Description
Commander John S. Evered, DC, USN and Commander Terry Webb, DC, USN
Purpose
Computed tomography (CT) was invented by Sir Godfrey
Newbold Hounsfield and Allan McLeod Cormack
working independently in the late 1960' s and early
1970's. They shared the Nobel Prize for Medicine in
1979 for this discovery. It was developed as a way to see
a "slice" of a patient's body which was not available before
with two-dimensional radiographs. CT machines are
relatively large and expensive and expose the patient to
high doses of radiation. Cone beam CT (CBCT) was
developed in the late 1990' s as an outgrowth of computed
tomography. It offers reduced radiation exposure and
scan time. Cone beam CT was approved by the FDA in
2000, and then introduced to North American dentists in
2001. Since then, it has presented new opportunities in
endodontic diagnosis and treatment planning. This clinical
update will define cone beam CT, present its diagnostic
abilities compared to conventional two dimensional
radiographs, and explain its endodontic applications.
