The Department of Oral Pathology and Microbiology is that branch of Dentistry which is concerned with the scientific study of the causes and effects of oral diseases, an understanding of which is essential for diagnosis, development of rational treatment protocols and preventive programs. Here, we focus on nature, identification and management of diseases affecting the oral and maxillofacial region as well as associated structures.

This department imparts teaching and training to the students in the subjects of Dental Anatomy including Oral Histology, Human Embryology and Oral& Maxillofacial Pathology & Microbiology in 1st and 3rd year of BDS course of studies respectively. The curriculum is related to the holistic development of the students in the above mentioned subjects.

We deal with the diagnosis of pathological specimens like ulcers, lumps, red and white lesions of the oral cavity which are surgically removed from patients. The samples are also evaluated for presence of cancer, describing type of tumour, spread and grading of the lesion.We also work in close association with the Department of Oral Surgery for diagnosing and spearheading a community oral cancer diagnosis and screening program.
Our modern histopathological and microbiological lab is equipped with semi- automatic digital microtome, tissue processor, penta-head microscope , an updated IHC lab and a pathology museum with a collection of rare specimens.
The department is also actively conducting research in oral pre-cancer and cancer in collaboration with eminent institutions like SMST & ECE, IIT Kharagpur, ISI, JIS-ISAR, with publications in world-renowned journals like PNAS, Biomolecules MDPI, Global Oncology, Scientific Reports alongside numerous national and international pathology journals. Our department also boasts of ongoing projects funded by national agencies like ICMR,SERB and WB State DST.
