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 three 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.
Upon completion of this CE webinar, participants will be able to
• Describe how CBCT is a useful adjunct in addition to 2D radiology
• Practice conveying the importance of CBCT to patients
• Identify how to review and analyze limited field of view 3D scans for endodontic applications
• Recognize how CBCT can help in the assessment of endodontic case complexity
