Abstract
A device for estimating the thickness of rigid material in a tooth covering the pulp of the tooth. The device comprises a light source arrangement configured to emit light at a first wavelength and light at a second wavelength onto the tooth and a sensor arrangement for measuring the intensity of light reflected and scattered from the tooth corresponding to the first and second wavelengths. The device also comprises a processor configured to receive a first intensity map corresponding to the first wavelength and a second intensity map corresponding to the second wavelength from the sensor arrangement, analyze the first intensity map and the second intensity map to asses the amount of light reflected and scattered from the tooth corresponding to the first wavelength and the second wavelength and estimate an indication of thickness for the rigid material covering the pulp of the tooth based on the analysis.
