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. Academic Task provides Oral Histology MCQs with answers. All these teeth histology MCQs are chosen from trusted and best reference books on oral histology. These histology MCQs are also helpful for the preparation of interviews, entrance examinations, other competitive examinations, and certifications for all Experienced, Freshers and Students. Also, check MCQs on Oral Pathology here.
