New Endodontic Technologies

New Technologies: Kodak 9000 3D (High-Resolution Cone Beam Computed Tomography)

Our new Kodak 9000 3D with focused beam technology.Our new Kodak 9000 3D is an extraoral imaging system that aids in the diagnosis and treatment of complex endodontic cases. The system's advanced CMOS detector produces low-dose, high-resolution 3D CBCT images.

In the 3D mode, the Kodak's 9000 3D's unique localized field of view limits radiation while providing volumetric studies of small areas of the jaws and supporting structures. Reconstruction of the images using a voxel (VOlume piXEL) size of 0.076 mm results in high-resolution images for more accurate diagnoses and improved treatment planning.

Additional benefits of the Kodak 9000 3D include:

1.) Precise visualization of dental structures in their actual spatial representation. Displaying axial, coronal, sagittal, and cross-sectional images, the unit provides 3D reconstructions that accurately depict structures in their actual relationships to improve diagnosis.

2.) Radiation that is more than 100 times less radiation than a medical CT scan.

3.) Reconstructions of 3D images in under 40 seconds, with real-time viewing of the image as it is being recorded.

4.) Ability to print, transfer image data via optical media (CD) for viewing with an imbedded viewing applet, and send screen "snapshots" of significant findings by email.

Comparison of the effective radiation dose necessary to image with various modalities are listed below:

CBCT is between 30 and 400 µSv*

Medical CT of the maxilla and mandible is 2,100 µSv

Full mouth series F Speed Film < 0.033 mSv
Direct Digital Detector Varies; up to 90% reduction over “D” speed film
Bitewings (4 films)
F Speed Film < 0.007 mSv
Film-based panoramic radiograph 0.007 mSv
Chest x-ray 0.01 mSv – 0.05 mSv
Skull x-ray 0.1 mSv – 0.2 mSv
Abdominal x-ray 0.6 mSv – 1.7 mSv
Barium exam 3 mSv – 8 mSv
Head CT 2 mSv – 4 mSv
Body CT 5 mSv – 15 mSv


NOTES:
Annual dose equivalent by dental imaging in US: 0.03 mSv/year
Average natural background radiation in the US: 3 mSv/year (.01 Sv/day)
General public exposure limit: 1 mSv/yr
Pregnant women: whole-body effective dose limit of 5 mSv/9 months
Average galactic and cargo radiation from 5-hour flight at 35,000 feet: 0.03 mSv
Average radiation from galactic radiation in Denver, CO: 0.510 mSv/year
FMX with F-speed film is equivalent: 3 days of background radiation exposure

*A millisievert (mSV) measures the biologic effects of radiation and allows comparison between radiation exposure of a portion of the body with radiation exposure of the entire body, as opposed to the physical aspects, which are characterised by the absorbed dose, measured in grays.

1000 mSv = 1 Sv

Frequently used multiples are the millisievert (1 mSv = 10–3 Sv) and microsievert (1 μSv = 10–6 Sv).
