[Cariogenicity and cariostatic properties of different types of milk-review].

The purpose of this study is to introduce some information about local and systemic effects of different kinds of milk in oral health, through the explicitness of its cariogenicity and cariostatic properties. Different kinds of milk and milk products are consumed most commonly by the worldwide population, raising the interest of researchers in its influence in the oral health for some decades. Several studies have been conducted to associate the consumption of bovine-, human- and infant formula-milk with caries development and other dental defect, but controversial results have not been able to define the cariogenic and cariostatic potential of different kinds of milk. Bovine milk has some cariostatic components as casein, lipids and antibacterial enzyme, though it has 4% lactose, supposedly cariogenic sugar. Human milk has been related to a sort of caries which is like bottle caries, even though some studies have demonstrated its non cariogenicity. The infant formula milk, which is elaborated for specific period in the childhood, has received low control on its potential for developing caries. It could be of great value to elucidate the controversy surrounding the cariogenicity and cariostatic properties of different kinds of milk, concerning caries prevention during infant and adult life.
