Conservative interproximal box-only polyacid modified composite restorations in primary molars, twelve-month clinical results

The treatment of proximal caries has changed during the last decade. The pr esent study evaluates a recently developed material, applied in box-only pr eparations in primary molars. Al the twelve-month evaluation of this clinic al study, it became obvious that Dyract can bt an alternative for Tytin in the primary dentition, though there is some change in color of the Dyract m aterial. in time, the marginal adaptation of Dyract seems to improve. The p reparation time for both materials is comparable, The total treatment time of box-only Dyract restorations (including an occlusal sealant), however, i s longer compared to conventional class II Tytin restorations. Although in both groups radiolucencies were found at the baseline radiograph evaluation , no sign was found of secondary caries. One recurrent caries lesion was fo und adjacent to a Dyract restoration. It should be emphasized that one-year data do not indicate the long-term success of restorations.
