Oral Histology
Final Exam Questions
Course Introduction
Oral Histology is the study of the microscopic structure, development, and function of the tissues found in the oral cavity and associated structures. This course explores the cellular and molecular composition of oral tissues such as enamel, dentin, cementum, pulp, gingiva, and supporting bone. Students will gain an understanding of the formation, growth, and maturation of these tissues, as well as their roles in oral health and disease. The course integrates theoretical knowledge with practical laboratory experience using microscopy and staining techniques, preparing students for advanced study in dentistry and oral science.
