Subject: [roots] Quiz of the Day - cbCT -answer
This is where the Kodak cbCT really shines. After looking at the scan, the cuspid was far more
invoved than it initially appeared. The Saggital section is espcially interesting in that the
resorbed area clearly shows the characteristic thin layer of remaining dentin wrapped around the
pulp space. The resorption also seems to be more than half way through the tooth, though from
outward appearances, ( and probings) the tooth appears fairly normal. I enclose two slices from
the cbCT volume set.
Three advantages have been gained by taking the cbCT
(1) In combination with the pulp tests - we determine that the lateral incisor does NOT need endo
(2) By determining that the cuspid is not restorable, we give the patient a more accurate prognosis
without performing invasive flap surgery, thereby preserving optimal gingival contours for the
eventual implant
(3) By forwarding this cbCT to the clinician placing the implant, we save the patient further
radiographic examination ( and exposure). The cbCT volume can now be used to plan the implant placement.
