- Nonsurgical endodontic therapy of a right mandibular first molar with 3 distal roots was successfully performed with
the aid of magnification. 3D data (DICOM format) of the tooth were obtained from a CT HighSpeed Advantage and a Denta
Scan program produced by GE Medical Systems. The CT protocol used for this procedure involved a slit thickness of 1 mm.
The 3D digital data obtained were fed into a visualization program (V-works; Cybermed Co) and then exported to the rapid
prototyping machine for fabrication of the actual-sized tooth model. The material for the model-making process was starch.
The 3D digital visualization and the computer-aided rapid prototyping (CARP) model clearly showed 3 separate distal roots
(distobuccal, distolingual, and middle distal). The CARP technique seems to be a useful imaging technology to document
unusual root anatomy in clinical dentistry.
