3-D imaging has blazed a new frontier for endodontists. Cone beam images provide a wealth of additional information that was previously undetectable with other imaging methods, providing the necessary information to solve the most challenging dental mysteries. The non-distorted, cross-sectional view (see image above) provided by the scan, plus the ability to rotate the image and view the dentition from many angles, addresses issues related to many facets of our specialty and even prevents unnecessary or premature procedures. Adding cone beam imaging to the endodontist's "tool box" provides the additional knowledge needed to deal with many different and often difficult situations we face every day.

Investigation at its best
For example, while 2-D images are fine for viewing apical areas; buccal and lingual areas present more of a challenge. Endodontists can better detect resorption with the additional ability to view the teeth from other angles and in relation to other anatomical structures. In some cases, we can utilize definitive treatment outcomes if we can detect small cracks, hidden canals, or even foreign bodies. Before restorations, 3-D scans give insight into how far decay has traveled into the bone, without performing unnecessary exploratory surgery on the patient. Miniscule infections that cause pain and delay treatment are also much more discernable on a 3-D scan than 2-D radiographs.
Better communication
Cone beam offers yet another benefit. With all the facts clearly visible on their scan, patients are more likely to understand and accept treatment.
Higher efficiency
Besides its clinical advantages, 3-D radiographic imaging also offers economic benefits. The efficiency of the cone beam imaging process can result in shorter appointments, allowing more treatments in a schedule day.
Continued learning
Knowledge is power. As new applications for Conebeam radiography continue to evolve, continuing education is imperative for general and specialty practices who want to reap the benefits. My system's manufacturer (Gendex, GXCB-500 )offers a wide variety of courses for dentists considering the technology and for those owners who what to expand its uses.
