Our laboratory’s main goal is to explore the potential of novel methods for growth factor delivery, such as gene therapy, for restoring periodontal tissue lost due to oral disease. Working with investigators at the College of Engineering, we are able to immobilize PDGF and BMP adenoviral vectors onto various biomaterials for soft tissue and bone regeneration in vivo.
We also are investigating ways to improve outcomes for patients with implants. In addition to our studies examining increased implant osseointegration, we are researching new methods to incorporate periodontal ligament with alveolar bone and titanium.
Finally, the lab has been involved in clinical research studies that analyze oral fluids (whole saliva, crevicular fluid) in order to identify predictive markers of gingivitis, periodontal disease progression and peri-implant bone loss. By combining the levels of specific biomarkers together with the expression levels of certain bacteria within patient plaque samples, we are able to better determine the patient’s disease status resulting in a more effective treatment plan.

Dr. Giannobile is the Najjar Endowed Professor of Dentistry and Biomedical Engineering and Chair of the Department of Periodontics and Oral Medicine at the School of Dentistry. He received his DDS and an MS in Oral Biology from the University of Missouri. He later received his certificate in Periodontology and Doctor of Medical Science in Oral Biology from Harvard University. He subsequently completed postdoctoral training in Molecular Biology at the Dana Farber Cancer Institute and Harvard Medical School.
Dr. Giannobile previously served as a faculty member at Harvard and Forsyth Institute in Boston. He has published and lectured extensively in the fields of Regenerative Medicine, Tissue Engineering, and Salivary Diagnostics as it relates to periodontal and peri-implant reconstruction.
Dr. Giannobile is an Editor-in-Chief of the Journal of Dental Research and is on the editorial boards of multiple journals. He is a fellow of the American College of Dentists and a Diplomate of the American Board of Periodontology.

Non-invasive evaluation of facial crestal bone with ultrasonography.
PLoS One. 2017;12(2):e0171237

PURPOSE: Facial crestal bone level and dimension determine function and esthetics of dentition and dental implants. We have previously demonstrated that ultrasound can identify bony and soft tissue structures in the oral cavity. The aim of this study is to evaluate the accuracy of using ultrasound to measure facial crestal bone level and thickness.
MATERIALS AND METHODS: A commercially available medical ultrasound scanner, paired with a 14 MHz imaging probe was used to scan dental and periodontal tissues at the mid-facial site of each tooth on 6 fresh cadavers. The alveolar crest level in relation to the cemento-enamel junction and its thickness on ultrasound images were measured and compared to those on cone-beam computed tomography (CBCT) scans and/or direct measurements on a total of 144 teeth.
RESULTS: The mean crestal bone level measured by means of ultrasound, CBCT and direct measures was 2.66 ± 0.86 mm, 2.51 ± 0.82 mm, and 2.71 ± 1.04 mm, respectively. The mean crestal bone thickness was 0.71 ± 0.44 mm and 0.74 ± 0.34 mm, measured by means of ultrasound and CBCT, respectively. The correlations of the ultrasound readings to the other two methods were between 0.78 and 0.88. The mean absolute differences in crestal bone height and thickness between ultrasound and CBCT were 0.09 mm (-1.20 to 1.00 mm, p = 0.06) and 0.03 mm (-0.48 to 0.54 mm, p = 0.03), respectively.
CONCLUSION: Ultrasound was as accurate in determining alveolar bone level and its thickness as CBCT and direct measurements. Clinical trials will be required to further validate this non-ionizing and non-invasive method for determining facial crestal bone position and dimension.
