Abstract

During the caries treatment, three-dimensional measurement of tooth profile and caries location is one of key steps in the therapeutic process of caries. We propose a three-dimensional vision measurement of tooth crown and dental caries with line structured light. First, an integrated calibration using right angled spot target is executed and the parameters are obtained rapidly. Subsequently, the profile of the tooth crown is reconstructed and the dental caries area is identified. The results show that the reprojection error could reach tens of micrometers and the caries’ area is measured as ~ 2.83 mm2. These results indicate high potential in the diagnosis and treatment of dental caries.
