Department of General Practice

Harmeet Chiang, B.D.S., D.D.S., M.S., FAGD
My main research interest is in dental sleep medicine, especially obstructive sleep apnea (OSA). OSA is the stoppage of airflow during sleep. This treatable syndrome has many associated co-morbidities that can have severe detrimental effects on a person’s well being and general health. Though a diagnosis must be made by a medical doctor, the dental community can be a first line of defense to screen and even treat many of these people with oral appliance therapy (OAT).

Some of my other clinical interests have me involved in Silver diamine fluoride effects on dental caries; Vitamin D and its association with dental caries; CAD/CAM and self-assessment in dental education and Evidence based dentistry.

Julie Coe, D.D.S., M.S., M.B.A.
My current research interests range from informatics in business and clinical care, care delivery in interdisciplinary setting, and public health. Ongoing projects include developing comprehensive treatment planning software, designing airflow control system for cancer patients, and oral care in long term care facilities..

Terence A. Imbery, D.D.S.
I am interested in evaluating shear bond strength of different dentin bonding agents and composite materials. We have a reliable model for shear testing composite resin samples to enamel and dentin of extracted human teeth. Additionally, I have some experience in conducting surveys and questioners. I have also completed testing the D1 and D2 class for deficiencies in color vision using the Farnsworth-Munsell -100 Hue test and correlating their performance to dental shade matching.

Parthasarathy Madurantakam, D.D.S., M.D.S., Ph.D.
I am interested in bone tissue engineering, specifically on developing nanofibrous, electrospun scaffolds that are particularly intended for bone regeneration. Moreover, my collaborative research Matt Halquist in School of Pharmacy is exploring novel delivery vehicle for bone morphogenetic proteins (BMPs) from scaffolds as well as rapid and accurate detection of BMPs released using HPLC and Mass Spectrometry. On the clinical research front, I work closely with the department of periodontics in characterizing the biological and mechanical properties of platelet concentrates, specifically the platelet-rich fibrin (PRF). I am interested in applying the lessons learned from nature to develop better tissue engineering scaffolds.

I am also interested in exploring novel chairside sterilization techniques. In this front, I work closely with Dr. Todd Kitten in the Philips Institute of Oral Health Research. Finally I am committed to conducting clinical trials with the goal of contributing to the evidence regarding dental intervention

Vincent A. Sawicki, M.S., D.D.S., Ph.D.
I work with students on a broad range of research topics. Current projects include monitoring bacterial contamination of Dental Loupes Lighting systems.  Using selective media, we are researching the bacterial contamination of these systems as a bacterial reservoir for infection. We have demonstrated the presence of both S. mitis and S. salivarius on the lighting systems.  A concomitant survey of students' knowledge of Clinical Protocols for Operatory Use, and the possible cross contamination from dental loupes is being implemented.

Thomas Vahdani, D.D.S., FAGD
My current research projects focus on exploring the accuracy of conventional Impressions versus digital impressions in fixed prosthodontics.

Department of Oral and Maxillofacial Surgery

Dean M. DeLuke, D.D.S., M.B.A.
My interests include Oral Pathology, Syndromes of the Head and Neck, educational and curricular research, and business and medicolegal aspects of clinical practice. I am currently interested in developing a clinical trial to investigate bleeding following oral surgery in patients on the newer anticoagulant drugs (NOACs). I am conducting a review of osteonecrosis cases in conjunction with the radiation oncology department at VCU Medical Center. I am also developing a study in conjunction with Behavioral Sciences to investigate the predictive value of various criteria used in resident selection.
Publications

Shravan Renapurkar, D.M.D.
My main areas of research are in adult and pediatric temporo-mandibular joint disorders and maxillo-facial trauma. I am also interested in pediatric pathology including cysts, benign tumors and fibro-osseous lesions and craniofacial developmental abnormalities

Department of Orthodontics

Steven J. Lindauer, D.M.D., M.D.Sc.
I am involved in research concerning many aspects of orthodontics and orthodontic treatment. Specifically, I am interested in studying the esthetic aspects of orthodontic diagnosis and treatment, biomechanics, and orthodontic outcomes assessment. I also conduct research in the area of orthodontic biomaterials.

