Abstract: A dental inspection apparatus includes a first rectangular elongate body portion and a second rectangular elongate body portion. The first body portion is defined by a first top surface, a first bottom surface a first body length, a first body width and a first body thickness. The second body portion is defined by second top surface, a second bottom surface, a second body length, a second body width and a second body thickness. The first body portion is joined to the second body portion approximately at a midpoint of the length of the second body portion such that the first body portion is substantially perpendicular to the second body portion and such that the first top surface and the second top surface form a contiguous joined top surface. The joined first and second body portions define one or more contiguous reflective surfaces substantially reflective to impinging light.
