An Overview

The Division of Oral Medicine came into existence as a division of the Department of Oral Medicine and Periodontology in 1985 at the time the Faculty of Dental Sciences was established. The Division moved to spacious facilities when the new Faculty of Dental Sciences buildings were commissioned in June 1998. The Division consists of the Oral Medicine clinic and the Oral Medicine Laboratory. The Division is closely linked to the Division of Radiology and students' clerkship in oral medicine includes learning of radiology. The Division of Radiology now functions as a semi-independent division. The principal functions of the division are undergraduate and postgraduate teaching of oral medicine, diagnosis and treatment of orofacial medical conditions and research.
