The matrix is thinned in its cental regions to permit a filling to be made which has close con tact with an adjacent tooth. A light transparent wedge has also been invented which selectively conducts light to the base of the tooth preparation and which can be used to conduct light interproximally which light has been applied at either end of t he wedge.
