Course Description
Join us for a day exploring the latest information in oral radiology with presentations
from five experts in the field. With a vast array of topics, you are sure to come away with
new information and techniques to put into practice Monday morning. We will also
celebrate the contribution of Lars Hollender, DDS, PhD to the world of oral radiology,
and his reaching the milestones of his 80th birthday and 30 years of service at the
University of Washington.
Robert Langlais, DDS – Head and Neck Pathology
This presentation will review the imaging characteristics of representative pathology
arising in various anatomic regions of the head and neck. These may be included in the
CBCT scan depending on the volume size and location selected by the user. The
anatomic regions to be covered will include the nose, sinuses, airway, clivus, cervical
spine, salivary glands, cystic lesions of the neck, cranial calcifications, temporal bone and
orbit. Appropriate follow-up imaging modalities will be illustrated as needed.
Course Objectives: As a result of attending this lecture, you will be able to:



Review example pathologies in various anatomic regions potentially included in a
CBCT scan.
Interpret CBCT imaging features of selected pathologies as they affect specific
anatomic regions.
Recognize additional diagnostic imaging modalities obtainable by follow-up
imaging modalities
John Ludlow, DDS, MS, FDS RCSED – Imaging in Dentistry Today: Optimizing
Diagnostic Opportunities – Minimizing Potential Risks
What are the risks of maxillofacial radiographic imagine? Are concerns about risks from
diagnostic imaging justified? Which dose reducing strategies are most effective and costeffective? These are a few of the questions commonly asked by dentists that will be
addressed in this presentation. Other questions include:






How is risk related to dose?
How do we calculate dose?
Why do I hear seemingly contradictory statements that dental imaging has
become either more or less risky?
What doses are associated with different techniques used for dental imaging?
What can we do to reduce patient dose?
How should I discuss risk with my patients or their parents?
Course Objectives: As a result of attending this lecture, you will be able to:



Characterize the risks from ionizing radiation that result from dental and
maxillofacial examinations
Understand where dental x-ray exposure fits in with other sources of exposure to
inonizing radiation as a population risk
Describe options in radiographic equipment (with emphasis on cone beam
technology) and how these influence image and dose characteristics


Explore ways to reduce the risks from diagnostic imaging through radiographic
selection criteria, patient shielding, and technical factor selection.
Explain how to talk about x-ray risks and benefits with patients and parents
Alan Lurie, DDS, PhD – Detection of Osteoporosis by Quantitative Imaging: History
and Oral and Maxillofacial Imaging Contributions
This lecture will introduce the nature of the global problem of osteoporosis, trace the use
of quantitative imaging in the detection and classification of osteopenia and osteoporosis,
and examine the contributions of various types of Oral and Maxillofacial (OMF) imaging
to the detection and treatment of this disease.
Course Objectives: As a result of attending this lecture, you will be able to:


Discuss the nature of osteoporosis, its adverse outcomes, and the history of
quantitative imaging in the detection and characterization of the disease
Recognize the contributions of various types of OMF imaging, including
intraoral, panoramic and cone beam CT imaging, on the diagnosis and staging of
osteoporosis
Axel Ruprecht, DDS, MScD, FRCD(C) – Anatomy on CBCT: The Roadmap of the
Maxillofacial Region and Surroundings
This lecture will show the major anatomical structures seen on cone beam CT images in
the standard planes and reconstructions as the person interpreting the images would
encounter them on going through the dataset.
Course Objectives: As a result of attending this lecture, you will be able to:



Appreciate the complexity of the head and neck osseous anatomy on CBCTs
Recognize the appearance of the various anatomical structures seen on
multiplanar reconstructions
Discuss the appearance of the various anatomical structures on panoramic and
orthoradial reconstructions
Gerard Sanderink, DDS, PhD – Cephalometric and Panoramic Radiography:
Nothing New?
Since the introduction of digital imaging in Cephalometric and Panoramic Radiography,
more possibilities became available to reduce doses even more than most of us are aware.
In Direct Digital Panoramic Radiography new tools made it possible to influence the
position and shape of the image layer. For a better understanding of the characteristics, a
revision of the definition of the “Focal Trough” is needed and demonstrated with help of
animations. For panoramic images, although spectacular improvement in image quality
is obtained, the diagnostic value is still not comparable with intraoral radiographs.
Distortion in these new images is also a recurrent problem which makes them inaccurate
for measurements. Knowledge of image formation also gives a better understanding of
the reproduction of anatomical structures on these panoramic images. A CAL software
program was developed to improve these skills and will be demonstrated.
Course Objectives: As a result of attending this lecture, you will be able to:






Achieve dose reduction in Cephalometric Radiography
Reduce patient dose in Panoramic Radiography in a simple manner
Share a better understanding of the so called “Focal Trough”
Discuss the possibilities of direct digital panoramic machines
Recognize the limitations of the image quality
Identify anatomical landmarks on panoramic images
