An essential component of the diagnostic puzzle in endodontics is radiology. 2D radiographs have been helpful to aid in diagnosis and planning. However, teeth, like the human body, are 3 dimensional and limitations with 2D radiology exist. Ultimately, the use of 3D imaging/CBCT in endodontics is about avoiding surprises, assessing prognosis, and having the information to treatment plan most effectively. Studies have shown that endodontists change their treatment plan approximately 60% of the time when using 3D imaging vs. 2D imaging.
Some examples of CBCT’s use in endodontics are identifying significant splits/branches on canals that don’t show on 2D; assessing the number, shape, and location of canals (commonly lower anteriors, premolars, and molars); locating and planning access to calcified/missed canals, angled/rotated teeth, crowned teeth or difficult anatomy; and more accurately measuring for location to a canal (depth, distance from other canals or structures, etc). Additionally CBCT can help to minimize incomplete endos (CDT D3332) - entering and finding a crack/perforation. 3D imaging also provides another diagnostic modality for more challenging patients (gaggers, special needs, etc) and is a vehicle that can provide better patient communication - reviewing the scan with the asymptomatic patient.
- Understand how CBCT is a useful adjunct in addition to 2D radiology
- Understand how to convey the importance of CBCT to patients
- Understand how to review and analyze limited field of view 3D scans for endodontic applications
- Understand how CBCT can help in the assessment of endodontic case complexity and treatment planning.

Dr. Judy McIntyre obtained her DMD from the Harvard School of Dental Medicine, where she performed research on dental unit waterline biofilms in conjunction with UCLA. She then completed her endodontic residency at the University of North Carolina at Chapel Hill. Alongside renowned researchers in the field of endodontics, traumatology and pediatric dentistry, her research regarding traumatic dental injuries has been published in numerous professional journals.
Dr. McIntyre loves teaching and sharing her passion of trauma and endodontics with other dentists. Especially among pediatric patients, she employs unconventional treatment modalities from her training to do whatever she can, when possible, to save a tooth.
