This document provides an overview of dental anatomy, including the parts of teeth and their surfaces. It discusses the maxillary and mandibular arches, dental quadrants, and tooth tissues like enamel, dentin, cementum and pulp. The types of teeth are described as primary/deciduous or permanent. Anterior teeth are distinguished from posterior teeth. The surfaces of teeth, including labial, buccal, facial, lingual, palatal, incisal, occlusal, distal and mesial are defined in terms of their location and orientation. Thirds divisions of the crown and root are also explained.
