Histology is the science and study of tissues. Histo means a tissue, while Logy means science. By studying oral histology and embryology, you will gain a strong foundation in oral biology. The topic you study will focus on the development and structure of cells and tissues, the stages of tooth development and maturation. Different parts of a tissue, like cells, intercellular substance, tissue fluids, and the different parts of a human tooth, like enamel, dentin, dental pulp.
