A study of basic structure form and functions of the teeth and their related parts. It is the study of the intrinsic and environmental structures of the oral cavity and its blood and nerve supply. The lab portion will provide knowledge of eruption dates individual descriptions and external features of the teeth. Experience will be provided in identifying teeth.
