The International Congress of Dentists, Section XII (China) held their annual congress in Macau on June 18-20, 2018. Dr. Levin lectured on advances in the use of CBCT in endodontics. He talked about the value of an emerging technology: volumetric analysis of apical periodontitis in outcomes analysis.
At Jamestown, a team of archaeologists have exhumed the skull and teeth that may belong to Sir George Yeardley. He is best known for his role as a colonial governor who presided over the first representative assembly in the Western hemisphere. He was also one of America’s first slave owners. Yeardley died in 1627 at the age of 39 and was possibly buried in the second church’s central aisle – a place of honor.
The burial site was excavated by a team of archaeologists led by David Givens from Jamestown Rediscovery, museum curator Michael Lavin and forensic anthropologists from the Smithsonian’s National Museum of Natural History, led by Dr. Doug Owsley. They were joined by geneticist and archaeologist Turi King, from the University of Leicester. Dr. Levin assisted in the identification of the mandible and teeth found at the church. Additional scientific assessment to determine if the remains were Yeardley’s will be conducted in the coming months. Dr. D. Joshua Cohen, a scientist at Virginia Commonwealth University, will perform additional studies using micro-CT and scanning electron microscopy.

Dr. Levin has been invited to lecture at the Ottawa Dental Society’s Capital Dental Symposium III to be held in Ottawa, Canada on Friday, February 2, 2018. Dr. Levin will address the conference on the use of CBCT in endodontics and will base his program on the current literature. Central to his lecture are the limitations of intraoral radiography: compression of three-dimensional structures, geometric distortion, magnification and the misrepresentation of structures. Advantages of CBCT will also be discussed: three-dimensional assessment of odontogenic and non-odontogenic lesions, root canal morphology, revision treatment, root and alveolar fractures, resorptive lesions, anatomy prior to surgery and outcomes. This lecture will also describe new algorithms that allow clinicians to volumetrically measure lesions associated with apical periodontitis.
The National Institutes of Science and Technology (NIST) will host a seminar titled “Analyses of Dental Remains from 1607 Jamestown, Virginia using Micro-CT Imaging, SEM-EDX/Raman Spectroscopy and Paleobotany” on Wednesday, May 31, 2017. NIST forensic scientists and other invited guests will attend.
Presenters: Barry Pass, DDS, PhD, Howard University; Martin D. Levin, DMD, University of Pennsylvania
Abstract: The first English settlement in North America was established in 1607, at Jamestown, VA. The first casualty in Jamestown was a 15 year old boy, the apparent victim of an Indian attack. His excavated remains show an arrow head at the thigh, broken left collarbone, and anterior mandible with Ellis Type III fracture of mandibular left central incisor, with significant periapical pathological bone resorption. The objectives of this multidisciplinary study are to elucidate the nature and chronology of odontogenic cause(s) of mandibular pathosis evident in 1225B skeletal remains, and analyze contents of fractured teeth root canals to assist assembling a corporeal and physiological history. This case presentation will impact the forensic and archeological communities by demonstrating how evidence-based science and technology can improve efficiency, quality, accuracy, reliability, and functional excellence in forensic sciences.
Bios: Dr. Barry Pass is presently Professor of Oral Diagnosis and Radiology in the Howard University College of Dentistry and Graduate Professor in the Department of Physics and Astronomy. He has a PhD in physics, a DDS, completed post-graduate training in oral and maxillofacial radiology, and maintains a referral practice in that dental specialty. His past research interests were centered on using electron spin resonance in dental enamel for human radiation dosimetry of unintended exposures to ionizing radiation. Cohorts that he has studied include military participants of atomic weapons testing during and after WWII and victims of the Chernobyl nuclear disaster. Dr. Pass also maintains research interests in dental diagnostic imaging and is currently involved in forensic radiographic and spectroscopic studies of skeletal remains from the 1607 Jamestown Fort in Virginia.
Dr. Martin Levin is in private practice limited to endodontics in Chevy Chase, Maryland. He is Adjunct Professor of Endodontics and Chair of the Deanâ€™s Council at the University of Pennsylvania. He has served as Co-Chair of the Joint Special Committee on the Use of Cone Beam Computed Tomography, American Association of Endodontists and the American Academy of Oral and Maxillofacial Radiology. Dr. Levin is currently appointed to the AAEâ€™s Special Committee to Develop an Outcomes Consensus Conference. He is a contributor to the â€œPathways of the Pulp,â€ and â€œIngleâ€™s Endodontics,â€ as well as the author of numerous book chapters and peer-reviewed articles. Dr. Levin earned his degree in dental medicine and completed his endodontic training at the University of Pennsylvania. He is a Diplomate of the American Board of Endodontics.
Dr. Levin will address the USC International Endo Symposium in Los Angeles on December 8, 2017 on the use of CBCT in the volumetric analysis of apical periodontitis using post-processing software. The program will include open source software such as ITK-SNAP, Image J and 3DMeshMetric to determine the volumetric size of periapical lesions. According to Dr. Levin, this technology may improve our understanding of endodontic healing.

Archeologic sites are often damaged by weather and disruptions caused by subsequent populations, leaving small bone fragments to tell the story of their inhabitants. Skeletal remains at Jamestown are being scanned by Martin D. Levin, DMD, and Barry Pass, DDS, PhD, at the Jamestown Rediscovery lab with a Carestream Dental CS 3600 unit. The resulting scan files may lead to computer-aided reconstruction of the specimens in association with D. Joshua Cohen, MD, and his team at the Department of Biomedical Engineering, School of Engineering, Virginia Commonwealth University.
“This technology may provide an opportunity to image skeletal remains at archeological sites where small bone fragments are excavated,” Dr. Levin said.
The Society for Historical Archaeology has invited Martin D. Levin, DMD and D. Joshua Cohen, MD to present a lecture at their annual meeting, SHA 2017 Conference on Historical and Underwater Archaeology to be held on January 4-8, 2017 in Fort Worth, Texas. The title of the presentation is “A Detailed Analysis of the Dentition of Jamestown’s First Settlers.”
The lecture will highlight the work of archaeologists and an interdisciplinary team of researchers who are studying the skull and dentition of a 15-year-old boy (JR1225B) who appears to have been the victim of a battle with Native Americans during the initial settlement at Jamestown in 1607. Specimens recovered from the boy’s teeth and jaws yield clues about diet and other aspects of daily life in the 17th century.
Detailed study of the remains began with the morphological and temporal study of the skull and teeth using cone-beam computed tomography, intraoral radiography, micro computed, scanning electron microscopy, and Raman spectroscopy. The exposed root canal of the mandibular left central incisor and carious lesion provides a unique repository of particulate matter in the oral cavity and the associated intra-alveolar periapical lesion.
This research shows how advanced technologies can be used to characterize aspects of life and the disease state of skeletal remains.
The American Association of Endodontists (AAE) has asked Dr. Levin to join a newly formed Special Committee to Develop an Outcomes Consensus Conference. The work of the committee will be announced in upcoming communications from the association.
