| Abstract: |
| ［Objective］ Using CT scanning and 3D reconstruction to establish 3D digital model of tooth and pulp in Boolean. ［Methods］ The teeth were scanned and the digital model was established. ［Results］ The 3D digital model of pulp was set up successfully. ［Conclusion］ CT scanning combined with 3D digital model of pulp, is an accurate, non-invasive method to evaluate the effects of root canal preparation. |
