摘要：
A method (300) for detecting one or more caries using an imaging device (10), the method including the steps of: (i) directing (320) light from a first light source (12) toward a tooth (40)； (ii) measuring (340), with an optical sensor (16), transmission of light from the first light source through the tooth； (iii) directing (330) light from a second light source (14) toward the tooth, wherein the second light source directs light at the tooth at a different angle relative to the first light source； (iv) measuring (350), with the optical sensor, reflectance from the tooth of light from the second light source； (v) comparing (360) the measured transmission to the measured reflectance； and (vi) determining (370), based at least in part on said comparison, whether a caries is present in the tooth.
