Dental arch development in a set of triplets
1Dental School, King's College School of Medicine and Dentistry, London, England.
Abstract:
A set of male triplets, of whom the two youngest appear to be identical, has been followed and recorded on plaster casts from 1 month to young adulthood. Measurements of tooth size, arch breadth, length, and circumference, as well as arch relationship, were made at five stages of development. There was a general tendency for the identical pair to become more similar after puberty, and less like their dizygotic brother. Attention is drawn to the potential value of a longitudinal study on a sample of sets of similar sex triplets each containing two identical individuals.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
