Oral Medicine and Radiology

About us

Oral Medicine is a branch of dental science which is at the interface between Medicine and Dentistry. Diagnosis of oral soft and hard tissue lesions, dental management of medically compromised patients, non-invasive management of mucosal lesions, chronic orofacial pain, temporomandibular disorders and salivary gland diseases is emphasized here thus contributing to a comprehensive patient care.

Oral Radiology deals with the techniques and interpretation of radiographs of the maxillofacial region for diagnosis and treatment planning.

The Department of Oral Medicine and Radiology of Coorg Institute of Dental Sciences is the place where the initial screening of all outpatients attending the hospital is performed and clinical and radiographic diagnosis of various diseases of the oral and paraoral structures is established. This department attends to an average of over 250 patients daily. Here, the undergraduate and post graduate students work under close supervision of faculty. The Department is involved in various research activities including clinical trials and collaborative research with universities abroad.

Our Vision
is to train students in the field of Oral Medicine and Radiology so as to ensure a high level of competence in both general and special area of interest in the specialty and prepare him/her for a career in specialty practice, research and didactic skills with primary emphasis on patient management skills and high ethical standards.
