The more I stare, the more I see the internal structures of the tooth. No face there.
Would be better if it’d be a tomographic image.
Thought… those around-the-head panorama xrays… could the machines be turned into tomographs, with some software processing thrown at the acquired image? What changes would be needed on the machines?
Another thought… metal crowns are xray-opaque. Could the teeth underneath be imaged by neutrons? Or the tooth-crown bond examined by ultrasound, like composites and metals and joints are tested in industry?
