What is VITAMIN C?● water-soluble vitamin● also known as L-ascorbic acid● sensitive to heat,light,action of oxidising
agents and metal ions● acts as a reducing agent● in human beings it is not synthesized in
body so consumed through diet
● chemical formula-C6H8O6
● 6-C lactone of alpha-keto-L-gulonic acid
FUNCTIONS OF VITAMIN C
● protective role as powerful antioxidant
● formation of collagen by acting as an electron donor in collagen hydroxylation that helps the collagen to attain a stable triple helix structure
● vitamin C reduces cancer risk by preventing the formation of N-nitroso compounds,which are potentially mutagenic
● wound healing● tissue integrity
EFFECT ON ORAL HEALTH● After 1-3 months of total vitamin C deficiency
scurvy develops.● Signs and symptoms are remembered of 4Hs- *Hemorrhage *Hyperkeratosis *Hypochondriasis *Hematologic abnormalities
● HEMORRHAGE:bleeding or abnormal blood flow;may be internal or external.
● HYPERKERATOSIS:thickening of stratum corneum with the presence of abnormal quantity of keratin.
● HYPOCHONDRIASIS:worriness about having a serious illness due to an inaccurate perception of the condition of body or mind despite the absence of actual medical condition.
● HEMATOLOGIC ABNORMALITIES:disorders primarily affecting the blood.
● In oral tissues,Scurvy is associated with- Redness of Interdental papillae Bleeding gums Dry and pale lips Ulceration Glossitis Multiple caries in teeth Tooth loosening
interdental papillae
● the enlargement and redness is due to inflammation in the lamina propria of the tissue.
● on even slight provocation gingival bleeding occurs which if left untreated may lead to severe gingivitis
gum bleeding
dry pale lips
● lips become dry and pale coloured sometimes even associated with bleeding
ulceration● painful sores inside the mouth,on the tongue,on soft
palate or inside the cheeks● round white or gray in colour with a red edge or border
glossitis
● soreness of the tongue● inflammation with depapillation
of dorsal surface ● erythematous or reddened tongue
surface with petechial submucosal hemorrhages
dental caries● decay occur due to demineralisation of enamel and dentin
tooth loosening
● due to defect in connective tissue formation tooth becomes loose and falls out early.
PEOPLE AT RISK● chronic malnourished persons who take less than 2
servings of fruits/vegetables per day-
PEOPLE AT RISK● people with other medical conditions that prevent the
intake/absorption of vitamin C- *dialysis patients *malabsorption disorders *severe dyspepsia● people who live in underdeveloped third world countries
where general malnutrition exists.
FOODS WITH ENOUGH VITAMIN C
● RICH SOURCES:Amla,Guava
● GOOD SOURCES:Drumstick leaves,Leafy vegetables,Melons,Berries,Pineapple,Tomatoes
● FAIR SOURCES:Apples,Banana,Grapes
