Studies on Periodontal Disease

Dr. Daisuke Ekuni, DDS, PhD, is currently Lecturer, Okayama University Hospital, Department of Preventive Dentistry, Okayama, Japan where he also completed his DDS and PhD in Dental Science. He was a Post-Doctoral Fellow in the  Department of Oral Biological & Medical Sciences at the University of British Columbia, Vancouver, Canada. Dr. Ekuni is a member of several professional societies including the International Associate for Dental Research and the Japanese Society of Periodontology. Dr. Maurizio Battino, DSc, PhD, earned his DSc at the University of Bologna and his PhD in Biochemistry at the University of Catania, Italy. He was a Post-Doctoral Fellow at the University of Granada and is currently Associate Professor in Biochemistry at Università Politecnica delle Marche. He serves on the editorial boards of several journals including as Editor-in-Chief for Journal of Berry Research. His laboratory focuses on: the healthy effects of bioactive compounds in berries, honey and olive oil; unraveling the role of oxidative stress in the onset and development of periodontal diseases; and the mitochondrial role in genetic diseases. Dr. Takaaki Tomofuji, DDS, PhD, is Senior Assistant Professor, Okayama University Hospital, Department of Preventive Dentistry, Okayama, Japan. He was a Post-Doctorial Fellow at the Chonbuk National University, South Korea. He is a councilor of the Japanese Society for Dental Health and serves on the editorial board of  Journal of Dental Health. Dr. Edward E Putnins, DMD; Dip Perio; MRCD(C); MSc; PhD received his undergraduate and Periodontal training at The University of Manitoba prior to completion of his PhD at The University of British Columbia. He is a professor and serves as Associate Dean of Research, Graduate and Postgraduate Studies at The University of British Columbia. Dr. Putnins’ laboratory has two principal areas of focus: (1) examining whether novel bonemarrow stromal cell expansion strategies can be developed to regenerate lost hard and soft periodontal tissues; and (2) regulating epithelial cell barrier integrity and proliferation with respect to periodontal disease pathogenesis.
