[Vitamin E and experimental caries in rats fed a cariogenic diet and zinc]. 1981

E Rapisarda, and A Longo

A cariogenic diet with zinc and vitamin E administered to rats for 90 days led to a reduction in caries of 21.87% by comparison with animals fed with the cariogenic diet only, and 3.12% by comparison with those that received the diet plus zinc. Although the details of the mechanism of action of vitamin E are not fully known, it is felt that its demonstrated cariostatic effect depends on its antioxidant activity and its protection of the sulphydryl groups of some enzyme system, together with its direct intervention in cell respiration. Since both vitamin E and zinc activate NAD-dependent LDH, their simultaneous administration enhances their individual cariostatic effects by bringing about a lower accumulation of lactic acid in the bacterial plaque.

UI	MeSH Term	Description	Entries
D003731	Dental Caries	Localized destruction of the tooth surface initiated by decalcification of the enamel followed by enzymatic lysis of organic structures and leading to cavity formation. If left unchecked, the cavity may penetrate the enamel and dentin and reach the pulp.

D004037	Diet, Cariogenic	A consistent pattern of food and drink consumption that contributes to the development and advancement of DENTAL CARIES.	Cariogenic Diet,Cariogenic Diets,Diets, Cariogenic
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014810	Vitamin E	A generic descriptor for all TOCOPHEROLS and TOCOTRIENOLS that exhibit ALPHA-TOCOPHEROL activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of ISOPRENOIDS.
D015032	Zinc	A metallic element of atomic number 30 and atomic weight 65.38. It is a necessary trace element in the diet, forming an essential part of many enzymes, and playing an important role in protein synthesis and in cell division. Zinc deficiency is associated with ANEMIA, short stature, HYPOGONADISM, impaired WOUND HEALING, and geophagia. It is known by the symbol Zn.
D051381	Rats	The common name for the genus Rattus.	Rattus,Rats, Laboratory,Rats, Norway,Rattus norvegicus,Laboratory Rat,Laboratory Rats,Norway Rat,Norway Rats,Rat,Rat, Laboratory,Rat, Norway,norvegicus, Rattus
