What is congenital tooth agenesis

What is congenital tooth agenesis...

Congenital tooth agenesis refers to the condition in which one or more teeth are missing at birth, regardless of the type of tooth.
Congenital tooth agenesis can appear as a symptom of congenital anomaly syndromes or as a non-syndromic condition (not caused by disease), It is thought to result from various illnesses depending on the number of missing teeth, the types of teeth (deciduous/permanent, incisors/canines/premolars, etc.), the location of tooth eruption in the upper or lower jaw, left or right side, and differences in the causative genes.
Among them, if six or more teeth are missing, it is considered to be largely related to genetics, with a probability said to be 0.1% of the entire population.

"Congenital Tooth Agenesis " and "Genetic Research"

Genes are like blueprints in our cells that make up the body.
Just as everyone has different faces, genes also differ slightly from person to person.
Research on this congenital tooth agenesis is largely related to genetic factors. By using animals to investigate how these factors work, examining the genes of both healthy individuals and those with fewer teeth, and identifying genes that may determine the number of teeth, we hope to develop medicine that can help teeth grow. This kind of research is called "genetic research."
