2. Acute caries. Deciduous dental hard tissue is thin and low degree of calcification, poor acid, oral cariogenic factors, extremely susceptible to dental caries and caries on the dental hard tissue has developed rapidly, can easily lead to infection of the pulp nerve. Some children in a short period of time in the mouth a great many teeth are caries, into a black root, medically dental instruments known as "rampant caries", common in the frail, eating sweets and children with poor oral hygiene.
