Radioolucent dental dam clamp

A dental dam clamp kit comprising a plurality of radiolucent dental dam clamps (of differing colors) of the type having a pair of lateral wings lying substantially in a common plane and being substantially symmetrical about a center line, each of the wings having an interior surface adapted to lie against and hold a dental dam tightly against a tooth, the wings being joined by a spring-like transverse bridge, wherein said dental dam clamps comprise flexible radiolucent plastic having sufficient flexural strength to hold said dental dam against said tooth such that moisture leakage through the dam-tooth interface is substantially prevented while retaining the ability to return to its original shape when removed from the tooth, the kit including a number of such dental dam clamps pigments so as to differ in color from each other, the color difference being identifiably indicative of clamps of different size and/or shape for use on teeth of different size or in different dental applications.
