Abstract

Dental imaging systems include an optical scanner that scans one or more interrogation beams across a portion of at least one tooth to produce a dentally modulated light flux associated with light scattering, absorption, or other interaction of the interrogation beam and a tooth interior. The dentally modulated light flux is detected and processed to produce picture information associated with the tooth. Interrogation wavelengths between 800 nm and 1800 nm can be used to provide images suitable for diagnosis and assessment of demineralization or other defects. Interrogation beams at one or more wavelengths can be used. Multiple detectors can be situated to receive dentally modulated light fluxes at different wavelengths or dentally modulated light fluxes with different directions or different locations. Markers at or on a tooth can be used to for depth determination. Index matching to the tooth can improve image quality.

Description

[0001] cross reference [0002] This application claims priority to US Provisional Application No. 60 / 748809, filed December 8, 2005, which is hereby incorporated by reference. technical field [0003] The present invention relates to a method and apparatus for creating images of teeth for diagnostic and therapeutic purposes using infrared light. Background technique [0004] X-ray imaging is useful in dentistry because it shows information about the inside of the tooth. This information includes cavities and pores in the tooth tissue, as well as demineralized areas where the mineral content of the tissue decreases and the tissue becomes porous, typically due to acid exposure of the tooth. X-ray imaging is effective because hollowed and demineralized areas are more transparent to x-rays than surrounding tissue, and thus transmit the higher intensity x-rays emanating from the source, along with utilizing Mineral areas intersecting adjacent paths of incoming rays create stro...
