Treatment planning for diseased teeth is often complex and requires a detailed dental history, clinical testing, and thorough radiographic evaluation.
The introduction of three-dimensional imaging, specifically limited field of view (FOV) cone beam computed tomography (CBCT), has revolutionized endodontic treatment planning.✨
According to the Joint Position Statement of the American Association of Endodontists and the American Academy of Oral and Maxillofacial Radiology, limited FOV CBCT is the imaging modality of choice for evaluating nonhealing after prior root canal therapy, especially in retreatment cases.📊
Compared to larger FOV devices, limited FOV CBCT offers higher resolution with less radiation exposure, making it ideal for targeted diagnostics. It allows clinicians to perform selective root retreatment, focusing only on roots showing signs of disease—something often missed on traditional 2D radiographs.🔍
In fact, studies have shown that when CBCT data was added to existing diagnostic information, treatment plans changed in 35% to 62% of cases. That’s a major shift driven by better visibility and accuracy!📈
CBCT also aids in detecting:
🟣 Missed or untreated canals
🟣 Root perforations
🟣 Complex anatomical variations (fins, fused roots)
🟣 Quality of instrumentation and obturation
Bone loss patterns consistent with apical or marginal periodontitis, furcation involvement, or root fractures.
By identifying these factors early, CBCT helps clinicians avoid pursuing retreatments with poor prognoses, saving time, resources, and frustration for both dentist and patient.
