Drs. Barry Pass and Martin D. Levin to Speak at National Institues of Science and Technology

Posted on May 29, 2017

The National Institute 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 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.


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 Dean”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 AAE?s Special Committee to Develop an Outcomes Consensus Conference. He is a contributor to the “Pathways of the Pulp,” and “Ingle’s Endodontics,” 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 to Present at the Society for Historical Archaeology

Posted on September 21, 2016

Dr. Levin examining the root canal of specimen JR 1225B in the Department of Biomedical Engineering lab at the Virginia Commonwealth University in Richmond, VA.

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.

Dr. Levin to Lecture at the 10th World Endodontic Congress

Posted on April 19, 2016

Dr. Levin, Adjunct Professor of Endodontics at the University of Pennsylvania, will present a keynote lecture and pre-congress workshop at the International Federation of Endodontic Associations in Cape Town, SA, 10th World Endodontic Congress.

His pre-congress workshop will highlight limited field of  view CBCT in Endodontics.  “In  endodontics, the region of interest is generally small and pre-­determined, favoring the selection of limited field of view (FOV) CBCT scans with lower x-­ radiation exposure, smaller volumes  to be interpreted and increased resolution.  All radiographs require careful and complete analysis because they may contain  findings that  affect the health of the patient. This hands-­on program will present a systematic method for navigating and documenting high resolution, limited FOV scans using multiple  clinical cases.”

Our Patients’ Words Mean a Lot to Us.

Posted on March 30, 2016

We love hearing from all of our patients. Experiences like the one below make our day, thanks for sharing.

“An Exceptional & Professional Experience

Please read this in its entirety and hopefully it will save you some time researching Dr. Jong and Bethesda-Chevy Chase Root Canal Specialists. You won’t go wrong choosing this endodontist.

I was on out of town business travel this week in DC when an excruciating toothache flared up in a tooth I had been previously advised might need a root canal. Being out of town, my primary dentist was unable to refer me to anyone in the area. I was extremely concerned about choosing the “wrong” endodontist. I was desperate, and in my extreme discomfort I researched scores of local endodontist practices, and decided on Dr. George Jong of Bethesda-Chevy Chase Root Canal Specialists. It was a chance but one I had to take.

After two days & nights of suffering, I called first thing in the morning and explained my circumstances. They rearranged scheduling to accommodate me with an appointment within several hours. 

As soon as I walked in, I was relieved to see a first rate, spotlessly clean, professional office and was greeted by especially helpful staff.  I was shown to the exam area which had all state of the art equipment, including video TV on the ceiling for the enjoyment of patients.

I was introduced to Dr. Jong who I cannot say enough about. He is one genuinely caring professional with a most calming demeanor who patiently explained everything to me before taking X-rays which were immediately shown to me on a big color screen. 

We went forward with the root canal procedure and although I had only had one performed prior to this, it was as pleasant and painless as I could imagine it could be. Dr. Jong kept updating me throughout the process as he knew I wanted to be. I have to say the video on the ceiling was especially helpful in helping the time pass for me.

Upon completion, Dr. Jong again explained everything to me. In addition to his high level of professionalism, he is an exceptionally nice person. When I left, he provided me with his cell phone # and asked that I please call if I experienced any complications. (I haven’t met another doctor who did that).

That evening, thankful for the relief he had provided, I was out to dinner when I received the following text message: “Hi Shane, Dr. Jong here. Just checking to make sure you are doing ok.”

That was the icing on the cake for me.

I highly recommend Dr. Jong and his staff if you need professional, caring and pleasant orthodontic care. He takes great pride in his work and it shows. I guess the only down side for me is that I will likely never see him again.

Thank you again Dr. Jong and staff. 

PS: When I returned to the Boston area and had the permanent crown completed by my (very particular) primary dentist, he made it a point to comment on what an exceptional done had been done on the root canal.”

Dr. Levin to speak at the Oregon Dental Conference, 2016

Posted on March 22, 2016

Dr. Levin has been invited to lecture at the Oregon Dental Conference to be held in Portland, WA on April 7-9, 2016. 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 3D structures, geometric distortion, magnification and the misrepresentation of structures. CBCT allows for the 3D assessment of odontogenic and non-odontogenic lesions, root canal morphology, revision treatment, root and alveolar fractures, resorptive lesions, anatomy prior to surgery and outcomes.

We Love Hearing From Our Patients!

Posted on February 15, 2016

The well being of our patients is what matters the most to us, as well as being there when you need us.

“I was sent to Dr. George Jong as an emergency case. He saw me immediately and cleaned out a very bad infection but noted  it was so deep that it would take more treatment before the root canal could be completed. He checked in with me several times and even opened up the office at night the next day when it appeared the antibiotics were not working and the infection was spreading. He is quick, efficient, and very gentle. His staff likewise. I had no pain in the treatment and could relax in the chair knowing I was in good hands. I only wish he was qualified to perform surgery on my shoulder, I’d use him immediately, I have that much confidence in him. And, he never lectured me about waiting so long to get the infection treated! He and his staff are keepers, I highly recommend them.”

Our team strives to provide professional and personalized endodontic care to our patients, and we very much enjoy sharing feedback from our patients like the one below.

“Listen, when you hear that you have to have a root canal, you’re understandably nervous. However, as soon as I walked into the office, Dr Mischenko and her staff put me completely at ease. They are the consumate pros. The procedure itself felt like it took no time at all, and I literally didn’t feel any discomfort during or after the procedure. It’s been about 16 months since I had the work done, and things couldn’t be better! I cannot reccomend dr Mischenko highly enough to anyone and everyone!”
