Lessons from endodontics:
Advantages of adopting new

NEW DENTAL TECHNOLOGIES are constantly being developed, and clinicians
must decide which innovations best fit their individual needs. I pride myself on
being on the “leading” edge of technology, but not the “bleeding” edge. This means
I implement products that are supported by scientific research and proven to be
clinically viable. In this article, I am going to share products and technologies that
have helped distinguish my practice, particularly in regard to visualization.
As an endodontic specialist, I feel the need to go above
and beyond to provide quality treatment. In many respects,
patients also have higher expectations of me as an endodontist. By adopting advancements in the following three
areas of technology, our practice has improved the quality
of treatment and met patient expectations:
• Magnification and illumination
• 2-D digital imaging
• 3-D imaging/cone beam computed tomography (CBC T)
MAGNIFICATION AND ILLUMINATION
A good microscope with powerful illumination is impera-
tive technology for endodontists (figure 1). It has been
shown repeatedly in the research that the dental operating
microscope allows practitioners to locate anatomy at a
far greater success rate compared to the unaided eye.
This allows one to be minimally invasive during root canal
procedures. This benefits the referring dentist, who is left
with more tooth structure for the restoration.
When microscopy was introduced in the 1990s, clinicians were resistant to use it. They challenged whether
the expense was justified and whether outcomes would
be better. Now, microscopy has evolved to be one of our
standards of care that few specialists will work without.
I personally rely on a dental microscope from Global
The same concept is true with other types of technology.
Dental practices have evolved from using traditional film
to 2-D digital radiography and 3-D CBCT. With each
advancement, the view of the anatomy becomes appreciably more detailed.
Because endodontics necessitates capturing a fair
number of radiographs, endodontists appreciate 2-D
digital imaging because it requires a lower amount of
radiation than traditional film radiography. Such is the
case with my DEXIS system ( figure 2). Studies have shown
that capturing one view of a tooth garners only a limited
percentage of information, but both a straight-on view
and an angled view results in a greater amount of details.
Also, in a digital format, quick access to the data results
in more efficient use of time.
During endodontic treatment, I may need a “check”
radiograph to see if I am in the proper length for a root
canal, or if I am in the proper orientation for access. My
digital system allows me to quickly capture an image. For
these check radiographs, DEXIS provides sensor holders
