4. The word "vitamin" comes from the Latin word “vita”, means
"life”.
Everybody must eat a certain amount of vitamins to stay healthy.
Vitamins are chemicals found in very small amounts in many
different foods.
5. vitamins may be regarded as organic compounds required
in the diet in small amounts to perform specific biological
functions for normal maintenance of optimum growth and
health of the organism.
6. Frederick G. Hopkins, reported in
1906 that there was an unknown and
essential nutrients present in natural
foods.
Casimir Funk obtained an anti-
beriberi substance from rice polishing.
He called that substances ‘vital
amines’.
Later its become ‘VITAMINS’
7. Vitamins are required in small quantities in the diet

Low levels of ascorbic acid influence the metabolism of
collagen within the periodontium ( Waerhaug J, 1958)
Leading to loss of periodontal bone. ( Glickman I,1948 )
Increases the permeability of the oral mucosa to tritiated
endotoxin and tritiated inulin and of normal human crevicular

It is also used as anti-stress factor.
57. Vitamin B6 is part of the vitamin B complex
group, and its active form, Pyridoxal 5'-

65. • Folic acid or folacin (folium-leaf) is abundantly found
in green leafy vegetables.
• It is required for synthesis of certain aminoacids, purins
and pyrimidine- thymine
67. Helps in formation of RBC

developing fetus
Folic acid improves the lactation.
DNA synthesis-transfer of single carbon units and synthesis of
adenine and guanine
Homocysteine metabolism
Neurotransmitter formation
68. Macrocytic anemia
Folic acid deficiency in pregnant women may cause
neural defects in the fetus.
69. Folic acid–deficient animals demonstrate necrosis of the
gingiva, periodontal ligament, and alveolar bone
The absence of inflammation is the result of deficiency-
induced granulocytopenia.
In humans with sprue and other folic acid deficiency states,
generalized stomatitis occurs, which may be accompanied by
ulcerated glossitis and cheilitis.
Vogel et al. (1978) reported a significant reduction of gingival
inflammation after systemic or local use of folic acid
compared with placebo. This reduction occurred with no
change in plaque accumulation.
70. Vitamin B12 is complex organomatrix compound
called as cobalamin which is cobalt containing
porphyrin. It is freely soluble in water.

and lactation :4 mcg
per day
DAILY REQUIRMENT
72. Essential for production of RBCs.
It improves concentration, memory, & balance.
It is important for metabolism of fat, carbohydrate ,
proteins, folic acid.
It promotes growth and increases apatite.
73. Perinicious anemia
The excretion of methylmalonic acid in urine and estimation of
serum B12levelare used to assess B12 deficiency.
Common oral effects of vitamin b deficiency are burning
sensations in the mouth and on the tongue, trouble swallowing,
swollen tongue, and pale tissues in the inner cheeks that could
break apart easily and come off
74. •Vitamins do not yield energy but enable the body to use other nutrients.
•Since the body is generally unable to synthesize them (at least in
sufficient amounts) they must be provided by food.
•A well balanced diet supplies in most instances the vitamin needs of a
healthy person.
•The minimum intake for the maintenance of health in respect of many
of the vitamins thus appears to be important.
•Vitamin C and Folic acid plays a major role in many of the important
functions of the oral cavity so it is necessary to take proper amount of
vitamin c to maintain proper function of the body.
