title: A three-year clinical assessment of a composite resin and its radiopaque counterpart.
abstract: Two composite resin materials, one containing a radiopaque filler, gave similar clinical results over the 3 year test period. There was a color shift toward a darker restoration, and a marginal stain occurred. Loss of marginal integrity was slight, and only three restorations showed wear or loss of material. There were no recurrent caries. It should be reemphasized that the major advantage of the radiopaque material is the capability of radiographic evaluation. Voids, caries, improper contours, and overhangs may be detected with this material.
