This course aims to help Dentistry Faculty students comprehend the histological, embryological, and functional features of the oral cavity and associated accessory organs. Starting with a general overview of the oral cavity, the course transitions to the anatomical locations and histological characteristics of the organs and their functions. It covers the relationships and histological structures of the lips, cheeks, tongue, soft palate, hard palate, teeth, tonsils, and salivary glands, as well as their embryological development.

General overview of the oral cavity; defining boundaries of the oral cavity and regional borders of the structures to be studied. Understanding the histological differences in the lips and cheeks based on anatomical location. Differentiating between the histology of the soft and hard palate. Examining the muscular and connective tissue structures of the tongue, and identifying the types and structural differences of papillae (filiform, foliate, fungiform, circumvallate). Understanding the primary lymphoid structure of the oral cavity. Understanding the microscopic histology of teeth (root, pulp, dentin, cementum, enamel, odontoblasts, ameloblasts). Describing the anatomical positions and basic histology of salivary glands (parotid, submandibular, sublingual, and minor glands), including differences based on secretion type (serous acini – mucous tubules).
