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.
