A new study has shown that baby teeth are a rich source of stem cells,which are like protocells and can be grown into multiple kinds of cells id needed. That means that if later in life a child needs replacement of tissues for whatever reasons ,the stem cells froeeth andm their baby teeth can be used to trow the needed tissue. Research shows that stem cells can be harvested from baby teeth and have potential dental and medical uses in repairing and regenerating tissues, they are not yet sure to what degree or when potential uses will come to pass. Dental stem cells have the potential to secure your child from ailments such as a stroke, corneal injury, spinal cord inuury, arthritis, juvenile diabetes, etc.. The younger the person, the more vital are the stem cells. To utilize the full potential of your child’s stem cells preserve them now. Various companies have come forward for stem cell banking.

Dental caries is a bacterial infection that causes progressive demineralisation and destruction of the calcified structures of the teeth leading to cavitations. It is a multifactorial disease. Dental caries involves the formation of a biofilm around the tooth structure. Biofilm consists of cariogenic bacteria and the substrate upon which it acts. Cariogenic bacteria release acids during the process of fermentation of the substrate and these in turn cause demineralisation There are numerous intraoral microbes that play a key role in the development of dental caries or tooth decay. Streptococcus mutans are the most important group of cariogenic bacteria. The other bacteria playing key roles in caries development are Streptococcus sobrinusand Lactobacillus . The worldwide prevalence of dental caries is very high. The incidence of dental caries can be prevented to a certain extend by good oral hygiene habits, dietary modifications and fluoride application. Recent advances in immunology have raised a possibility for an effective vaccine against dental caries. Active immunisation, Passive immunisation and DNA vaccines for the prophylaxis of dental caries are under research. Active immunisation for dental caries utilizes the protective effect of salivary IgA antibodies to S.mutans or S.sobrinus. The S.mutans components that are involved in adhesion, glucan formation or binding, or in cell wall synthesis are targeted by the vaccine. Passive immunisation may be achieved by administration of pre-formed immune-reactive serum or antibodies. Murine monoclonal antibodies, egg-yolk and bovine milk immunoglobulins generated against S.mutans has been used to control the dental caries in humans. Research studies have shown that DNA vaccines are capable of inducing the synthesis of IgA antibodies against S.mutans which would further prevent the adhesion of the bacteria to the tooth surface.
