segmentation different structure of individual tooth

To get the root volume, I would recommend to segment the entire tooth as described in these topics:

Teeth Segmentation

Is there a easier way of segmenting multiple teeth easily like shown here from a CBCT ? [3D Tooth Segmentation Tool: How to segment many teeth easily] I tried thresholding and grow from seed, fill between slices and filling holes and applying smoothes. While we can segment out single tooth after spending like 15 minutes on 1 teeth with good results it is not easy to do this for all the teeth. Is there a easier way like as shown here in the youtube ? Also if someone has done tee…

Segmentation algorithm used in 3D Slicer

Hi, I’m using 3D Slicer for tooth segmentation and I’ve created an stl model from ct scan (DICOM). I’ve done that using Segment editor module. Can someone tell me which segmentation algorithm is used in slicer to create an stl model from ct scan?

You should be able to then split the segment between the root and enamel using thresholding. If the image quality is not sufficiently good then you may need apply smoothing and/or apply manual touch-ups. You may also try Grow from seeds and Watershed effects with seeds placed in the enamel and outside.

@manjula have you tried to segment the enamel? Do you have any specific suggestions?
