lecture and dental tools icon Lecture & Hands-on

In an effort to mitigate the risk of being exposed to the Coronavirus, this course will be postponed. We are working with the speakers and campus facilities to identify a new date.


Dental radiography involves the use of ionizing radiation and thus it is essential that all dental personnel maintain knowledge of radiographic techniques and radiation safety to perform clinical procedures.

This course will review current knowledge of radiation safety, ALARA principle and protection as well as dose reduction technique. With the widely use of solid state digital detectors (digital sensors), we will compare intraoral sensors. Proper use of handheld portable X-ray device (Nomad) will be discussed. We will review sensor and tube head placement technique and allow time for progressive self assessment throughout the course. Participants will have opportunity to practice using both conventional wall-mount X-ray unit and portable X ray device (Nomad) to acquire intraoral radiographs.

This course will also review concepts of panoramic radiography. We will discuss problems commonly associated with panoramic technique and review steps for positioning a patient for panoramic radiography. This part of the course will focus on common errors that are often seen on the panoramic image which decrease the diagnostic quality and provide solutions on how to correct these errors.

Course Objectives:

As a result of attending this session, you will be able to:

  • Become aware of the danger of dose creep and know how to achieve dose reduction
  • Use rectangular collimation to take intraoral radiographs
  • Use digital sensor positioners and adapt sensor placement to improve patient comfort
  • Place and expose digital radiographs on a skull
  • Apply techniques to eliminate cone cut, overlapping, elongation and foreshortening
  • Evaluate the images for diagnostic quality and learn how to correct the errors
  • Determine when it is necessary to re-take a radiograph
  • Use handheld portable X-ray device (Nomad) correctly
  • Perform infection control procedures related to radiology
  • Review panoramic radiographs and Identify technique errors and how to correct these errors.


Dr. Peggy LeePeggy Lee is the Director of Oral Maxillofacial Radiology Residency Program and Assistant Professor in Oral Radiology at the University of Washington Dental School.

Dr. Lee received her dental degree in Taiwan and completed an MSD in oral medicine at the University of Washington in 1984, where she specialized in TMD, pain, and diseases of the oral facial complex. She also earned a PhD at the University of Washington studying HIV followed by post-doctoral training in immune system development at the University of Washington and at the University of California – San Diego. She returned to the UW Dental School in 2006 to teach radiology, including radiographic technique and interpretation. After completing the Oral and Maxillofacial Radiology residency program in 2012, she served as assistant program director and became program director in 2019.

Dr. Lee is board certified in oral and maxillofacial radiology. She has published numerous peer-reviewed articles, given local, national, and international presentations on radiographic interpretation and CBCT imaging, and served as a peer-reviewer for several radiology journals. In addition to spending time entertaining her dogs, she enjoys sailing, climbing, mountain biking, backcountry skiing and traveling.

Dr. Andrew NalleyAndrew Nalley originally grew up in Houston, Texas where he also received his degree at University of Texas School of Dentistry. Upon graduating, he joined a private practice for 5 years, where he utilized CBCT and developed an increasing interest in the field of radiology. To pursue his passion, Dr. Nalley moved to Seattle to attend the Oral and Maxillofacial Radiology residency program at University of Washington. He is currently working on his research on TMJ findings on CT and MRI in hopes to expand the knowledge surrounding TMJ. After completing residency, he stayed on as faculty as the dental radiology clinic director at University of Washington School of Dentistry. Although Dr. Nalley’s passion remains in radiology, he also loves general dentistry and works part time at a private practice in the Seattle area. Outside of dentistry and radiology, Dr. Nalley enjoys spending time outdoors, hiking and photography.

Dr. Stuart TaylorStuart Taylor grew up in the United Kingdom, and graduated from Dental School at the University of Manchester, UK in 2000. After several years of private practice in the UK, he moved to the USA and completed an MSD in Oral Medicine at the University of Washington in 2009. He then went on to complete the Oral and Maxillofacial Radiology Residency Program at UW in 2013. He is a Diplomate of both the American Board of Oral Medicine and the American Board of Oral and Maxillofacial Radiology. He is currently the Director of the Oral Diagnosis and Treatment Planning Clerkship at the UW Dental School.

Dr. Taylor is an active member of Faculty at the UW and involved in teaching the current UW dental students. His interests include the early diagnosis of oral cancer and emerging imaging techniques for oral mucosa.