Bhavna Shroff, D.D.S., M.Dent.Sc., M.P.A.
I have a number of on-going research projects. The first one is a prospective small scale clinical trial that investigates the role of an electronic reminder on the compliance of patient with instructions given during orthodontic therapy. We wish to demonstrate that a reminder to wear rubber bands will increase the patient’s compliance. The second project investigates the differences in perceptions between metal orthodontic appliances and clear aligners by a population of prospective patients. We are currently working on a project looking at factors influencing the decision making process of initiating orthodontic treatment and the access to care.

Eser Tufekci, D.D.S., M.S., Ph.D., M.S.H.A.
My research focuses on orthodontic materials and clinical orthodontics. I am especially interested in the development of fluoride containing novel orthodontic materials that could be used to minimize the formation of white spot lesions in orthodontic patients with poor oral hygiene. Some of my clinical projects include use of digital technology in everyday orthodontic practice and orthodontic treatment outcomes.

Department of Pediatric Dentistry

Tegwyn Brickhouse, D.D.S., Ph.D.
I am interested in oral health disparities and health services research. I have conducted research on pediatric oral health measures, oral health disparities in publicly insured children, utilization of dental services in public programs, and early childhood caries prevention, as well as maternal influences on infant oral health. In 2015 I was awarded a 2.4 million dollar HRSA grant supporting the development of teledental treatment for underserved patients as well as interprofessional educational development for our residency program.

Elizabeth Berry, D.D.S., M.P.H., M.S.D.
I am interested in infant oral health education and early childhood caries prevention. A bridging theme throughout my public health work has been to increase access and utilization of dental services, including working with the School of Dentistry community, local pediatricians, and affiliated hospitals to provide the greatest amount of care possible.

Shillpa Naavaal, B.D.S., M.S., M.P.H.
I am interested in social determinants of oral health and health disparities in dental diseases and services utilization among children and adults. My current research work examines the impact of poor oral health on racial/ethnic and low income minorities and what role is played by dental insurance. I am also evaluating the effect of dental problems on the quality of life among adults with other health conditions.
Publications

Tiffany Williams, D.D.S., M.S.D.
My research has focused on the effect of Vitamin D and its relationship to early childhood caries. I have also studied prenatal risk factors for early childhood caries and sealant longevity.

Patrice B. Wunsch, D.D.S., M.S.
My interests are in pulp therapy for primary and young immature permanent teeth, with an emphasis on indirect pulp therapy as a vital pulp therapy technique. I am also interested in dental unit water line contamination, sleep apneas screening for adult and pediatric patients, early childhood caries and the special needs population.

Department of Periodontics

Janina Golob Deeb, D.D.S., M.S.
I am interested in studying changes that occur in in periodontal tissues and temporomandibular joint in aging mice using heterochronus repetitive bone marrow transplantation. It is of interest to determine whether transplantation of young bone marrow into older recipient mice could improve immune function and hence have an effect on changes that occur with ageing due to immunosenescence. Using  micro CT we will evaluate periodontal bone loss and analyze bone surfaces and intra-articular disks. After the radiologic study has been completed, tissues will be further examined microscopically.

Department of Prosthodontics

James P. Coffey, D.D.S., M.S.
I am collaborating with Dr. Hong Yeo of the VCU School of Engineering and Dr. Richard Costanzo of the VCU School of Medicine on an effort to develop a wireless electronic method to evaluate and monitor the chemical environment of the human oral environment.  We have received grant support from MEDRVA and Thomas F. and Kate Miller Jeffress Memorial Trust.

Chuck Janus, D.D.S., M.S., M.S.
Quality of care has always been an essential goal in practice. A review of the existing literature reveals little prior research on laboratory and dentist miscommunication over this aspect of tooth preparation. My research aims to survey the conceptions of laboratory technicians in regard to the optimum amount of clearance necessary for restorations of differing materials, and to address any discovered misunderstanding between what the dentists provide and what the technicians feel is necessary and potentially address any differences that indicate a need for revised standards or improved laboratory communication.
