Dentition
Dentition (/dɛnˈtɪʃən/; from Latin dentitio, "cutting of teeth") refers to the development of teeth and their arrangement in the mouth. In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age.
Etymology
The term "dentition" is derived from the Latin word dentitio, which means "cutting of teeth". The root word dens means "tooth".
Types of Dentition
There are several types of dentition, including:
- Deciduous dentition: Also known as "baby teeth" or "milk teeth". These are the first set of teeth in the growth development of humans and other mammals. They develop during the embryonic stage of development and erupt—that is, they become visible in the mouth—during infancy.
- Permanent dentition: These are the second set of teeth that humans and some mammals develop. They are also known as "adult teeth".
- Mixed dentition: This period refers to the time during which both deciduous and permanent teeth are present in the mouth, typically occurring between the ages of six and twelve years in humans.
