Introduction

Dental anatomy: is the study of the development, morphology, function, and identity of each tooth in the human dentitions, as well as the way in which the teeth relate in shape, form, structure, colour, and function to the other teeth in the same dental arch and in the opposing arch.
Thus, the study of dental anatomy, physiology, and occlusion provides one of the basic components of the skills needed to practice all phases of dentistry.

Man is a hetrodent, which means that he has different-shaped teeth.
Man is a diphyodent, which means that he has two sets of teeth; primary teeth (deciduous teeth or milk teeth or baby teeth) and permanent teeth (succedaneous teeth).
Teeth are grouped into:
1. Anterior teeth: which include the incisors and the canines.
2. Posterior teeth: which include the premolars and molars.
The jaw is the bone which caries the teeth. There are two jaws:
1.The upper jaw: which is fixed , and is called “The maxilla”.
2.The lower jaw: which is movable, and is called ”The mandible”.
