Description
Levin Stolz and colleagues model how light travels through human dentin in a 2026 study. Dentin, the layer under tooth enamel, holds a dense network of tiny tubules in an organic and mineral matrix, causing light to travel differently by direction. Older models that assumed uniform travel missed that angular effect and misjudged optical properties.
The team built a combined isotropic and anisotropic Monte Carlo model, fitting it to angle-resolved measurements from three human teeth across visible wavelengths. Tubule diameter near 2.25 micrometres and densities from 19,000 to 60,000 per square millimetre were characterised. Ignoring direction-dependent travel caused absorption errors above 40 percent. The model should sharpen dental imaging and early cavity detection.
