCY, AMOUNT AND TYPE OF SUGARS
                                  1. free sugars
                                    1. mono and polisaccharides added to food by manufacturer
                                      1. excludes sugar present in whole fruits, vegetables and milk.
                                        1. little or no threat to dental care
                                      2. INFLUENCE OF FLUORIDE
                                        1. Protects against dental caries
                                          1. reduce children caries by up to a 50%
                                            1. fluoride with a reduction of sugars
                                              1. caries reduction
                                            2. SAFE LEVELS OF FREE SUGARS
                                              1. if the consumption of sugar exceeds 15 kg/personj/year
                                                1. caries increased and intensifies
                                                2. free suigar intake less than 10% of total diet
                                                  1. four times or less per day
                                                  2. STARCH- RICH STAPLE FOODS, FRUITS AND DENTAL CARIES.
                                                    1. high starch/low sugars diet
                                                      1. low levels of caries
                                                      2. starch-containing foods reduce plaque PH.
                                                        1. fruits are not significant in the development of dental caries.
