A Segmentation and Classification Scheme for Single Tooth in MicroCT images based on 3D Level Set and K-means++

The tooth is one of the most important structures in the human mouth. There are a lot of diseases with the tooth, and vertical root fracture (VRF) is a severe disease in human tooth. VRF is defined as a longitudinal fracture confined to the root that usually begins on the internal canal wall and extends outward to the root surface (Yang et al., 1995). VRF is a common complication in root canal-treated teeth (Karygianni et al., 2014; Tamse, 2008). This leads to major damage to the periodontium. There exists substantial clinical evidence that VRF also generates a vertical destructive lesion (Lustig et al., 2000; Tamse et al., 2006).
