Background of the Department

In 1998 the Department of Oral Biology was established at AB Shetty Memorial Institute of Dental Sciences (ABSMIDS) under Mangalore University of Karnataka state. The Department of Oral Biology is first of its kind introduced and established in India. In order to develop the Department of Oral Biology, Professor Chitta Chowdhury took a leading role after his return from Japan where he was working as a faculty at Okayama University after completion his PhD from Asahi University and Postdoctoral fellowship. The Nitte Education Trust recruited and offered him a senior Professor position at AB Shetty Memorial Institute Dental Sciences in 1997. Founding Dean of AB SMIDS Professor (Dr.) N. Shridhar Shetty was leasing to get this specialty of Oral Biology which was incepted by Professor Chowdhury. Until 2002 the department was running with its various activities under Rajiv Gandhi University of Health Sciences of Bangalore. During the period the department completed 15 research projects and established a unit for oral cancer screening and education, which has been documented in a published book and research jointly by Nitte (Deemed to be University) India and Bournemouth University, England- the book is catalogued in major University libraries of the world.( review in British Dental Journal: https://www.nature.com/bdj/journal/v210/n9/full/sj.bdj.2011.380.htm ). .The department carried out its activities in collaboration with other departments when Professor Chowdhury went to UK with an assignment to develop international centre for tropical oral health at Bournemouth University and Poole NHS Hospital of Dorset, England. Nevertheless, the activities went on to progressing in a pace by the participation of the faculties and under a voluntary supervision and yearly visits of Professor Chowdhury.

Ongoing activities within re-shaped Oral Biology & Genomic Studies (OBGS)| [Gene and Genetic studies]

However, since last four years the department has been re-shaped and re-named as the Department of Oral Biology and Genomic Studies (OBGS), and at present it is running in different direction under the leadership of founding head and with the help of in-house supporting and collaborating faculties. Currently the Department of OBGS is running various important research projects and several intra-mural and extramural activities, of them research related to Fluoride, Cariology, Diabetes Mellitus, chronic obstructive pulmonary disease (COPD) and its impact on oral health, mineralised tissue research and imaging are worth mentioning. But the main focus and the pivotal activity of the department is Oral Cancer Prevention and Control, and with this, the unit is rightly operating an extraordinary nicotine replacement therapy (NRT) services –comprising NRT clinical practice, training sessions and tobacco related addiction researches. The service helps prevent tobacco related pre-mature deaths and disabilities . Moreover, number of projects related to educational development and action –oriented programmes are on-progress. Specifically the department focuses, cost-effective oral cancer screening, molecular interventions for prevention and control of oral-head-neck cancer.

Gene - genomics & stem cell
The oral cancer unit aims to identify unique Tumor Suppressor Genes (its deletions and mutations) which is associated mainly with smokeless tobacco (ST) habits — killing millions of Central and South East Asian population and the pilot research has been published. https://www.ncbi.nlm.nih.gov/labs/articles/18057857/ . Japan Society for Promotion of Science (JSPS) supported another molecular research on Angiogenesisis and Lymphynogenesis of Oral cancer—a comparative profile of Indian and Japanese cases has been published https://www.ncbi.nlm.nih.gov/labs/articles/22994737/ A project is undergoing to search the functional stem cell in oral squamous cell carcinoma in order to determine for a quantification which may help develop a prognostic application. Another piloting has been persuaded in collaboration with Applied zoology department of Mangalore University to find-out a link of specific Gene(s) for causation of Fluorosis -- is under preparation to publish

Nitte (Deemed to be University) Fund and partly ICMR student fund supported research on Oral Health Status among Chronic Obstructive Pulmonary Disease (COPD) cases has been reported in the World Congress of International Association of Dental research, New Delhi, 2017

Title. Fluoride in fish flesh, fish bone and regular diet in south-coastal area of Karnataka state of India
The study aimed to estimate the fluoride content in regular food items available, including fish, in a coastal area of the South Karnataka state of India in order to develop recommended daily allowance (RDA) of fluoride from different food items largely consumed by people in Karnataka. In the study, the division of Fluoride and Health of the department of Oral Biology and Genomic Studies finds that, the highest concentration was estimated 3.16 ppm in Rohu fish flesh, and 7 ppm in rava dosa (a vegetarian food). Therefore, the Rohu (Labeo rohita) fish contains higher concentrations of fluoride in bone Fluoride determined in fish-flesh was also high in concentration 2.28 ppm. Among the regular food items, rava dosa has high concentration of Fluoride

The study entitled by " Highly acidic pH values of carbonated sweet drinks, fruit juices, mineral waters and unregulated fluoride levels in oral care products and drinks in India: a public health concern."

The Research Outcome Published in UK based Journal Perspective in Public Health Of the wide variety of dentifrices and tooth-powders available in India, most brands do not indicate the fluoride levels on their packaging or inserts. Similarly, the unregulated acidic pH values of carbonated sweet drinks are not only potentially contributing to non-carious tooth loss (enamel erosion and dentine erosion), but are also a contributing factor to the weight gain observed in Indian adolescents.

Nicotine Replacement Therapy (NRT)

Service provisions
1. Clinical Services: Nicotine Replacement Therapy services to clients who are nicotine dependant and addicted to Cigarettes/Beedi/Smokeless tobacco.

Assessment of personal habits for counselling, NRT services and addiction research is done in following steps:

A detailed case-history has to be recorded, diagnosed and studied for the sole purpose of maintaining a record. Particulars such as name, age, gender and address are mandatory. Added on information such as number of cigarettes/ Beedi / other tobacco product (eg smokeless tobacco- ST) used, should be taken into account. This helps the interviewer to maintain a good rapport with the tobacco users, and that helps achieve the goal of stopping tobacco at the earliest.

Assessment and Monitoring
A survey is conducted to understand about smoking habits and to develop a client-friendly stop tobacco program. The survey format, with criteria for assessment will be used. Assessment using KAP indices (Knowledge, Attitude and Practice)

The study aims
To estimate the level of knowledge concerning tobacco usage and other associated habits.
To investigate the attitudes towards tobacco usage and other associated habits.
To record the practice of tobacco usage and other associated habits.
Fagerstrom Test for Nicotine Dependence (FTND indices) is used to score a patient’s level of nicotine dependence. Entry of the file (computer coded Microsoft Excel format)

All the information collected has to be tabulated, designed and computed in a computer – coded system. Maintaining a record helps the investigator with the progression of the study and to arrive at a conclusion. The purpose of this system is patient referral and follow-up.

Examination and Assessment process consists of the following:
Measurement of blood pressure

Title: IIIs there a justification for cone beam computed tomography for assessment of proximity of mandibular first and second molars to the inferior alveolar canal: A systematic review

It has been concluded that, the average mean distance between the IAC and the apices of mandibular molars is approximately 7.3 mm. In addition to this, certain factors, such as age, sex, race, position of tooth and bone thickness, play a key role in determining the distance between the IAC and the apex. The values found are mean values and the clinical decision should be made on a case by-case basis and the type of imaging modality used. There is significant application of CBCT in clinical outcome while treatment planning in clinical outcome while treatment planning in the first and second mandibular molar region.
