CBCT viewer for endodontists — root canal imaging in the browser

Sub-millimeter measurement to the apex

Measure working length and canal curvature directly on the CBCT slice, calibrated from the DICOM voxel size — not a scaled printout or a ruler held up to a monitor.

Cross-sections at any angle through small FOV CBCT

Scroll axial, sagittal and coronal planes and build oblique cross-sections perpendicular to the canal to separate roots that overlap on a 2D image.

Periapical lesion sizing

Outline and measure periapical radiolucencies in three planes to track healing between the pre-treatment and recall CBCT.

Vertical root fracture screening

Cross-sections perpendicular to the root reveal the fracture line and the characteristic J-shaped bone loss pattern that periapical radiographs cannot show.

Accessory canal and isthmus detection

Scroll thin axial slices through the coronal and middle third of the root to identify isthmuses between canals before access.

Root resorption classification

Differentiate internal from external resorption by comparing axial and sagittal cross-sections at the defect site.

Pre-treatment canal mapping

1. 1.Open the small FOV CBCT for the tooth in question.
2. 2.Scroll axial slices at the coronal, middle and apical third.
3. 3.Identify canal number, curvature and isthmus location before access.
4. 4.Measure estimated working length as a reference for the apex locator.

Vertical root fracture rule-out

1. 1.Build oblique cross-sections perpendicular to the suspected root.
2. 2.Scroll through the full root length looking for a fracture line.
3. 3.Check for J-shaped radiolucency along the lateral bone.
4. 4.Compare with the periodontal probing pattern before deciding on extraction.

Periapical lesion follow-up

1. 1.Open the pre-operative CBCT and the recall CBCT side by side.
2. 2.Align the same slice position on both studies.
3. 3.Measure lesion diameter in axial and sagittal planes on each visit.
4. 4.Export a PDF with both measurements for the patient chart.

Retreatment with suspected missed canal

1. 1.Review the existing radiograph alongside a new small FOV CBCT.
2. 2.Scroll cross-sections at the level of the pulp chamber floor.
3. 3.Look for canal orifices not visible on the original access.
4. 4.Share the finding with the referring dentist via link before starting.

Does CBCTHub replace 2D periapical radiographs?

No. Periapical radiographs remain the first-line image for most endodontic exams. CBCTHub is where you open the CBCT once a 2D finding is ambiguous — suspected extra canal, unresolved periapical radiolucency, vertical root fracture, or a failing retreatment case that needs a 3D view before you commit to a plan.

Can I measure canal length and working length accurately on CBCT?

Yes. Measurements are calibrated from the voxel spacing stored in the DICOM header, so a linear measurement from the orifice to the apex reflects true millimeters, not a scaled screen estimate. This does not replace electronic apex locator readings taken during treatment.

Does it detect vertical root fractures automatically?

There is no automated fracture detection. What CBCTHub gives you is unlimited oblique cross-sections perpendicular to the root axis, which is how vertical root fractures and the associated J-shaped bone loss are actually read — by scrolling through thin slices, not by an algorithm flagging a box.

What field of view (FOV) does it support?

Any FOV a scanner exports as standard DICOM, from small volumes (40×40mm and below, typical for single-tooth endodontic protocols) up to full-arch and craniofacial volumes. CBCTHub also reads proprietary exports from Carestream, Planmeca, Vatech, Sirona, Morita and NewTom.

Can I compare a pre-treatment CBCT with a recall CBCT for the same tooth?

Yes. Open both studies in separate tabs, or use the built-in comparison view to align the same slice position across two exams — useful for tracking periapical lesion healing at the 6- or 12-month recall.

Is CBCTHub compliant for handling patient imaging data?

Processing happens locally in the browser — the DICOM study is not uploaded unless you explicitly generate a share link. CBCTHub supports HIPAA-aligned and GDPR-aligned workflows including access logs, encrypted storage for shared studies, and a signable Data Processing Agreement.
