Human teeth , we all are aware that it grow only twice a life .
First - baby teeth which is also called deciduous teeth they roughly erupt from 6-3 years .
Second- permanent teeth they erupt at the age of 6-7 yrs to 12-13 yrs .
But what if the person does not grow the teeth .
There developmental dental anomalies.
HYPODONTIA - a person misses one to six teeth .
OLIGODONTIA - absence of 6 or more permanent teeth.
ANODONTIA - a genetic disorder , complete absence of teeth .
They come under the congenital cases which are related to genetic factors.
There are acquired factors means person who lost tooth due the environmental factors like teeth lost due to decay ,accidents or other factor.
In our body there is a protein called USAG-1 which regulates the tooth development which inhibits tooth growth .
JAPAN have developed an “anti-USAG-1 antibody “ that suppressed the function of USAG-1 .
By administering this antibody , new teeth can grow without stopping the growth of tooth embryo.
