Spring 2011 Edition of Dental Research - the research newsletter of the College of Dentistry at the University of Tennessee.
2011 Student Research New Department Day Research Spotlight: Chairs in the College of Dentistry Cranberries in Dental Research SUPPORTING THE In the College of Dentistry at the University of Tennessee, we have an obligation to instruct our dental students on the fundamentals of dentistry � both in prevention and treatment. We work to create within the students the knowledge base necessary to develop advanced skills to provide exceptional patient care. We pride ourselves � as a community-based institution � to instill in our students the desire to be engaged in public service projects to improve oral health in underserved populations. And, we give them opportunities for hands-on clinical experience with state-of-the-art technologies and procedures. But we strive to go beyond what is required or expected by a dental college � to give students graduating from UTHSC an edge in their careers, whether that be in private practice or academia. And we do this through research. In the UT College of Dentistry, students have the opportunity and are strongly encouraged to conduct a research project, under the direction of a faculty mentor, at least once during their four year tenure. Each summer, pre-doctoral students can apply to participate in the Student Summer Research Program, offered through the generous support of the Dental Alumni Association. Approximately ten to fifteen students are accepted into the program, based upon project merit, clinical significance, and feasibility. These students are awarded a stipend to carry out their projects and then present at one to two research conferences. MESSAGE from the SENIOR EXECUTIVE ASSOCIATE DEAN for RESEARCH OF DENTISTRY TODAY Dental Research Volume 1 Issue 3 Spring 2011 Franklin Garcia-Godoy, D.D.S., M.S. This program's importance also stretches beyond the student � enhancing the experience of the faculty mentors by introducing new perspectives into ongoing research, improving the policies and practices in the patient clinics, and heightening the engagement level throughout. Here at UTHSC, we are very proud and excited about what the future will bring with our student researchers! As is exemplified in this issue of Dental Research, students are taking advantage of this opportunity to gain research experience before graduating from UTHSC. Thirty-one students presented their research projects at the Annual Student Research Day held on the Memphis campus this past February. In addition, fourteen of those students also gave poster presentations at the Hinman Student Research Symposium that was held last October in Memphis and twelve students gave presentations at the annual American Association for Dental Research/International Association for Dental Research joint meeting held in San Diego in March. These students will take away from this experience more than just an increased knowledge of dentistry.

Puryear was mentored by Drs. Russell Wicks, Swati Ahuja, and Vinay Jain, all faculty in the Department of Prosthodontics. In October, Charles will represent UT in the student poster competition of the American Dental Association Annual Session in Las Vegas, Nevada. This award was sponsored by the Dentsply Corporation and was presented by Dr. Franklin Garcia-Godoy and Joshua Veltri, Key Account Manager for Dentsply North America. DENTAL ALUMNI APPROVE INCREASE to STUDENT RESEARCH PROGRAM In connection with the Mid-South Dental Congress, held this past March at the Hilton Memphis, the Dean's Executive Committee, comprised of dental alumni representatives, motioned to expand the support of the Student Summer Research Program. This motion was sent to the Board of Trustees of the Dental Alumni Association and was approved, which will increase funding to support more student projects. In addition, students will be offered a larger stipdend for their research projects. This increased funding will be assessed on a yearly basis to allow for the maximum number of students to participate in research during their predoctoral studies.

