  • Sub-surface visualization device
    Patent number: 5429120
    Abstract: The invention relates to a device and method for increasing the visualization of biological tissues and underlying structures. A particular application is to examine gums for pre-emergent teeth. One embodiment has a cylindrical lens portion and an offset handle which may also serve as a port of entry for light sources to brighten the viewing area. The method involves pressing body tissue with the device which serves to vacate the area of blood which increases light transmission through the tissue and enhances contrast between bone/teeth structure and flesh.
