2-YEAR RESULTS WITH BOX-ONLY RESIN COMPOSITE RESTORATIONS

One of the restorative alternatives in the treatment of proximal cario us lesions is the box-only approach. This paper describes baseline and two-year results with 68 box-only resin composite restorations in a c linical study. The restorations were made using a glass ionomer cement as a dentin replacement and a bevelled outline. In terms of treatment time (32 minutes) and postoperative sensitivity (4 cases), the box-on ly restorations show favorable properties in comparison to conventiona l Class II resin composite restorations. At the two-year assessment no failures were observed, with fair results regarding clinical characte ristics. It is concluded that, although applied to a limited number of teeth, the results indicate that the box-only approach with resin com posites may make a contribution to the tooth-tissue-saving, restorativ e techniques.
