Dental Anatomy

Topics
Jaws

This segment provides an overview of the bones forming the upper and lower jaw, including their anatomical landmarks. Learn about the temporomandibular joint, which provides movements of the lower jaw. This article also includes an overview on the muscles of mastication.

Deciduous teeth

In this study unit, learn about incisors, canines, first and second maxillary and mandibular molar teeth of the primary dentition known collectively as the primary or decidious teeth. This article includes information about the differences between primary and secondary dentition, and about the timing when the primary dentition typically appears.