(From left) Mentors Dr. David Tipton, Dr. Jegdish Babu, and Dr. Franklin Garcia-Godoy with student researcher, Britney Taylor DEVELOPING a STANDARDIZED PROCESS for RESEARCH REPORTS and SUBMISSIONS As the dental research program grows at the University of Tennessee, it becomes important to create a standardized process for submitting and tracking grants/contracts, publications, and presentations. The following two guidelines are being developed to help improve the current system in the College of Dentistry. The first guideline applies to submitting grants and contracts, requesting that all grants and contracts paperwork be routed to the Grants & Clinical Research Coordinator (firstname.lastname@example.org) before it is routed to the Office of Research Administration (ORA). Currently, UTHSC has a five (5) working day policy where all grants and contracts paperwork must be received by ORA at least five working days prior to the official grant/contract deadline. This provides ORA staff with adequate time to review the documents and generate institutional approvals. This new guideline would ask all faculty/students submitting a grant/contract (including CDA, MTA) to submit that paperwork to the Grants & Clinical Research Coordinator seven (7) working days prior to the official deadline (two extra days before the ORA deadline). This will allow adequate time for department/college approvals to be obtained and will allow the Grants Coordinator time to review the grant (in particular the budget) and submit to ORA a standardized, polished grant/contract package. The second guideline applies to research activity tracking, requesting that all faculty members report their research activities to the Grants & Clinical Research Coordinator soon after they are realized. "Research activities" include grants (submitted and awarded), publications (submitted, accepted, electronically published ahead of print), presentations, and awards/honors (as they relate to research). Please send all the details of these activities, including all author/investigator names, titles, journal/book names, volume/issue/edition, and conference name, location, and dates. By efficiently providing this information to the Grants & Clinical Research Coordinator, these activities can be tracked more effectively and department, college, and university reports will be more accurate. * As a reminder, it is recommended that all researchers consult the Grants & Clinical Research Coordinator about the budget during the planning stages of the grants process. If you have any questions about these new guidelines, please contact Dr. Franklin Garcia-Godoy, Senior Executive Association Dean for Research (email@example.com) or Laurel Wedel, Grants & Clinical Research Coordinator (firstname.lastname@example.org). 6 NEW CHAIRS in the DEPARTMENTS of ENDODONTICS and RESTORATIVE DENTISTRY The Departments of Endodontics and Restorative Dentistry have both recently welcomed new chairs. College of Dentistry News Dr. Janet Harrison, D.D.S., is a professor in the Department of Restorative Dentistry (formerly known as Operative Dentistry). Dr. Harrison served as co-chair of the Operative and Endodontics Department and division chief of Operative Dentistry before accepting the chair position of the new stand-alone department in November 2010. Dr. Adam Lloyd, B.D.S., M.S. is an associate professor in the Department of Endodontics. Dr Lloyd played a vital role in the approval for the College to offer a graduate program in Endodontics and has been actively involved in research since he joined the dental faculty in September 2009. Dr. Lloyd accepted the chair position in February 2011. The College of Dentistry is excited to have Drs. Lloyd and Harrison in these administrative roles. Currently, the College is conducting a search for Chairs of the Department of Pediatric Dentistry and Community Oral Health and the Department of Orthodontics. Please visit: www.uthsc.edu/dentistry/Fac_Depts/jobs.php for more infomration on these positions. UT DENTAL ALUMNI ENDOWMENT for RESEARCH SPRING GRANT DEADLINE As a reminder to faculty and students - the UT Dental Alumni Endowment for Research will be accepting research grant proposals through Friday, April 29th. This request for proposals is a semi-annual competitive request with deadlines in April and October. Proposals for research must follow the guidelines set forth by the Dental Alumni (available by request from email@example.com) and must be submitted electronically to the Senior Executive Associate Dean for Research (firstname.lastname@example.org) or the Grants Coordinator (email@example.com) by 5:00 pm on the 29th. Please note recent changes to the guidelines for proposals to the Endowment for Research: � Clinical Significance: all proposals must include a short paragraph explaining the clinical relevance of the proposed research project. � Budget Consultation: when developing your budget for an Alumni Endowment for Research grant, you are strongly encouraged to consult with the Grants Coordinator to ensure that all necessary costs are included and that the budget is appropriate. � Outcome Measures: please include a plan for publication and presentation of research AND a plan for future funding should your research develop into an ongoing project. � Contingency Plan: this feature of the guidelines is not new but commonly neglected. Please describe your plan for research should any or all of the investigators be separated from the College of Dentistry for employment, graduation, or health reasons. � Cover Letter: this feature of the guidelines is also not new, but often overlooked. All grant proposals should include a cover letter, printed on letterhead and signed by all investigators. 