His Tooth is Funny Looking. What is It?
Discussion
Teeth are specialized anatomic parts of the human body that are developed between the ectoderm and ecomesenchyme in a complex process called odontogenesis. More than 300 genes have been identified that influence odontogenesis. Dental abnormalities can have significance for cosmesis, malocclusion, dental caries and periodontal diseases. It is not uncommon for more than 1 area to be affected. For example, Hutchinson teeth which are caused by congenital syphilis are smaller with wider spacing between the teeth within the arch, and also have a characteristic notching.
