Abstract:
Objective To investigate the values of the multi-planar reformation(MPR), volume rendering (VR) and maximum intensity projection (MIP) following multi-slice computed tomography (MSCT) examination in the diagnosis and therapy of impacted tooth. Methods Ten patients confirmed with impacted tooth by X-ray film were scanned with MSCT and the data were sent to the workstation for reconstruction of the MPR, VR, and MIP. Results MPR was able to demonstrate the relative bone intensity around the implanted tooth and exactly determine the distance of impacted tooth with the buccolingual bone wall or adjacent teeth. VR directly displayed the three-dimensional position of the impacted tooth and its relationship with the adjacent teeth. MIP displayed the anatomic structure of the impacted tooth and the bone density around it. Conclusion Combination of MPR, VR, and MIP can directly and accurately demonstrate the location of the impacted tooth and its anatomic relation with the adjacent teeth, providing reliable information for surgical and orthodontic treatment.
