Research Interests

Charles Hildebolt is a Professor of Radiology at Mallinckrodt Institute of Radiology Washington University School of Medicine, an Adjunct Professor of Anthropology Washington University, an Adjunct Professor of Graduate Periodontics Saint Louis University, and biostatistical consultant Southern Illinois University School of Dental Medicine.  A focus of his research has been to improve methods for assessing alveolar bone loss caused by periodontal disease and to identify risk factors for alveolar bone loss and treatments that mitigate alveolar bone loss and periodontal disease.  He and his collaborators have identified geochemical substances that affect dental disease patterns and have developed methods that provide the most precise measurement of alveolar, crest-height loss that have so far been reported.  Among their finds are: (1) lumbar, femoral, and oral bone mass increase in postmenopausal women receiving hormone/estrogen replacement therapy, (2) alveolar bone height and postcranial bone mineral density are negatively affected by cigarette smoking and parity, (3) patients who take vitamin D and calcium supplementation have less severe periodontal disease than do patients who take no supplementation.

For 25 years, he and his colleagues have used 3D computed tomography (CT) in studies of (1) human variation in health and disease, (2) genetic and environmental contributions to variation in baboon cranial morphology, (3) brain expansion during hominid evolution (4) the brain of Taung (Australopithicus africanus), (5) the brain of Hadar early hominid AL 162-28, (6) the heritability of brain size and surface features in rhesus macaques, (7) the brain (and other cranial features) of Homo floresiensis (the Hobbit) and demonstrated that Homo floresiensis was not a diseased modern human.

He was treasurer (2009-2014) and is a fellow of the American Academy of Oral and Maxillofacial Radiology and is a fellow of the American Association for the Advancement of Science.  He serves on the editorial boards of Dentomaxillofacial Radiology and Calcified Tissue International And Musculoskeletal Research, was an associate editor for Oral Surgery, Oral Medicine, Oral Pathology, and Oral Radiology (2008-2014), and provides ad-hoc reviews for 14 other journals. He is a grant proposal reviewer for the NIH and 9 other foundations/agencies and is on the government affairs committee of the American Association for Dental Research. He has provided statistical support for a number of computed tomographic (CT), magnetic resonance (MR) imaging, and ultrasonography studies at the Mallinckrodt Institute of Radiology.
