Abstract
A method and an apparatus for detecting distance of a probe contacting a tooth surface to pulp of a tooth by determining an indication of thickness of dentine of the tooth is provided. The method comprises illuminating the dental tissue of the tooth with a probe, then receiving the data representing scattered light from the dental tissue. A spectra of the scattered light is then obtained and analyzed to further obtain a spectral analysis re-suit. An indication of the thickness of the dentine of the tooth is then determined based on the spectral analysis result. The method may help to prevent the unintended exposure of pulp during dental treatments such as drilling.
