The Giannobile laboratory explores the potential of novel methods of growth factor delivery such as gene therapy to stimulate periodontal tissue repair. In addition, the lab is involved in clinical research to develop predictive markers of periodontal and peri-implant bone loss.

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. Dr. Giannobile currently serves as president of the American Academy of Periodontology Foundation.
Dr. Giannobile also serves as a consultant to the National Institutes of Health. To read more about Dr. Giannobile as an NIDCR investigator, please visit the NIDCR website for an article on the future impact of research on periodontal disease.

Integration of 3D Printed and Micropatterned Polycaprolactone Scaffolds for Guidance of Oriented Collagenous Tissue Formation In Vivo.
Adv Healthc Mater. 2016 Jan 28;
Authors: Pilipchuk SP, Monje A, Jiao Y, Hao J, Kruger L, Flanagan CL, Hollister SJ, Giannobile WV
Scaffold design incorporating multiscale cues for clinically relevant, aligned tissue regeneration has potential to improve structural and functional integrity of multitissue interfaces. The objective of this preclinical study is to develop poly(ε-caprolactone) (PCL) scaffolds with mesoscale and microscale architectural cues specific to human ligament progenitor cells and assess their ability to form aligned bone-ligament-cementum complexes in vivo. PCL scaffolds are designed to integrate a 3D printed bone region with a micropatterned PCL thin film consisting of grooved pillars. The patterned film region is seeded with human ligament cells, fibroblasts transduced with bone morphogenetic protein-7 genes seeded within the bone region, and a tooth dentin segment positioned on the ligament region prior to subcutaneous implantation into a murine model. Results indicate increased tissue alignment in vivo using micropatterned PCL films, compared to random-porous PCL. At week 6, 30 μm groove depth significantly enhances oriented collagen fiber thickness, overall cell alignment, and nuclear elongation relative to 10 μm groove depth. This study demonstrates for the first time that scaffolds with combined hierarchical mesoscale and microscale features can align cells in vivo for oral tissue repair with potential for improving the regenerative response of other bone-ligament complexes.

Effects of Triclosan on Host Response and Microbial Biomarkers during Experimental Gingivitis.
J Clin Periodontol. 2016 Jan 28;
Authors: Pancer BA, Kott D, Sugai JV, Panagakos FS, Braun TM, Teles RP, Giannobile WV, Kinney JS
AIM: This exploratory randomized, controlled clinical trial sought to evaluate anti-inflammatory and -microbial effects of triclosan during experimental gingivitis as assessed by host response biomarkers and biofilm microbial pathogens.
MATERIALS AND METHODS: Thirty participants were randomized to triclosan or control dentifrice groups who ceased homecare for 21 days in an experimental gingivitis (EG) protocol. Plaque and gingival indices and saliva, plaque, and gingival crevicular fluid (GCF) were assessed/collected at days 0, 14, 21 and 35. Levels and proportions of 40 bacterial species from plaque samples were determined using checkerboard DNA-DNA hybridization. Ten biomarkers associated with inflammation, matrix degradation, and host protection were measured from GCF and saliva and analyzed using a multiplex array. Participants were stratified as 'high' or 'low' responders based on gingival index and GCF biomarkers and bacterial biofilm were combined to generate receiver operating characteristic curves and predict gingivitis susceptibility.
RESULTS: No differences in mean PI and GI values were observed between groups and non-significant trends of reduction of host response biomarkers with triclosan treatment. Triclosan significantly reduced levels of A. actinomycetemcomitans and P. gingivalis during induction of gingivitis.
CONCLUSIONS: Triclosan reduced microbial levels during gingivitis development (ClinicalTrials. gov NCT01799226). This article is protected by copyright. All rights reserved.
