This document discusses the stages of tooth development from the dental lamina stage through the bell stage. It describes the epithelial and mesenchymal tissues involved in early tooth development including the dental lamina, dental bud, inner and outer enamel epithelium, dental papilla, and stellate reticulum. The document also examines the structure of mature tooth tissues such as enamel, dentin, cementum, and pulp, and highlights features such as the dentinoenamel junction, von Ebner's lines in dentin, and cellular components of the pulp like arterioles, venules, and nerves. Pointers indicate various anatomical structures on microscope slides.
