This is one of the basic dental science courses offered by the Department of Oral Medicine and Surgery for second-year undergraduate dental students. The course aims to introduce students to the functions of the structures in the oral and maxillofacial compartment and to apply and understand the clinical significance of these functions. The lectures cover all the topics in the fields of oral and maxillofacial physiology needed by dental students during the pre-clinical stage of their training. The topics include the composition and function of human saliva, the physiology of general and special oral sensations, the physiology of mastication, swallowing, speech, and the dynamics of the masticatory system.