7 As adjunctive periodontal therapy, essential oils and other plant products (i.e., cayenne, myrrh oil, tea tree oil, eucalyptol) have been used since antiquity to control mouth odor, pain, and inflammation associated with periodontal disease. Cranberry (Vaccinium macrocarpon), a native North American polyphenolic-rich fruit, which has been shown to inhibit human cancer cell line proliferation and prevent adherence of urinary tract infectious agents, may also be useful in the treatment/prevention of oral diseases. In vitro studies using a molecular-weight fraction of non-dialyzable material (NDM) prepared from cranberry juice, which is rich in proanthocyanidins, showed that the NDM inhibited the coaggregation of many oral bacteria and affected dental biofilm formation, and inhibited inflammatory activities of human macrophages and other cells. This research on the anti-adherence and anti-inflammatory activities of cranberry components has been the ongoing focus of the studies conducted by Dr. Jegdish Babu and Dr. David Tipton, both faculty in the Department of Bioscience Research. Initial Research Prior to 2009, Dr. Babu, in collaboration with Dr. Jacob Shiloah (Professor, Department of Periodontology) and Dr. Itzhak Ofek (Professor, Tel Aviv University) began the initial investigations of the effect of cranberry NDM on the removal of biofilm formation on hydroxyapatite discs. NDM was found to be extremely effective in detaching biofilm and preventing its formation. The research focus then shifted to the effect of NDM on Candida biofilm formation on dental acrylic products � formation that would cause stomatitis. Further studies during this time period revealed that NDM is bacteriostatic rather than bactericidal. In addition, these studies showed that NDM inhibited several constituents of dental biofilm (i.e., glycosyltransferase and fructosyltransferase) and the adhesion of Streptococcus sobrinus. Recent Research Since 2009, Drs. Babu and Tipton have worked under a grant from the Cranberry Institute to investigate the effects of cranberry components on denture-related stomatitis and inflammatory reactions of gingival fibroblasts in aggressive periodontitis. CRANBERRIES in DENTAL RESEARCH Research Spotlight Dr. Tipton and Nia Zacharia: Also supported by a stipend from the Dental Alumni Student Summer Research Program, Dr. Tipton, along with dental student Nia Zacharia, and in collaboration with Drs. Babu, Mustafa Dabbous (Bioscience Research), and Swati Rawal (Periodontology), conducted a study to investigate the role that cranberry NDM plays in the prevention and treatment of gingivitis and periodontitis. This study found that in aggressive periodontitis fibroblasts stimulated with products from bacteria that cause periodontal disease, cranberry NDM inhibited tissue-destructive matrix metalloproteinases (such as MMP-3) and a factor which promotes inflammation. In gingival epithelial cells, NDM inhibited expression of pro-inflammatory molecules (such as interleukin-6 and prostaglandin E. These results suggest that cranberry components may regulate oral fibroblast and epithelial cell inflammatory responses and may be useful as a host modulatory therapy (HMT) agent to prevent or treat gingivitis and periodontitis. New Projects Currently, Drs. Babu and Tipton are working with post-doctoral students to further explore the role of cranberry components on oral health. Dr. Tipton is working with Dr. Thomas Carter to explore how cranberry NDM interferes with cellular signaling pathways that stimulate IL-6 production in human gingival epithelial cells. Dr. Babu is working with Dr. Vreiti Sangha on a project that examines the effect of cranberry components on the biological activity of LPS molecule, in particular, the prevention and treatment of P.gingivalis-associated periodontal diseases. Drs. Tipton and Babu have also applied for continued funding from the Cranberry Institute to study the potential benefits of cranberry products in treating periodontitis in patients with diabetes mellitus. 8 Dr. Babu and Britney Sykes-Taylor: Supported by a stipend from the Dental Alumni Student Summer Research Program, Dr. Babu, along with dental student Britney Sykes Taylor, conducted a study to clarify and define more effective modes of preventing and treating oral inflammatory disease, such as denture-related stomatitis (DRS), which can result in pain, tissue destruction, and loss of function. DRS is caused by a tenacious inflammatory disease caused by the fungus Candida albicans. This study examined the effects of incorporating cranberry NDM into denture cleansers and tissue conditioners in an effort to see if NDM could prevent DRS by attacking and dissolving the safe-haven "biofilm" created by the fungal pathogen. Dr. Babu and Britney also studied the effect of NDM on the attachment of selected oral bacteria to saliva coated and uncoated titanium implant surfaces. The following is a list of current clinical research studies being conducted by UT College of Dentistry faculty. The title, investigators, and study objective are listed for each project.
