An apparatus for suitable for obtaining an image of a dental structure has an illuminator member placed proximate the area to be imaged. The illuminator member has a support structure () for retaining the illuminator member in position proximate the area to be imaged. A reference () is coupled to the support structure () of the illuminator member and disposed within the area to be imaged. At least one light source () is coupled to the support structure () of the illuminator member for directing imaging illumination toward the area to be imaged. A camera () records an image from within the area to be imaged using the imaging illumination from the illuminator member, wherein the image comprises the reference ().

Apparatus for dental shade measurement

A ring illuminator () has a light channeling section () with an input face () optically coupling the light channeling section () to a flash unit () of a camera () for obtaining flash illumination therefrom. A ring section () is optically coupled to the light channeling section and extends around an aperture for fitting the ring illuminator around a lens (). The ring section has a rear surface () for positioning toward the body of the camera. The rear surface has a plurality of light redirecting features () for redirecting at least a portion of the flash illumination from within the ring section outward from the camera, around the lens of the camera.

Ring light guide

In a digital camera having a rectangular electronic display for framing pictures, a dental positioning grid comprising: a line pattern superimposed on the rectangular electronic display, the line pattern including a horizontally centered horizontal line extending substantially the width of the display, a short vertical line intersecting the horizontal line at its midpoint, and long left and right vertical lines intersecting the horizontal line at substantially &#xbc; of the display width distance respectively from the left and right sides of the display.
