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
![Page 9: Impact of Vitamin C on Oral Health](https://reader031.vdocuments.us/reader031/viewer/2022032616/55a745cc1a28ab4b518b4681/html5/thumbnails/9.jpg)
● 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
![Page 15: Impact of Vitamin C on Oral Health](https://reader031.vdocuments.us/reader031/viewer/2022032616/55a745cc1a28ab4b518b4681/html5/thumbnails/15.jpg)
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
![Page 17: Impact of Vitamin C on Oral Health](https://reader031.vdocuments.us/reader031/viewer/2022032616/55a745cc1a28ab4b518b4681/html5/thumbnails/17.jpg)
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.
